Metlock™ Noise Barrier –

METLOCK™ noise barriers are designed to reduce noise using sound absorption principles and are optimized to meet EN14388/89 standards as well as IRC, MoRTH, and other international traffic noise barrier guidelines. These systems utilize mono- and bi-facial absorptive panels to manage surrounding noise, creating quieter environments for nearby residents. The modular post and panel design simplifies installation for various noise control applications.

Why Choose Metlock Noise Barrier? –

  • Material and Construction: Metlock™ noise barriers typically consist of a porous material sheet on the noise source side for absorption and a solid, reflective side facing the protected receptor. These are often sandwich panels made of steel or aluminum with a sound-absorbing material in between. The construction includes mineral/rock wool (water repellent) and solid metallic panel.
  • Absorption Technology: As an absorptive noise barrier system, METLOCK directly absorbs sound intensity and dissipates energy through sound-absorbing materials.
  • Customization: Metlock™ system allows for aesthetic and performance customizations to meet specific project needs, performing effectively across low, medium, and high-frequency bandwidths.
  • Compliance: Metlock noise barriers meet acoustic, mechanical, and physical performance standards in accordance with EN-14388, IRC:SP-130, and IS standards.
  • Components: The main frame support structure is made of hot-rolled medium and high tensile structural steel universal beams, welded at a steel base plate, complying with IS 2062 standards. Vertical posts are fixed to a reinforced concrete base using chemical anchor fasteners. The entire structure is coated as per IS standards.
