Metal sound barrier includes metal louver, metal mesh hole sound barrier.Metal shutter sound insulation board is a small metal box, which is shutter holes, sound-absorbing hole opening rate is more than 25%, there is no hole back plate, the middle is glass and sound-absorbing sound-absorbing cotton blanket, sound-absorbing cotton to absorb sound, sound-absorbing carpets for anti-dust, waterproof, fire prevention, the sound insulation of the blind hole plate has a benefit is that it is down hole, such as rain, snow or dew will not enter into.
Advantages of metal louver sound barrier:
1) High sound insulation capacity: average sound insulation capacity is 36 dB.
2) High sound absorption coefficient: average sound absorption coefficient is 0.85.
3) Weather resistance and durability: water resistance, heat resistance, uv resistance, and no degradation or quality abnormality caused by rain temperature change.Heibei Jinbiao metal louver sound barrier adopts aluminum alloy coil, galvanized coil, glass wool, H steel column surface galvanized treatment anticorrosion life of more than 30 years.
4) Beauty: A variety of colors and shapes can be selected for combination to coordinate with the surrounding environment to form a beautiful landscape.
5) Economy: Assembly construction can improve work efficiency, shorten construction time and save construction cost and labor cost.
6) convenience: in parallel with other products installation, easy maintenance, convenient update
7) security: acoustic board with phi 6.2 wire connection on both ends fixed, prevent secondary injury, property damage
8) light: sound-absorbing board N series products have the characteristics of light weight, smooth rice quality less than 25 kg, the bearing load of highway, which can reduce light can reduce the cost of the structure of
9) fire: use superfine glass wool, due to its high melting point, nonflammable, fully meet the requirements of environmental protection and the code for fire protection, fire rating up to A level
10) High strength: combined with climatic conditions in different parts of our country, the structure design of fully considering the wind load will use the 1.2 galvanized sheet, through the automatic production line, the suppression of grooves in order to increase strength, make the product resistance level 10-12 typhoons, compressive 300kg/m².
11) waterproof and dustproof, shutter type when the design mature waterproof and dustproof, the Angle to 45, for its sound absorption in the dust, or in the rain environment is not affected, structure has been set in the dirt drainage measures, avoid internal water components
