Description
The prepainted steel coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, and galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating), followed by baking and curing.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 resultsThe total thickness of the pre-panted galvanized steel coil is composed of the base steel - coating -primer - top paint - protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the basesteel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.Usually, the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print,camouflage, brick.| Product Name | PPGI, Prepainted Galvanized Steel Coil,Carbon Steel Coil,Galvalume |
