DIN Cold Rolled and Internally, Externally Galvanized Steel Tube with High Precision

Synopsis of Process Routing：DIN highly accurate, cold rolled and bright seamless steel tube is used as the tube to be galvanized. The inner and outer walls of tube are electroplated, and/or passivated with military green after galvanizing. The caps are used to cover two ends of tube to prevent from the dust.
Main Features：white galvanized, color galvanized (yellow galvanized) and passivation with military green. The high brightness on the surfaces of inner and outer walls is obtained after galvanizing. A good property of antirust and anticorrosion on inner and outer walls of tube are achieved.
Main Application：High anti-corrosive performance, Salt spray testing as per GB/T10125, Testing times for 240 hours without rusting.
