ASTM A792
Full Name
ASTM A792 – Standard Specification for Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot-Dip Process
Scope
ASTM A792 is a standard specification for steel sheet that is coated with a 55% aluminum-zinc alloy using the hot-dip process. This alloy coating provides superior corrosion resistance compared to traditional zinc-coated steel, making it suitable for applications exposed to harsh environments.
Key requirements:
- Steel base: specifies the type of steel used as the base material for the coating.
- Alloy composition: defines the specific composition of the 55% aluminum-zinc alloy.
- Coating weight: specifies the minimum coating weight per unit area.
- Surface finish: specifies the allowable surface imperfections.
- Mechanical properties: sets minimum requirements for tensile strength, yield strength, and elongation.
- Formability: specifies the ability of the steel to be formed without cracking or splitting.
Applications – ASTM A792 steel sheet is widely used in various construction and industrial applications, including:
- Roofing
- Siding
- Ductwork
- Structural components
- Automotive parts
