When Should You Use 3mm Artificial Grass Pins?

3mm U-pins are best suited for:

  • Softer soil conditions
  • Sand or granite dust bases
  • Areas without heavy compacted sub-base
  • Lighter domestic installations
  • Smaller garden projects

If your ground is firm but not heavily compacted, 3mm pins provide secure anchoring without excessive force required during installation.

Product Specification

  • Type: Galvanised steel U-pin
  • Pack Size: 100 pins
  • Suitable for: Softer ground & light domestic installs
  • Corrosion Resistant: Yes (galvanised finish)

How Many 3mm Pins Do I Need?

As a general installation guide:

  • Perimeter: 1 pin every 200mm
  • Internal area: 1 pin per m²
  • Joints: 1 pin every 200mm along seams

For a typical 30–40m² lawn, one pack is usually sufficient. Larger areas may require multiple packs.

3mm vs 3.6mm vs 4mm – Which Should I Choose?

  • 3mm → Softer ground & lighter installs
  • 3.6mm → Most popular for standard domestic sub-base
  • 4mm → Hard ground & maximum holding strength

If your sub-base is compacted MOT Type 1, 3.6mm may be more suitable.

Will These Rust?

No. These pins are galvanised to resist corrosion and are designed for long-term use in outdoor environments.

Installation Tips

  1. Lay the artificial grass in position and secure one end first.
  2. Tension and stretch the artificial grass using a carpet kicker for a tight, professional finish.
  3. Work around the perimeter at 200mm intervals. Take care not to trap grass fibres when driving the pins into the ground.
  4. Add internal stabilising pins.
  5. Brush fibres upright to conceal pin heads.

When installed correctly, pins remain discreet and virtually invisible.
