In an uncertain global climate, the development of color steel sandwich panels is a great help to the construction industry. In many ways, materials such as color steel plates can be used to build houses or plan beautiful cities.Country has many houses will use caigang sandwich panels for the animal shelter from the rain, its heat preservation performance is superior, and relatively easy to install, than fix the build by laying bricks or stones a cement brick houses simpler, and don't need a lot of manpower material resources, can be picked farmhouse that today's seamless splicing technology, adopting caigang sandwich board's building, more warm wind, the rest of the world cold, high density of sandwich layer and seamless metal organic unifies in together, the sandwich layer in a double metal panel foaming curing molding directly. General house at the time of maximum temperature difference between indoor and outdoor metope, the surface will produce water vapor dew, such not only can accelerate the corrosion degree of main building materials, construction will also reduce the construction house wife or animal heat preservation effect of the building, not in the warm house, not solid wall, and who can live at ease, and caigang sandwich board manufacturing process, strengthened the construction of this aspect, adopts closed bubble formula structure, efficient to eliminate surface condensation of water vapor, enhance the capacity of heat preservation of building. In today's variety of building materials market, color steel sandwich board in the sale of polystyrene sandwich board is the most widely used. It is not only light weight, convenient transportation construction installation, the cost of production and it is also quite low, the surface of the metal plate have a certain fire protection features, fire-resistant capacity up to 1000 degrees Celsius, the surface of the coating are produced through special processing, but the polystyrene core material is not non-combustible, it also can burn, this rain rock wool sandwich panel cannot be compared, at the same time belongs to insulation sandwich color steel plate, rock wool core material is generally use of basalt and other natural raw material to produce it, so it is to belong to the absolute core incombustible materials.
