Product Summary (150mm Ladder Tray)
150mm Width Ladder Tray is a compact and lightweight cable support system, combining the ventilation benefits of a ladder with the structural simplicity of a tray. Ideal for light to medium duty cable runs in space-constrained areas such as control panels, machine rooms, and cable trenches. Manufactured in hot-dip galvanized steel, stainless steel (304/316L), or aluminium, with customizable side rail heights and rung spacing.

Product Description
The 150mm Ladder Tray is a specialized cable management solution designed for applications where space is limited but ventilation and easy cable tying are still required. Its narrow width (150mm) makes it perfect for single or small bundles of control cables, instrumentation wiring, or light power cables.
Key features:
-
Open rung design for excellent heat dissipation and no dust/water accumulation.
-
Low side rail height for easier cable access and lower material weight.
-
Compatible with standard supports, clamps, and accessories.
Manufacturing quality:
-
Welding: Precision MIG/TIG welding with smooth, continuous seams. For aluminium: TIG welding with minimal thermal distortion.
-
Surface treatment: Hot-dip galvanized (HDG) to ISO 1461 for steel; powder coating optional; anodizing for aluminium; pickling & passivation for stainless steel.
-
Edge finishing: All cuts and edges deburred to prevent cable insulation damage.
-
Electrical continuity: Bonding jumpers available for grounding per NEC Article 392.
Customization:
-
Pre-fabricated bends, tees, reducers, risers, and drop-outs.
-
CAD drawings provided by in-house engineers for complex layouts.

2. Load Class & Typical Dimensions (Width = 150mm)
| Load Class | Side Rail Thickness (Steel) | Rung Spacing | Typical Load Capacity | Max Span |
|---|---|---|---|---|
| Light Duty (LD) | 1.2 – 1.5 mm | 300 – 400 mm | 40 – 60 kg/m | 2.0 m |
| Medium Duty (MD) | 1.5 – 2.0 mm | 225 – 300 mm | 60 – 100 kg/m | 2.5 m |

*For aluminium ladder trays, reduce load values by approximately 30% unless using 6061-T6.*
3. Quality Assurance
-
Load Testing: Vertical sag and side rail deflection tested per NEMA VE 1 / IEC 61537.
-
Material Verification: Spectrographic analysis for stainless steel and aluminium; coating thickness test for HDG (min. 65µm).
-
Welding Inspection: Visual and, if required, dye penetrant testing.
-
Corrosion Testing: Salt spray test – 500 hrs for HDG steel, 1000 hrs for 316 stainless steel.
