JamStud®: A Smarter Curtain Wall Stud for Demanding Applications

JamStud®: A Smarter Curtain Wall Stud for Demanding Applications

When curtain wall framing needs to go taller, span wider, or perform in seismically active zones, the choice of framing member matters. JamStud®, manufactured by The Steel Network (TSN), is a patented curtain wall stud engineered to deliver greater strength and stiffness than conventional CFS studs — using less material in the process.

For structural engineers specifying curtain wall assemblies, JamStud offers a path to better performance, lower material quantities, and more efficient designs. SteelSmart® System’s Curtain Wall module supports the design of curtain wall framing with TSN members, giving engineers the tools to evaluate and specify JamStud within a complete wall design workflow.

What Makes JamStud Different?

JamStud’s patented cross-section geometry significantly improves both axial and lateral load resistance compared to standard curtain wall studs of equivalent gauge. The result is a member that can span taller wall heights, accommodate wider stud spacing, and handle demanding wind and seismic load conditions — all without requiring heavier gauge steel.

This structural efficiency has direct downstream benefits: fewer studs per assembly, reduced material costs, and less labor time in both fabrication and installation.

Key Performance Advantages

Increased strength and stiffness — JamStud’s enhanced section properties allow for taller walls and wider stud spacing than conventional alternatives, reducing the total number of framing members required without sacrificing structural performance.

Superior curtain wall performance — Curtain wall systems must resist wind loads and accommodate seismic drift without transferring unintended forces into the framing. JamStud’s geometry minimizes deflection under lateral loads, helping walls perform as designed under real-world conditions.

Material and cost efficiency — By achieving greater performance from lighter gauge steel, JamStud enables specifiers to reduce material quantities and overall project costs compared to standard stud substitutions that require heavier members or closer spacing.

Straightforward installation — JamStud is compatible with standard CFS construction methods and requires no special tools or modified installation sequences, making it easy to incorporate into conventional curtain wall framing workflows.

Sustainability — Using less material to achieve the same or better structural performance reduces embodied carbon and jobsite waste — meaningful advantages for projects pursuing LEED or other green building certifications.

Where JamStud Is Used

JamStud is well-suited for commercial, institutional, and industrial curtain wall applications where conventional studs are pushed to their performance limits. It has been specified on high-rise buildings requiring tall, wide-span curtain wall systems, hospitals and institutional facilities where structural reliability is critical, and projects in seismic zones where enhanced lateral stability is required.

Designing JamStud Assemblies with SteelSmart®

SteelSmart® System’s Curtain Wall module allows engineers to design non-axial-load-bearing wall framing with TSN members, including JamStud. Engineers can evaluate stud sizing, spacing, and deflection limits within the software — generating the design documentation needed to support specification, review, and construction.

SteelSmart® Framer, the BIM plugin for Autodesk® Revit®, extends this further by enabling detailed 3D modeling of curtain wall framing with JamStud members, supporting accurate material takeoffs and panel shop drawings.

NotchTrak®: Smarter Bridging and Backing for Light Steel Framing

NotchTrak®: Smarter Bridging and Backing for Light Steel Framing

Framing accuracy affects everything downstream — stud alignment, drywall installation, mechanical coordination, and finish quality. When precision is built into the product rather than dependent on field measurement, the entire construction process becomes faster and more reliable.

NotchTrak®, manufactured by The Steel Network (TSN), is a pre-notched track system that does exactly that. Designed for bridging and wall backing applications in light steel framing, it eliminates the manual measuring and cutting that slow crews down and introduce error — replacing it with factory precision that transfers directly to the jobsite.

What Is NotchTrak®?

NotchTrak is a high-strength galvanized steel track with pre-punched notches spaced to fit securely around stud flanges. In bridging applications, it slides over studs without the need for layout marks or field cutting, providing consistent stud-to-stud spacing across the entire wall assembly. It also functions as a backing system for wall-mounted fixtures and is available in multiple track sizes to suit a wide range of project conditions.

The result is a system that embeds precision into the component itself — so accuracy doesn’t depend on the experience level of the crew installing it.

Why It Matters for CFS Design and Specification

Bridging is a critical element of cold-formed steel wall design. It restrains studs against lateral-torsional buckling, distributes loads more evenly, and contributes to the overall stiffness and performance of the wall assembly. When bridging is inconsistently installed — due to field measurement errors or miscut track — the structural behavior of the wall can deviate from what was designed.

NotchTrak addresses this by standardizing the bridging installation process. The pre-punched notch spacing ensures that studs are held at the designed intervals, supporting the structural intent of the framing layout rather than leaving it to field judgment.

For engineers specifying CFS bridging systems, NotchTrak offers a product that connects design intent directly to field execution.

Key Advantages

Installation speed — Pre-punched notches eliminate the need for tape measures, chalk lines, and field cutting. Crews report significant time savings on wall layout compared to conventional bridging methods.

Consistent stud alignment — Factory-precision spacing means every stud is held at the correct interval, supporting stronger walls, more even load distribution, and reduced risk of drywall cracking downstream.

Reduced training requirements — Because the precision is built into the product, less-experienced crew members can frame accurately without an extended learning curve — improving consistency across the full labor force.

Dual functionality — NotchTrak serves both as a bridging system and a backing support for wall-mounted fixtures, reducing the number of separate products needed on complex projects.

Curtain wall applications — In curtain wall framing where flush, consistent stud alignment is critical to both structural performance and aesthetics, NotchTrak provides reliable, repeatable results across large wall spans.

Designing Bridging Systems with SteelSmart®

SteelSmart® System includes bridging design as part of its CFS framing workflow. When designing load-bearing walls, curtain walls, or floor framing, engineers can account for bridging requirements within the software and specify TSN products — including NotchTrak — that align with the structural design. This ensures that what gets specified is also what gets installed, closing the gap between design intent and field execution.

Why Cold-Formed Steel Is the Sustainable Choice for Construction

Why Cold-Formed Steel Is the Sustainable Choice for Construction

The construction industry accounts for a significant share of global carbon emissions — and the materials we specify matter. For structural engineers and designers looking to make a meaningful impact, cold-formed steel (CFS) offers a compelling combination of performance, durability, and environmental credentials that few materials can match.

SteelSmart® System is built around the TSN product line, which is manufactured from mill-certified steel with real sustainability advantages built in. Here’s why CFS deserves a place at the center of any green building strategy.

Steel Is the World’s Most Recycled Material

Steel has an unmatched recycling record. According to the World Steel Association, over 630 million tons of steel are recycled annually — and unlike many materials, steel can be recycled indefinitely without any loss of strength or performance. This closed-loop characteristic means that every CFS framing component specified today has a path to becoming part of tomorrow’s building, with no degradation in structural quality.

For projects pursuing LEED certification or other green building standards, recycled-content steel can contribute to Materials and Resources credits under the U.S. Green Building Council’s framework — a tangible benefit that supports project sustainability goals from the specification stage forward.

Cold-Formed Steel

Efficient to Produce, Efficient to Build With

Cold-formed steel framing is manufactured through a process that requires less energy than hot-rolled steel production, resulting in lightweight, precision-engineered components with consistent dimensions. On the jobsite, this translates to less material waste, easier handling, and a faster installation process — all of which reduce the overall environmental footprint of construction.

CFS framing is also fully recyclable at the end of a building’s life cycle, supporting circular economy principles that are increasingly important to owners, developers, and regulators alike.

SteelSmart® System helps engineers accurately size CFS members for the loads at hand — avoiding overspecification and the material waste that comes with it.

Built to Last

Durability as a Sustainability Metric

Sustainability isn’t only about what goes into a building at the start — it’s about how long that building performs. Cold-formed steel doesn’t decay, warp, shrink, or attract pests. It doesn’t burn. It resists mold and corrosion when properly specified and detailed. These characteristics extend the useful life of structures and reduce the lifecycle costs that owners bear over decades of occupancy.

When a building lasts longer and requires less maintenance and replacement, its overall environmental impact improves significantly. CFS is inherently suited to this kind of long-term performance thinking.

Designing for Sustainability Starts in the Software

The most sustainable buildings are the ones that are designed accurately from the beginning — with the right members, the right connections, and the right documentation to ensure they get built as intended. SteelSmart® System gives structural engineers the tools to design CFS framing systems with precision, reducing over-engineering, minimizing material waste, and supporting the kind of clear, constructable designs that perform well in the field.

Combined with TSN’s certified, U.S.-manufactured framing products, SteelSmart® System provides a design-to-specification workflow that supports greener building outcomes at every stage.

Why Cold-Formed Steel Framing Is Shaping the Future of Prefabrication

Why Cold-Formed Steel Framing Is Shaping the Future of Prefabrication

Prefabrication has become one of the most compelling strategies in modern commercial and multifamily construction — and cold-formed steel (CFS) is at the center of it. Its consistency, strength, and compatibility with engineered connection systems make it ideally suited for the speed, repeatability, and quality control that prefab construction demands.

SteelSmart® System is built to support this shift, giving structural engineers the design tools to take CFS framing from concept to construction-ready documentation — whether for panelized wall systems, floor assemblies, or modular components.

Why CFS Is a Natural Fit for Prefabrication

Labor shortages, rising material costs, and compressed project timelines have pushed the industry toward more controlled, efficient building methods. Prefabrication addresses all three by moving as much work as possible into a shop environment, reducing jobsite variables and improving installation speed.

Cold-formed steel supports this model in several important ways. It is non-combustible and well-suited for fire-rated assemblies. It is dimensionally stable, with no risk of warping, shrinking, or moisture-related callbacks that can derail a prefab schedule. And its high strength-to-weight ratio makes panels and assemblies easier to transport and handle on site. Together, these properties enable the predictable, repeatable assembly that prefab construction depends on.

Connections Are Where Prefab Performance Is Won or Lost

Prefabrication success depends on more than just the framing members. The connections that tie panels and assemblies to the primary structure — and to each other — must ensure structural continuity, accommodate building movement, and be fast to install in the field.

This is where TSN’s engineered connector systems are critical. Products like VertiClip® and DriftTrak® manage vertical deflection and lateral drift at head-of-wall and slab bypass conditions, allowing prefabricated assemblies to perform as designed under real building loads and movement. StiffClip® connectors provide reliable rigid load transfer where movement accommodation isn’t needed. All are manufactured to consistent tolerances and backed by load-rated performance data.

SteelSmart® System integrates the full TSN product library, enabling engineers to design framing layouts and specify connectors within a single workflow — generating the documentation that shop fabricators and field crews need to execute efficiently.

What SteelSmart® Adds to a Prefab Workflow

When CFS framing is headed for a prefab or panelized application, SteelSmart® System supports the process from design through documentation. Engineers can size load-bearing and curtain wall members, design shear walls, specify TSN connectors, and generate DXF layouts and design reports — all without leaving the platform.

SteelSmart® Framer, the BIM plugin for Autodesk® Revit®, extends this further by enabling detailed 3D modeling of stud layouts, connectors, bridging, and shear walls within the project BIM model. Panel material takeoffs can be exported directly to Excel, and panel shop drawings can be generated with associated material lists — exactly the kind of documentation that makes prefab coordination faster and more accurate.

The result is a design-to-fabrication workflow that reduces layout errors, shortens coordination cycles, and gives contractors the clarity they need to install CFS assemblies right the first time.

A Smarter Way to Design for Prefab

As prefabrication becomes more widely adopted across the construction industry, the demand for engineered, install-ready framing solutions will continue to grow. SteelSmart® System, combined with TSN’s CFS product line, gives design teams the tools to meet that demand — with software built for the precision that prefab requires and products engineered for the conditions it creates.

5 Myths About Load-Bearing Steel Studs — And What Engineers Should Know Instead

5 Myths About Load-Bearing Steel Studs — And What Engineers Should Know Instead

Cold-formed steel studs have become a cornerstone of modern structural framing, particularly in mid-rise construction. But despite decades of proven performance, misconceptions persist — and they can create unnecessary hesitation in design and procurement decisions.

SteelSmart® System is built to help structural engineers design load-bearing CFS framing with accuracy and confidence. Here we address five of the most common myths, and what the facts actually mean for your next project.

Myth #1: Steel Framing Is Too Complex to Design

Myth #1

Steel Framing Is Too Complex to Design

Fact: This concern often stems from unfamiliarity rather than actual complexity. SteelSmart® System is purpose-built to streamline CFS design — covering load-bearing walls, floor framing, roof framing, shear walls, and more within a single software platform. Engineers can design stud layouts, size members, specify TSN connectors, and generate documentation without jumping between tools or relying on manual load table lookups. In practice, a well-structured CFS design workflow often leads to fewer RFIs during construction, not more.

Myth #2: Steel Framing Is More Expensive Than Wood

Myth #2

Steel Framing Is More Expensive Than Wood

Fact: Material unit costs don’t tell the whole story. Steel’s high strength-to-weight ratio results in lighter structures, which can reduce shipping and handling costs. Its dimensional stability accelerates installation — especially in panelized or prefabricated assemblies — and eliminates the delays associated with wood shrinkage, warping, or moisture-related callbacks. When total installed cost is evaluated across the full project timeline, CFS framing is frequently competitive with or better than wood, particularly on mid-rise and commercial work.

SteelSmart® System supports accurate quantity takeoffs and design documentation, helping project teams make well-informed comparisons from the start.

Myth #3: Steel Framing Transmits Too Much Sound Between Units

Myth #3

Steel Framing Transmits Too Much Sound Between Units

Fact: Sound performance in CFS construction is primarily a detailing challenge, not a material limitation. With proper design — including resilient channels, sound attenuation clips, and appropriate insulation — airborne and impact noise can be dramatically reduced to meet or exceed IBC and project-specific IIC and STC requirements. TSN’s framing systems are compatible with acoustically rated assemblies, and SteelSmart® System supports the structural design of the wall and floor assemblies these details are built around.

Myth #4: Steel Is Difficult to Work With On Site

Myth #4

Steel Is Difficult to Work With On Site

Fact: Modern CFS framing is engineered for efficient field installation. Pre-punched studs simplify mechanical runs, consistent sizing makes stacking straightforward, and screw-friendly flanges reduce installation time. Unlike wood, steel requires no acclimation period — framing can begin immediately regardless of weather conditions. TSN also offers cut-to-length studs with labeled components for placement clarity, accommodating custom conditions that standard-length suppliers typically can’t support.

SteelSmart® System generates the design documentation and connection details that help contractors execute CFS framing with clarity and confidence — reducing field errors before they happen.

Myth #5: Steel Is Prone to Corrosion

Myth #5

Steel Is Prone to Corrosion

Fact: Like any structural material, steel requires appropriate product selection for the exposure conditions — and TSN’s products are fabricated using high-strength galvanized steel that provides durable corrosion resistance in a wide range of environments, including high-humidity and coastal applications. With correct specification and detailing, corrosion risk in CFS framing is minimal and well-managed. SteelSmart® System helps engineers specify the right TSN products for the conditions at hand.

Design Load-Bearing CFS With Confidence

The facts behind each of these myths point to the same conclusion: cold-formed steel is a well-understood, high-performing structural system — and the right software makes it accessible for any project type or complexity. SteelSmart® System gives structural engineers the tools to design, analyze, and document CFS load-bearing framing efficiently and accurately, backed by the full TSN product library.

Cold-Formed Steel Walls in Modular Construction: Designing for Lateral Stiffness

Cold-Formed Steel Walls in Modular Construction: Designing for Lateral Stiffness

Modular construction is reshaping how buildings are designed and delivered — and cold-formed steel (CFS) is proving to be a critical part of that evolution. Its high strength-to-weight ratio, dimensional consistency, and compatibility with offsite fabrication make CFS framing a natural fit for modular systems.

But one challenge demands careful engineering attention: ensuring adequate lateral stiffness and seismic resistance in modular assemblies, particularly when units are stacked. A 2025 study published in Structures addresses this directly — and its findings have meaningful implications for how engineers should approach CFS wall design in modular projects.

What the Research Shows

“Lateral stiffness of modular steel structures infilled with cold-formed steel walls” (full article)

The study’s key findings:

  • CFS infill walls significantly increase the lateral stiffness of modular steel frames
  • Connection detailing — specifically how CFS walls are fastened to the frame — directly affects lateral performance
  • A simplified model using axial springs to represent studs accurately predicts system behavior, validated by quasi-static full-scale testing
  • Openings such as doors and windows reduce stiffness, but the effect can be addressed through deliberate design choices

The takeaway for structural engineers: infill CFS walls aren’t just partitions — they’re active structural contributors to lateral system behavior, and their connections need to be designed accordingly.

Designing These Systems with SteelSmart®

SteelSmart® System is built to support precisely the kind of nuanced CFS design this research highlights. The software integrates TSN’s full connector and framing library, allowing engineers to design and specify systems that account for drift, deflection, and lateral load transfer within a single workflow.

DriftTrak®

Allows in-plane lateral drift and vertical deflection at the head of wall, enabling modular and panelized systems to accommodate building movement without compromising connection integrity. SteelSmart® System’s Curtain Wall module supports DriftTrak specification alongside complete stud layout design.

VertiClip® SL & SLB

Transfer horizontal forces while allowing vertical deflection of the stud relative to the structure — behavior that directly parallels the energy-dissipating stud action modeled in the study. These connectors are part of TSN’s product library within SteelSmart® System.

X-Brace Shear Wall (StiffWall®)

SteelSmart® System includes a dedicated X-Brace Shear Wall module for designing TSN’s StiffWall system, providing engineers with a direct path to specifying flat strap bracing for panelized CFS wall assemblies that need to resist lateral loads.

Design Takeaways for Modular Engineers

The research reinforces several principles that should inform how engineers approach CFS wall design in modular applications:

  • Treat infill walls as structural elements, not just enclosures — especially in stacked modular systems where lateral performance is cumulative
  • Specify engineered connectors that account for both in-plane drift and out-of-plane deflection, rather than relying on generic fastening details
  • Use software that reflects real structural behavior — SteelSmart® System is built around TSN’s tested and load-rated product line, giving engineers the tools to design with performance and constructability in mind from the start

A Software Platform Built for These Challenges

As modular construction grows in complexity, the demands on CFS design software grow with it. SteelSmart® System gives structural engineers the analytical tools and TSN product integration needed to tackle lateral stiffness challenges in modular framing with confidence — from initial member sizing through connection specification and documentation.

From Policy to Prefab: How SteelSmart® Fits Into 2026’s Construction Landscape

From Policy to Prefab: How SteelSmart® Fits Into 2026’s Construction Landscape

The construction and steel industries are navigating a period of rapid change. Sustainability mandates, supply chain pressures, shifting trade policy, and growing demand for prefabrication are all reshaping how buildings get designed and built. For structural engineers working in light steel framing, having the right software and product ecosystem in place is more important than ever.

Here’s a look at the four key forces shaping the industry — and how SteelSmart® System and The Steel Network (TSN) are positioned to help design teams stay ahead of them.

Sustainability & Decarbonization

The push to lower the carbon footprint of construction is accelerating. Projects and policies increasingly call for green building approaches, and material choices are under greater scrutiny.

Cold-formed steel is well-suited to this environment. Steel is the most recycled material in the world, and TSN works with standard mill materials that already incorporate significant recycled content. SteelSmart® System supports LEED-conscious design workflows and is built around the TSN product library, giving engineers a direct path from sustainable material specification to accurate structural design.

The Shift Toward Prefabrication

Speed, waste reduction, and quality control are driving broader adoption of prefabricated and modular construction methods. Light steel framing is a natural fit — it’s precise, dimensionally consistent, and well-suited to offsite panel fabrication.

As architects, engineers, and contractors look for systems that reduce site time and coordination risk, demand for integrated framing solutions will continue to grow. SteelSmart® System’s design modules and SteelSmart® Framer — the BIM plugin for Autodesk® Revit® — are built to support this shift, enabling engineers to move from design to panel documentation within a single connected workflow.

Supply Chain & Trade Pressures

Tariffs, trade policy, and raw material volatility remain ongoing challenges for the construction industry. Material costs and lead times can shift quickly, making reliable specification and sourcing increasingly important.

TSN is U.S.-based with multiple manufacturing locations, reducing exposure to long international supply chains. Their engineering documentation, technical catalogs, and submittals help design teams specify correctly the first time — reducing the risk of substitutions, delays, and costly field corrections. SteelSmart® System reinforces this by generating accurate design outputs that support clear, defensible specifications from the start.

Regulatory & Code Pressures

Building codes and sustainability standards are evolving rapidly. Energy performance requirements, seismic design provisions, fire ratings, and carbon accounting are all areas where the bar continues to rise.

TSN holds ICC Evaluation Service Reports (ICC-ESR) and compliance data for its connector products, and its design guides address seismic design, vertical deflection, medical facility applications, and more. SteelSmart® System is kept current with applicable standards, giving engineers confidence that their designs are aligned with the latest code requirements — and that the documentation to support those designs is readily available.

Conclusion

The forces reshaping construction — sustainability goals, prefabrication, supply chain complexity, and evolving codes — all point in the same direction: design teams need better tools and better-engineered products to keep up.

SteelSmart® System, combined with TSN’s tested and certified framing systems, gives structural engineers the software and product ecosystem to meet these demands. Whether you’re designing a complex curtain wall, specifying connectors for a modular project, or navigating new energy code requirements, having the right platform in place from the start makes every phase of the project more predictable.

Beyond Standard Framing: How SteelSmart® Supports Complex Light Steel Framing Solutions

Beyond Standard Framing: How SteelSmart® Supports Complex Light Steel Framing Solutions

Modern construction demands more than off-the-shelf components. Taller buildings, tighter tolerances, rising code requirements, and increasingly complex architectural designs require structural solutions that go well beyond generic framing details.

SteelSmart® System is built for exactly these conditions — giving structural engineers the software tools to design, analyze, and specify the full range of light steel framing systems that today’s commercial and multi-family projects require, including the engineered connector and framing systems manufactured by The Steel Network (TSN).

Engineering-Driven Design, From Software to Field

TSN develops each of its systems to solve a specific structural problem commonly encountered in construction. Rather than forcing a project to conform to a generic detail, their products are engineered to accommodate building movement, transfer loads efficiently, reduce field labor and rework, and improve consistency across projects.

SteelSmart® System reflects that same philosophy. The software is purpose-built for light steel framing design, giving engineers a structured workflow that matches the complexity of real-world projects — not just simple span calculations.

A Full Range of Systems, Designed to Work Together

TSN’s product portfolio spans far more than individual connectors, and SteelSmart® System is designed to support that breadth. Key capability areas include:

Movement & Deflection Management

Systems such as VertiClip®, VertiTrack®, and DriftTrak® manage vertical and lateral movement without compromising structural integrity or finish performance. SteelSmart® System’s Curtain Wall module supports the design and specification of these connectors, accounting for deflection limits and connection loads within a complete framing layout.

Rigid & Load-Transfer Connections

Products like StiffClip® provide reliable load paths where rigid connections are required, with options for slab bypass, head-of-wall, and specialty conditions. SteelSmart® System supports the design of these connection conditions across multiple framing modules.

Thermal & Building
Envelope Performance

TSN’s ThermaFast® system addresses thermal bridging and continuous insulation challenges while maintaining structural performance — a critical consideration in energy-efficient building design. SteelSmart® System allows engineers to integrate these framing strategies into their overall wall designs.

Advanced Framing & Structural Systems

Beyond connectors, TSN offers framing solutions including SigmaStud®, SigmaTrak®, JamStud®, PrimeJoist®, and Curtain Wall Studs. SteelSmart® System is built around this product library, enabling engineers to move seamlessly from member sizing to connection detailing within a single design environment.

Designed for the Jobsite — and for the Design Office

One of TSN’s core strengths is developing systems that perform not only on paper, but in the field — with simplified installation sequences, reduced fastener counts, clear detailing, and compatibility with common framing practices.

SteelSmart® System supports this by generating the documentation engineers and contractors need: design reports, connection details, DXF layouts, and material outputs that reduce coordination errors and support accurate field execution.

Supporting Collaboration Across the Project Team

TSN solutions are most effective when considered early in the design process, and SteelSmart® System makes early-stage design practical. By giving engineers the tools to model and analyze framing systems from the start, teams can resolve detailing challenges sooner, reduce RFIs and change orders, improve constructability, and deliver more predictable project outcomes.

A Software Platform Built for Structural Solutions

As building designs continue to evolve, having the right software to design and specify engineered framing systems is no longer optional — it’s essential. SteelSmart® System gives structural engineers the analytical power and TSN product integration needed to tackle complex light steel framing conditions with confidence.

Designing for Deflection: Curtain Wall Solutions with DriftTrak® Systems in SteelSmart®

Designing for Deflection: Curtain Wall Solutions with DriftTrak® Systems in SteelSmart®

Exterior curtain wall framing presents some of the most demanding structural challenges in cold-formed steel design — particularly when engineers must account for vertical deflection, lateral drift, and complex slab bypass conditions. SteelSmart® System is built to support the precise design and specification of these connections, including the full suite of DriftTrak® systems manufactured by The Steel Network (TSN).

In this overview, we take a closer look at three core DriftTrak solutions — DriftTrak Head of Wall, DriftTrak Bypass, and DriftTrak Post-Tensioned Slab (PTS) — and how SteelSmart® System empowers engineers to design curtain wall framing with the confidence that comes from load-rated, engineered performance data.

What Makes DriftTrak® the Right Choice for Curtain Wall Framing?

All DriftTrak products incorporate TSN’s patented Step Bushing Technology®, which enables a friction-free connection between clips and stud webs. This allows for controlled vertical deflection and lateral drift without transferring unwanted forces into curtain wall or partition framing — a critical requirement in modern high-rise and mixed-use construction.

These systems are load-rated and manufactured in the USA from mill-certified steel, giving structural engineers and specifiers the performance documentation needed to confidently design around real-world movement conditions. SteelSmart® System integrates TSN connector data, allowing designers to select and specify DriftTrak components directly within their curtain wall design workflow.

DriftTrak systems were engineered to eliminate the performance inconsistencies and installation deficiencies commonly associated with traditional deep-leg track and friction-based slide systems.

Installation Note: The DriftTrak track section does not provide wall closure; a top track is required for a complete assembly. SteelSmart® System’s Curtain Wall module accounts for this in its framing layouts and connection detailing.

The Three Core DriftTrak® Systems

DriftTrak® Head of Wall — Engineered Head-of-Wall Drift Slide Track

The DriftTrak Head of Wall system connects exterior cold-formed steel curtain wall studs to the primary structure at the head of wall, accommodating movement under both vertical and lateral forces. Using the DriftTrak track section with a DTSL slide angle, the system allows up to 2″ of vertical deflection (1″ up and 1″ down) plus free lateral drift — making it an ideal solution for multi-story curtain wall applications subject to live load and seismic movement.

Key Features:

  • Specifically designed for head-of-wall applications where vertical movement accommodation is required
  • Patented Step Bushing Technology delivers smooth, consistent vertical deflection performance
  • Load-rated mechanical attachment at each stud for reliable, documentable connection performance
  • Track and clips manufactured from cold-formed steel with hot-dipped galvanized coating for long-term corrosion resistance

When using SteelSmart® System’s Curtain Wall module, engineers can design stud layouts and specify appropriate connection hardware — including DriftTrak Head of Wall — based on project-specific load conditions and allowable drift parameters.

Drifttrak DTSL Head of Wall

DriftTrak® Bypass — Slab Bypass Drift Slide Track

The DriftTrak Bypass system allows exterior curtain wall studs to bypass a slab while remaining connected to the primary structure. It combines the DriftTrak slide track with either DTSLB slide angles or DTLB rigid angles, giving engineers the flexibility to accommodate vertical deflection, lateral drift, or rigid attachment configurations — whatever the project requires.

This system is particularly valuable in curtain wall applications where slab geometry or structural conditions make traditional head-of-wall attachments impractical. Because it can be configured for both movement-accommodating and rigid connections, it covers a broad range of project scenarios without requiring a change in product family.

Key Advantages:

  • Ideal when curtain wall framing must bypass a slab while still accounting for structural movement
  • Flexible configuration options — adaptable for drift, vertical deflection, or fully rigid attachment depending on project requirements
  • Unique combination of load-rated design performance and installation versatility
DriftTrak Bypass Application

DriftTrak® Post-Tensioned Slab (PTS) — Integrated Slab Drift Track

The DriftTrak Post-Tensioned Slab (PTS) system takes the slab bypass concept further by integrating directly into post-tensioned slabs before the concrete pour. This eliminates the need to install framing connections after pour — saving time, reducing field labor, and improving overall installation accuracy.

The PTS system incorporates the headed stud DriftTrak track with DTSLB or DTLB clip options, supporting both vertical deflection and rigid connection configurations. It is designed to work efficiently around post-tension tendons, and an optional locking angle (DT-LA) is available for cases where lateral drift accommodation is not required.

Key Benefits:

  • Time-saving installation: integrated into slab formwork before concrete pour, eliminating post-pour connection work
  • Optional locking angle (DT-LA) for rigid lateral configurations when drift accommodation is not specified
  • Load-rated mechanical attachment at each stud with patented Step Bushing Technology
  • Eliminates loose friction assemblies and post-installed connections into concrete, simplifying installation and improving field performance
  • Manufactured with certified cold-formed steel and hot-dipped galvanized coating for maximum durability

Designing DriftTrak® Systems with SteelSmart® Software

Whether your project requires head-of-wall movement accommodation, slab bypass capability, or an integrated post-tensioned slab solution, SteelSmart® System gives structural engineers the tools to design curtain wall framing with confidence. The software supports TSN connector data, enabling accurate specification of DriftTrak components alongside stud sizing, load analysis, and connection detailing in a single streamlined workflow.

Engineers, specifiers, and contractors benefit from software that not only models complex connection challenges but also generates the documentation needed to support review and construction — minimizing field labor, reducing coordination risk, and ensuring structural performance aligns with design intent.
