Great Roll Formed Part: noun, a part whose material, tolerances, and design are executed effectively, on schedule, and at an acceptable cost. A Great Roll Formed Part can easily become part of a reliable supply system.
Unlike traditional metal sheet fabrication methods, like cold roll forming, there are particularity, complexity and diversity on the stamping technology of aluminum alloy plate.
Roll forming, also spelled rollforming, is a continuous bending operation in which a long strip of metal sheet (usually steel coils, like PPGI, GI, PPGA, Aluminum etc) passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
Metal fabricators and other manufacturers have long dismissed rollforming. Steep upfront costs, high-volume production requirements and absence from collegiate engineering curricula have made the process foreign at best, and cost-prohibitive at worst.
