High security welded mesh panel fencing system for offshore petrochemical projects
High Security Welded Mesh Panel Fencing System for Offshore Petrochemical Projects | 358 Mesh Panels & Galfan Wires
This high security welded mesh panel fencing system is designed for offshore petrochemical projects that require strong perimeter protection, long-term corrosion resistance, and reliable performance in harsh marine environments. The project combines 358 mesh panels, welded V bend panels with zinc-alu and powder coating, and galfan wires to deliver a durable anti-climb fencing solution for critical facilities. High-security welded mesh systems are commonly specified for sites that require small apertures, difficult-to-cut panels, and corrosion-resistant finishes, especially in petrochemical and coastal environments.
Project Scope
This offshore petrochemical fencing project requires a complete high security fencing system, including:
The system is specified for demanding industrial conditions where perimeter protection, anti-climb performance, and long service life are essential.
Galfan Wires
Galfan Wire Specification
Galfan wires are supplied in a zinc 95% / aluminum 5% composition, with wire sizes of 4.0 mm, 4.5 mm, and 5.0 mm. The tensile strength is 550 N/mm², and the coil size ranges from 200–500 kgs.
Galfan-coated wire is widely used in high-security fencing because the zinc-aluminum alloy coating provides excellent corrosion resistance, especially when combined with powder coating in coastal or petrochemical applications.
Welded Mesh Panels
The project includes welded mesh panels manufactured to high-security standards, with small mesh openings designed for anti-climb and anti-cut performance. High-security welded mesh products are commonly presented with detailed specification blocks and standards references, including EN 10223-7, coating thickness, and tensile strength requirements.

Why This System Is Suitable for Offshore Petrochemical Projects
Offshore petrochemical facilities require fencing systems capable of withstanding salt-laden air, high humidity, and long-term exposure to aggressive environments. This is why the project combines galfan coating, zinc-aluminum protection, and powder coating while maintaining a tight and secure mesh structure for anti-climb protection.
High-security welded mesh fences are commonly specified for industrial and petrochemical sites because the small apertures improve perimeter defense, while the advanced coating system helps extend service life in harsh conditions.

Coating and Corrosion Resistance
To ensure long service life in offshore and petrochemical environments, the system uses Galfan and powder coating protection. The Galfan layer and powder coating work together to improve corrosion resistance and help the fence maintain a stable appearance and performance under challenging weather and salt spray exposure.
The use of RAL 6005 gives the project a clean, professional perimeter finish that fits industrial environments while maintaining a low-visibility security profile.
Application Advantages
This fencing system is suitable for offshore petrochemical projects, industrial facilities, and other high-security perimeter applications where the fence must provide:
· anti-climb protection
· anti-cut resistance
· high structural rigidity
· strong corrosion protection
· visibility for surveillance
· long-term outdoor durability
This high security welded mesh panel fencing system is engineered for offshore petrochemical projects that demand reliable anti-climb protection, excellent corrosion resistance, and long-term outdoor durability. With 358 mesh panels, welded V bend panels, galfan wires, and powder-coated zinc-aluminum finishes, the system is built for performance in harsh marine and industrial environments.
FAQ
Q1: What makes this fencing system suitable for offshore petrochemical projects?
A1: It combines high-security welded mesh panels, welded V bend panels, Galfan wires, and powder coating to deliver both perimeter security and corrosion resistance in harsh environments.
Q2: Why is 358 mesh commonly used for high-security fencing?
A2: 358 mesh is widely used because its tight mesh openings and welded structure make climbing and cutting difficult, which is why it is often positioned for high-security sites.
Q3: What is the benefit of Galfan coating?
A3: Galfan coating improves corrosion resistance by combining zinc and aluminum protection, which is valuable for offshore and coastal applications.
Q4: Why is powder coating important?
A4: Powder coating adds another protective layer, supports color consistency, and helps extend the service life of the fencing system.
Q5: Can this system be customized for other industrial projects?
A5: Yes. The same technical framework can be adapted for other industrial, petrochemical, and critical infrastructure projects with different panel sizes, coatings, and wire specifications.
