PPGL is the abbreviation of pre-coated galvalume steel, which uses galvanized steel as the base material. After surface pretreatment (chemical degreasing, chemical conversion treatment), the surface is coated with one or several layers of paint, which is baked and solidified to become PPGL. During the production process of az 150g filmed PPGL roll, the surface of PPGL is covered with a layer of plastic film, which mainly plays a protective role to prevent scratches and extend the service life.
The color-coating production line is equipped with a laminating machine that sticks the plastic film on the surface of the color-coated roll before unwinding. It has excellent corrosion resistance and aesthetics and is mainly used in wall panels, metal roofs, sandwich panels, etc. in the construction industry. The surface of the color-coated galvanized steel coil presents a unique smooth, flat, and gorgeous starlight, and the basic color is silvery white. The special coating structure makes it have excellent corrosion resistance. The normal service life of color-coated galvanized coils can reach 25 years. It has a very good heat resistance and can be used in a high-temperature environment of 315°C. It has good adhesion between the coating and the paint film and has good processing performance. It can be punched, sheared, soldered, etc.; the surface conducts electricity very well.
Due to the addition of a layer of plastic film, the cost and price are higher. But better protection.
We can make paint films of 10-30 microns. The higher the paint film, the longer the color will last. Paint materials include PE, SMP, HDP, and PVDF.
