Community noise barrier characteristics: 1. The sound volume: the average sound insulation quantity should not be less than 35 db; 2. The high absorption coefficient: the average absorption coefficient should not be less than 0.84; 3. Village corrosion resistance durability of noise barrier: the product should have water resistance, heat resistance, uv resistance, will not lower the quality of performance or anomalies caused by rain water temperature changes. Products adopt aluminum alloy plate, galvanized volumes galvanized board, glass wool, H steel column surface of anticorrosion fixed number of year in more than 15 years. 4. Beautiful: can choose a variety of colour and modelling are combined, with the surrounding environment harmonious, form a beautiful scenery line. 5. Economy: prefabricated construction, improve the work efficiency, shorten the construction time, construction costs and labor can be saved.
6. Convenience: in parallel with other products installation, easy maintenance, easy update. 7 neighborhood noise barrier. Light: noise barrier series products have the characteristics of light weight, can reduce the bearing load of elevated light rail, highways, can reduce the cost of the structure. 8. Fire: using superfine glass wool, due to its high melting point, nonflammable, fully meet the requirements of environmental protection and the code for fire protection. 9. High strength: combined with climatic conditions in different parts of our country, fully test virtual wind load in structure design. Through the production line to suppress grooves increase strength. 10. Waterproof, dustproof, material design fully consider waterproof, dustproof, get wet in the rain in the dust or the sound absorption performance is not affected in the environment, structure has been set in the dirt drainage measures, avoid internal water components. Ann mads village micro-perforated resonance cavity acoustic noise barrier in heavy rain environment sound absorption performance is not affected, in particularly evident in the low frequency noise reduction.
