Galvanized Steel Sheet Standards

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.

Galvanized steel sheet standards.

Standard gauge number regardless. Hot dip galvanizing is done in accordance with long established astm specifications. Avoid the galvanized steel corrugated roofing sheet rub with each other. There are certain specifications that have been developed for hot dip galvanizing in order to produce a high quality coating.

Standard specification for steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process. Standard specification for steel sheet complex phase cp dual phase dp and transformation induced plasticity trip zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process. 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. It is generally iron package with moist proof paper inside and tied firmly with strap.

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. Galvanized steel sheet standard jis aisi din astm bs gb length according to customers requirements common width 20 1500mm width tolerance 0mm 0 2mm thickness 0 12 2 0mm thickness tolerance 0 05mm technique cold rolled substrate and hot dipped electrolytic. The number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision. Cover design practices repair and touch up and painting powder coating over.

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. Each galvanized sheet gauge number is 2 5 ounces per sq. 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. 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.

The galvanized sheet gauge is based on the u s. Sheets ordered by gauge weight or thickness are subject to standard thickness and weight tolerances. A792 a792m 10 2015. It is divided into specified lengths of galvanized steel corrugated roofing sheet and galvanized steel coil.

Material bend radii and minimum bend size charts. Standard specification for steel sheet metallic coated by the hot dip process and prepainted by the coil coating process for exterior exposed building products.
