Color-coated steel sandwich panels is a surface material, self-extinguishing polystyrene, polyurethane, glass wool, rock wool as core material with a hot curing adhesive in a continuous compounded by heat and pressure molding machine The lightweight building board. With light weight (weight of concrete roof 1/20 to 1/30), insulation (thermal conductivity value (0.034W / mk), construction speed (no wet work, not re-decoration Color Sandwich construction period can be shortened by more than 40%), bright (no surface decoration, color galvanized steel coating retention period at 15-30 years) is characterized by Jincheng steel sandwich panel, is a set of load-bearing, heat mainly for color pressure plate and polyurethane foam polyurethane foam polyether or polyester as the main component, waterproof, decoration in one of the new Structural Materials. Caigang polyurethane composite board Caigang polyurethane sandwich composite panels of the raw materials component A, polyisocyanate Cyanamid ester component B primary components .A, B two components once the mixing occurs at the same time both in the event of chain reactions by reaction and coaches, will absorb moisture from the air color steel sandwich panel prices to reflect the occurrence of deflation, generating a large number of bubbles in a very short period of time to form a foam structure solidified
