There are four treatment methods of the stainless steel surface, the polished, the matte, the brushed and colorful spaying. Due to the spraying of colorful painting so we could often see the exquisite colorful metal sculptures in urban properties. The colorful metal sculpture surface is fabricated with sprayed technology, which features excellent adhesion and impact resistance, presenting amazing effect and at the same time, let the stainless steel sculpture more corrosion-resistant and wear-resistant. Therefore, the sculpture has good anti-rust performance. Furthermore, the process is simple and environmentally friendly. These colorful metal sculptures greatly enrich our surrounding environment and give people a different sensory experience.

Actually, it is the thermal spraying made the surface colorful by spraying the surface of the stainless steel sculpture with the material liquid in molten state so that sculpture surface would form a complete covering layer. Furthermore, the heat sources commonly used in this technology are gas burning, electric heating, and lasers.

The second method is the high-tech nano spraying, which is the most cutting-edge high-tech spraying technology currently in the world. This technology uses special equipment and advanced materials spraying chemical particles on the surface of the stainless steel sculptures, presenting various colors and exhibits spectacular highlight effects. Nano-spraying has a wide range of uses and is a new surface treatment technology.

The spray coating on the surface of the stainless steel sculpture is attached by the collision and irregular deformation of spray particles with the pressure of compressed air, spraying distance, melting temperature, and so on. The smaller the sprayed particles, the denser the sprayed layer and the better the adhesion. The adhesion between the spray coating and the surface of the sculpture is an important property of the spray coating.
