Stock lengths for ASTM A588 squares is 240". We can cut to lengths if required.
See graph below for available sizes.
ASTM A588 covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition.
When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition.
ASTM A588 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength
Corten squares do not arrive pre-rusted. Weathering steel will rust naturally when exposed to the weather.
