In Metal Furniture industry, there are three finish for metal furniture, that is water electric plating finish ,  powder coated ( powder coated can be normal powder coated or outdoor powder coated )and PVD coating finish .

Here video for PVD coating finish for reference

 

 

PVD technology is a surface treatment process that uses sputtering, evaporation or ion plating techniques to form a thin film on a substrate using titanium, gold, graphite, crystal and other metal or non-metal, gas and other materials in a vacuum. The methods frequently used mainly include: evaporation coating and sputtering coating, collectively referred to as physical vapor deposition (Physical Vapor Deposition), which is PVD. The usual “IP” (ion plating) ion plating is because various gas ions and metal ions participate in the film formation process and play an important role in the PVD technology. In order to emphasize the role of ions, they are collectively referred to as ion plating. Compared with traditional chemical coating methods, PVD has many advantages: such as no pollution to the environment, it is environmentally friendly process; it is not harmful to the operator; the film is firm, dense, strong in corrosion resistance, and uniform in film thickness.

With the increasing popularity of colored stainless steel tubes, stainless steel materials are usually made of PVD materials, the colors can be customized, and there are many types of colors that can be plated, and the colors are bright and durable.
