As urban areas grow and transportation networks expand, noise pollution has become a major challenge for both residential communities and critical infrastructure. To address high noise levels in sensitive environments, fully enclosed noise barriers have emerged as one of the most effective and reliable solutions.
At Hebei Jinbiao Construction Materials Tech Corp., Ltd., we specialize in designing and manufacturing fully enclosed noise barrier systems that deliver maximum acoustic performance, long-term durability, and exceptional safety for highways, railways, industrial plants, and environmental protection projects.
A fully enclosed noise barrier is a complete acoustic structure that surrounds a noise source from multiple directions—typically top, sides, and partially the bottom—creating a closed or semi-closed acoustic tunnel.
This design significantly reduces the transmission of traffic or industrial noise to surrounding areas.
Common applications include:
Elevated highways and viaducts
Urban rail transit and metro lines
High-speed railways
Bridges passing near residential areas
Industrial areas with high noise output
The enclosed design effectively blocks both direct and reflected noise.
Combined with our sound-absorbing metal panels, acrylic/PC transparent panels, and acoustic louvers, the system achieves excellent noise reduction performance, ideal for densely populated or highly sensitive locations.
Our enclosed barriers use high-strength steel frameworks and precision-engineered connectors, ensuring stability even under:
High wind loads
Heavy rainfall
Snow accumulation
Vibration from vehicles and trains
All structures comply with international engineering and safety standards.
We provide multiple material options to fit different project environments:
Galvanized steel acoustic panels
Aluminum sound-absorbing panels
Hot-dip galvanized support frames
PMMA / Polycarbonate transparent panels
Anti-UV, anti-corrosion, and anti-aging coatings
These materials ensure long service life and reduced maintenance costs.
For bridges, urban railways, and city centers, we offer clear acrylic or polycarbonate panels to maintain visibility and reduce the sense of enclosure.
This improves safety and ensures architectural harmony with the surrounding landscape.
We support complete customization based on engineering drawings:
Panel thickness
Frame structure
Tunnel width & height
Ventilation solutions
Lighting integration
Access doors and maintenance spaces
