Features 1) Large sound insulation: The average sound insulation is 36dB. 2) High sound absorption coefficient: the average sound absorption coefficient is 0.85. 3) Weather resistance and durability: The product has water resistance, heat resistance, UV resistance, and will not reduce performance or abnormal quality due to changes in rain temperature. The products are made of aluminum alloy coils, galvanized coils, glass wool, and H-steel columns. The anticorrosion period is more than 30 years. 4) Beautiful: A variety of colors and shapes can be combined to coordinate with the surrounding environment to form a beautiful landscape. 5) High strength: Considering the different climatic conditions in various regions of our country, the wind load is fully considered in the structural design. Using 1.2mm galvanized sheet, through the automatic production line, the groove is pressed to increase the strength, so that the product can withstand 10-12 typhoons, and withstand pressure of 300. 6) Waterproof and dustproof: The louver type is designed with full consideration of waterproof and dustproof. Its angle is set to 45�°, and its sound absorption will not be affected in a dusty or rainy environment. Dust drainage and drainage measures have been installed in the structure. Avoid water accumulation inside the components. 7) Durable: The product design has fully considered the wind load of the road, the collision safety of traffic vehicles and the open-air corrosion protection in the whole climate. The product adopts aluminum alloy coil, galvanized coil, glass wool, and H steel post with galvanized surface treatment. The company guarantees that the products will not corrode, change shape, sound absorption and sound insulation effects within 30 years
