Product Details
The structure of PU sandwich roof panel with 3 ribs is mainly composed of three layers: the inner and outer layers are metal panels (such as steel plates, aluminum plates, etc., the specific materials may vary depending on the manufacturer and product), and the middle sandwich layer is hard polyurethane foam. This structure is compounded by a special process under high pressure, which makes the sandwich panel have extremely high strength and stability.
Characteristics of PU sandwich roof panel with 3 ribs
- High-efficiency thermal insulation: polyurethane foam as a sandwich layer has an extremely low thermal conductivity, which makes the 3-flute PU sandwich roof panel have excellent thermal insulation performance.
- Good fire resistance: PU sandwich panels have a high fire resistance level, meet national safety standards, and can reduce fire risks to a certain extent.
- Waterproof and moisture-proof: Since the closed-cell rate of polyurethane foam is as high as 90%, the PU sandwich roof panel with 3 ribs has excellent waterproof and moisture-proof properties and is suitable for use in humid environments.
- Lightweight and high strength: Compared with traditional building materials, PU sandwich roof panels with 3 ribs are lighter, but have higher strength and hardness, can withstand larger loads, and are not easy to deform or damage.
- Corrosion resistance: PU sandwich panels have strong resistance to most acids and alkalis, and can maintain their stability in harsh environments.
- Convenient construction: 3-ribs PU sandwich roof panels are easy to cut, paste and fix, and the construction process is simple and fast, without the need for secondary decoration.
