Cold Rolling Steel

How We Cold Roll Steel Beams

Cold rolling is a metalworking process that is used to increase the strength and hardness of metal, such as copper or steel. A metal sheet or bar is passed through rollers at a controlled weight well under its recrystallization temperature, which is usually at room temperature. Although the cold rolling process increases the metal's strength and hardness it will also decrease its ductility, which will result in a metal that is more prone to cracks and fractures.

The cold rolling process

There are four main processes when it comes to cold rolling. The first process is Skin-rolling, where the metal will be reduced in size by .5 to 1 percent. This process will result in a smooth sheet that is more ductile than the other processes.

The next three cold rolling processes, Quarter Hard, Half Hard and Full Hard, can reduce a metal up to 50 percent in size, which will increase the strength and hardness of the metal. Each process has a different outcome. Metal cold rolled with the Quarter Hard process can be bent or rolled on to itself without fracturing. However metal cold rolled with the Half Hard process can only be bent to 90 degrees, and the cold rolled metal with the Full Hard process can only be bent to 45 degrees.

Cold Rolling Applications

Cold rolled metal can be made into sheet metal, strip metal, bars, beams and rods and are typically smaller than the same metal products that are produced through hot rolling or induction-bending.
