Industrial plants, warehouses: sandwich panels are mainly used in industrial plants, warehouses roof and facade. Past industrial plants to use more precast concrete roofing or asbestos. With the rapid spread of light steel structure, sandwich also known for its many significant advantages to replace the above-mentioned two kinds of material. At the same time providing better insulation effect, sandwich panels with the mature development of light steel structure, light steel system can truly reflect the light, fast and efficient, flexible layout and a series of advantages, which in the current single-storey factory building It has become the preferred option. As for the multi-industrial plants, in addition to the roof top of houses can be sandwich panels, the exterior wall sandwich panels can also be used as a flexible arrangement, the scaffold Caigangyanmian sandwich panel, color-coated by changing color and shape to beautify the exterior of the building purposes. For constant temperature and humidity requirements of industrial buildings, using thermal performance is superior to brick sandwich as the envelope material, Jincheng Caigangyanmian sandwich panels can be significant savings in operating costs after completion. By automatic continuous sandwich composite molding machine, Handan Caigangyanmian sandwich panels, outer layer is a high-strength material (eg, color galvanized steel, stainless steel plate), the inner layer is a lightweight insulation material (flame retardant polystyrene ethylene, mineral wool, polyurethane, etc.) by automatic molding machine, high-strength adhesive bond between the two, Caigangyanmian sandwich panels, pressurized, trimming, notching, blanking from sheet metal. Sandwich only has good insulation, thermal insulation and moisture and other physical properties, but also has good mechanical properties of shear, as a contemporary popular new building materials. Please use rock wool fire retardant plate (glass wool) color steel sandwich.
