A588 Gr.B, A588 Gr.A, A588 Gr.C manufacturing plants are used for general construction and various construction machinery.
ASTM A588 is a high strength low-alloy structural steel specification with higher strength and improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars.
Such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators for mining and various engineering construction , Loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.

8mm～200mm thick A588 series high weathering bridge structural steel plates include A588 Gr.A, A588 Gr.B, etc.
This type of steel forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so that it has high atmospheric corrosion resistance. This type of steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts, etc.
