Conceal Fixing vs Standard Corten Edging: Which Should You Choose?
Conceal Fixing vs Standard Corten Edging: Which Should You Choose?
You've decided on corten steel edging—the warm, durable, modern look is exactly what your garden needs. But now you're facing a choice: conceal fixing or standard edging? What's the difference, and does it really matter?
It does. Each approach has distinct advantages, costs, and aesthetic implications. Let's break down both options so you can choose confidently.
The Basics: What's the Difference?
Both achieve the same goal—creating a durable corten border for garden beds, pathways, or landscaping—but the fixing method (how the steel is secured to the ground) differs fundamentally.
Standard Edging
Standard corten edging is installed with visible fixings: bolts, screws, or brackets that attach the steel edge to a timber or concrete base. The fixings are on the surface, often on the outer face or top edge of the steel, where you can see them.
Conceal Fixing Edging
Conceal fixing uses a specialised bracket system that's buried or hidden beneath the soil line or within the edging profile itself. The fixings are invisible once installation is complete, creating a seamless, minimalist appearance.
Standard Edging: The Straightforward Choice
How It's Installed
Standard edging attaches to a timber or concrete base with visible bolts or brackets, typically spaced 300–400mm apart. The fixing points are exposed—you see them on the steel's face or top edge. Installation is straightforward and relatively forgiving; minor misalignments are easy to correct.
Visual Appearance
This is the tradeoff. You get visible bolts or brackets, usually stainless steel or corten to match the edging. For many projects, this is fine—the hardware becomes part of the aesthetic. For others, it's a visual compromise.
Cost
Standard edging is typically the most economical option. Fixings and brackets are simpler, installation labour is lower, and there's less waste. You're looking at a baseline cost point.
Installation Complexity
Low to moderate. You need a level base, accurate spacing of fixings, and basic tools (wrench, level). It's a job most skilled installers can execute quickly. If you're doing it yourself, standard edging is the most DIY-friendly option.
Where Standard Edging Shines
- Budget-conscious projects: Cost savings add up across long runs of edging.
- High-traffic or heavily-maintained gardens: Easy access to fixings makes adjustments and repairs simple.
- Where industrial-style aesthetics work: Gardens embracing raw, architectural materials; visible hardware reads as intentional.
- Temporary or modular installations: If the edging might need to be relocated, standard fixings allow easier removal.
- Sloped or uneven ground: Standard fixings are more forgiving of minor height variations.
Conceal Fixing Edging: The Refined Approach
How It's Installed
Conceal fixing uses a special bracket system (usually L-shaped or specialised channel) that's secured to a buried concrete base or timber runner. The bracket sits below the soil line or within a recess in the edging profile, completely hidden from view. The steel edge appears to float, unsupported, with no visible hardware.
Visual Appearance
Seamless and minimalist. Without visible bolts or brackets, the corten edge creates a clean, uninterrupted line. This is hugely appealing in contemporary garden design and when you want the material itself to be the star, not the fixings.
Cost
Conceal fixing is 15–40% more expensive than standard edging, depending on complexity. Custom brackets, additional base preparation, and more precise installation labour all contribute to higher cost. For large projects, the cumulative difference is significant.
Installation Complexity
Moderate to high. The base must be perfectly level and precisely positioned. Brackets must be accurately spaced and secured before the steel is installed. Adjustments mid-installation are trickier. It requires skilled installers who understand the system, and mistakes are harder to hide (or correct) than with standard edging.
Maintenance Considerations
Once installed, conceal fixing is equally low-maintenance as standard edging. The hidden brackets don't require ongoing attention. However, if the edging needs repositioning or removal in future, accessing and modifying hidden brackets is more complicated.
Where Conceal Fixing Shines
- Contemporary or minimalist gardens: The clean, hardware-free aesthetic is essential to the design vision.
- High-end residential or boutique landscapes: When visual refinement and premium aesthetics justify the extra cost.
- Long, continuous runs of edging: Cumulative visual impact of hidden hardware is worth the investment.
- Garden bed edges in prominent locations: Focal beds, frontage, or areas you photograph frequently benefit from seamless appearance.
- Pools, water features, or entertaining spaces: Where the edging is closely viewed and needs to be visually pristine.
- Projects prioritising design over budget: When aesthetic purity is the brief.
Head-to-Head Comparison Table
| Aspect | Standard Edging | Conceal Fixing |
|---|---|---|
| Visible Fixings | Yes, bolts/brackets visible | No, completely hidden |
| Visual Appeal | Industrial, honest | Refined, minimal |
| Installation Cost | Lower (baseline) | 15–40% higher |
| Installation Complexity | Low to moderate | Moderate to high |
| Time Required | Faster | Slower (more precision needed) |
| Base Requirements | Level, basic | Perfectly level, precisely positioned |
| DIY-Friendly | Yes | Not recommended |
| Future Adjustments | Easy | More complicated |
| Ongoing Maintenance | Minimal (same as conceal) | Minimal (same as standard) |
Cost Breakdown: What You're Actually Paying For
If standard edging costs $100 per linear metre, conceal fixing might cost $120–$140 for the same run. The difference covers:
- Custom bracket engineering and fabrication
- More precise site preparation and base work
- Skilled labour (installers must be experienced with conceal systems)
- Potential site-specific adjustments
On a 50-metre project, that's $1,000–$2,000 extra. On a 5-metre feature bed, it's $100–$200 more. Consider scale when evaluating ROI.
The Hybrid Approach: Smart Combining
You don't have to commit to one system across your entire project. Consider a hybrid approach:
- Use conceal fixing on visible focal areas—pool surrounds, garden bed edges you see daily, entrance borders.
- Use standard fixings on utilitarian sections—back-garden boundaries, utility area edging, less-viewed perimeter runs.
This balances visual refinement where it matters with cost efficiency where it doesn't. You get the best aesthetic impact without the full premium price tag.
Choosing Your System: A Decision Framework
Ask yourself these questions:
- How prominent is this edging in your garden? Visible daily → consider conceal fixing. Out of sight → standard is fine.
- What's your aesthetic priority? Refined minimalism → conceal fixing. Honest, industrial look → standard works.
- What's your budget flexibility? Extra cost justified → conceal fixing. Budget-tight → standard is the smart choice.
- How long is the run? Lengthy borders → conceal fixing's cost-per-metre adds up, but visual impact justifies it. Short feature sections → standard often makes sense.
- Will you adjust or relocate this edging in future? Yes → standard is easier. Probably not → either system is fine.
Quality and Durability: Both Are Built to Last
Both standard and conceal fixing deliver the same long-term durability. The corten steel itself weathers beautifully regardless of how it's fixed. Fixings on both systems are stainless steel or corten, designed to outlast the edging itself. The choice is aesthetic and budgetary, not about longevity.
