The highway sound barrier is mainly composed of steel structure column and sound absorption and insulation panel. The column is the main load-bearing component of the sound barrier, which is fixed on the road anti-collision wall or the embedded steel plate beside the track by bolts or welding; The sound-absorbing and sound-absorbing board is the main sound-absorbing component, which is fixed in the H-shaped column slot through the high-strength spring clip to form a sound barrier. The design of sound barrier has fully considered the wind load of elevated highways, urban light rail, subway, impact safety of traffic vehicles and all-weather outdoor corrosion protection. It is beautiful and generous in appearance, exquisite in manufacture, convenient in transportation and installation, low in cost and long in service life. It is especially suitable for noise prevention of elevated highways, urban light rail and subways. It is the most ideal sound insulation and noise reduction facility in modern cities. Generally speaking, the higher the highway noise barrier, or the farther away from the noise barrier, the better the noise reduction effect.

Noise reduction effect	sound insulation 25-40db (A); Noise reduction coefficient 0.7-0.83
Style	upright, curved, angled, combined, etc
Material	aluminum alloy, color steel plate, galvanized plate, fiberglass, acrylic, PC plate, etc

1. Combined design, flexible and easy to install and disassemble; 2. The straight and flat highway sound barrier has a flat overall shape, while the upper sound-absorbing plate is in an isolated shape, which can more effectively control the diffraction of sound through the upper part of the screen, with a continuous frame structure as the main body in the middle; 3. Arc-shaped highway noise barrier, especially good noise reduction effect; It is beautiful and has good noise reduction effect; 4. The sound-absorbing board of highway sound barrier not only has good sound absorption and sound insulation effect, but also has excellent weather resistance and durability to ensure the service life; 5. Various colors and shapes can be selected for combination, and the landscape effect is ideal. According to the user's requirements, various types can be designed to be harmonious with the environment, coordinate with the surrounding environment, and form a beautiful landscape.
