Sound Proof Fence Panels China Factory Sound Proof Barrier 246050080mm Viaduct Sound Barrier

Urban noise isn’t going away, but the way we tackle it is changing fast. Municipal buyers and EPC contractors now ask for verified acoustic performance, faster installs, and sensible pricing—preferably all three. This is where, to be honest, the latest Chinese-made viaduct barriers have been punching above their weight. I spent a week talking with site managers and checking factory notes in Hebei, and it seems this model hits a very sweet spot for rail and highway edge projects.

What’s trending

Two big shifts: more projects specify EN/ASTM/ISO-backed data, and more owners want modular sections that swap out in minutes. This panel—let me shorthand it as the Sound Proof Fence Panels China Factory Sound Proof Barrier 246050080mm Viaduct Sound Barrier—leans into both trends with a compact 500 mm height module that stacks cleanly and keeps logistics simple.

Core specifications

How it’s made (short version)

• Materials: galvanized iron skins (perforated/solid combo), frame profiles, mineral wool infill, non-woven veil.
• Methods: sheet forming, perforation, frame welding, HDG, powder coating, assembly, sealant finish.
• Testing: ISO 10140 lab for Rw; ASTM E90/E413 STC mapping; EN 1793/1794 for road barriers; salt-spray to ASTM B117 (optional).
• QA: dimensional checks, coating thickness, rivet pull tests, random IL spot checks on mock-ups.

Where it’s used

Viaducts and overpasses, ring roads, light rail corridors, substation perimeter fences, chiller yards at malls, even factory edges near residential zones. Many customers say the modular height keeps installation times pleasantly short—less crane time, fewer lane closures.

Real-world notes and mini case studies

• Coastal viaduct retrofit (East China): ≈ 24 dB(A) reduction at receptor facade; powder coat held up well after typhoon season.
• Urban LRT segment: night installs; crews liked the 500 mm modules—easy to swap damaged pieces without tearing a long run.

Vendor comparison (quick take)

Customization and options

Panel thickness tweaks, anti-glare caps, see-through poly sub-panels near driver sightlines, and bolt-on maintenance doors. Post spacing usually 2.46 m center-to-center; hardware spec adjusts to local codes. Honestly, the green finish blends better than I expected on concrete viaducts.

Why it’s a solid pick

• Verified acoustics with practical, stackable modules.
• Durable coatings; corrosion control baked in.
• Fast installation; low life-cycle costs.

If you need a no-drama, spec-backed barrier for elevated roads or LRT, the Sound Proof Fence Panels China Factory Sound Proof Barrier 246050080mm Viaduct Sound Barrier deserves a spot on the shortlist.
