📋 Fence Types Explained

🔒 Privacy Fence: Uses wide boards (typically 150mm) placed tightly together with no gaps, standing 1.8m or taller. Completely blocks the view — ideal for backyards and pool enclosures.

🏡 Picket Fence: Uses narrower pickets (typically 90mm) with 50-70mm gaps between them, usually around 1.2m tall. Offers both aesthetics and airflow — great for front yards.

⛓️ Chain-link Fence: Uses metal mesh sold by the roll (15-25m per roll). The most economical option, requires tension bars and ties. Best for large areas and industrial sites.

💡 Installation Tips

• Hole depth: Should be 1/3 to 1/2 of the post's above-ground height, and must extend below the local frost line
• Post spacing: Keep it under 2.4m to prevent rails from sagging over time
• Concrete: Each post needs roughly 1-2 bags of 40kg concrete, depending on hole dimensions
• Buy 10% extra: Always order 10% more material for waste and cutting errors
• Underground utilities: Always call your local utility company before digging
• Corners & gates: Each corner and gate opening needs additional posts
