Product features:
1) High noise insulation index: average 36dB. (Conditional sound-absorbing cotton 48K , thickness 80 ¡Á height 500 ¡Á length 2970 )
2) High sound absorption coefficient: average absorption coefficient 0.83. (Conditional sound-absorbing cotton 48K, thickness80 ¡Á height 500 ¡Á length 2970)
3) Weatherability (weather resistance) and durability: the product is water resistance, heat resistance, resistance to UV light, it does not decrease the performance or cause quality abnormity because of the rain or temperature. Product is made of aluminum alloy rolling coil plate, zinc-plated rolling coil plate, glass wool. The anticorrosion life span of zinc-plated surface finish for H vertical steel columns is 15 years.
4) Beautiful: it can be assembled with a variety of colors and styles to coordinate with the environment and surroundings.
5) Economical: prefabricated construction, improving work efficiency, shortening construction time, saving construction costs and labor costs.
6) Convenient: it can be installed with other products, it¡¯s easy to maintain and easy to update.
7) Safe: two ends of the sound-absorbing plate are connected and fixed with ¦Õ6.2 steel wire cable to prevent secondary damage, personnel harm and damage to property.
8) Light: noise-absorbing plate N Series is light weight (below 25 Kg per square meter), which can reduce the loads of elevated highway bridges and light rail; it can also reduce the structure costs.
9) Fire resistance: it¡¯s made of superfine glass wool, it¡¯s nonflammable because of its high melting point which can fully satisfy the environmental protection and fire safety requirements. It¡¯s fireproof grade up to A Level.
10) High strength: with all the different climatic conditions of the country, the wind load is fully taken into account when designing the structure. With 1.2 mm zinc-plated plate, through automated production lines, repression of the notch to increase the strength, it enables the product to resist 10-12 grade typhoons, its resistance compression strength up to 300 kg / sq.m.
11) Waterproof, Dustproof: 45 ¡ãVenetian blind (louvered) design to prevent from water and dust. In dusty or rainy environment its sound absorbing performance is not affected, it is equipped with dust exhaust and drainage measures to avoid the accumulation of water inside it.
12) Durable: the product design has fully taken the wind load of the roads, crash safety of traffic and the open-air anticorrosion of all kinds of climate into consideration. The product is made of aluminum alloy plate, zinc-coated steel plate, glass wool, zinc-plated surface finish of H vertical steel columns.
