| Basic Type |
Type |
Perforated Cable Tray / Ventilated Cable Tray |
Also known as channel cable tray |
| Width |
Width |
50 – 1,200 mm |
Common widths: 50, 100, 150, 200, 300, 400, 450, 500, 600, 700, 800, 900, 1000, 1200 mm |
| Side Rail Height |
Side Rail Height |
25 – 300 mm |
Typical heights: 25, 30, 40, 50, 60, 75, 100, 110, 150, 200, 250, 300 mm |
| Standard Length |
Length |
2,000 mm / 3,000 mm / 6,000 mm |
Common: 2m, 3m, 6m; also 10 ft (3050 mm); custom lengths available |
| Material Thickness |
Thickness (Al) |
0.6 – 3.0 mm |
1.0 mm for 50–100 mm width; 1.5 mm for 200–500 mm; 2.0 mm for 600–700 mm; 2.5 mm for 800–1000 mm. Equivalent SWG: 18, 16, 14 |
| Material Grade |
Alloy Grade |
6063-T6, 6061, 6005A |
6063-T6 is the most common – good strength, lightweight, excellent corrosion resistance |
| Surface Finish |
Finish |
Anodised / Powder coated / Mill finish |
Natural oxide film provides self-healing; additional coating is optional |
| Perforation Pattern |
Hole Shape |
Round / Elliptical / Slotted |
e.g., 2.25” round holes; or slotted 7×32 mm, 7×20 mm |
| Open Area |
Perforation Ratio |
15 – 30% (typical), up to 30–50% max |
Standard design 15–30%; high ventilation applications (e.g., data centres) 30–50% |
| Load Class (IEC 61537) |
Load Rating |
Class A: ≤50 kg/m |
Perforated trays typically lower load capacity than ladder trays; suitable for instrumentation, data cables |
| Class B: ≤100 kg/m |
| Class C: ≤150 kg/m |
| Class D: ≤200 kg/m |
| Safe Working Load (SWL) |
SWL |
25 – 75 kg/m @ typical span |
About 50–60% of the ladder-type tray of the same dimensions, depending on support spacing |
| Maximum Support Span |
Span Length |
≤3.0 – 6.0 m |
Perforated trays have shorter max spans than ladder trays; they can be increased by thicker material |
| Thermal Conductivity |
Thermal Conductivity |
237 W/(m·K) |
~5 times higher than steel – excellent heat dissipation |
| Weight |
Weight (approx.) |
4 – 8 kg/m (depending on size) |
Example: 110 mm × 200 mm → ~4.3 kg/m; 110 mm × 600 mm → ~8.21 kg/m. About 1/3 of the weight of steel trays |
| Operating Temperature |
Temperature Range |
–40°C to +120°C |
Stable mechanical properties; specific range depends on alloy and finish |
