High Strength Weathering Steel Angles. ASTM A588 and A709-50W corrosion-resistant and high-strength steel angles are available in the various sizes listed. A588 is considered the ASTM equivalent for Cor-Ten angles;

ASTM A588 is a kind of HSLA steel (high-strength, low-alloy) covering small amount of alloy elements – copper, chromium & nickel. These alloy elements effectively improve A588 properties and enlarge its applications. First, alloy composition adds its yield point strength to 50ksi and tensile strength to 70ksi. Second, with copper content, A588 has good atmosphere corrosive resistance and work for a longer time. Give its excellent comprehensive properties, A588 steel angle iron is extensively used in bridge, building and other structural applications.
