Exterior Fiber Cement Boards

These Exterior Fiber Cement Boards are mainly made of Portland cement and silicate materials as base and cellulose fiber reinforced, forming in one time then with high pressure (4000 ton) and fumigation(in autoclave 24 hours),so it has the advantages of high strength, anti-freeze, water-resist, fire-proof, damp-proof, sound-absorption , no distortion and no radiation...Etc. Used as suspended ceiling, partition, heat insulating board, base plate, billboard, external wall panel, exterior wall cladding, paneling, moving floor, desktop board, fire-resistant air pipe ,back-liners, skirting lines, prefabricated structures, door shutters etc.

Application areas: Business building, Entertainment facility, supermarket, hotel & restaurant, factory, warehouse, apartment building, hospital, and theater etc.
