ASTM A588 Grade B/A588 Gr.B weatherproof steel plate, as a new generation of advanced steel material, has 2~5 times higher atmospheric corrosion resistance than ordinary carbon steel. And the longer its application time is, the more prominent corrosion resistance it have. ASTM A588 Grade B/A588 Gr.B weatherproof steel plates can be applied to the steel structures, such as buildings, vehicles, bridges, towers, etc., and can also be used in the manufacture of containers, railway vehicles, oil derrick, seaport, seaport, and oil flat platforms, for the features of corrosion resistance, free coating, thinning and consumption reduction and energy saving.
