Metallic Noise Barriers

Metallic Noise barriers is the most economical choice of Noise barrier solution for outdoor. The main factors that are taken into consideration for an outdoor structure firstly is its ability to perform the intended job in the given environment and have a decent look.

Metallic Noise Barriers are of two types. It can be a one sided noise reflective barrier or a barrier that has acoustic properties on both sides. The two sided noise barrier will deflect sound from either side thereby creating a sound wall. The barrier panels are light in weight as both steel and aluminium are light weight. This makes it easy to install as well.

Composite material:

A Metallic Noise barriers could be made of steel, aluminium or stainless steel. Steel is the least expensive material and has many properties that defines it as an appropriate material for an outdoor noise control barrier. Aluminium is also known for its durability, light weight and weather resistance.

The look of the barrier is an important factor that we take into consideration. Metallic Noise Barrier are placed outdoors in very prominent locations. Most of the people who see it may not be aware of its utility however what does stand out is its aesthetic appeal. We try and ensure that the Metallic Noise Barriers blend into the environment as much as possible and add to the surrounding beauty.

Metallic Noise Barriers Applications

Metallic Noise Barrier are very effective for highway noise, airport noise, railway and metro lines noise, industrial noise, construction site noise and any other noisy environments. We have specially designed these noise barriers to suit the Indian terrain and weather conditions. Our Metallic Noise Barriers are designed to meet a 36 STC rating. We provide a total service from manufacture, delivery to installation. All our materials are quality tested during each stage of manufacture and before delivery to ensure quality standards and high performance.


Metal is a good reflector of sound and Metallic Noise Barriers are coated with special sound mitigating material which makes it effective as sound reflective barrier. Absorptive Metallic Noise Barrier have perforation on one side which helps it to absorb the sound rather than deflect it.

We are specialized in Highway Noise Barrier, Railway Noise barrier,Road Noise barrier solutions

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.
