1220×2500mm Perforated Steel Sheet For Highway Noise Barriers
Galvanized slotted metal sheet material properties:
Made of galvanized steel plate as the base material, it has good corrosion resistance. The zinc layer can effectively resist the erosion of outdoor wind, rain, ultraviolet rays, etc., and the thickness of the zinc layer is usually ≥85μm, in line with the GB/T 13912-2022 standard, which can make the service life of the metal plate reach more than 15 years.The grooved structure is created by the roll - forming process. This structure can increase the reflection path of sound waves and is also conducive to enhancing the strength of the plate, improving its wind resistance and durability.

Surface Treatment:
Generally, electrostatic spraying is carried out on the surface of the galvanized sheet to form a protective film, further improving the anti - corrosion performance. At the same time, different colors can be selected according to requirements, such as green, blue, white, gray, etc., to make the sound barrier coordinate with the surrounding environment.In addition to electrostatic spraying, there are also surface treatment methods such as fluorocarbon spraying, which can provide better weather resistance and appearance texture.
Acoustic Performance:
The galvanized grooved metal plate is usually used in combination with sound - absorbing materials (such as glass wool, rock wool, etc.) to form a sound - absorbing structure. The grooved structure helps sound waves enter the interior of the plate and be absorbed by the sound - absorbing material, so as to achieve the effect of reducing noise.Generally speaking, this kind of sound - barrier plate, combined with suitable sound - absorbing materials, can have an average sound - absorption coefficient of more than 0.84, which can effectively reduce the noise generated by the driving of vehicles on the highway.
