Steel angle bar is a hot rolled, mild steel angle shape with inside radius corners that is ideal for all structural applications, general fabrication and repairs. Steel Angle is used in industrial maintenance, agricultural implements, transportation equipment, etc. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its re-crystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its re-crystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes.
