High alloy cable trays are available in stainless steel (304/316) and aluminum alloys (AA1100, AA8011, A3105), with a wide range of straight sections, fittings, and accessories.

Material Types and Standards

High alloy cable trays are typically manufactured from:

• Stainless Steel: Grades 304 and 316, compliant with BSEN 10088-2, offering excellent corrosion resistance for industrial and outdoor applications .
• Aluminum Alloy: Grades AA1100, AA8011, and A3105, conforming to BSEN 485-1, providing lightweight, durable, and corrosion-resistant solutions .
• Coatings: Some trays include hot-dip galvanization or powder coatings to enhance durability and meet ASTM A123/ISO 1461 standards .

Tray Types

High alloy cable trays are available in multiple configurations:

• Ladder Type: Open rungs for maximum ventilation and heat dissipation.
• Perforated Tray: Solid bottom with perforations for cable support and airflow.
• Solid Bottom Tray: Provides full protection for sensitive cables.
• Wire Mesh Tray: Flexible, lightweight, and easy to install in complex layouts.

Standard Sizes and Dimensions

• Widths: Typically range from 50 mm to 600 mm.
• Heights: Commonly 50 mm, 70 mm, 100 mm, 120 mm.
• Lengths: Standard straight sections are available in 2 m, 3 m, and 6 m lengths, with custom lengths on request .

Fittings and Accessories

High alloy cable trays include a comprehensive set of fittings and accessories:

• Elbows: Horizontal and vertical, inside and outside.
• Tees and Crosses: For branching cable runs.
• Reducers: To transition between different tray widths.
• Covers and Clips: For protection and securing cables.
• Coupler Plates and Fasteners: For joining sections and ensuring structural integrity .
