A588 steel plate is a corrosion-resistant steel high-strength low-alloy (HSLA) structural steel plate that is excellent for welding, riveting or bolting in construction applications, primarily welded bridges and buildings where savings in weight or added durability are important. When properly exposed to the atmosphere, A588 is suitable for many applications in the bare or unpainted condition.
