Q
How do you control the during the polishing process?
A

After high standard requirements on polishing process,we can meet the requirements of electroplating,fine polishing and other application as the result of good smoothness and brightness of our tubes without any pitting,sand hole.

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)On the other hand, we use the gunny bags to protect the tube's surface when the tube laying-out.
