A588 I Beam
ASTM A588 steel beam not only enjoys high tensile & yield strength but also exhibits good resistance against atmospheric corrosion for its small copper content. Given its high strength, it weighs less than A36 steel section without a reduction in strength. At the same time, it is the best material for outdoor applications and shows orange-brown surface.
