ASTM A527
Full Name
ASTM A527 – Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) by the Hot-Dip Process, Lock-Forming Quality
Scope
ASTM A527 is a standard specification for zinc-coated steel sheet, also known as galvanized steel, specifically designed for lock-forming applications. This type of steel is produced by dipping the steel sheet into molten zinc, which forms a protective coating that resists corrosion.
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 into complex shapes without cracking or splitting.
- Lock-forming properties: defines specific requirements for the steel’s ability to be formed into lock-forming shapes.
Applications – ASTM A527 galvanized steel sheet is widely used in construction applications that require complex shapes, such as:
- Metal roofing
- Siding
- Ductwork
- Building components
