A steel roll forming machine is a mechanical device used to shape steel into various shapes by passing it through a set of rollers. It is commonly used to create metal roofing sheets, wall panels, and other structural components. The machine first feeds the steel coil into the machine, passing it through a series of rollers that gradually shape it into the desired form. The rollers are typically designed with grooves or dies that help to shape the steel. The final product is then cut to the desired length and shape. Steel roll forming machines are commonly used in the construction, automotive, and manufacturing industries.
