Sandwich panel

Sandwich Panel uses colour coating steel sheet as surface board, it uses self-extinguishing polystyrene, Polyurethane, crystal cotton and rock cotton as core material, it is over-light architectural board heated and pressed in continuous moulding machine with solidifying glue. It has excellences of small weight(1/20---1/30 of concrete roof), heat preservation, heat insulation(its heat conduction coefficient is 0.034W/mk), rapid construction speed(operate without humidity and needn't repeated fitment), is a new type protection structural material congregates bearing, heat preservation and water resistance. The product is used to purify factory roof, protect and purify product industrial factory, storehouse, refrigeratory;Large-span roof board, adding layer for original building, temporary office, store, market and sentry box.
