Coating | Rustproof Structure | ||||||
1st layer | Metalic zine layer | The steel/iron substrate is protected from corrosion by the
self-sacrificial galvanic effect of zinc coating. | |||||
2nd layer | Chemical conversion coating layer | Rustproof performance is improved, as the chemical conversion
inactivates the zinc plated surface and attributes to tight
adhesion between chemically converted layer and paint-layer | |||||
3rd layer | Baked ceramic surface coating layer | Instrusion of corrosive factors are intercepted by the strong paint
film made of ceramic materials. | |||||

High corrosion resistance | Salt spray test for more than 2000 hours |
No hydrogen brittleness | The base material is stainless steel, the treatment process has no
pickling, millisecond. Risk of hydrogen embrittlement |
Environmental protection | Do not contain harmful substances, such as chromic acid, lead,
cadmium. |
Subzero treatment | Low temperature 200℃ process will not result in a material change |
Drug resistance | Alkali resistance, uv resistance, strong acid rain. |
Weather resistance | -60℃-550℃ |
