Abstract

This specification covers metallic-coated, painted metallic-coated, and painted nonmetallic-coated steel sheet used in the manufacture of cold-formed framing members, such as, but not limited to, studs, joists, purlins, girts, and track. The steel sheet is available in the following designations: Structural Grade 50 Type H (ST50H), Structural Grade 340 Type H [ST340H], Structural Grade 40 Type H (ST40H), Structural Grade 275 Type H [ST275H], Structural Grade 37 Type H (ST37H), Structural Grade 255 Type H [ST255H], Structural Grade 33 Type H (ST33H), Structural Grade 230 Type H [ST230H], Structural Grade 50 Type L (ST50L), Structural Grade 340 Type L [ST340L], Structural Grade 40 Type L (ST40L), Structural Grade 275 Type L [ST275L], Structural Grade 37 Type L (ST37L), Structural Grade 255 Type L [ST255L], Structural Grade 33 Type L (ST33L), Structural Grade 230 Type L [ST230L], Nonstructural Grade 33 (NS33), and Nonstructural Grade 230 [NS230]. The ordered thickness shall be the base metal thickness. The base metal shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, molybdenum, vanadium, columbium, and titanium, as determined by heat and product analyses. Mechanical and corrosion tests shall be performed as prescribed. The base metal shall also conform to the mechanical property requirements including yield strength, tensile strength, and elongation. Coating requirements such as coating weight [mass], corrosion standard, thickness, flexibility and adhesion, are specified.
