Product Description
 

The processing of small diameter square tubes is generally to forming from round to square, that is, before the strip is welded, it is a round tube, and it is rolled into a square tube at the sizing part.

This equipment adopts the advanced direct square technology, which starts rolling into a square shape when the steel strip begins to forming. This advanced technology can help customers save at least 5% of the strip cost.

Direct square roll forming equipment does not need to change the tooling molds when producing square tubes and rectangular tubes of different sizes. The production of steel tubes of different sizes uses a set of molds. This item alone can help customers save at least 50% of the mold cost.

In addition, this technology can not only help customers save mold costs, but also can automatically adjust the mold by pressing a button when producing tubes of different sizes, saving customers at least 3 labor costs.

Direct square can produce square tubes with different diameters. The diameter range of the tube produced by this equipment is 100x100mm to 300x300mm.
