Frequently Asked Questions

What is corten steel?
Corten (weathering steel) is a special alloy that forms a stable, protective rust layer when exposed to the elements. This natural patina prevents further corrosion and gives the edging its signature rustic appearance.

How long does it take for the rust patina to develop?
The patina typically develops over several weeks to months depending on weather exposure. The edging is functional immediately upon installation.

Can I connect Ridgidline to Flexline?
Yes, Ridgidline and Flexline panels can be connected using Straightcurve joining hardware, allowing you to combine straight and curved sections in the same garden design.

Is it easy to install?
Yes. Ridgidline is designed for easy DIY installation on soft ground, hard surfaces and even concrete. Smaller heights simply peg into the ground, while taller panels use pins for stability.
