In the field of architecture, with the development of science and technology, the sandwich color steel plate appeared in the last century has evolved a variety of properties.At first, color steel plate was used by residents in the United States. At that time, there was no feeling of heat preservation of color steel sandwich plate, only a simple building function, and only a game room for children to play in. However, there were considerable potential safety hazards, such as insufficient firmness and poor chemical stability. However, the color steel plate cast in later stage was found from its firmness and compression resistance. A new generation of single-layer color steel plate is made. Many people use it to build roofs in the mould and rainy season to resist the attack of rainstorm. But in the hot summer, this kind of plate can not reduce the heat source, but will produce heat transfer. In the high temperature weather, the temperature in the house will continue to rise with the sun time, which also leads to a period of low sales of color steel plate. However, in recent years, the scientific development achievements are outstanding, and the continuous research and development and manufacturing, and now there is the thermal insulation color steel sandwich panel, The product is made of two layers of metal panel or other material panel plus foam sandwich layer. The coating of metal panel is already heat insulation coating, with small thermal conductivity, which has a strong restraining effect on the heat transfer effect, and will not produce the phenomenon of high temperature transfer from the outside to the inside of the house. The temperature in the house will be kept in the general comfortable temperature, which is also a lot of houses will use the color steel sandwich board to withstand the summer heat at present. Moreover, this kind of metal plate is very convenient in processing. It can be made into various shapes and patterns according to the requirements. Nowadays, large factories and engineering sites use color steel sandwich plates, rock wool color steel plates and other plates to build temporary mobile houses for migrant workers. In Europe, new environmental protection building materials are also used to build residential houses, among which color steel sandwich plates are used Among them, the current production process is increasingly developed, and the products developed in this environment are more and more environmentally friendly.
