Frequently Asked Questions

What is the difference between Hardline and Ridgidline?
Hardline is specifically designed for hard surface installations such as concrete, paving and compacted ground. Ridgidline is a broader range available in heights from 75mm to 560mm for general garden edging and raised beds.

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.

Can I use Hardline on soft ground?
While Hardline is optimised for hard surfaces, it can also be installed in firm soil using the included steel spikes. For softer ground, consider the Ridgidline range.

Can I connect Hardline to other Straightcurve products?
Yes, Hardline can be connected to both Flexline and Ridgidline panels using Straightcurve joining hardware.
