ASTM A653
Full Name
ASTM A653 – Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process
Scope
ASTM A653 is a standard specification for steel sheet that is coated with either zinc or a zinc-iron alloy using the hot-dip process. These coatings provide corrosion protection for the steel, enhancing its durability and lifespan.
Key requirements:
- Steel base: specifies the type of steel used as the base material for the coating.
- Coating type: defines whether the coating is zinc-only or a zinc-iron 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 A653 steel sheet is widely used in various construction and industrial applications, including:
- Roofing
- Siding
- Ductwork
- Structural components
- Automotive parts
