32 Facts About Roll Forming

What is Roll Forming?

Roll forming is a continuous bending operation where a long strip of metal, usually coiled steel, is passed through consecutive sets of rolls at room temperature. Each set of rolls performs only an incremental part of the bend, until the desired cross-section profile is obtained. This process is highly efficient and versatile.

1. Roll forming can produce complex cross-sections that are impossible to achieve with other metalworking processes.
2. The process is highly efficient, capable of producing parts at speeds of up to 100 feet per minute.
3. Roll forming can handle a variety of metals, including steel, aluminum, copper, and brass.
4. The process is ideal for high-volume production runs due to its speed and efficiency.
5. Roll forming minimizes material waste, making it an environmentally friendly option.
