GF fireproof board is a kind of inorganic and non-combustible A grade composed of Xonotlite material, with stable physical and chemical properties. It does not deform in normal temperature or moist air and the temp. limited is up to 1100℃. It's almost a kind of permanent material, with the characteristics of lightweight, good dimensional stability, high strength. GF board is not only a fireproof board but also a decorating material. It can revise the deform of the steel beam and column, and can make the beam and column very streight and square. The effect of decoration can make very beautiful. The GF board can be sprayed plastic, painted, and also can stick ceramic tile directly on it, can reach the different requirement of decoration in any place. Our product can be cut, sawed, dug and nailed easily, then assembled at worksite without environment pollution. All this can be done together with other procedures such as piping erection, exhaust system, electric wire installation and so on,in any season. It's very simple and high efficient. Free from asbestos, GF board is a green building material, haven't any irritant smoke when burning and high temperature.
GF fireproof board have widely used in many major and demonstration project of China Construct Department, such as Jinan East City Mansions (26 storeys), Laigang Oriental Cherry Residence 1# (12 storeys), Jinan Eiffel Garden Residence, Jinan Weidong City, etc. And have already earned more honors from the customers.
