PPGI Coil PPGL steel coils dx51d color coated steel prepainted steel coil
| What is Prepainted Steel? |
Color Prepainted Galvanized PPGI Steel Coils is a product made of cold rolled steel plate and galvanized steel plate by surface pretreatment (degreasing, cleaning, chemical conversion), continuous coating (roll coating), baking and cooling. Coated steel sheet has light weight, beautiful appearance, good corrosion resistance and can be processed directly. It provides a new raw material for construction, shipbuilding, vehicle manufacturing, household electrical appliances, electrical industry, etc. It has played a good role in replacing wood with steel, efficient construction, energy saving, pollution prevention and other good results

Color Prepainted Galvanized PPGI Steel Coils Poducing process
Prepainted Galvanized Steel Coil/PPGI coating film introduction
Top paint film:
RPE, SMP, HDP,PVDF,Other paints.
Function: It functions as a sunlight proof cover, especially prevent the destroy by the ultraviolet rays. When the top paint film reaches a certain thickness, it forms a compact cover, and reduce the water and oxygen permeability.
Primer paint film:
Polyurethane, Epoxy, PE
Function:Strengthen the adhesiveness between the top paint film and the basemetal. Even permeable water happens, the top paint film will not peel off. There is corrosion inhibitor which is corrosion resistance. Polyurethane is necessary for higher processing flexibility and weather resistance requirements.
Passivation layer
Function:Increase the adhesion between the metallic layer and coating film. Extend life span also.
Metallic coating
Function:The metallic coating provides the fundamental protection for the steel.
The popular coating metal are galvanize, galvalume and other alloyed metals.
Substrate steel
Cold rolled steel is usually used as substrate, it decides the mechanical properties and the steel shape and flatness.
Back paint film
Epoxy, Modified PE.
Back paint can sustain color in good condition and has good binding.
