Q:How do you control the quality during the polishing  process?

A:1)As for the mirror polish square/rectangular tube , we will polish it as least four times)

2)During the polishing processing, we set a special sanding wheel to polish the welding part.

3)To avoid scratches,after polishing,the tubes will be lay out on a steel crate then we could lift the whole steel crate instead of the tube.

4)Then, we have quality control  department  to check product .

5)After all steps, we use the gunny bags to protect the tube's surface when the tube laying-out.
