A588 Alloy Structural Steel Plate

A588 Alloy Structural Steel Plate Description

A588 alloy structural steel plate not only has high weather resistance to resist atmospheric corrosion, but also has good mechanical properties. As a matter of fact, this steel plate can form a protective layer on the surface of the metal substrate through alloying of Cu, P, Cr, Ni, etc., thus having high atmospheric corrosion resistance. The steel plate has high tensile strength and yield strength at room temperature, and has good elongation properties. The steel plates are widely used in structural engineering fields such as bridges, high-rise buildings, towers, and transmission towers. Its weather resistance can provide long-term structural stability and strong resistance to atmospheric corrosion, thus extending the service life of the structure.
