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.

Weight = Volume × 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:

Steel: 7850 kg/m³
Aluminum: 2700 kg/m³

Knowing the correct density is crucial for accurate load calculations and support planning.

Key Factors

Several dimensions affect the final weight:

Width & Height
Thickness (Gauge)

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.

Target Load: 15 kg/m

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):

0.0005m² × 7850 kg/m³ = 3.92 kg/m

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)

Design Load = 18.92 × 1.5 = 28.38 kg/m

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).
