Precision Steel Tube

Precision Steel Tube are produced by Cold Drawn and Cold Rolling, with very good OD and ID tolerance and smoothness ,

with very good Concentricity, Good Ovality, Good Roundess, Less Deviation, suitable for machinery and CNC machining part, for auto parts.

Cold Drawn Seamless tubing (also known as CDS Steel Tube. Cold Drawn Seamless tubes offer tight tolerances compared to Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing.

CDW Steel Tubes  is made by drawing the ERW tubes from the tube mills through a plug and die combination, mounted on the draw bench. The end tagged and annealed tubes are drawn through a closely machined die that controls the outside diameter of the tubes. At the same time the tube passes over a plug that controls the inside diameter. Further, the manufactured tubes are processed by the downstream facilities for different industry applications.
