Calcium Silicate Boards is mainly made of Portland cement and silicate materials as base and cellulose fiber strengthen, forming in one time with high pressure (4000 ton) and fumigation(autoclave), Which 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, external wall panel, exterior wall cladding, paneling, flooring, back-liners, skirting lines, prefabricated structures, door shutters etc.
For example: Business building, Entertainment facility, supermarket, hotel & restaurant, factory, warehouse, apartment building, hospital, theater and station etc.
