OVERVIEWTruss Components & Code RecognitionTruss ComponentsUnique Chord SectionsPatented FastenersThe symmetrical shape of TrusSteel’s patentedU-shaped chord sections provides nearly equalchord member moment capacity in both in-planedirections. The TrusSteel chord members havesuperior bending strength in out-of-planedirections. These characteristics combine tocreate an efficient truss that is exceptionallystrong and stiff. The recent addition of specialchord sections for short span / low loadconditions and for long span / high lowconditions improves the value engineering of theentire system.TrusSteel is the only CFS truss system in theindustry using Double-ShearTM fastenertechnology. This patented technology provides arigid, bolt-like connection at all chord/webintersections and is specially designed to resistmovement and back-out. Color-coded, markedfasteners create the most dependable, easilyinspected connection available for CFSmaterials.Structural ConnectionsTrusSteel delivers a full line of truss-to-truss andtruss-to-bearing connectors that provideconsistent quality and structural values.WebsTrusSteel utilizes both commercial grade closedtube webs and proprietary roll-formed z-webs todeliver the most cost effective roof system. Bothproducts have unique “double symmetric”properties which contributes to the strength,stiffness and stability of the truss as well asreducing lateral bracing.The industry’s most extensive library of StandardDetails describing our connections, connectors andsection properties is available in various CAD formatson CD or from www.TrusSteel.com.Code RecognitionTrusSteel members are designed and built in compliance with ASTM A370, ASTM A653, ASTM A500,ANSI Standards, and voluntary standards as described in our own reports from UnderwritersLaboratories (UL) and ICC Legacy reports (NER and Florida Product Approval).

A P P L I C AT I O N SHospitality / EldercareThe Inn on Biltmore EstateLuxury HotelAsheville,NCOver 35,000 SF of TrusSteel trusses top the new Inn on BiltmoreEstate. Located on a national historic site, quality and ease ofinstallation were of paramount importance to the owner.Unusual framing situations, including radial and conical roof areas,provided challenges met by the truss fabricator and TrusSteelengineering team.Design FlexibilityThe pre-engineered TrusSteel system allows much greater designflexibility than steel “C” truss framing. As a result, you can design infamiliar roof lines - pitched or flat, with hips, gables, gambrels,monos, mansards, cantilevers, overhangs, scissors - as well as floortrusses. This design flexibility makes TrusSteel ideal for almost anybuilding type.Noncombustible TrusSteel trusses provide integral, recognized fireresistance that does not fade with time. Useful, cost-saving ULListed roof and floor assemblies can help you meet the needs ofdemanding building types, owners and codes. For more informationon UL Listed assemblies, see Section 3 of this Manual.The GarlandsAssisted-Living CommunityBarrington, ILOver 150,000 SF of TrusSteel trusses helped to create the “FrenchCountry” style of this campus. One of the many TrusSteel UL Listedassemblies met the architect’s and owner’s requirements for fireprotection.123456782.03

A P P L I C AT I O N SMunicipal / InstitutionalGolden City StationFire StationLouisville, KYThe design of this fire station required long, clear spans andnoncombustible framing. The truck bay areas were covered with 85-footclear span TrusSteel trusses. For ease of shipment,these trusses were shop fabricated in two halves thatwere then connected together in the field by theinstaller.PGA HeadquartersHistorical CenterPort St. Lucie, FLThe new showpiece of the Professional GolfersAssociation headquarters campus is the PGA HistoricalCenter. TrusSteel trusses were selected for their highquality and overall economy of installation.Coral Baptist ChurchNew Church ComplexCoral Springs, FLThe truss systems for the many roofs over this new worship,education and fellowship complex contained just about every typeof truss under the sun. There were piggybacked trusses, flats,drags, hips, commons, monos and radials - with about everybearing condition imaginable, including heavy steel, CFS steel, barjoists and masonry. Because of the design flexibility of TrusSteelCFS trusses, they interfaced well with all these types of framingsystems.12.042345678

Fifty-foot trusses framed in a radial pattern created large,open living areas.TrusSteel CFS trusses are among the lightest and strongest steelframing made. They are an excellent alternative to heavier steelframing and trusses, such as “C” stud trusses or stick framing.Because of their superior lateral stiffness and high strength-toweight ratio, TrusSteel common trusses, in short spans, may belifted and installed without the use of a crane. This can provide asignificant benefit on small projects or structures built in areaswith limited access.123456782.05

SPECIFYING / DESIGNINGSpecifications & Design OverviewSpecifying CFS TrussesPre-Engineered TrussesCold-Formed Steel (CFS) trusses should bespecified as “pre-engineered” trusses. The term"pre-engineered" reflects the concept of adesired outcome, where the individual trusseshave been fully analyzed and engineered to meetall specified load conditions. Individual trussdesigns should be sealed by a ProfessionalEngineer who is registered in the state where theproject is located.Pre-Fabricated TrussesCFS trusses should also be specified as “prefabricated cold-formed steel (CFS) trusses”.Trusses should be fabricated in a shopenvironment with experienced fabricationpersonnel. Trusses that are fabricated at the jobsite should not be allowed. TrusSteel endorsesindustry truss shop quality control standards asdeveloped by the SBCA’s Cold-Formed SteelCouncil.several reasons. In the code standards for theseproducts (AISI, COFS, ICC, etc.), these productsare now referred to as cold-formed steel. Inaddition, the gauge system of referencingmaterial thicknesses is becoming obsolete andhas been replaced with mil thicknessdesignations.Industry StandardsThe specifier should assure that all applicableindustry standards are referenced within theproject specification. All applicable loads andload conditions, as well as all other performancecriteria, applicable codes, building use andgeometry, etc. should be clearly defined withinthe specifications and project design drawings.For a further discussion on required information,please see “Information Required for TrussDesign”.The terminology “cold-formed steel” is replacingthe old terminology of “light gauge steel” forDesign and Review ProcessRequirementsTruss Package SubmittalDue to its importance in the overall success of aproject, it is worth repeating that the BuildingDesigner must clearly state, in the plans andspecifications, all specific requirements for thetrusses. This clear and thorough communicationof performance criteria will help truss suppliers,general contractors and truss installers providemore accurate pricing, preliminary designs, andultimately a better product on the project.As a tool for the specifier, a complete GuideSpecification for TrusSteel, written instandard three-part format, is available onthe CD version of this manual.13.012Once the truss designs have been completed andsealed by a professional engineer, the designswill be submitted to the Building Designer forreview and approval. If the Building Designer issatisfied with the truss submittal, then the trussmanufacturer will begin fabricating the trusses. Ifthe Building Designer is not satisfied, the trusssubmittal will be rejected and returned to thetruss manufacturer along with preciseinstructions on corrective action. The trussmanufacturer will make the necessaryTruss Designcorrections and then resubmit the trusses to theProject plans and specifications will eventually Building Designer. This process will continuebe sent for pricing to companies involved in the until the Building Designer approves the trussmanufacture of CFS trusses.
