For environments where conductivity, corrosion, or interference risks make traditional steel fencing unsuitable, GRP fencing offers the ideal solution. CLD’s FibreSafe system provides a non-conductive fence with tested strength, long-term durability, and minimal maintenance, making it the go-to perimeter choice for critical infrastructure and high-risk electrical or research sites across the U.S.
As energy, data, and research facilities become more complex, the materials surrounding them must meet equally complex standards. Traditional metal fencing, while strong and secure, can introduce electrical conductivity, magnetic interference, and long-term corrosion.
That’s where GRP fencing comes in. Standing for Glass Reinforced Plastic, GRP combines the rigidity of steel with the insulation and chemical resistance of advanced polymers. CLD’s FibreSafe range was engineered for environments that can’t risk electrical transmission or corrosion, delivering safety without compromising performance.
Unlike metal mesh, non-conductive fences built from GRP don’t transmit electrical current. This single property opens a range of applications where personnel, equipment, or sensitive instruments must be protected from potential arcing or electrical interference.
When specified as part of a perimeter design, FibreSafe helps maintain safe working zones around substations, power facilities, and industrial research areas. The material also remains stable in humid or saline environments, where steel or aluminum systems would typically degrade.
For sites that need a security rated GRP solution with no metal content, CLD Physical Security Systems delivers certified materials, engineered for American conditions and standards.
GRP fencing excels where electrical isolation, corrosion resistance, or low maintenance are priorities. Typical use cases include:
These environments demand a perimeter that performs quietly in the background, something GRP fencing achieves exceptionally well.
One of the most common misconceptions about GRP is that it sacrifices strength for non-conductivity. In reality, CLD’s FibreSafe systems are structurally tested to withstand impact and environmental stress comparable to steel frameworks.
Each component is reinforced with woven glass fiber and engineered to resist bending, UV degradation, and environmental wear. Panels are modular and lightweight, which simplifies logistics, installation, and retrofitting onto existing perimeters.
This makes FibreSafe a preferred choice for facilities that demand a precision perimeter, a fence that performs with accuracy, repeatability, and minimal risk across decades of service.
Because GRP does not corrode or require coatings, it offers long-term cost efficiency compared to traditional metals. There’s no need for periodic galvanizing, repainting, or grounding inspections, and its inherent chemical resistance means it remains visually and structurally stable over time.
For facility managers, that translates to reduced operational downtime and predictable lifecycle costs, both major advantages for large-scale industrial or energy operations.
GRP fences don’t exist in isolation. Many U.S. sites integrate non-conductive fencing with security rated steel or crash-rated systems for layered protection. CLD’s modular approach allows FibreSafe sections to coexist with traditional mesh or vehicle barriers within a single perimeter layout.
This mixed-material strategy helps specifiers meet strict security requirements while also protecting sensitive areas from conductivity or interference. CLD’s technical team supports American clients with CAD models, specification guidance, and field-tested installation methods for hybrid perimeters.
CLD has been developing security fencing for over 50 years, combining British engineering with proven performance across the U.S. and global markets. The FibreSafe GRP line reflects that innovation, delivering a non-conductive fence that meets the same security, modularity, and durability standards as CLD’s steel systems.
When specifying for critical infrastructure or environments with electrical hazards, CLD Physical Security Systems provides both the expertise and product range to design a compliant, long-lasting perimeter.
GRP fencing isn’t just an alternative, it’s the standard for environments where conductivity and corrosion can’t be tolerated. With FibreSafe, CLD brings together electrical safety, durability, and design precision in one proven solution.
