Synopsis of Process Routing: DIN highly accurate cold drawn bright seamless steel tube is used as the tube to be galvanized, the outer wall is electroplated, caps are covered at two ends of tube to prevent from the dust.

 

Main Features: Different color of zinc such as white, yellow, army-green, black is evenly distributed in the surface of the tube, good brightness and antirust and antisepsis could improve after zinc coated.

Applications:

Automotive,military,railway industry,with high requirement of the tube’s  brightness, cleanness,antirust,and antisepsis.
