A588 Carbon Steel Coil
ASTM A588 steel is sorted into Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.
Description
A588 Carbon Steel Coil Description
A588 carbon steel coil shows good corrosion resistance after a special treatment. It is resistant to corrosion of the atmosphere, sea water, and salt spray, thus extending its service life. For another, A588 carbon steel coil is made of high-strength steel that has high yield strength and tensile strength, which can meet the requirements of various structural parts. The coil also has good welding performance, making it easy to weld and process, and therefore improving the efficiency of engineering installation. A588 carbon steel coils are suitable for various structural parts that require corrosion resistance and high strength.

Scope of Application
ASTM A588 steel is known for its weather resistance. When exposed to external conditions, its corrosion resistance becomes stronger even if it is not painted. ASTM A588 steel has four times the corrosion resistance of carbon steel. The application of ASTM A588 steel is very wide. In addition to its typical application in welded bridges and buildings, this specification is also widely used in railway passenger cars; including transmission towers and telephone towers, trucks, bridges and gusset plates, and housing shells. ASTM A588 steel also maintains a good strength-to-weight ratio, meeting the high strength requirements of carbon steel with less weight.
