1-1/4 inch Hot Roll Steel Round Bar A36 is made of low carbon steel that is commonly found in most industries. Unlike cold rolled steel, Hot Rolled Steel A36 has a rougher surface and with galvanization, it can resist corrosion well. A36 offers good weldability, machinability, and can be heat treated to harden its surface.
