A roll former is a machine used in manufacturing to create metal products with specific shapes and profiles. It works by feeding a flat strip of metal through a series of rollers that gradually shape the material into the desired form. This process is efficient for producing long lengths of uniform products, such as metal roofing, siding, and structural components. The roll forming process is highly versatile and can accommodate various materials, including steel, aluminum, and copper. It is commonly used in industries like construction and automotive, where precision and consistency are essential. The resulting products are often lightweight yet strong, making them ideal for a wide range of applications.
