1.1 This specification covers the general requirements that, unless otherwise specified in the product specification, apply to steel sheet in coils and cut lengths, metallic-coated on continuous lines by the hot-dip process. The product is intended for applications requiring corrosion resistance. The product specifications contain requirements for specific strength levels, heat resistance, paintability, or formability, or a combination thereof.
1.2 Subject to individual product specification provisions, steel sheet is available as Commercial Steel (CS) Types A, B, and C, Forming Steel (FS), Drawing Steel (DS), Deep Drawing Steel (DDS), Extra Deep Drawing Steel (EDDS), High Temperature Steel (HTS), Structural Steel (SS), and High Strength Low Alloy Steel (HSLAS). Steel sheet is produced with the following metallic coatings. Specific information on each of the following is contained in the individual product specification:
1.2.1 Zinc or zinc-iron alloy coated,
1.2.2 Zinc-5 % aluminum alloy coated,
1.2.3 55 % aluminum-zinc alloy coated,
1.2.4 Aluminum or aluminum-silicon alloy coated,
1.2.5 Zinc-aluminum-magnesium alloy coated.
1.3 Products covered by this general requirements specification are described in the following product standards: Specifications A463/A463M; A653/A653M; A755/A755M; A792/A792M; A875/A875M; A929/A929M; A1046/A1046M; A1057/A1057M; A1063/A1063M; and A1079.
1.4 Metallic-coated steel sheet is produced to various coating designations, as shown in the individual product specifications. Except for differentially coated sheet, the coating is always expressed as the total coating of both surfaces.
1.5 In case of any conflict in requirements, the requirements of the individual product specifications shall prevail over those of this general specification.
1.6 The purchaser is permitted to specify additional requirements that do not negate any of the provisions of this general specification or of the individual product specifications. Such additional requirements, the acceptance of which are subject to negotiation with the supplier, shall be included in the order information.
1.7 For purposes of determining conformance with this specification and the various product specifications referenced in 1.3, values shall be rounded to the nearest unit in the right-hand place of figures used in expressi
