China JINBIAO Metal microporous noise barrier manufacturer
Metal Microporous Noise Barrier is a highly efficient acoustic barrier system designed to reduce environmental noise generated by highways, railways, industrial equipment, and urban infrastructure. The barrier is made from perforated or microporous metal panels combined with high-density sound-absorbing materials, allowing it to effectively absorb and block noise transmission.
The microporous structure on the metal surface allows sound waves to enter the panel and be absorbed by the internal acoustic materials, significantly reducing reflected noise and improving overall noise reduction performance. Compared with traditional noise barriers, metal microporous noise barriers provide better sound absorption, higher structural strength, and longer service life.
The panels are typically manufactured using galvanized steel or aluminum sheets with advanced corrosion-resistant surface treatments such as powder coating or hot-dip galvanizing. This ensures excellent durability even in harsh outdoor environments such as highways, bridges, or coastal areas.
Metal microporous noise barriers are widely used in transportation infrastructure and industrial facilities where effective noise control and environmental protection are required.

An important advantage of the JINBIAO design is the fact that the panels are made of aluminum or galvanized sheet. They are self-supporting and therefore don’t need an additional frame. This has a positive impact in the pricing.
A double-sided EPDM-sealing provides continuous soundproofing. And every individual panel can be exchanged and replaced without any problems if damage should occur.
Also transparent panels are possible
JINBIAO does not only guarantee high noise absorption, but it also provides excellent views due to its transparency. Embedded polyamide threads offer a maximum safety standard and are mainly applied for noise barrier on bridges in case of need.
