ASTM A588 Grade A Weathering Steel Plate is an American standard weathering steel plate, also known as atmospheric corrosion resistant steel. Its material standard follows ASTM A588/A588M.
It can form a stable oxide layer (rust layer) in the atmospheric environment, which can effectively prevent further corrosion of steel.
The rust layer not only slows down the corrosion rate of steel, but also provides additional protection for steel, thereby reducing maintenance costs and cycles.
ASTM A588 Grade A Weathering Steel Plate is an excellent weathering steel that provides reliable structural and aesthetic solutions in a variety of harsh environments. It is an ideal choice for many engineering and decorative applications that require oxidation resistance and long-term weathering performance.
