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
