Straightcurve is the steel garden edging and raised bed system that turns up on more of The Block 2026 supplier lists than almost any other landscaping brand. It is named on eight of the ten front yard and backyard lists published by Nine, covering four of the five teams.
Straightcurve at a glance
- What it is: modular steel garden edging, raised garden beds and planter boxes, in weathering (corten) steel or galvanised steel.

Seasons seen: The Block 2026.
The Block Head’s take
The Block Head’s take: this is the quiet workhorse of the 2026 yards. It does not get a big on-screen moment, but crisp steel edges around lawns, trees and garden beds are a big part of why the yards look finished on reveal day.

Straightcurve was not named in the episode captions we checked, so these appearances come from Nine’s supplier lists: Rick and Tayla, Sev and Courtney, Chantel and Wyatt and Adam and Jolene.
What it is made of
- Steel: 1.6 mm for edging and 2.0 mm for raised beds and planters, according to a supplier directory listing for the company.
- Finishes: weathering steel gives the rusted look; galvanised steel suits coastal and urban conditions.
- Styles: Flex bends into smooth curves, Rigid suits straight lines or gentle curves, and Zero-Flex is for perfectly straight runs.
- Heights: edging from 75 to 150 mm, raised beds from 240 to 560 mm.
If you are thinking of buying
- Where to buy: Straightcurve says its range is sold through more than 80 independent landscape supply businesses and garden centres in Australia, not through Bunnings.
- Corten staining: weathering steel can leave rust marks on light paving or render nearby. Keep it off pale concrete or seal the surface.
- Plan the shape first: Flex and Rigid are join compatible, so you can mix curves and straight runs in the one garden.
