Structural, Carbon & HSLA Steel Plate

A588 / A606 / A242
A588 is a high-strength low-alloy steel plate used in structural applications such as bridges and buildings. Its advantage over A572 50 is its “weathering” ability, which provides atmospheric corrosion resistance and ultimately longer life in applications where exposure to elements will be a factor. We generally stock this material as A588 Gr A & B in plate and 606 in sheet.
