Swedish Polymer Cable Tray Specifications

Swedish polymer cable trays are designed for corrosion resistance, lightweight handling, and compliance with European safety standards, suitable for industrial and commercial installations.Material and ConstructionSwedish polymer cable trays are typically made from high-strength polyester resin or vinyl ester, produced using a pultrusion process to ensure uniform strength and durability . This construction provides excellent corrosion resistance, making them suitable for harsh environments where metal trays may degrade, such as chemical plants or outdoor installations . The trays are lightweight yet strong, offering a high resistance-to-weight ratio compared to steel alternatives .Dimensions and Load RatingsPolymer cable trays in Sweden are available in standard lengths of 2–3 meters, with customizable widths and heights depending on project requirements . Rung spacing is generally 150–230 mm, which supports proper cable separation and minimizes bending stress on cables . Load ratings vary by manufacturer and tray type, but polymer trays are engineered to handle typical industrial cable loads while maintaining structural integrity over long spans .Environmental and Safety StandardsThese trays comply with European directives and are often CE marked, indicating adherence to safety, mechanical, and electrical standards . They are suitable for environmental classes up to C2, covering indoor industrial, office, and school installations . Polymer trays are resistant to UV exposure, moisture, and chemical corrosion, and can be used in areas where metal trays would require additional protective coatings .Installation and AccessoriesInstallation is simplified due to the lightweight nature of polymer trays. Standard mounting uses M8 bolts and minimal tools, often just a bolt cutter and a 13 mm wrench . Accessories include angle brackets, spacer rails, and junction boxes, allowing flexible configurations for walls, floors, or ceilings . Trays can be cut, bent, and customized on-site to fit unique project layouts .ApplicationsSwedish polymer cable trays are ideal for:Industrial facilities with corrosive environmentsCommercial buildings requiring lightweight, easy-to-install systemsOutdoor or humid locations where metal trays may corrodeProjects needing flexible, customizable cable management solutions SummarySwedish polymer cable trays combine durability, corrosion resistance, and compliance with European safety standards. They are lightweight, customizable, and suitable for a wide range of industrial and commercial applications, with flexible installation options and a variety of accessories to meet project-specific requirements .
