Roll Forming is a process in which a strip of metal, usually in coil form,
is continuously passed though a series of roller dies and progressively formed to the desired shape.In many cases roll forming eliminates multiple stage production, sub-assembly and finishing operations.
Any number of subassmbly operation can be continuously combined in the roll forming operation.
- Roll formed materials generally have a strength advantage over competing processes
in structural rigidity applications. - Roll forming can achieve closer tolerances than are possible with most other competing processes.
- Uniformity throughout the part assures precision fit, simplifies production,
speeds assembly and minimizes rejects. - Cold roll formed shapes can offer superior surface finish.
- Sharp clean contours can be maintained.
- The absence of die marks on the material often eliminates the need for additional finishing.
- Almost unlimited length parts are possible. The only limitations on part length are
dictated by material handling and shipping capabilities. - Once the tooling is made, almost any length shape can be rolled economically.
- Many additional operations, such as punching, notching, welding and bending,
that otherwise would have been performed assecondary operations can be incorporated into the roll forming line, reducing handling and processing costs. - Pre-punching inline allows holes or slots that cannot be done as a secondary operation because
of their location or features of the part to be included in the shape
