ASTM A924
Full Name
ASTM A924 – Standard Specification for General Requirements for Steel Sheet, Metallic-Coated by the Hot-Dip Process
Scope
ASTM A924 is a standard specification for steel sheet that is coated with a metallic coating using the hot-dip process. This coating provides corrosion protection and other beneficial properties to the steel.
Key requirements:
- Steel base: specifies the type of steel used as the base material for the coating.
- Metallic coating: defines the specific type of metal used for the coating, such as zinc, aluminum, or a zinc-aluminum 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 A924 metallic-coated steel sheet is used in various construction and industrial applications, including:
- Roofing
- Siding
- Ductwork
- Structural components
- Automotive parts
