Weight of New Zealand Stainless Steel Cable Tray

Stainless steel wire mesh cable trays in New Zealand typically weigh between 5–15 kg per 3-meter section, depending on width, side height, and stainless steel grade. Material and DimensionsS. E.

P manufactures stainless steel wire mesh cable trays using 5mm T304 / ½ Hard Tempered Stainless Steel Rod, with optional Grade 316 on request. Standard tray lengths are 3 meters, with side walls of 60mm, and widths ranging from 60mm to 600mm. Smaller trays (60mm, 100mm, 150mm) can also have 30mm side walls.

The rod thickness and mesh density directly influence the tray weight.

Weight Estimation

The weight of a tray depends on its width, side wall height, and material density. Stainless steel has a density of approximately 8,000 kg/m³. Using the wire mesh construction: Narrow trays (60–150mm width, 30–60mm side walls): roughly 5–7 kg per 3-meter sectionMedium trays (200–400mm width, 60mm side walls): roughly 8–12 kg per 3-meter sectionWide trays (450–600mm width, 60mm side walls): roughly 12–15 kg per 3-meter section These values are approximate and can vary slightly depending on the exact mesh pattern, rod spacing, and grade of stainless steel used.

Accessories and Installation Considerations

All trays come with pre-drilled mounting brackets, joining plates, and fasteners. Accessories such as bends, risers, and T-sections add additional weight, which should be included in structural load calculations. For long runs, engineers often separate tray self-weight from cable fill weight to ensure accurate support design.

Summary

For planning purposes in New Zealand: Standard 3-meter stainless steel wire mesh tray: 5–15 kg depending on width and side heightMaterial: T304 stainless steel (standard), T316 optionalWidths: 60–600mm, side walls 30–60mmLength: 3 meters per section These weights provide a baseline for structural support, hangers, and load calculations, but final values should be verified against manufacturer specifications and installation conditions.
