3D PANEL FENCE WEIGHT PER M²
V-pressed 3D panels weigh 3–8% more than flat 2D panels because of the bends. Enter the vertical and horizontal wire diameters, mesh openings and bend depth + pitch — kg/m², panel mass and total tonnage come out instantly.
Inputs
Formula
k = 2 · √((p/2)² + h²) / p (curve factor) m/m² = k · ρ_v + ρ_h (kg/m²)
p: bend pitch (mm). h: bend depth (mm). k: factor by which a single bend stretches the vertical wire — typically 1.03–1.08. ρ_v: vertical-wire kg/m² contribution as in flat 2D, ρ_h: horizontal-wire contribution. Only verticals get k; horizontals stay flat. Larger depth or smaller pitch raises k.

Quick reference — 3D panel curve factors
Curve factors for common V-press combinations and the resulting mass per m² for a 5 mm vertical / 5 mm horizontal panel with 200 × 50 mm mesh. Production tolerance ±3%.
| Bend (h × p) | Factor k | kg/m² (5×5, 200×50) |
|---|---|---|
| 25 × 250 mm | 1.020 | 3.52 |
| 25 × 200 mm | 1.031 | 3.54 |
| 30 × 200 mm | 1.044 | 3.58 |
| 30 × 150 mm | 1.077 | 3.66 |
| 35 × 200 mm | 1.060 | 3.62 |
| 40 × 200 mm | 1.077 | 3.66 |
Production tolerance
When the bends are pressed, vertical wire length deviates by ±1.5 mm and bend depth by ±1 mm. Apply ±3% tolerance to per-m² mass. For large orders, the factory weighbridge ticket rules.
Surface coating
Standard 3D panel: electro-galvanised + polyester powder coating (RAL 6005 green, 7016 anthracite, 9005 black). Coating adds ~0.15–0.25 kg/m². For corrosive sites use heavy galvanised (80 μm) + powder topcoat as a duplex system.
