ASTM A572 Steel Angle - 50ksi Yield Strength

ASTM A572 steel angle is another high-strength, low-alloy (HSLA) columbium-vanadium steel sections. Owing to small amount of columbium & vanadium alloy elements, hot rolled A572 steel angle has better properties than carbon steel A36. First, A572 has higher strength than A36 like in yield strength and tensile strength. Second, it is easy to weld, form and machine.

Galvanized & Pre-lacquered steel angles
A572 steel angle has extensive applications due to high ratio of strength to weight. Because it doesn't contain copper content which is helpful in corrosive resistance, A572 structural steel angles are often hot-dip galvanized or pre-lacquered. The color for painting is on your request.
