Roll forming is a manufacturing process used to create long metal parts with a constant cross-section. In this method, a metal strip is fed through a series of rollers that gradually shape it into the desired profile. The rollers are designed to bend and form the metal without cutting or welding, making it an efficient way to produce complex shapes. This technique is commonly used in industries such as construction and automotive, where components like metal roofing, window frames, and automotive parts are needed. Roll forming is valued for its ability to produce high volumes of consistent and precise parts quickly.
