The polyurethane sandwich panel is a two-layer high-quality color-coated steel plate or some other precision-formed metal sheet as the surface material. After roll forming, the flame-retardant polyurethane foam liquid is injected into the middle, and then foamed and cured at high pressure. Under the conditions of specific production process and technical conditions, the strong adhesion with metal panels and the composite design have become beautiful, flat, rigid and tough building structural panels. It has the characteristics of fire prevention, heat preservation, waterproof and sound insulation in China, which can bring more high-quality appearance and good effects to the building. architectural plank.
Features of roof panels: Polyurethane roof panels are connected by dark nails, the panel surface is closely lapped, and there are waterproof grooves, which can effectively prevent water leakage, so the waterproof performance is excellent, and the occurrence of cold bridges is avoided at the same time. The 40mm peak height increases the load-bearing capacity of the roof panel. While ensuring the thermal insulation effect of the building, it can effectively save construction costs, and the minimum surface slope can reach 3%.
Wall panel features: Polyurethane wall panel data has developed a variety of product design effects (small corrugated, flat, embossed, embossed) for users to choose from, and is the latest building exterior wall panel. Polyurethane wall panels are blind-nailed with no exposed screws, giving the building an elegant look. Polyurethane wallboard has high bending resistance, which enables the wall to have better mechanical properties and thermal insulation properties, reducing the need for auxiliary steel structures.
