PU Edge Sandwich Panel

Utilizing the physical properties and unique formula of polyurethane (PU.PIR), the polyurethane foaming agent is evenly sprayed on the color-coated steel plates, so that the foaming agent is foamed between the color-coated steel plates to form three layers of one-time molded polyurethane (PU,PIR) color steel composite sandwich panel. This new lightweight building material is a perfect combination of color-coated steel plates and polyurethane. The PU edge sandwich panel is the development direction of lightweight building materials.

1. Aesthetic performance: The interface of the PU edge sandwich panel is designed according to European standards. The appearance is round and smooth, the panel surface is smooth and beautiful, the joints are tight, and the strength is reliable, effectively preventing the occurrence of hot and cold bridges.

2. Good stiffness: The polyurethane double-sided sealing rock wool core material and two layers of steel plates are bonded into a whole and work together. The PU edge sandwich panel overall stiffness is much better than ordinary profiled composite plates. After the sandwich panels are fixed to the purlins through connectors, the overall stiffness of the roof is greatly improved and the overall working performance of the roof is enhanced. By using rock wool sandwich panels, a larger span can be used, so the purlin consumption can be saved by 1/3 to 2/3.

3. Anti-scratch protection: During the production of PU edge sandwich panel, a polyethylene self-adhesive protective film can be pasted on the surface to prevent the surface coating of the steel plate from being scratched or worn during transportation and installation.

4. Significant sound insulation and sound absorption effects: PU edge sandwich panel can significantly reduce noise transmission, and are especially suitable for places where designated flights pass. In addition, after using rock wool roof panels, the indoor sound caused by the impact of rain and hail on the building's roof steel panels is also significantly reduced. Through testing, in accordance with ISO 717/82 and UNI 8270/7 standards, a sandwich panel with a density of 120kg/m³ rock wool as the core material was selected, and the sound insulation effect can reach RW=29~30 db.

Widely used in steel structure factories, power plants, power equipment companies, automobile exhibition halls, cement warehouses, steel structure offices, airport terminals, train stations, sports venues, large supermarkets, logistics centers and other steel structure buildings.
