Products Description
9 Ribs PU Roof Sandwich Panels is a building material used for roofs. 9 Ribs polyurethane roof sandwich panels are also called polyurethane Great Wall panels because their cross-section looks similar to the shape of the Great Wall.

Polyurethane Great Wall panels generally use metal materials, such as color steel plates or aluminum plates as panels. Metal panels have good corrosion resistance and wear resistance, and can protect the internal structure of sandwich panels. At the same time, their appearance can be made of different colors and surface treatments according to needs to meet the aesthetic requirements of the building. The polyurethane Great Wall panel uses polyurethane (PU) material inside, which has excellent thermal insulation performance, can effectively reduce the heat transfer between the interior of the building and the external environment, and reduce energy consumption. In addition, polyurethane also has a certain sound insulation effect, which can improve the quietness of the room. Because its design uses 9 reinforcing ribs, it can maximize the strength and rigidity of the board, so that it can withstand greater loads. It is suitable for roof structures of various spans, ensuring the stability and safety of the sandwich panel during roof use.
9 Ribs PU roof sandwich panels are widely used in the roof structures of various buildings, including solar greenhouses, industrial plants, warehouses, commercial buildings, stadiums, residential buildings, etc. They are also used in agricultural buildings and animal husbandry buildings, which can provide a suitable growth environment for animals and plants, while meeting the requirements of building insulation, heat insulation, waterproofing, etc.
