Cold-rolled steel plate, powder electrostatic spraying, welding and rust cleaning, powder coating after zinc washing and phosphating. Good adhesion and good adhesion. Surface treatment process: work washing → degreasing → washing → derusting → washing → surface adjustment → Phosphating→washing→baking→spraying→solidification→spraying products. It is mainly used for placement, documents, data, and various kinds of file items. However, despite the fact that the use of different places and the substantial requirements of the grade environment, metal cabinets have long been favored by factories, schools, military units, enterprises and public institutions, iron cabinets have, fire, corrosion and wear resistance, the surface powder is no Poison, odorless, EU ROHS standards, bright color, color can be optional.

The steel plate is fully degreased, cleaned with pure water, warmed by degreasing, phosphating, surface conditioning, and drying processes, making the product more resistant to rust and having a longer life. Sheet metal large-scale equipment, compound molds, special tool holders, and the product processing process does not fall. One-time punching of parts is completed, which has high precision and versatility. Welding part adopts high standard fusion welding, smooth and smooth surface adopts automatic spraying line, surface electrostatic powder spraying (combination of manual and automatic line spraying, uniform coating, strong adhesion) adopts international brands to meet EU ROHS standard The product is truly environmentally friendly and non-toxic.
