Roll forming is a manufacturing process that shapes metal into long, continuous profiles. It involves feeding a flat strip of metal through a series of rollers, which gradually bend the material into the desired shape. This method is efficient for producing uniform cross-sectional shapes, such as channels, angles, and other structural components. The process is commonly used in industries like construction and automotive, where strong and lightweight materials are needed. Roll forming can be applied to various metals, including steel and aluminum, making it a versatile choice for creating parts that require precision and durability.
