PRODUCT SUMMARIZE

· Large sound insulation value: the average sound insulation value: 30~35dB (A).

· High sound absorption coefficient: the average sound absorption coefficient: 0.65~0.90

· Beautiful: variety of colors can be selected to fit shapes, assort with surrounding environment, and then become a spectacular scene.

· Environment durability: the product is waterproof, heat-resistant, and UV resistant. The performance will not be reduced and the quality will not be abnormal on account of rain, temperature change. The product made of aluminum alloy steel coil, galvanized coil, glass-fiber, H-section galvanized steel. The surface is treated with galvanizing; corrosion prevention length is over 15years.

· Convenience: parallel installation with other products, convenient maintenance, and update.

· Economy: fabricated constructions, improve efficiency, reduce construction time, save construction costs and labor costs.

· Fire-proof: using ultra-fine glass-fiber, as its high melting point, non-combustible, full meet requirements of environmental protection and fireproof norm, fire-proof rating up to A level.

· Light: sound absorption panel series features a light weight, reducing the load of elevated railway and overhead road, reducing structure cost.

· High strength: considered with various weather conditions in different regions, have to take virtual wind loads into account in structure design process. Increase strength through the product line grooves, consequently resistance to 12 typhoons.

· Waterproof, dustproof: adequately consider waterproof and dustproof function in shutter design. Because of the angle is 45°,absorption performance will not be affected in dusty and raining environment. There have been waterproof and dustproof measures in structure, to prevent the internal water logging. Micro-perforated cavity resonance acoustic absorption performance will not be affected in the rain environment, particularly against the low-frequency noise.

· Durability: product design has fully considered the wind load, vehicles crash safety and all-weather corrosion prevention. Products are made of aluminum alloy steel coil, galvanized coil, glass-fiber, H-section galvanized steel. We guarantee no corrosion in 15years, no distortion, sound absorption, sound insulation effect is not reduced.
