A572/S355JR Carbon Steel Bar Description
A572 steel bars are lightweight, but have good strength, ductility and workability, making them ideal for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.
Scope of Application
ASTM A572 carbon steel low-alloy steel is widely used as bridge panels, support plates, mechanical mounting plates, etc. for construction equipment, transmission towers, racks and other equipment.
