Features of Metallic Noise Barrier

The Envirotech Metallic Noise barriers are a preferred option for a number of applications based on its features.

Weather proof: The metallic noise barriers are made of steel or aluminium that are galvanised to ensure that they are resistant to all kinds of weather. The barrier sheets are also UV coated to ensure that they are not affected by the atmosphere.

Non-corrosive: Neither aluminium or steel are susceptible to rust or corrosion and hence the composite material is a sound choice.

Strong & durable: Metal is renowned for its strength and durability. Its galvanised coating also helps to ensure durability. The barriers will stand up against strong winds and storms. The strength of the metallic barriers also prevents damage due to malicious intent and a general destructive attitude.

Soundproofing: The noise barrier sheets have rubber lining at the joint to ensure that there is no noise leakage.

Fire retardant: The metallic noise barriers are classed as fire retardant material.

Weight: The metallic noise barrier sheets are light weight and recommended for installation in places such as bridges and flyovers. They are also used as noise barriers for overhead metro lines.
