Frequently Asked Questions
What is the difference between Flexline and Ridgidline?
Flexline is designed for curved, flowing lines and organic shapes. Ridgidline is designed for straight lines and geometric designs. Both can be connected together in the same project.
How tight a curve can Flexline achieve?
Flexline creates smooth, gradual curves. For very tight radius turns, use the pre-formed corner pieces. The thinner profiles (75mm–150mm) flex more easily than taller panels.
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.
Is it easy to install?
Yes. Flexline is designed for easy DIY installation. Simply flex the panel into your desired curve and secure with the included spikes or pins. No special tools required.
