Selecting the right tubing tray (often referred to as a cable tray) is less about picking a product and more about making a series of smart decisions. If you follow the logic below, you can quickly narrow down the best option for your wiring system.
Step 1: Define What You Are Carrying
Start by answering one basic question: what kind of cables will run through the tray?
Heavy power cables
Control and instrumentation wiring
Data or communication cables
Power cables typically need stronger support and better heat dissipation, while data cables benefit from easy access and organized routing. Mixing cable types may require dividers or separate trays to reduce interference.
Step 2: Estimate Cable Quantity and Future Expansion
Do not size a tubing tray only for today’s needs.
Calculate the total cable cross-section
Add a safety margin for future expansion (usually 20–30%)
A well-designed tray should never be completely full. Leaving space improves airflow, reduces heat buildup, and makes maintenance easier.
Step 3: Match the Tray Design to the Application
Instead of asking “Which tray is best?”, ask “Where will it be used?”
Industrial environments with heavy cables often require ladder-type trays for strength and ventilation.
General commercial wiring usually works well with perforated trays that balance support and flexibility.
Sensitive or small cables benefit from solid-bottom trays that offer extra protection.
Offices and data centers often prefer wire mesh trays for fast installation and frequent changes.
Each design solves a different problem, so choosing the right one avoids unnecessary cost or performance issues.
Step 4: Choose the Right Material
Material selection depends heavily on the surrounding environment:
Galvanized steel for standard indoor and industrial applications
Stainless steel for corrosive, humid, or chemical environments
Aluminum for lightweight installations and ceiling-mounted systems
The wrong material can lead to corrosion, sagging, or premature replacement.
Step 5: Check Load Capacity and Support Spacing
A tubing tray is only as strong as its weakest span.
Verify the tray’s load rating (kg/m or lb/ft)
Confirm support spacing based on manufacturer recommendations
Account for both cable weight and tray self-weight
Underestimating load capacity is one of the most common causes of tray failure.
Step 6: Consider Installation and Maintenance Access
Think beyond installation day.
Ask yourself:
Will cables need to be added or removed later?
Is visual inspection important?
Will the tray be accessible after installation?
Systems that allow easy access save significant time and labor during upgrades and repairs.
Step 7: Confirm Compliance With Standards
Before finalizing your choice, ensure the tubing tray system complies with applicable standards such as:
IEC 61537
Local electrical and construction codes
Compliance ensures safety, grounding continuity, and long-term reliability.
Final Thought
Choosing the right tubing tray is not about selecting the strongest or most expensive option. It’s about matching the tray type, size, material, and design to the actual wiring conditions. When these factors align, the result is a safer, cleaner, and more adaptable wiring system.
