A588 Grade B weather steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness.

ASTM A 588 Gr.B steel contains Cu, P, Cr, Ni and other elements, these elements give the steel A588 Grade B a high resistance to the corrosion of atmosphere. A588 Grade B steel plates and sheets are applied mostly on weathering construction components and bridge structural parts.

ASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars. The A588 specification is intended primarily for use in welded bridges and other structures where savings in weight or added durability is important along with the longer life cycle due to its corrosion resistant properties.
