These issues have <br />affected every aspect of our lives, including the materials we use <br />in construction. The use of cold-formed steel members benefit <br />the environment, contractor, designer, and developer more than <br />other material. <br />Steel is not only a recyclable product, but also a stronger product <br />that allows for longer clear-spans. Cold-formed steel is lighter to <br />provide ease of handling, and is a dimensionally stable product, <br />giving a "straight" wall with which to work. It doesn't suffer <br />fluctuation in price, making it easier to bid a project. Quality <br />control is stressed in all phases of the manufacturing process <br />so the highest possible quality is delivered to the jobsite. The <br />structural shapes manufactured are easily used for nonstructural <br />and structural wall assemblies, floor and ceiling joist assemblies, <br />trusses, and panelized systems. <br />SSMA in collaboration with the American Iron and Steel Institute <br />(AISI) has developed and adopted a standard designator system <br />for identifying cold-formed steel framing members. Using a <br />standard system will eliminate the confusion caused by individual <br />manufacturers' varied designators. <br />Technical Assistance <br />Professional technical assistance is available through SSMA or <br />individual manufacturers' technical departments. <br />Code Approval <br />SSMA structural and nonstructural cold-formed framing product <br />specifications meet the stringent requirements of International <br />Code Council Evaluation Services in conjunction with SSMA ICC- <br />ES evaluation report (ESR-3064P). The product specification and <br />documented quality control system & procedures are verified <br />during regular inspections by ICC-ES, the leader in the technical <br />evaluations for code compliance of the building products. <br />Disclaimer <br />All data, specifications, and details contained in this publication are intended as a general guide for using SSMA members' products. <br />These products should not be used in design or construction without an independent evaluation by a qualified engineer or architect to <br />verify the suitability of a particular product for use in a specific application. The SSMA and its members assume no liability for product <br />failure resulting from the use or misapplication of computations, detail drawings, and specifications contained herein. This publication <br />contains the latest information available at the time of printing with respect to the referenced building codes and standards. The SSMA <br />and its members reserve the right to make modifications and/or change materials of any of their products without prior notice or <br />obligation. For the latest information regarding a particular manufacturer's products, contact that manufacturer. All SSMA manufacturers <br />may not produce all of the products contained in this catalog. Please contact individual manufacturer to verify product availability. <br />Material Specifications <br />Structural and nonstructural members are coated to meet the minimum code requirements. Higher corrosion protection coatings such <br />as G90 are available upon request. Products manufactured by SSMA members are cold-formed from corrosion protected steel coils or <br />sheets and meet the following specifications requirements: <br />Product Type Material Specifications Min Yield Min Tensile Minimum Metallic Coating Designation <br />Nonstructural Products <br />ASTM C645 <br />ASTM A653, SS Grade 33 33 ksi 45 ksi G40 <br />ASTM A1003, Grade 33 (NS33)33 ksi ...
