Choosing the right garden edging comes down to one simple question: what shape is your garden? From there, the right Straightcurve product becomes obvious. This guide walks you through each option — what it does, when to use it, and which finish suits your project.
Steel Garden Edging
Steel edging creates a clean, permanent boundary between lawn, garden beds, and pathways. It holds its shape over time, doesn't rot or warp, and looks sharp whether it's freshly installed or years old. Straightcurve offers three profiles depending on how much flexibility your design needs.
Flexline — for curves and flowing shapes
If your garden has curves — or you want it to — Flexline is the one to reach for. The profile is designed to bend smoothly by hand without kinking, so you can create gentle sweeps or tight curves with consistent results. It's the most versatile edging in the range and suits most residential garden projects.
Available in 75mm, 100mm, and 150mm heights.
Rigid — for straight lines and formal layouts
When your design calls for clean, straight runs, Rigid edging holds its form without bowing or shifting. It's ideal for structured, formal gardens and high-pressure applications like driveway borders where the edging needs to stay put under load.
Available in 100mm and 150mm heights.
Zero-Flex — for maximum rigidity under pressure
Zero-Flex is the most rigid profile in the range. Where standard Rigid edging handles most straight-line applications, Zero-Flex is built for situations where ground movement, heavy loads, or long-term permanence demand something that simply won't budge. Think commercial projects, retaining-style borders, or areas with significant soil pressure.
Available in 100mm and 150mm heights.
Which Finish Should You Choose?
All Straightcurve steel edging is available in two finishes. The right choice depends on the look you're after and how much long-term maintenance you want to do.
Weathering Steel — the natural, low-maintenance choice
Weathering steel is designed to rust on the surface. That might sound counterintuitive, but the rust forms a stable, protective patina that actually seals the steel underneath and prevents deeper corrosion. Over time it develops a rich, warm, earthy tone that blends beautifully into garden settings. Once the patina forms, it's essentially self-maintaining — no painting, no sealing, no upkeep. It's the most popular choice for residential gardens where a natural, premium look is the goal.
Galvanised Steel — the most weather-resistant option
Galvanised steel is hot-dip galvanised for maximum corrosion resistance, making it the toughest finish in the range. It has a clean, bright silver appearance straight out of the box and can be powder coated in any colour if you want to match a specific palette or fence colour. It's the right choice for coastal environments, high-moisture areas, or anywhere you want the option to customise the colour down the track.
Raised Garden Beds
Raised beds improve drainage, make planting and weeding easier, and give your garden a structured, intentional look. Straightcurve raised garden beds use the same quality steel as their edging range and come in two profiles.
Flex Raised Garden Beds — curved or straight, your choice
Flex raised garden beds can be shaped into curves, circles, or straight-sided rectangles — whatever suits your space. They're a great option if you want flexibility in the design without committing to a fixed shape. Available in 240mm, 400mm, and 560mm heights.
Rigid Raised Garden Beds — clean, straight-sided permanence
Rigid raised garden beds are built for straight-sided, permanent installations. They hold their shape under soil pressure and look sharp in formal or structured garden designs. Available in 240mm, 400mm, and 560mm heights.
Pre-Curved Rings
When you need a perfect circle, Pre-Curved Rings take the guesswork out of it. They arrive already formed into a precise ring — no bending, no measuring, no fussing with stakes to hold a curve in place. Just position, secure, and you're done.
Pre-Curved Rings — perfect circles, zero effort
Pre-Curved Rings are the fastest way to create a professional-looking circular garden feature. Because they're pre-formed at the factory, every ring is a consistent, true circle — something that's genuinely difficult to achieve by hand with standard edging. They're particularly popular for tree surrounds and feature planting areas where the circle becomes a design element in its own right.
Available in weathering steel and galvanised steel finishes.
Custom Planter Boxes
Straightcurve Zero Flex Planter Panels let you build a fully custom planter box in any shape or size — from a compact courtyard herb garden to a large-scale landscape feature. Precision-engineered from the same quality steel as the edging range, they're designed for patios, courtyards, balconies, and entertaining areas where you want a clean, modern look without digging into the ground. Mix and match panel lengths and join them with matching accessories to create exactly the layout you need.
Custom Planter Boxes — build any shape, any size
Panels are available in six lengths (400mm, 600mm, 800mm, 1000mm, 1200mm, and 2000mm) and two heights — 400mm for low-profile beds and shallow planters, or 560mm for deeper root crops, vegetables, and feature trees. Choose from Weathering Steel for a warm Corten patina that develops naturally over time, or Galvanised Steel for maximum corrosion resistance in coastal or high-moisture environments.
Panels join together with straight joins, closed corners, and reverse corners, and are braced to keep the structure rigid and square. All fixings are available to add to your order at checkout.
Not Sure Which Product Is Right for You?
A simple way to decide: if your garden has curves, start with Flexline. If it's all straight lines, go Rigid or Zero-Flex. If you need a perfect circle, Pre-Curved Rings are the answer. If you want a natural look that blends into the garden, choose Weathering Steel. If you're near the coast, want to paint it, or need maximum durability, go Galvanised.
