Technical Specifications for Wire Mesh Cable Trays

Wire mesh cable tray technical requirements are crucial for the success of cable management and wiring systems. Our wire mesh cable trays undergo strict quality control and testing to ensure their reliability under various environmental conditions. Whether in industrial facilities, commercial buildings, or data centers, our wire mesh cable trays provide stable load-bearing capacity.

Item Description
Electrogalvanized Surface Treatment Requirements
  • Surface electrogalvanized with blue-white zinc, zinc layer thickness 8–12 μm
  • According to GB/T 9286-1998 Paints And Varnishes-Cross Cut Test For Films, the coating should be 100% adhered.
  • The main material shall pass the 48 h neutral salt spray test according to GB/T 2423.17-2008.
  • Electrogalvanized structural parts should not expose the base material. The coating should be smooth, uniform, and dense, without missing plating, bubbles, peeling, spots, or protrusions. There should be no visually discernible color differences or marks.

Notes:
  • The average load-bearing capacity per meter and span are related to cable tray width, height, wire diameter, cross-sectional dimensions, and other parameters. The above load-bearing data is for reference and can be adjusted according to the actual project condition.
  • The deflection d of the cable tray after carrying the load should be ≤ P/200 (P–span). For example, when the span is 2 m, the deformation within the 2 m span under full load should be d ≤ 2000/200 = 10 mm.
Electrical Continuity Test Measure the voltage drop V1 between two points at a distance D = 500 mm on the straight section of the wire mesh cable tray, and then measure the voltage drop V2 between two points 50 mm on each side of the joint connecting the two straight sections. Calculate the resistance values R1 and R2 based on the current and voltages V1 and V2. The test results should satisfy R1/D ≤ 5 mΩ/m, R2 < 50 mΩ.
