A588 Grade B Gold High Strength Steel Plate

A588 Grade B implementation standard: implement ASTM, ASME American Society for Testing and Materials standards.

A588 series of high weathering bridge structural steel plates include A588GrA, A588GrB, 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.

A588GrB, A588GrA, A588GrC manufacturing plants, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various types of cranes for mining and various engineering construction , Coal mine hydraulic support and other mechanical equipment and other structural parts.
