It’s a kind of composite aluminum sheet manufactured by using aluminum sheet as its front sheet and corrugated core as its core material, by selecting back sheet (or non-composite back sheet) in accordance with an application environment and the requirements of the plate, and by adopting composite aluminum plate production technology, with such features as a wide plate surface, good flatness, small falling deviation size and so on.
The core sheet of the aluminum corrugated sheet is of the water ripple shape, which forms an air passageway between the front panel and rear panel, that is, a hollow system, so that the sheet is among the best products for heat insulation. Under the action of solar radiation, the air in the passageway rises in temperature and flows upwards, taking the heat away and having the performance of insulating against heat. In a cold area, the sealing of the upper and lower ends of the corrugated passageway in sunlight in the daytime helps store heat energy and reduce the running off of indoor heating, having the performance of heat insulation. The remainder of the corrugated sheet in engineering can be recovered by 100%, being environmentally-friendly and pollution-free.
