Structural, Carbon & HSLA Steel Plate

ASTM A588

A high-strength, low-alloy steel plate utilized primarily in structural applications such as bridges and buildings. This grade is designed for projects requiring atmospheric corrosion resistance. Its advantage over A572 50 is its weathering ability. When properly exposed to the atmosphere, this steel plate can be utilized in its bare condition (unpainted). We stock this material as A588 Gr A & B in plate and 606 in sheet.
