ASTM A572 Steel Plate

ASTM A572 Carbon Steel Plate

ASTM A572 Specification refers to High-Strength Low-Alloy Steel Plate for structural building, among the 5 steel grades of 42, 50, 55, 60 and 65, Grade 50 is one most common steel in applications where need more strength and less weight, use steel plate of this grade other than ordinary carbon steel will make the steel structure with same steel strength but lighter weight.

ASTM A572 Gr 50 steel material can be bended or shaped by cold work, also has increased resistance to atmospheric corrosion, which is good to increase steel structure service life. If you are interested in buying ASTM A572 Grade 50 steel plate, please contact us now for the latest price now.
