Galvanized steel coil
3 year ago
The pre-painted galvanized steel coils are a product obtained by subjecting a hot-dipped galvanized steel sheet to a surface chemical treatment, applying organic coating on the surface, followed by baking and curing.
Coating thickness selection
The top coating is larger than 20μm to prevent the intrusion of corrosive media. Due to the different anti-corrosion mechanisms of primer and finish coating, not only the total coating thickness should be guaranteed, but also the thickness of primer (>5μm) and finish coating (>15μm).
PVDF pre-painted steel coil requires a thicker coating. It provides a longer service life. The requirements for the backside paint coating depend on the application, and the sandwich panel only requires a layer of primer. The formed steel plate requires two coats. The thickness is at least greater than 10 μm.
Protective Film
The protective film is a transparent or colored plastic film coated on the surface of the pre-painted galvanized steel coil. The purpose is to prevent scratches on the painted surface paint during cold roll forming. Our plastic film thickness is 30 microns, 40 microns, 50 microns, 60 microns, and 80 microns.
PPGI Coil Uses
The main uses of pre-painted galvanized steel coils (PPGI coils) are home appliances and construction.
Home appliance uses are mainly side door panels for refrigerators, and shells for air conditioners, freezers, and washing machines. The construction field is more widely used than home appliances.
PPGI coil for construction is used for roofing, guttering, sandwich panels, industrial building facades, cold storage panels, and rolling doors.
Z275, Z150, and Z100 can be used for the pre-painted steel coils. For less demanding environments use Z40 zinc and polyester coatings.
