ASTM A572 High Strength Steel I Beam

Hot rolled A572-50 steel I beam – tapered flanges.

ASTM A572-50 steel i beam - IPN dimension.

A572-50 steel i beam is widely used in construction & building applications for it can provide more strength per unit of weight. Its low content of alloy elements such as columbium & vanadium optimize the properties in strength and atmospheric corrosion. Owing to its high strength of 50,000 ksi yield strength, A572-50 steel I sections are increasingly replacing common carbon steel beam like A36 which should be thicker to satisfy the strength requirement.

ASTM 572 Steel I section is available in other grades like 42, 55 & 60. Please find the specific chemical components in the table below.
