Fence Construction Basics
1. Posts & Spacing
Posts provide the strength. Standard spacing is 1.8m (6ft). In high-wind areas, reduce to 1.2m or 1.5m. Posts should be 98x98mm (4x4") or larger.
2. Concrete Footings
Posts should be set in concrete. A common rule is 1.5 - 2 bags (25kg) per post, buried approx 60cm deep.
3. Rails vs Panels
Stick Built: Uses horizontal rails (spikerslag) and individual vertical boards.
Great for custom slopes.
Panels: Prefabricated sections (elements). Faster to install but harder to adjust
for terrain.
Additional help & tips
Post Spacing
Standard spacing is often 1.8m (approx 6ft) to match standard board lengths or panel sizes. Closer spacing (1.2m-1.5m) makes for a stronger fence in windy areas.
