1 Surface pretreatment
  Before coating, we remove the adhesive or the build eyewinkers of the basic board, so as to increase the basic surface and coating adhesive to get the surface resistant the rust, we call it pretreatment.

    2 Mechanical pretreatment
   Before painting, we take the manual tools, motor tools or spray, spray granule, to eliminate the surface eyewinker.
    3 Chemical pretreatment
   Before painting, we take chemicals to eliminate the basic board eyewinkers or to change into film.
    4 Electrochemical pretreatment
   Before painting, we take the chemicals to eliminate the basic board eyewinkers or to form the film. 。
    5 Degreasing
