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.

A572 steel plate refers to a high-strength low-alloy (HSLA) steel plate that conforms to the ASTM A572 specification. The ASTM A572 specification covers A572 Grade 42, A572 Grade 50, A572 Grade 55, A572 Grade 60, and Grade 65.

A572 steel plates are designed to have higher strength and improved notch toughness compared to carbon steels. They are used in structural applications where weight savings, higher strength, and durability are required.

A572 steel plates are commonly used in construction and structural engineering applications. They are utilized in buildings, bridges, infrastructure, heavy machinery, transmission towers, offshore structures, and more.
