factory directly sale ASTM A588 Weathering steel plate

ASTM A588 Steel plate is a high strength steel that offers all the advantages of A572 Gr. 50 but with excellent corrosion resistance to the elements. The elevated levels of copper in Steel plate ASTM A588 produces a self healing characteristic that produces a natural red oxide patina look.
