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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers coated steel sheet used in the manufacture of cold-formed framing members, such as, but not limited to, studs, joists, purlins, girts, and track.
1.2 The steel sheet used for cold-formed framing members includes metallic-coated, painted metallic-coated, or painted nonmetallic-coated.
1.3 The values stated in either inch-pound or SI units shall be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.
1.4 Unless the order specifies the “M” designation [SI units], the product shall be furnished to inch-pound units.
1.5 The text of this specification references notes and footnotes, which provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.
