Non-magnetic cable trays

Non-magnetic cable trays are typically made from fiberglass-reinforced plastic (FRP) or other non-metallic materials, offering corrosion resistance, lightweight construction, and high strength-to-weight ratios.Overview of Non-Magnetic Cable TraysNon-magnetic cable trays are designed to avoid interference with sensitive electrical or electronic systems. They are commonly used in industries such as petroleum, mining, fertilizer, offshore oil and gas, and medical facilities. These trays are non-conductive, corrosion-resistant, and lightweight, while still providing load capacities comparable to steel trays .Common Models and TypesFiberglass-Reinforced Plastic (FRP) TraysMade using pultrusion technology, which ensures a resin-rich surface for UV resistance and corrosion protection.Meet ASTM E-84 Class 1 flame rating and ASTM D-635 self-extinguishing requirements.Examples include T&B nonmetallic cable trays suitable for harsh offshore and industrial environments .Channel Cable Trays (GRP)Offered by manufacturers like Eaton, these trays are available in multiple CAD and BIM formats for design integration.Ideal for customized layouts and complex installations .Swifts Cable Tray SystemModular, slot-patterned trays with four depth options: light duty (12–18mm), medium duty (25mm), heavy duty (50mm), and extra heavy duty (80mm).Features fast-fit installation with Swiftclip connectors, reducing installation time and labor costs.Suitable for both internal and external environments .Nonmetallic Pultruded TraysLightweight yet strong, these trays are non-magnetic and corrosion-resistant, making them ideal for saltwater, chemical, or outdoor exposure.Can be used in petroleum, mining, and fertilizer industries where environmental conditions are harsh .Key Features to ConsiderMaterial: FRP or other non-metallic composites for non-magnetic properties.Load Capacity: Comparable to steel trays, despite lighter weight.Corrosion Resistance: Suitable for chemical, saltwater, or outdoor exposure.Flame Rating: Compliance with ASTM standards for safety.Installation: Modular systems with fast-fit connectors reduce labor and installation time.Design Flexibility: Available in multiple depths and widths to accommodate different cable types and routing requirements. Non-magnetic cable trays provide a durable, safe, and interference-free solution for sensitive electrical installations, combining the benefits of lightweight construction with high strength and corrosion resistance. Manufacturers like ABB, Eaton, Atkore, and Legrand offer a variety of models to suit different industrial and commercial applications .
