Premium Steel Garden Edging. Built to Last.

Flex and Rigid are designed to be mostly buried, with just the top edge visible.
This maximises the aesthetic finish and structural strength.

Zero-Flex only requires partial burying to hide the foot.
When mostly buried on a firm base with fill near flush to the top, it is impressively strong.

Tight Curves: Flex. It flexes naturally without bending or pre-rolling.
Gentle curves & non-critical straight lines: Rigid.
Critical straight lines, immovable runs (paths, paving, formal borders): Zero-Flex.

Flex and Rigid are fully compatible within the same height, so you can combine both in a single project.

Yes.
During early patina development, run-off can leave residue on adjacent surfaces.
A slight separation between the edging and the pavers is recommended.

Once the patina is established, staining stops.

Yes. Flex works well across gentle slopes; the notches in the top allow slight lateral give to follow an incline naturally. However, the edge is no longer perpendicular and a curve is required.
Please reach out for Expert Advice.

For steeper slopes, consider step-ups using taller edging or raised beds.
Zero-Flex needs a smooth base (the base can be inclined, but must be even).

Flex, Rigid & Zero-Flex: a rubber mallet or a hammer, a cordless drill, a spade and a Tek screw bit. That is it.
An angle grinder is only needed if modifying lengths or creating custom corners.

Every set includes pre-attached connector plates and pegs.

Weathering steel garden edging, also known as corten, is built to last for decades in typical UK garden conditions. The patina it forms is a stable, rust-toned layer that protects the steel beneath and slows further corrosion, rather than eating through it like ordinary steel. Lifespan depends on soil, drainage and how close you are to the coast. Our Longevity Guide explains what affects it and how to get the most from your edging.

Both are excellent; it comes down to look and location. Weathering steel (also known as corten) develops a warm, rust-toned patina and suits most inland, well-drained gardens. For gardens within roughly 2km of the coast, weathering steel benefits from extra care, as airborne salt can interfere with patina formation; our Longevity Guide and Product Care Guide cover the steps that make the most difference. For a lower-maintenance option in coastal locations, galvanised steel is a practical alternative with a clean, contemporary grey finish.

Yes. Every profile has a rolled, folded top edge rather than a raw cut edge, so there’s no sharp lip along the top of the edging. It’s a key reason Straightcurve is chosen for family gardens, play areas and lawns where children and pets are about.

Yes. Straightcurve works as a clean lawn edge as well as garden border edging. Set the top edge flush with the turf and you can mow straight over it for a crisp lawn edge, with no strimming along a hard lip. Flex follows curved lawns; Rigid and Zero-Flex keep formal lawns dead straight.
