The new type product can be substituted for traditional building material, and improve the productivity. This develops the working way into the dry and assembling direction. Meanwhile, because walls occupy less area, hosts of houses will have more space. Besides, the structure is light and the building is more anti –seismic and safer, but the cost is lower. This product is a new breakthrough in the material of wallboard reform.
