Technical Specifications
The wire mesh cable tray system is constructed from high-tensile steel wire using an automatic welding process that forms a grid structure with consistent mesh openings. The standard configuration uses longitudinal wires (running parallel to tray length) welded to transverse U-shaped wires at regular intervals, creating a rigid yet open cage architecture.

    Nominal widths: 50 mm, 100 mm, 150 mm, 200 mm, 300 mm, 400 mm, 500 mm, 600 mm
    Standard lengths: 3,000 mm (other lengths available on request)
    Sidewall heights: 35 mm, 55 mm, 80 mm, 105 mm
    Longitudinal wire diameter: 3.8 mm to 6.0 mm depending on load class
    Transverse wire diameter: 4.0 mm to 5.0 mm (U-form)
    Mesh grid size (longitudinal × transverse): 50 mm × 100 mm (standard), 25 mm × 100 mm (high-density variant)
    Material: Electro-galvanised steel (SENDZIMIR process), hot-dip galvanised steel (to ISO 1461), stainless steel grades 304 and 316L
    Zinc coating mass (electro-galvanised): ≥12 μm per side, tested per IEC 61537 Clause 10
    Zinc coating mass (hot-dip galvanised): ≥45 μm (average), tested per ISO 1461
    Safe working load (SWL): 20 kg/m to 120 kg/m depending on width, wire gauge, and support span (tested per IEC 61537 Clause 8)
    Safety factor: 1.7 minimum across all load classes
    Operating temperature range: -40 °C to +150 °C (stainless steel); -20 °C to +120 °C (galvanised)
    Electrical continuity: ≤50 mΩ resistance across joints when assembled with recommended connectors, verified per IEC 61537 Clause 11
    Minimum bend radius compatibility: ≥100 mm with factory-formed radius bends and T-sections


Standards Compliance
Chinne Electric wire mesh cable trays are designed, manufactured, and tested to meet the requirements of IEC 61537: Cable management — Cable tray systems and cable ladder systems. This international standard governs mechanical strength under uniformly distributed and concentrated loads, corrosion resistance of metallic coatings, electrical continuity for protective earth bonding, and dimensional tolerances. Independent type-test reports are available on request. Hot-dip galvanised finishes additionally comply with ISO 1461: Hot dip galvanized coatings on fabricated iron and steel articles for coating thickness and adhesion. Where specified for fire-rated installations, the system supports compliance with IEC 60331 circuit integrity requirements when used in conjunction with fire-resistant cable fixings.

Applications
The open-grid structure of the wire mesh cable tray permits cable exits in any direction through the mesh openings without cutting or drilling, making the system suited to installations where cable routing changes frequently or where dense cable populations require ongoing access. Typical deployment environments include:

    Data centres: Overhead containment beneath raised access floors or in suspended ceiling voids for segregated power and data cable pathways; the open mesh promotes passive heat dissipation from bundled cables.
    Commercial buildings: Distribution above suspended ceilings for lighting, HVAC control, security, and structured cabling backbone routes.
    Manufacturing plants: Machine-level distribution networks, control panel interconnections, and production line cable management where vibration resistance and accessibility are required.
    Infrastructure projects: Tunnel cable containment, rail signalling pathways, and utility corridors where corrosion resistance (particularly stainless steel or hot-dip galvanised finishes) is critical.
    Telecommunications facilities: Exchange and headend cable management with high-density copper and fibre optic cable segregation.


FAQ

What is the difference between electro-galvanised and hot-dip galvanised finish for wire mesh cable tray, and which standard applies?
Electro-galvanised finish applies a zinc coating through an electrolytic process, yielding a smooth, uniform surface with a typical coating thickness of ≥12 μm per side. This finish is suitable for indoor environments with low humidity and negligible corrosive exposure. Hot-dip galvanised finish, applied by immersion in molten zinc in accordance with ISO 1461, produces a thicker coating (≥45 μm average) with a metallurgical bond to the steel substrate. It provides significantly greater corrosion resistance and is specified for outdoor installations, high-humidity environments, and areas subject to intermittent condensation. Both finishes are verified for corrosion resistance under IEC 61537 Clause 10.

How are T-offs and cable exits achieved on a wire mesh tray without compromising structural integrity?
Cable exits are made by cutting individual transverse wires between the longitudinal wires at the required location using wire cutters; the longitudinal wires remain intact and continue to carry the structural load. This creates an opening in the mesh through which cables can exit downward, left, or right. Because the cage structure distributes load across multiple longitudinal wires, removing a short section of transverse wire has negligible effect on the SWL of the tray provided the cut is made cleanly and no longitudinal wires are severed. For larger T-off branches, factory-fabricated T-sections, reducers, and radius bends are available that maintain full load rating and electrical continuity.

What support spacing is required to achieve the published safe working load?
Safe working load values per IEC 61537 are established through type testing at defined support spans. The standard support spacing for wire mesh cable tray is 1,500 mm centre-to-centre. At this span, the published SWL is achieved. Reducing the support spacing to 1,000 mm or 750 mm increases the load capacity proportionally; conversely, spans exceeding 1,500 mm reduce the allowable load. Joint connectors (splice kits) must be positioned no further than 200 mm from a support point to maintain continuity of the load path. Refer to the project-specific loading schedule or contact Chinne Electric technical support for load/span tables derived from IEC 61537 Clause 8 testing.
