Roll forming is a high-speed method of bending coiled metal into a custom designed metal shape by passing a metal strip through a series of roll dies. The process produces a metal profile with a uniform cross section along its entire length.
A simple process ideal for even the most complex shapes
Cold rolling occurs with the metal below its re-crystallization temperature (usually at room temperature), which increases the strength via strain hardening up to 20%. It also improves the surface finish and holds tighter tolerances. Commonly cold-rolled products include sheets, strips, bars, and rods; these products are usually smaller than the same products that are hot rolled.
Roll forming is a reliable, proven approach to metal shaping that is ideal for modern applications. This process uses a continuous bending operation where long metal strips, typically coiled steel, are passed through consecutive sets of rolls at room temperature. Each set of rolls performs incremental parts of the bend to produce the desired cross-section profile. Unlike other metal shaping methods, the roll forming process is inherently flexible, allowing secondary processes to be integrated into a single production line. For even the most demanding requirements, roll forming increases efficiency while reducing operational and capital costs by eliminating unnecessary handling and equipment.
