ASTM A591

Full Name

ASTM A591 – Standard Specification for Steel Sheet, Electrolytic Zinc-Coated, for Light Coating Mass Applications

Scope

ASTM A591 is a standard specification for steel sheet that is coated with zinc using an electrolytic process. This type of coating is typically used for applications where a lighter zinc coating is desired compared to hot-dip galvanized steel.

Key requirements:

  • Steel base: specifies the type of steel used as the base material for the zinc coating.
  • Zinc coating: defines the minimum zinc 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 A591 electrolytic zinc-coated steel sheet is used in various construction and industrial applications, including:

  • Automotive components
  • Appliances
  • Building materials
  • Sheet metal fabrication
