Swedish Anti-corrosion Cable Tray Fiberglass Specifications

Swedish anti-corrosion fiberglass cable trays are made from corrosion-resistant FRP/GRP composites, offering high strength, lightweight construction, and durability in harsh environments.

Material and Construction

These cable trays are manufactured from fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), using pultrusion technology to create strong, uniform profiles . The trays are non-conductive, non-magnetic, and corrosion-resistant, making them ideal for offshore, chemical, and industrial applications . Pultrusion ensures a resin-rich surface that provides superior corrosion resistance and UV protection . Common resins include polyester, vinylester, and acrylic, with custom formulations available for specific project requirements .

Mechanical Properties

Fiberglass cable trays offer a high strength-to-weight ratio, often surpassing steel in pound-for-pound strength while weighing only about one-third as much . They are designed to maximize loading capacity while reducing weight, which improves safety during installation and lowers transportation costs . The trays are tested according to ASTM standards for flame resistance (ASTM E-84, Class 1) and self-extinguishing properties (ASTM D-635), .

Dimensions and Configurations

Standard heights typically include 50 mm, 80 mm, 100 mm, 125 mm, and 150 mm, with widths ranging from 100 mm to 1200 mm and lengths of 3000 mm or 6000 mm . Configurations include straight sections, horizontal tees, horizontal crosses, vertical tees, reducers, and risers, with radii options of 300, 600, and 900 mm . Accessories such as covers, cover clips, fixing clamps, and smart jigs are available in FRP or stainless steel for secure installation .

Performance and Applications

Fiberglass trays are resistant to rust, chemical attack, and extreme environmental conditions, making them suitable for offshore platforms, chemical plants, refineries, water treatment facilities, and laboratories . They are non-conductive, reducing electrical hazards, and transparent to radio waves, radar, and microwaves, which is critical in sensitive instrumentation areas . The lightweight design also enhances HSE (Health, Safety, and Environment) performance during lifting and installation .

Summary

Swedish anti-corrosion fiberglass cable trays combine durability, corrosion resistance, and high load capacity with lightweight, non-conductive construction. They are available in multiple resin types, heights, widths, and configurations, making them adaptable for harsh industrial and offshore environments while reducing maintenance and lifecycle costs .
