These barriers are engineered to attenuate broadband construction noise while meeting site‑specific wind, seismic, and handling requirements. Each unit is fabricated to OEM specifications, allowing integration with temporary fencing, scaffolding, or permanent perimeter systems.
Material Composition
Core layers consist of high‑density mineral wool or recycled polyester fiber, providing sound absorption coefficients above 0.85 at 500 Hz. Facings are hot‑dip galvanized steel (2.0 mm) or marine‑grade aluminum (1.5 mm) with a powder‑coat finish for corrosion resistance. Optional viscoelastic dampers increase panel loss factor to 0.12.
Acoustic Performance
Transmission loss (TL) and absorption are measured per ISO 10140‑2 and ISO 354. Typical values for a 100 mm thick panel are shown below.
| Frequency (Hz) | Transmission Loss (dB) | Absorption Coefficient |
|---|---|---|
| 125 | 22 | 0.30 |
| 250 | 27 | 0.55 |
| 500 | 31 | 0.78 |
| 1000 | 34 | 0.88 |
| 2000 | 36 | 0.92 |
Structural Design
Panels are 1.2 m wide and interlock via a tongue‑and‑groove system with stainless steel pins. Frame stiffness is designed to resist wind pressures up to 1.5 kPa without deflection exceeding L/200. Base plates include pre‑drilled holes for M16 anchor bolts, allowing rapid erection on compacted gravel or concrete pads.
Installation Methods
Units are delivered flat‑stacked on pallets. A two‑person crew can erect 30 linear meters per hour using a portable torque wrench for pin connections and a base plate leveling shim. No welding or hot work is required, reducing site safety permits.
Typical Applications
On active construction sites, these barriers lower perceived noise for workers by 8‑10 dB(A) and help meet local ordinance limits for adjacent residential zones. They are commonly deployed around piling operations, concrete sawing, and material handling zones where intermittent impact noise dominates.
Customization Options
- Panel thickness: 50 mm, 75 mm, 100 mm, 150 mm
- Facing material: galvanized steel, aluminum, stainless steel, fiber‑reinforced polymer
- Surface finish: smooth, ribbed, perforated for tuned absorption
- Mounting hardware: base plates, post‑mounted brackets, quick‑release clamps
- Color: standard RAL options or custom paint to match site branding
Quality Assurance
Each batch undergoes dimensional tolerance checks (±2 mm), core density verification (≥140 kg/m³), and acoustic spot testing per ISO 10140‑2. Weld‑free construction eliminates heat‑affected zone variability, ensuring consistent performance across production runs.
Packaging and Logistics
Panels are stacked with corrugated separators, wrapped in UV‑stabilized polyethylene, and secured with steel strapping. Standard pallet size is 1.2 m × 1.0 m, holding up to 20 m² of barrier. Containers are fitted with corner protectors to prevent edge damage during transit.
Frequently Asked Questions
| Question | Answer |
|---|---|
| Can dimensions be customized? | Yes, panel width, height, and thickness are adjustable to match site layout and acoustic targets. |
| What information is required before quotation? | Required data includes desired noise reduction (dB), exposure duration, wind load specifications, and any architectural constraints. |
| What materials are available for the facing? | Hot‑dip galvanized steel, marine‑grade aluminum, stainless steel, and fiber‑reinforced polymer panels are offered. |
| How is quality inspected? | Inspection includes dimensional checks, core density testing, and random acoustic transmission loss verification per ISO standards. |
| What packaging methods are available? | Standard flat‑stack pallets with polyethylene wrap and steel strapping; custom crate packaging is available upon request. |
| How are export shipments protected? | Corners are reinforced with cardboard edge protectors, and pallets are banded to prevent shifting during ocean or land transport. |
| What is the typical production lead time? | Lead time ranges from 3 to 4 weeks for standard configurations; custom finishes may extend to 6 weeks. |
