Square tube |
Material：GBT6728/ASTM A500
|
The hot finished hollow sections-square,rectangular and circular,have constant external dimension within the same serial size,and only the thickness is increasing.in other words,the same column size can be maintained throughout the full height of the building,only changing the thickness,simplifying architectural details and ensuring economy in fabrication.
|
We can manufacture square pipe, rectangular pipe,rotary casting seamless pipe,large diameter welded pipe(welding line can be planished and fault localization. |
