    Sheet metal processing products, because of its material for the metal sheet, in addition to stainless steel, most of the material is the need for anti-corrosion anti-rust oxidation
     1. Sheet metal processing industry commonly used materials are: SUS stainless steel, SECC electrolytic plate, SGCC galvanized sheet, SPCC cold-rolled plate, SPHC hot-rolled plate, AL aluminum, SPTE tin, in addition to stainless steel other materials are generally required anti- Oxidation.
     2.SUS stainless steel corrosion: passivation treatment
     3.SECC electrolytic plate, SGCC galvanized sheet, SPTE tinplate three kinds of materials products, because the material itself is not easy to rust on the surface of the coating, but the cutting surface is extremely easy, anti-corrosion method: A. cutting surface coated silver paint; B (Anti - rust agent for a fast and volatile anti - rust chemical reagents, will not hurt the product appearance and performance), the use of anti - rust,
     4.SPCC cold-rolled plate, SPHC hot-rolled plate anti-corrosion method: A. plating; B paint; C spray
     5.Al aluminum plate of the anti-corrosion method: A. Anodizing; B. Baking paint; C. Spraying
