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. ASTM A 588 Gr.B steel with the thickness form 8mm~200mm is used as high weathering bridge structural steel.
ASTM A 588 Gr.B steel Application:
ASTM A588 Grade B Corten steel widely used in air preheater, economizer, railway carriage, containers production, bridge building , construction and so on.
