A588GrA American Standard Weathering Steel Plate Performance Analysis

A588GrA is an American standard weathering steel plate, and it is also a high-strength low-alloy steel that is resistant to atmospheric corrosion in accordance with ASTMA 588/A588M-05.

8mm~200mm thick A588 series high weathering bridge structural steel plates include A588GrA, A588GrB, etc. A588GrA steel plate 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.
