Standard Specification for Steel Sheet, 55 % Aluminum-Zinc Alloy-Coated by the Hot-Dip Process
STANDARD published on 1.10.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers 55% aluminum-zinc alloy-coated steel sheets in coils and cut lengths for applications requiring corrosion resistance or heat resistance or both. The material is available in several designations: commercial steel, forming steel, drawing steel, high temperature steel, and structural steel. Heat analysis shall be performed wherein the steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, aluminum, copper, nickel, chromium, molybdenum, vanadium, columbium, titanium, nitrogen and boron. Mechanical tests shall be performed wherein the steel sheets shall conform to the required values of yield strength, tensile strength and elongation. Triple-spot tests and single-spot tests shall also be performed and the materials shall conform to the required values of coating weight/mass. Steel specimens shall also undergo coating bend tests and shall conform to the required ratio of the inside bend diameter to thickness.
