The cold roll forming process begins with a flat metal strip, usually made of materials like steel, aluminum, or copper, which is fed through a series of rollers. These rollers are precisely engineered to bend and shape the metal gradually as it passes through the forming stands. Unlike traditional methods that involve cutting and welding, cold roll forming maintains the integrity of the metal, resulting in strong, durable profiles.
