STANDARD SPECIFICATION FOR STEEL SHEET, ZINC-COATED (GALVANIZED) BY THE HOT-DIP PROCESS, STRUCTURAL (PHYSICAL) QUALITY
|Publication Date:||22 February 1991|
This specification covers steel sheet of structural (physical) quality in coils and cut lengths, zinc-coated (galvanized). Material of this qualify is intended primarily where mechanical or structural properties of the base metal are specified or required. Such properties or values include those indicated by tension, hardness, or other commonly accepted mechanical tests. Material of this quality can be produced in six grades, A through F, according to the base metal mechanical requirements (see 6.1). Grade D can be specified with or without a minimum tensile strength required (Classes 1 and 2). Class 1 product will be furnished unless otherwise specified. Structural (physical) quality galvanized sheet is produced with any of the types of coating and coating designations listed in the latest revision of Specifications A 525 or A 525M.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
