1. Cantilever cold roll forming machine. This equipment structure can limit the width of the forming strip to the length of the cantilever shaft. It is possible to press some products with thin profiles, or products with wide plate width and only one side of the profile. This method is not suitable for products with excessively pressed profiles, because only one side is stressed.

2. Double-ended cold roll forming machine. This structure is two cantilever installations and both sides of the strip, the width can be adjusted freely from inside to outside, and at the same time, products of any width can be formed within the limited width.

3. Through-axis double-end cold bending machine. The axial deflection of the through-shaft cold bending machine is smaller than that of the cantilever machine of the same specification. On this cold roll forming machine, the rolls are fixed on the racks on both sides.

4. Standard cold roll forming machine. This type of equipment is supported by bearings on both sides, and the bearings are fixed on the side plates.
