Products Description
PPGI pre painted galvanised steel roofing sheets are metal sheets that are pre-coated with paint and zinc. The zinc coating, also known as galvanizing, protects the steel from rust and corrosion. PPGI sheets are primarily used as roofing for industrial and commercial construction projects. They can also be used for wall panels, door frames, and appliance housings. PPGI sheets have the corrosion resistance of galvanized steel, but they also have a customizable appearance. Pre-painted steel is also less expensive than aluminum and is more resistant to corrosion and wear. The steel thus produced in this process is a pre-painted, prefinished and ready for further processing into finished products or components.
PPGI pre painted galvanised steel roofing sheets zinc coated steel substrate for PPGI is typically produced on a continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating.

Products features
1. Excellent corrosion resistance and long service life: Due to the double protection of zinc and aluminum, the corrosion resistance of aluminized zinc coating is three times higher than that of pure zinc coating. When the zinc is worn off, the aluminum forms a dense layer of aluminum oxide, preventing further corrosion of the base metal. So it has a longer service life than galvanized steel.
2. Attractive appearance: Galvanized steel is silvery white. It has a gorgeous finish and a smooth surface. It has a more uniform shine compared to galvanized steel. That is why it is highly preferred as a building material or decorative panel.
3. Good heat resistance and heat reflectivity: This Al-Zn coating has good heat resistance. It can be used for a long time under high temperatures of up to 315 degrees without discoloration. In addition, its heat reflectivity is almost twice that of galvanized steel, greater than 0.70. Therefore, it is ideal for roofing solutions.
4. Good adhesion: Due to its good adhesion, GL steel can be painted directly without any pretreatment and weathering. It is widely used as a base material for color coated steel. In addition, it has good workability, which means it can be easily processed, such as bending, stamping, etc.
