Round-cornered squares are mainly used in forging steel parts. Typically, our high-strength carbon and alloy-steel bars are custom-formulated for specific applications in heavy-construction equipment, automobiles and trucks, agricultural equipment, mining, and marine drive systems.
Rolling Mill No. 1
• 3" to 8" round-cornered squares
• Round-cornered squares will be available in most 1/4" increments and are subject to accumulation.
Intermediate and metric sizes can be produced provided certain minimum quantities are met. Please inquire.
