Are you clearer about color coated coil now ?


1.Color coated steel coil classification

 (1)According to the use of the based material:cold-rolled steel coil, hot-dip galvanized steel coil, hot-dip galvanized alloy steel coil, hot-dip galvanized-aluminum alloy steel coil,electro-galvanized alloy sheet coil,electro-galvanized steel coil, aluminium coil

 (2) According to the production technology.

  • Depending on the coating: roll coating, spray coating, shower coating, powder, film coating, printing.
  • According to the number of times of application: one coating one baking, double coating double baking, three coating and three baking
  • 3D design PPGI coil: wood, marble or sheepskin, cement mortar and so on. There are also surface flocking products.


 (3) According to the type of paint: PVC coating steel, PE coating, Acrylic coating, fluorocarbon layer coating, SMP coating

 (4)According to the coating performance: High weathering coated steel sheet, high-temperature resistant steel sheet, self-extinguishing steel sheet, sterilized steel sheet, non-stick snow (for roof) steel sheet, fingerprint-resistant steel sheet, self-lubricating steel sheet.


2.The use of color coated steel coil.
 Widely used in construction, transportation, home appliances, light industry and other fields.

3. Process flow
 (1)Production methods: coating type, laminating (film coating) type, printing and dyeing type.
 (2)PPGI Process Flow 4-Stage:

1).Entrance Stage;

2).Pretreatment Stage;

3).Roller Painting Stage;


4.Exit Stage
 ➀ Uncoil→Stitching→Compression Roller→ Puller→Inlet Looper: For Connecting the coils, In order to provide the steel sheet continuously and consistently
 ➁Alkli Degreasing→Cleaning→Passivation→Baking:For getting rid of the oil stain and metal fillings, and painting passivation solution, In order to improve the anti-  corrosion ability and adhesive ability to the primer paint
 ➂Primer&Back Coating→Baking→Finish Coating→Baking→Cooling: For adopting the roller coating techniques, baking and water&Air cooling to make the paint       adhere to the sheet firmly.
 ➃Outlet Looper→Cutting→coiling:For recoiling as requirement tons.
