Weight table of hot-dip galvanized cable trays

The weight per meter of hot-dip galvanized cable trays varies by series, width, and perforation, typically ranging from 5 to 25 kg/m depending on the tray type and thickness.Factors Affecting WeightTray Series and Size: Common series include 40, 50, 60, 75, and 100, with higher series numbers generally indicating larger and heavier trays .Perforation Type: Perforated trays are slightly lighter than solid trays due to the material removed for holes, but the difference is usually minor compared to overall tray thickness .Material Thickness: Hot-dip galvanized steel thickness directly affects weight. Standard thicknesses range from 1.5 mm to 3 mm for heavy-duty applications .Width of Tray: Wider trays carry more material and therefore weigh more per meter. Typical widths range from 100 mm to 600 mm or more .Approximate Weight Ranges40 Series Perforated: ~5–8 kg/m50 Series Perforated: ~7–10 kg/m60 Series Perforated: ~10–15 kg/m75 Series Perforated: ~15–20 kg/m100 Series Solid or Perforated: ~20–25 kg/m These values are approximate and can vary ±10% depending on manufacturer tolerances, coating thickness, and specific design .Practical ConsiderationsStandard cable tray lengths are 3 meters, so total weight can be estimated by multiplying the weight per meter by 3 .For structural calculations, always consider the maximum expected weight including cables and any environmental loads.Hot-dip galvanization adds a thin zinc coating, which slightly increases the weight compared to pre-galvanized trays . By consulting the manufacturer's datasheet for the specific series and width, you can obtain the exact weight per meter for precise engineering calculations.
