Features of PPGI roofing sheet：
High durability: The galvanized iron substrate combined with the coating provides excellent resistance to environmental erosion such as rain, sunlight and moisture.
Rich aesthetic options: A variety of colors, textures and surface treatment options are available to enhance the appearance of the building.
Lightweight design: Despite its high strength, PPGI roofing sheets are lightweight and easy to transport and install.
Corrosion resistance:The dual protection of the galvanized layer and the coating can effectively extend the service life.
Good thermal insulation performance:The special coating has the function of reflecting heat, helping to keep the interior cool and save energy.
Structure and composition:
PPGI roofing panels are composed of multiple layers of materials, each with a specific function:
Substrate: Usually made of galvanized iron (GI) or aluminum-zinc alloy steel (GL), providing core strength.
Pretreatment layer: Enhances the adhesion of the coating to the substrate and has certain anti-corrosion properties.
Primer coating: Provides a barrier between the substrate and the topcoat, further enhancing adhesion and protecting the substrate.
Topcoat: The outer layer, available in a variety of colors and finishes, has UV resistance and enhances aesthetics.
Back coating: A protective layer on the bottom surface of the roofing panel that increases moisture resistance and abrasion resistance.
Application:
PPGI Roofing Sheet can be used for houses, factories, large buildings, etc.
