These sheets are produced from rimming, capped, or semi-killed steel, and are intended for uses involving simple bending or moderate forming. They may be bent flat on themselves in any direction at room temperature without cracking. The zinc coating will withstand bending without flaking when tested in accordance with ASTM A 525. The coating is applied by the continuous hot-dip process, producing a tight coat of prime spelter of the 1.25 oz. per square foot coating class. Sheets meet the Commercial Quality requirements of ASTM A 526. Gauges 16 and lighter are available as Lock Forming Quality, conforming to ASTM A 527.
