Structural, Carbon &
HSLA Steel Plate
ASTM A572

A high-strength low-alloy steel plate that is utilized in a variety of structural applications. This specification is produced in Grades 42, 50, 55, 60 & 65, the grades representing the yield strength. Plates that are 4” and thicker are made to a 42 KSI yield, although material can be modified to reach the 50 KSI min yield.
