China Windbreak Fence Panels for Sale – Exporter Overview

Windbreak fence panels are engineered structures designed to reduce wind velocity and protect agricultural fields, construction sites, and storage areas.

Manufactured in China, these panels are supplied by exporters who comply with international shipping standards and can accommodate large volume orders.

Typical panel dimensions range from 2.4 m to 3.6 m in length and 1.2 m to 2.0 m in height, with a modular interlocking system that allows rapid assembly without specialized tools.

Technical Specifications

Key performance indicators include wind load resistance, deflection limits, and material thickness.

Material Options

Two primary material families are offered: hot‑dip galvanized steel and high‑density polyethylene (HDPE).

• Galvanized steel – tensile strength ≥350 MPa, zinc coating 275 g/m², suitable for corrosive environments.
• HDPE – UV stabilizer content ≥2 %, impact strength ≥30 kJ/m², resistant to chemical splash.

Applications

Windbreak fence panels serve specific functions depending on the sector they are deployed in.

In agriculture, panels lower wind speed at crop height, reducing soil evaporation and mechanical damage to seedlings.

On construction sites, they contain dust and debris, improving worker visibility and compliance with site safety regulations.

For bulk storage of granular materials, panels prevent product loss and limit the formation of wind‑driven piles that can obstruct access.

Customization Choices

Panels can be tailored to project requirements through adjustments in size, perforation pattern, and coating.

• Length – selectable from 2.0 m to 4.5 m in 0.5 m increments.
• Height – adjustable between 0.8 m and 2.5 m.
• Perforation ratio – 20 % to 50 % open area, influencing wind permeability.
• Coating – hot‑dip galvanizing, powder‑coat (RAL colors), or PVC lamination for extra chemical resistance.

Quality Control & Testing

Each production batch undergoes a series of inspections to verify conformance with specification.

• Dimensional check – laser measurement of length, width, and thickness within ±2 mm tolerance.
• Coating thickness – magnetic induction test confirming ≥55 µm zinc for steel panels.
• Wind tunnel test – sample panel subjected to 1500 Pa load, deflection recorded.
• Visual inspection – surface free of scratches, delamination, or inconsistent color.

Packaging & Shipping

Panels are stacked flat, protected with edge guards, and secured in steel frames for container transport.

• Flat‑stack – panels placed on pallets with interleaving corrugated sheets.
• Crated – wooden crates with foam corners for high‑value finishes.
• Palletized – standard 1.2 m × 1.0 m pallets, stretch‑wrapped.
• Container suitability – fits 20‑ft and 40‑ft dry containers, max 24 tonnes gross weight.
• Moisture barrier – VCI film applied to steel panels to inhibit corrosion during transit.

Lead Time & Sampling

Standard production lead time depends on order volume and material availability, typically expressed in weeks.

Stock‑size panels usually ship within 2‑4 weeks after receipt of purchase order.

Custom‑size or coated orders require 5‑8 weeks, including tooling and coating cure time.

Samples are provided upon request; a single panel sample can be dispatched via express courier within 3‑5 business days.

Frequently Asked Questions

Can dimensions be customized?

Yes, length, height, and perforation ratio can be adjusted to match site‑specific wind load calculations.

What information is required before quotation?

Project location, expected wind speed (basic wind speed or gust), panel dimensions, material preference, and quantity.

What materials are available?

Hot‑dip galvanized steel (grade Q235 or equivalent) and UV‑stabilized HDPE are standard options.

How is quality inspected?

Each batch undergoes dimensional verification, coating thickness measurement, wind tunnel deflection testing, and visual inspection.

What packaging methods are available?

Flat‑stack on pallets, wooden crates, or stretch‑wrapped pallets, all with edge protection and moisture barriers as needed.

How are export shipments protected?

Panels are secured in steel frames, corner protectors applied, and containers loaded with dunnage to prevent shifting.

What is the typical production lead time?

Stock items: 2‑4 weeks; custom items: 5‑8 weeks, subject to material availability.

How are samples arranged?
