PE protective film: prevent scratches and external contamination during transportation and construction
PVDF fluorine energy multi-layer composite film: improve the corrosion resistance of the surface of the galvanized sheet, protect the substrate and play a role in heat insulation
Polymer adhesive layer: polymer fission at a temperature of 15 ° C, bonding the upper and lower layers
Chemical treatment layer: Improve the corrosion resistance of the galvanized sheet coated substrate and the adhesion of the film
High-strength metal substrate: galvanized or galvanized steel sheet (0.2mm-0.8mm)
PVC/PET/nano film: improve the corrosion resistance of the back of the galvanized sheet
