A572 Steel Plate
A572 Steel General Information
The ASTM A572 carbon steel specification covers the standard requirements for Grades 42, 50, 55, 60, and 65 for high-strength low-alloy columbium-vanadium structural steel shapes, plates and bars for applications in bolted, riveted and welded structures in bridges and buildings. The combined use of columbium, vanadium, titanium meet the requirements of the producers and A572 specifications.
A572 most common grade is Gr. 42. PGI also carries A572 Gr. 50. A more difficult to find Gr. 65 steel plate is also available.
Common Uses of A572 Steel Plate
Common uses of A572: Gusset plates, bridge plates, bearing plates, construction equipment, transmission towers, machine frames and pedestals, base plates, machine mounting plates, etc.
