How to Calculate Cable Tray Weight
General Formula
To calculate the weight of a cable tray, you need to determine the volume of material used and multiply it by the material's density.
For most trays, this involves calculating the cross-sectional area of the solid parts (side rails, rungs, or bottom) and multiplying by length.
Material Density
The material type significantly impacts the total weight. Common densities include:
Knowing the correct density is crucial for accurate load calculations and support planning.
Key Factors
Several dimensions affect the final weight:
Greater thickness increases weight linearly. Perforated trays weigh less than solid bottom trays due to material removal.
Site Scenario
Project: Commercial Office Riser
Requirement: Support 20 data cables + 5 power cables over a 50m vertical run.
The engineer must verify if a standard 300mm x 50mm Steel Perforated Tray is sufficient.
Step-by-Step Calculation
Step 1: Calculate Tray Weight
Volume = Area × Length. For 1m of 300x50mm steel (approx area 0.0005m²):
Step 2: Add Cable Load (15 kg/m)
Total Load = 3.92 + 15 = 18.92 kg/m
Final Verification
Step 3: Safety Factor (1.5x)
Conclusion: The heavy-duty steel tray (rated for 50 kg/m) is Safe to use.

Cable Tray Weight FAQs
How to calculate the weight of a cable tray?
Calculate the volume of the tray material (Cross-sectional Area × Length) and multiply by the material density (e.g., 7850 kg/m³ for steel).
How much does a cable tray weigh?
Weight varies by size and material. A typical 300mm wide steel ladder tray weighs approximately 4-6 kg/m, while a similar aluminum tray weighs about 1.5-2.5 kg/m.
How to calculate cable weight per meter in kg?
For cables, weight per meter is usually provided by the manufacturer. If estimating from dimensions: Weight = (Area × Length × Density). Ensure units are consistent (e.g., meters and kg/m³).
What is the price of 50 * 50 cable tray?
Prices fluctuate based on raw material costs (steel/aluminum) and region. Please consult local suppliers for current pricing per meter or length.
What is the formula for weight in KG?
The general formula for weight is: Weight (kg) = Volume (m³) × Density (kg/m³).
