Why Corten Steel?

Corten steel is specifically engineered for outdoor use. Instead of deteriorating, it develops a controlled rust layer ( Patina) that acts as a protective barrier against further corrosion.

This means you get the aesthetic of rust with the strength of steel—making it one of the most reliable materials for landscaping in New Zealand conditions.

Easy Installation:

  • Hammer your edging strips into the ground, following any curves in your garden or path
  • At the straight joins, install the long pieces then hammer in a straight joiner in the middle of the join, tighten bolts supplied
  • At the corner joins, install the long pieces then hammer in a corner joiner on the corner, tighten bolts supplied
  • Enjoy your new corten garden and path edging! 

Not Sure How Much You Need?

Measure the total length of your garden edge (in metres), then divide by the length of each edging piece to calculate how many you need.

Tip: Always order slightly extra to allow for curves and adjustments.

Frequently
Asked Questions

Where is TerraEdge Made?

TerraEdge garden edging is made in our factory in Christchurch.

Can I curve TerraEdge Flexible??

Only gentle shaping is recommended. Use 100mm or 150mm edging for circles and tighter curves.

200 mm TerraEdge is not suitable for curves and circles.

How long does it take for patina to develop and will it stain my driveway or paving?

Patina starts developing in the first week of install. It's rate is faster in Autumn and winters. The development slows down in drier months.

The leeching causes stains and we recommend some gap between concrete and any corten product.

What warranty do you offer?

All TerraEdge products carry a 10 year warranty.

How long does delivery take?
