Special of GL180 Series:
The particularity of case and plating. Case is made of brass, the opening port is made of high quality alloy. Both of them are polished by hand carefully and with double plating: PVD-Zirconium plating based on Chromium plating. PVD –zirconium Plating: (PVD = Physical Vapor Deposition). Firstly, a Chrome plating is plated on the polished brass or alloy surface, then a Zirconium Coating is plated over the Chrome plating by the PVD technology. Zirconium is a metal which has high hardness, high melting point and high Corrosion-resistance, this new plating bring the best corrosion-resistance to the product, and makes it never tarnish or discolor. The surface of Zirconium Coating has the color of polished brass and nobler shine like silk.
