Zhongcaijianhong in fiscal polyurethane sandwich panel is to choose a two-tier high-quality color-coated steel or other pressure type of precision sheet metal surface material to do, roll forming, into the middle of polyurethane foam flame- retardant liquid, after the high-pressure foam Curing process, and other specific conditions, with high-powered panel of metal bonding properties by COMPOSITE beautiful formation, construction of the plate just tough. With fire, heat, water, noise, and other characteristics of the building by the high quality of effects of the appearance, is the world's most forward-looking energy-efficient insulation, green, artistic ideal of building construction sheet
