1 5 50mm thickness astm a588 corten steel plate

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.

This grade is designed for projects requiring atmospheric corrosion resistance longer than bare cold rolled steel. Unique combination of steel properties provides corrosion resistance superior to that of carbon steels with or without copper addition. When properly exposed to the atmosphere, A588 is suitable for many applications in the bare (unpainted) condition.

There are three types of A588 steel – Type A, Type B, and Type C, which represent different levels of corrosion resistance. ASTM A588 Type A is generally the most commonly used grade, which has good atmospheric corrosion resistance, and is suitable for many applications that are not in direct contact with the elements. ASTM A588 Type B has the same mechanical properties as Type A, but has improved atmospheric corrosion resistance. ASTM A588 Type C is a weathering steel which exhibits 50,000 minimum yield strength characteristic allows cost reduction through the ability to design lighter sections into structures.

A588 steel is available in a variety of forms, including sheet, coil, plate, and shapes, and is available in a range of thicknesses, ranging from 0.125 to 50mm. It is to be noted that the atmospheric corrosion resistance of A588 steel is better than that of carbon structural steel with or without copper addition. When properly exposed to the atmosphere, A588 is suitable for many applications in the bare (unpainted) condition.
