5.What��s electrostatic powder coating��

   The technique is to ultilize electrostatic spray equipment to spray powder coating on the surface of the shaped product. Under the electrostatic effect, the powder will be absorbed evenly on the product surface, forming a powder coating. By baking in the high temperature, the powder coating turn into the final coating for different usage. The spray machine is better than spray paint in aspects of machine strength, adhesion, carrasion resistance, anti-aging process, etc..

6.How many surface processing techniques in Grass Company��

   The main technique using in producting steel bin and bench is electrostatics powder coating, because this kind of finished goods are vivid, enduring and affordable. In the recent years, our exports with hot dip galvanizing in liquid or in powder surface. This advanced technology has greatly enhanced anti-corrosion, but the cost is relatively higher
