SOLAR ENERGY STAND STRUCTURE TUBE

Model LW 40x40-150x150 DFT square tube/pipe mill are mainly applicable to the solar energy  tube rack .
the main tube specification is 40x40mm to 150x150mm, Most of structural tube use high anti-corrosion Zn-Al-Mg material.

DFT TECHNOLOGY ADVANTAGE:

1.Reduce tube surface scratching: tube surface is less scratch than technology of round into square, forming well-shaped.

2." R" angle is more straight .

3.In the process of forming square tube,the roll adopts the combine roll ,one set of rolls can cover most of the welded pipe size without changing roll,the roll sharing rate reach 80%.
