What are your main raw material suppliers?

We never use recycled material to make tubes, only the first class material.

 All of the raw materials of Vinmay are from high quality suppliers such as BAOSTEEL,TISCO,TSINGSHAN,ad so on,so that we can make sure the stability and rust corrosion resistance of our products. The thickness tolerance of coil could be controlled within +/-0.02-0.03mm.


All the raw material of Vinmay will  go through the strictly inspection including machenical propertity, chemical position and so on. We can provide the formal MTC report together with our goods.
