TrusSteel is the most accepted, most specified cold- formed steel (CFS) truss system on the market today. No other building component combines strength, stiffness, fire resistance, insect resistance and design flexibility so well.

The unique, patented truss chord shape and Double- ShearTM fasteners, combined with multiple types of web shapes, make TrusSteel CFS trusses, pound-for-pound, the strongest and stiffest cold-formed steel trusses on the market. Not surprisingly, these same characteristics combine to create a light, economical steel building component having exceptional load-span capabilities, with clear spans in excess of 80 ft.

Supported by powerful Alpine steelVIEWTM design and analysis software, TrusSteel CFS trusses provide reliable, economical structural solutions for almost every roof or floor application.

TrusSteel is proud to introduce ARC™ curved trusses. ARC trusses offer smoothly-curved (not segmented) top and/or bottom chords that make these trusses the perfect solution for framing curved roofs, arched or barrel-vaulted canopies, or any design element with an arc or radius curve.

ARC trusses can clear span over 80 feet (depending upon configuration). Overhangs or cantilevers are no problem. For tall roofs, ARC trusses can work in piggyback truss situations. For long spans, ARC trusses can be fabricated and shipped in sections and spliced at the job site.

ARC trusses provide smoothly-curved chords, so you no longer need the clumsy and expensive overbuilding that is frequently required to create smooth curves on straight or segmented chord trusses. This feature can save quite a bit of time and money in the field, and means that you can start getting your roof installed in a more timely manner.

As is the case with all TrusSteel trusses, each ARC truss is pre-engineered to the exact specifications of your project. Truss installation layouts and complete, sealed shop drawings are available for each design. Engineered designs for permanent bracing and rafting lifts are available from local TrusSteel Authorized Fabricators.

Each ARC truss is fabricated in a shop environment, so you can expect consistent curves from truss to truss. And, the smooth curves of ARC trusses look great in designs where the truss is exposed to view in the finished building.

The symmetrical shape of TrusSteel's patented U-shaped chord sections provides nearly equal chord member moment capacity in both in-plane directions. The TrusSteel chord members have superior bending strength in out-of-plane directions. These characteristics combine to create an efficient truss that is exceptionally strong and stiff. The recent addition of special chord sections for short span / low load conditions and for long span / high low conditions improves the value engineering of the entire system.

TrusSteel utilizes both commercial grade closed-tube webs and proprietary roll-formed z-webs to deliver the most cost effective roof system. Both products have unique 'double symmetric™ properties which contributes to the strength, stiffness and stability of the truss as well as reducing lateral bracing.

TrusSteel is the only CFS truss system in the industry using Double-ShearTM fastener technology. This patented technology provides a rigid, bolt-like connection at all chord/web intersections and is specially designed to resist movement and back-out. Color-coded, marked fasteners create the most dependable, easily inspected connection available for CFS materials.

TrusSteel delivers a full line of truss-to-truss and truss-to-bearing connectors that provide consistent quality and structural values.

Reconstruction of the Pentagon began immediately after 9-11, with all parties committed to completing the restoration within 12 months.

The Pentagon reopened on-time, on-budget, on the very hard work and cooperation of everyone involved.

Seven entire roofs were built on the ground and lifted into place, complete with trusses, bracing, decking and mechanicals. This installation technique is called rafting. See Section 7 for more information. Estimated time savings on the project: two weeks.

Rafting (assembling entire sections of the roof system on the ground and lifting into place) allowed this contractor to meet deadlines set by the short building season in Alaska. Structural design of the truss system, lifting bracing, permanent bracing and all connections was done by TrusSteel.

Over 35,000 SF of TrusSteel trusses top the new Inn on Biltmore Estate. Located on a national historic site, quality and ease of installation were of paramount importance to the owner.

Unusual framing situations, including radial and conical roof areas, provided challenges met by the truss fabricator and TrusSteel engineering team.

Over 150,000 SF of TrusSteel trusses helped to create the 'French Country™ style of this campus. One of the many TrusSteel UL Listed assemblies met the architect's and owner's requirements for fire protection.

The design of this fire station required long, clear spans and noncombustible framing. The truck bay areas were covered with 85-foot clear span TrusSteel trusses. For ease of shipment, these trusses were shop fabricated in two halves that were then connected together in the field by the installer.

The new showpiece of the Professional Golfers Association headquarters campus is the PGA Historical Center. TrusSteel trusses were selected for their high quality and overall economy of installation.

The truss systems for the many roofs over this new worship, education and fellowship complex contained just about every type of truss under the sun. There were piggybacked trusses, flats, drags, hips, commons, monos and radials - with about every bearing condition imaginable, including heavy steel, CFS steel, bar joists and masonry. Because of the design flexibility of TrusSteel CFS trusses, they interfaced well with all these types of framing systems.

Collaboration between engineers at Freightliner, TrusSteel and the local truss fabricator resulted in a state-of-the-art design framed completely from TrusSteel products.

This campus of new elementary and middle schools included over 112,000 SF of TrusSteel trusses. TrusSteel cold-formed steel (CFS) trusses offer the features of non-combustibility, UL-Listed assemblies and recycled content demanded on many school projects.

Over 12,000 SF of TrusSteel trusses shelter this new home in the desert. Fifty-foot trusses framed in a radial pattern created large, open living areas.

TrusSteel CFS trusses are among the lightest and strongest steel framing made. They are an excellent alternative to heavier steel framing and trusses, such as 'C™ stud trusses or stick framing. Because of their superior lateral stiffness and high strength-to- weight ratio, TrusSteel common trusses, in short spans, may be lifted and installed without the use of a crane. This can provide a significant benefit on small projects or structures built in areas with limited access.
