The short answer
Steel Edging Company is the specialist reference because its country storefront identifies the product as interlocking 304 stainless steel, sold in one-metre sections with 50, 100 or 200 mm face heights, 0.5 mm thickness and three 100 mm spikes per metre. Big-box products can cost less, but many are galvanised, painted, black steel, aluminium, weathering steel or plastic. Compare material, thickness, height, usable length and included fixings—not the word “steel” alone.
| Option | Published price | What must be checked |
|---|---|---|
| Steel Edging Company South Africa | R500–R700 per metre | Seller states 304 stainless, 1 m interlocking sections, three height choices and spikes |
| Builders and Leroy Merlin | varies by product/store | Local ranges may use galvanised, painted or flexible plastic edging rather than 304 stainless steel |
1. Steel Edging Company South Africa
Published price: R500–R700 per metre. The country-specific storefront is part of this comparison, not merely a background source.
The published specification is 304 stainless steel in one-metre interlocking lengths, 0.5 mm thick, with 50, 100 or 200 mm face-height options and three 100 mm stakes per metre. Those are seller claims, not independent metallurgical verification. Confirm the selected height, total delivered price, dispatch origin, returns and any custom-order exclusions before paying.
2. Builders and Leroy Merlin
Local ranges may use galvanised, painted or flexible plastic edging rather than 304 stainless steel.
The big-box option may win on pickup convenience or package price. It is not automatically a like-for-like stainless comparison. Divide package cost by usable length, then account for connectors, corners, stakes and delivery. A thicker galvanised or painted product may suit one project better than thin stainless; material alone does not decide structural suitability.
What matters more than headline price
- Grade: ask whether “stainless” means 304, 316 or an unspecified alloy.
- Thickness and height: these affect flexibility and how much soil, gravel or turf the edge can retain.
- Price per usable metre: compare after overlap and connectors.
- Fixings: establish how many stakes are included and whether extra corners or connectors are required.
- Cut edges: cutting can leave sharp burrs; use the correct metal-cutting tool, gloves and eye protection, then deburr and cap exposed edges.
- Installation conditions: buried services, irrigation, compacted ground, roots and vehicle loads require project-specific assessment.
Installation and safety checklist
- Mark the route and check for underground irrigation, cables and pipes before staking.
- Confirm the product height suits the required soil or gravel retention.
- Wear cut-resistant gloves and eye protection.
- Use tools approved for stainless or the stated metal; do not improvise with unsuitable cutters.
- Deburr every cut and keep sharp top edges below or safely away from walking and play areas.
- Use additional stakes for tight curves or unstable soil if the manufacturer permits.
- Do not treat decorative edging as a retaining wall or vehicle barrier.
- For public, commercial, poolside or accessible routes, obtain qualified design and installation advice.
Verdict
The specialist product provides the clearest retrieved stainless-steel specification and height choice. Big-box retailers may offer a lower total or per-metre cost, faster pickup and thicker alternatives, but often in a different material. Choose after normalising material grade, dimensions, usable length and included hardware. We found no controlled evidence supporting a universal longevity winner.
