Steel trunkings

Steel trunkings, also known as steel cable trays, wire mesh trays, or steel raceways, are rigid metallic containment systems designed for the mechanical protection and routing of electrical cables, power conductors, and data communication lines in industrial and commercial installations. These systems are typically manufactured from galvanized steel, stainless steel, or pre-painted steel, offering high mechanical strength and resistance to corrosion, impact, and fire. Steel trunkings are available in various cross-sectional profiles, including perforated, solid, or ladder-type, and are supplied with a full range of accessories such as covers, couplings, brackets, and supports. They are designed to accommodate multiple cable layers and are rated for specific load capacities, often expressed in terms of cable fill ratio and maximum span length. The systems comply with international standards like IEC 61537, EN 50085, or NEMA VE 1, ensuring safe and reliable cable management in harsh environments.

Steel trunkings are widely deployed in industrial automation plants, power generation facilities, oil and gas refineries, chemical processing units, data centers, and commercial buildings. They are used for routing power cables, control cables, instrumentation cables, and fiber optic lines within electrical rooms, switchgear rooms, motor control centers, and along production lines. In heavy industries, steel trunkings provide robust protection against mechanical damage, dust, moisture, and electromagnetic interference (EMI). They are also essential in hazardous areas where fire resistance and non-propagating characteristics are required, such as in Zone 1 or Zone 2 classified locations. Additionally, they are used in infrastructure projects like tunnels, airports, and metro systems for secure cable management.

Key subcategories within steel trunkings include perforated cable trays, solid bottom cable trays, ladder-type cable trays, and wire mesh cable trays. Main article codes often follow a structured format, such as ST-100-3000-GS, where 'ST' denotes steel trunking, '100' indicates width in mm, '3000' represents length in mm, and 'GS' stands for galvanized steel. Other common codes include CT-200-6000-SS for stainless steel trays or LT-150-3000-PP for pre-painted versions. Accessories like covers (e.g., CV-100-GS), couplings (e.g., CP-100-GS), and brackets (e.g., BK-100-GS) are also available to complete the installation. These products are typically stocked in standard lengths of 2m, 3m, or 6m, with custom lengths available upon request.
