Some machines named roll-forming machines are rolling steel coil and step by step forming steel and finally, cut it as need size. For installation rolling shutter machine, you need about 15meter length and 5-meter width, also 3 phase power. Roll Forming Machine for making Rolling Shutter Strips are 2 types: • Gearbox rolling shutter machine.
They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction.
Hot rolled steel means that the steel has been roll pressed at temperatures over 1,700F. When the metal is so hot, it's easier to work with because it's more malleable. Steel mills start with a large mass of metal called a billet, which looks like a fairly long beam of metal.
