HSLA Steel Sheet A588
ASTM A588 is high-strength low-alloy structural steel, divided into 4 levels: A588GrA, A588GrB, A588GrC, and A588GrK. Steel plates are used in welded, riveted and bolted structures, but are primarily used in welded bridges and buildings where reduced weight or longer life is required. The atmospheric corrosion resistance of this steel is significantly better than that of copper-containing or copper-free carbon structural steel in most environments. When completely exposed to the atmosphere, this steel is suitable for many occasions in the exposed state, with limited materials. The thickness is no more than 200mm.

A588 high strength structural steel plate Products Details
A588 steel plate refers to high-strength, low-alloy structural steel plate that complies with ASTM A588 specifications. ASTM A588 is the standard specification for weathering steel, a type of steel with enhanced resistance to atmospheric corrosion.
A588 high tensile steel sheet are primarily used in outdoor applications where exposure to the elements and atmospheric conditions may cause corrosion. It is commonly used in buildings, bridges, buildings, towers and other structural applications.
A588's corrosion resistance is a result of elements such as copper, chromium, nickel and phosphorus. The addition of these alloying elements creates a protective oxide layer, called patina, that helps inhibit further corrosion.
