PPGI stands for Pre-Painted Galvanized Iron, commonly known as color-coated galvanized steel. A PPGI sandwich panel consists of two layers of color-coated steel plates with a core material in between. The color-coated steel panel, a type of PPGI sandwich panel, uses galvanized or cold-rolled steel as the base, with various decorative layers coated on the surface, including a cold-rolled layer, galvanized layer, and chemical conversion layer. The panel surface is not only vibrant in color and strong in adhesion but also highly machinable, allowing for shearing, bending, drilling, and other processes.

Features
1 Lightweight: 10-14 kg/m², which is about 1/30 the weight of a brick wall.
2. Thermal Insulation: Core material thermal conductivity is λ ≤ 0.041 W/m·K.
3. High Strength: The PPGI sandwich panel serves as a load-bearing plate for ceiling enclosures, resisting bending and compression, allowing many houses to forgo beams and columns.
4. Bright Color: No surface decoration is needed, and the anti-corrosion layer retains effectiveness for 10-15 years.
5. Flexible and Fast Installation: All construction is dry and unaffected by seasonal weather, allowing a construction period reduction of over 40%.
6. Environmental Protection: PPGI sandwich panels are recyclable and truly green, with no pollution.
7. Energy Saving: These high-efficiency walls offer excellent thermal and sound insulation, achieving energy savings of up to 50%.
Application Scenario
Construction Field: PPGI sandwich panels are widely used for exterior walls, indoor partitions, roofs, and ceilings, enhancing both safety and aesthetics in buildings.
Vehicle Field: These panels are extensively utilized in automobile manufacturing, including car bodies, door panels, and floor panels, improving both the safety and aesthetics of vehicles.
