More than a decade ago, the sound barriers of high-speed railways made of different metals, after being exposed to the wind, water, sun, and time, have begun to have quality problems one after another, such as rust and oxidation.
Only the sound barriers made of aluminum alloy have excellent quality.
For metal plates of the same thickness, the weight of aluminum alloy is lighter than that of stainless steel and iron.
There is an oxide film on the surface of aluminum alloy, which can protect the aluminum alloy from rusting in the outdoor environment of wind and rain.
The hardness of 6061 aluminum alloy is also suitable for making sound barriers for high-speed railways, effectively isolating noise.
In fact, there are many scenarios for the use of sound barriers. On both sides of the high-speed railway and along the highway, it not only isolates noise, but also blocks some wind and sand or birds and insects, which to a certain extent protects vehicles or high-speed railways traveling at high speed on the road.
Some cities have a large temperature difference between day and night.
If the outdoor sound barrier is made of 6061 aluminum plate it can quickly conduct temperature and will not crack due to low temperature.
It is indeed more suitable than other metals.
If your city is replacing a new high-speed railway sound barrier, or your factory is producing sound barriers, please contact us.
We can customize the production according to your needs, alloy, temper, thickness width length.
