ASME SA588/SA588M Corten Steel Coil

ASME SA588 Corten Steel Coil is a pressure vessel grade weathering steel coil produced in accordance with the ASME SA588/SA588M standard. This steel coil offers outstanding atmospheric corrosion resistance and is designed for high-strength structural and pressure applications in environments exposed to the weather.

Just like its ASTM counterpart (A588), SA588 forms a stable, rust-like patina on its surface that slows further corrosion, reducing the need for maintenance or painting. The ASME version is commonly used in industries such as oil & gas, bridges, boilers, and structural frameworks requiring code-compliant material.
