Color Coated Steel Gi Gl Ppgi Ppgl Prepainted Galvanized Steel Coils
Description
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
Chromated paint is used for cleaning the surface of the cold-rolled coil.
After Chromated, the next is zinc coated. The coil becomes a galvalume steel coil now.
After zinc coated, the next is Chromated again, for cleaning the galvalume steel coil surface again.
The primer coating is used for increasing the adhesion of the top coating. When cold roll forms, the paint will not fall off.
The top paint coating metal is PE or PVD
