High-Wind WPC Fencing Solution for a Coastal Commercial Complex in Marseille, France

Case Detail

Project Name: Marseille Coastal Commercial Park Landscaping

Location: Marseille, France

Product Supplied: Co-Extrusion WPC Fence Panels & Aluminum Reinforced Post System

Volume: 2,400 Linear Meters (Loaded in 2 x 40'HQ Containers)

Completion Date: Spring 2026

1. Client Background & Project Scope

The client, a leading European commercial landscaping contractor, was commissioned to install a perimeter boundary and privacy fencing system for a newly developed oceanfront commercial park in Marseille, France.

The site required a modern, low-maintenance, and eco-friendly boundary solution that could maintain structural integrity in a harsh Mediterranean marine environment while seamlessly integrating into the surrounding architectural aesthetics.

2. The Challenges

The project faced three critical engineering and supply chain hurdles:

High Wind Loads & Saline Air Corrosion: The coastal site experiences strong Mistral winds (gusts exceeding 90 km/h) and constant exposure to salt spray. Traditional timber fencing rots rapidly under these conditions, while low-grade composites risk warping and color degradation.
Strict On-Site Installation Timelines: The main contractor had a tight 14-day window to complete the 2,400-meter fence perimeter before the commercial park's grand opening.
Landed Freight Cost Efficiency: To stay within budget, the contractor needed to maximize container payload without risking product damage during maritime transit.

3. Engineering & Manufacturing Solution

Our engineering team collaborated directly with the client’s project managers to custom-engineer a heavy-duty WPC fencing system:

A. Material Specification & Armor Protection

360° Co-Extrusion Armor: We utilized our proprietary Shield Series WPC profile—engineered with a 60% hardwood fiber, 30% HDPE, and 10% additive matrix—wrapped in a protective, anti-UV polymer outer shell.
Corrosion-Resistant Hardware: Replaced standard steel posts with 2.0mm high-grade anodized aluminum posts (> 18m coating), providing immunity to salt-air oxidation and zero rust risks.

B. Rapid-Assembly Interlocking System

Engineered custom tongue-and-groove interlocking panels that slided into slotted aluminum posts without specialized tools.
Reduced site installation steps by 35%, allowing a 3-person crew to erect up to 180 linear meters per day.

C. Optimized Logistics & Packaging

Custom panel lengths were manufactured at 1.78 meters to match standard European post spacing while precisely aligning with standard pallet dimensions.
Packaging Optimization: Heavy-duty steel-reinforced pallet packaging with edge-protectors allowed us to fit 1,200 meters per 40'HQ container, reducing landed sea freight cost by 18%.
