Requires uniform zinc coating surface colors, no peeling, no shedding high-speed sample sound barrier without sagging, zinc coating thickness not less than 80um (600g/m2) insulation large: the average amount of noise 37db. Sound absorption coefficient is high: the average absorption coefficient of 0.84. Weathering Durability: The product has water resistance, heat resistance, UV resistance, will not be reduced due to temperature changes caused by rain or quality of performance anomalies. Appearance: choose a variety of colors and shapes are combined, coordinated with the surrounding environment, the formation of tapestry.
