Applications & Project Use Cases

Highways & Elevated Expressways

Installed along road shoulders and median strips to shield residential communities from tire-pavement noise.

High-Speed & Freight Railways

Low-height and full-height trackside barriers built to withstand dynamic pressure waves caused by passing high-speed trains (up to 250 km/h).

Power Substations & HVAC Cooling Towers

Perimeter structural enclosures housing transformers, chillers, and industrial exhaust blowers.

Construction & Demolition Sites

Modular hook-and-loop acoustic curtains mounted to temporary chain-link fencing to meet municipal nighttime noise ordinances.

Customization & Installation Systems

Fabrication Customization
Structural Post Matching: Custom HEA, HEB, or UC steel columns pre-drilled with base plate mounting holes, stiffener plates, and top cap brackets.

Color & Surface Finishes: Dual-color powder coating matching RAL color charts; anti-graffiti clear coat top layers applied upon request.

Integrated Emergency Doors: Pre-hung acoustic access doors with panic hardware built into the barrier line without creating sound leaks.

Installation Workflow
Foundation & Anchor Embedment: Cast-in-place concrete footings with pre-set anchor bolt clusters or driven steel pile pipes.

H-Beam Column Erection: Plumb and bolt steel posts onto anchor plates using leveling nuts and structural grout.

Panel Drop-In Mounting: Slide modular acoustic panels down between the flanges of adjacent H-beam posts.

EPDM Seal Integration: Insert continuous EPDM rubber gaskets along panel-to-column contact channels and horizontal panel tongue-and-groove joints to eliminate flanking noise leaks.

Testing & Quality Compliance

Quality control extends from coil slitting to hot-dip galvanizing baths and final powder curing.

Acoustic Chamber Testing

Full-scale panel assemblies are tested in reverberation suites to verify STC and NRC values per ASTM E90 and ASTM C423.

Wind Pressure Load Tests

Mechanical hydraulic pressing verifies panel bending deflection limits (< L/50) under simulated wind loads up to 3.0 kPa.

Salt Spray & Coating Integrity

Coated steel samples undergo 1,500-hour neutral salt spray testing (ASTM B117) to ensure zero undercut corrosion along punched edges.

Adhesive & Fire Retardancy

Non-combustible mineral wool cores are tested to ensure zero toxic smoke generation and thermal stability above 600 degrees Celsius.

Packaging & Project Logistics

Bundle Protection

Panels are packed on heavy-duty steel or treated timber skids, separated by non-scratch polyethylene foam strips.

Post & Hardware Crating

Steel posts are bundled with heavy PET strapping and corner guards; EPDM gaskets and fasteners are packed in waterproof wooden crates.

Container Loading Optimization

Tailored packing plans ensure maxed-out payload weight for 40ft HQ containers while minimizing transit vibration damage.

Site Sequence Tagging

Project-specific piece marking (matching CAD assembly drawings) printed on waterproof shipping labels for direct crane unloading to designated installation zones.

FAQ

Q: What structural wind load capacity can these noise barriers withstand?

A: Our standard metallic panel and H-beam systems are engineered for wind pressures from 1.5 kPa up to 3.0 kPa (equivalent to wind speeds exceeding 160 km/h), compliant with EN 1794-1 Annex A standards. Custom post spacing and web thickness calculations are provided per project geographic location.

Q: How do you prevent corrosion on punched metal holes during outdoor exposure?

A: Coil sheets are hot-dip galvanized before processing. After CNC punching and bending are completed, the entire fabricated panel shell undergoes multi-stage degreasing, zinc phosphatizing, and full-immersion architectural polyester powder coating (80 - 120 um thickness) to seal all raw punch edges against moisture ingress.

Q: What is the expected service life for highway and railway installations?

A: Steel and aluminum barrier systems manufactured with C4/C5 corrosion protection (ISO 12944) carry a design service life of 20 to 25 years. PMMA transparent panels feature anti-UV stabilization to maintain over 85% light transmission over a 10-year outdoor rating.

Q: How are panel-to-post joint gaps sealed to prevent acoustic leakage?

A: We supply custom extruded EPDM rubber profiles that slide into the H-beam flanges. These gaskets compress against the panel edges during installation, blocking airborne sound flanking and dampening panel vibration caused by wind or passing traffic.

Q: Can you supply complete engineering calculation packages for municipal bids?

A: Yes. Our engineering desk provides wind load calculations, post-foundation reaction forces, structural shop drawings (2D CAD & 3D Tekla models), and third-party acoustic test certificates to support contractor submittals.

Q: What is the production lead time for a 5,000 square meter highway project?

A: Standard manufacturing time is 20 to 25 working days following approval of shop drawings and color samples. Production can be batched to match site excavation schedules, with rolling container shipments dispatched sequentially.
