Galvanized Steel Sheet Standards
Each galvanized sheet gauge number is 2 5 ounces per sq.
Galvanized steel sheet standards. Standard specification for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process1 this standard is issued under the fixed designationa653 a653m. Standard specification for steel sheet metallic coated by the hot dip process and prepainted by the coil coating process for exterior exposed building products. There are three main standards that govern the hot dip galvanized steel and a handful of supporting specifications that design engineers and fabricators should become familiar with to promote a high quality coating and ensure their steel design is suitable for hot dip. Heavier or 0037 inch thicker than the weight or thickness of the corresponding u s.
Standard specification for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process. There are three main specifications astm a123 a153 and a767 governing the coating thickness adherence and finish for hot dip galvanized steel and a handful of supporting specifications referenced in these specifications. The number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision. A755 a755m 18.
Sheets ordered by gauge weight or thickness are subject to standard thickness and weight tolerances. Avoid the galvanized steel corrugated roofing sheet rub with each other.

1 1 this specification covers steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process in coils and cut lengths. The galvanized sheet gauge is based on the u s. It is divided into specified lengths of galvanized steel corrugated roofing sheet and galvanized steel coil. There are certain specifications that have been developed for hot dip galvanizing in order to produce a high quality coating.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. It is generally iron package with moist proof paper inside and tied firmly with strap. 1 2 the product is produced in various zinc or zinc iron alloy coating weights masses or coating designations as shown in table 1 and in table s2 1. Material bend radii and minimum bend size charts.
Hot dip galvanizing is done in accordance with long established astm specifications. Standard practice for hot isostatic pressing of steel stainless steel and related alloy castings.
