Fiberglass cable trays (FRP/GRP) in North Africa are lightweight, corrosion-resistant, non-conductive, and fire-retardant systems designed for harsh industrial environments.

Material and Construction

Fiberglass cable trays are made from Fiberglass Reinforced Plastic (FRP) or Glass Reinforced Plastic (GRP), combining continuous longitudinal rovings, filament mats, and resin to achieve high strength and stiffness . They are available in polyester or vinylester resin systems, with surface veils applied during pultrusion to enhance corrosion resistance and UV protection . The trays are non-conductive, non-magnetic, and transparent to radio waves, making them suitable for sensitive electrical and instrumentation installations .

Mechanical Properties

• Load Capacity: Comparable to steel while being significantly lighter, typically 1/3 the weight of steel trays .
• Side Rail Thickness: Standard FRP side rails range from 4.5 mm to 6 mm, depending on the series (LM, LMH, LH) and load requirements .
• Strength and Stiffness: Pultruded FRP provides high modulus of elasticity and returns to its original shape under allowable loads without permanent deflection .
• Durability: Resistant to rust, peeling, or flaking, with extremely long service life and minimal maintenance .

Environmental Resistance

• Corrosion Resistance: Excellent resistance to acids, bases, and chemical exposure, suitable for chemical plants, oil refineries, and offshore platforms .
• UV Protection: Integral UV inhibitors and synthetic surface veils prevent degradation from sunlight .
• Fire Retardancy: Compliant with ASTM E-84, Class 1 Flame Rating, and BS 476 standards, self-extinguishing per ASTM D-635 .
• Temperature Stability: Minimal expansion under heat and retention of mechanical properties at elevated temperatures .

Design and Installation

• Tray Types: Available in solid-bottom, perforated, and ladder-style designs to accommodate low-voltage, telecommunication, and fiber-optic cables .
• Widths and Heights: Multiple sizes to optimize loading space and cable management .
• Accessories: Full range of fittings, splices, covers, brackets, and support channels (cantilever and trapeze) for flexible installation .
• Ease of Handling: Lightweight construction allows for easier cutting, handling, and installation, reducing labor and transportation costs .

Applications

Fiberglass cable trays are ideal for harsh and corrosive environments in North Africa, including:

• Oil and gas facilities
• Petrochemical plants
• Water treatment plants
• Offshore platforms
• Industrial manufacturing and mining operations

Summary

FRP/GRP cable trays in North Africa provide a high-strength, lightweight, and corrosion-resistant solution for electrical and instrumentation cable management. They combine mechanical durability, fire safety, UV protection, and chemical resistance, making them suitable for both onshore and offshore industrial applications while reducing maintenance and installation costs .
