ASTM A588 steel includes Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.

Scope of application
ASTM A588 steel is known for its weather resistance. When exposed to external conditions, its corrosion resistance becomes stronger even if it is not painted. ASTM A588 steel has four times the corrosion resistance of carbon steel. The application of ASTM A588 steel is very wide. In addition to its typical application in welded bridges and buildings, this specification is also widely used in railway passenger cars; including transmission towers and telephone towers, trucks, bridges and gusset plates, and housing shells. ASTM A588 steel also maintains a good strength-to-weight ratio, meeting the high strength requirements of carbon steel with less weight.
