China roll forming machine is a metal working process that involves passing a long strip of sheet metal through consecutive sets of rollers to bend and shape the material into a desired cross-section profile. Roll forming machines are widely used for producing metal structural components with constant cross-sections such as roofing panels, wall panels, door panels, railing systems, automotive components, appliance housings, and many other industrial and consumer products.
China has become a major manufacturer and supplier of roll forming machines and equipment over the past few decades. The rapid growth of China’s construction, infrastructure, automotive, appliance, and other manufacturing industries has greatly expanded the domestic market demand for all types of metal forming machinery including roll forming. At the same time, rising labor and production costs in developed countries have motivated many international manufacturers to shift production to China. This has stimulated further development of the Chinese roll forming machine industry.
