Bending company's 50mm galvanised cable tray specification& positioning
The core parameters and application positioning of the "50mm Galvanized Cable Tray" are summarized in the table below:
| Parameter Dimension | Typical Specification Description | Application Characteristic Interpretation |
|---|---|---|
| Channel Height | 50mm (Internal clear height) | Determines its suitability for cables with smaller outer diameters (e.g., control cables, instrument signal cables, small-to-medium specification power cables). |
| Material Thickness | National standard requirements: side/base plate typically ≥1.0mm (specifics depend on load class). | Provides basic structural support, falling into the light to medium-duty load category, distinct from "heavy-duty trays." |
| Width Series | Common: 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, etc. | When selecting width, ensure the total cross-sectional area of cables does not exceed 40%-50% of the tray's internal cross-sectional area. |
| Surface Treatment | Hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing (zinc coating ≥55μm) offers better corrosion resistance and is preferred for outdoor and industrial environme nts. |
The zinc coating provides basic rust protection, suitable for general indoor and dry outdoor environments. For high-corrosion areas like chemical plants or coastal regions, assessment is needed, or stainless steel should be considered. |
| Load & Span | Safe working load is typically < 100 kg/m, with support spans generally between 1.5 to 3 meters. | Spans must be strictly calculated based on actual cable weight to prevent excessive sagging. |
Bending company's 50mm galvanised cable tray Primary Application Scenarios
Due to its moderate capacity and cost, the 50mm high galvanized tray is widely used in:
-
Building Electrical Systems: Horizontal and vertical routing for lighting, socket outlets, and low-voltage (network, telephone) lines in office buildings, shopping malls, and residential complexes.
-
Industrial Control: Tray systems for control cables, instrument signal cables, and low-voltage power lines in factory production lines and equipment rooms.
-
Small Equipment Rooms: Cable convergence and management above or below network cabinets.
-
Lightweight Equipment Floors: Cable routing in equipment mezzanines with low space and load requirements.
Bending company's 50mm galvanised cable tray Important Selection & Installation Notes
To ensure safety and reliability, pay attention to the following during selection and installation:
-
Accurate Load Calculation: Always calculate the total weight of all cables and determine appropriate support spacing based on the supplier's load-span curve. Avoid tray deformation due to overload.
-
Distinguish "Heavy-Duty" vs. "General Purpose": A 50mm high tray typically does not fall into the "heavy-duty" category. For heavier cables or longer span requirements, choose a model with higher side walls, thicker plates, and stiffeners, and request load test reports.
-
Environmental Suitability: In damp or chemically aggressive environments, verify if the hot-dip galvanizing thickness is sufficient, or consider trays with galvanizing plus powder coating ("zinc + plastic") for better protection.
-
System Integrity: Ensure the use of original or compatible connection plates, screws, and bonding jumpers to guarantee electrical continuity and structural strength.
Bending company's 50mm galvanised cable tray Summary:
The "50mm Galvanized Cable Tray" is a cost-effective, general-purpose cable routing solution. The key to its successful application is: precisely matching the cable scale, strictly controlling support spans, and ensuring it is used within its designed environmental conditions. For more demanding loads or environments, higher-grade products should be considered.
