Why Steel Kerbing Is More Cost-Effective Than Concrete

Steel edging might appear more expensive than traditional concrete pin kerbing, but a price list comparison doesn’t tell the whole story. Let’s look at the whole picture, from purchase to installation and beyond.

Yes, steel edging is on the face of it a more expensive product. That’s because you’re getting a far superior product that will outlast concrete and keep looking good for longer. You might say that like for like, you get what you pay for.

But when we factor in all associated costs, we start to get a different picture.

Steel edging is cheaper than concrete to store and transport

If you’re a wholesaler or a large user, you probably need to keep stocks of edging and pin kerbing for call-off. 
  • Concrete pin kerbing is bulkier, so needs more storage space
  • Concrete is heavier, so isn’t suitable for high bay racking – not only does racking have loading limits, but storing heavy concrete castings above head height is a potential safety hazard
  • Concrete also tends to chip, crumble and shed dust – regular sweeping to maintain a tidy, safe warehouse is another hidden cost to consider

Bulk and weight also increase transportation costs from the manufacturer to the reseller or direct to site.
  • Vehicle weight and volume restrictions limit the amount of concrete kerbing that can be delivered per load, resulting in multiple deliveries for the same linear meterage of edging
  • Craning-off weight capacity also means that concrete kerbing needs more lifts than steel edging to unload the same linear meterage

Steel edging is cheaper than concrete to install

Time is money. Where are you spending the most time when you lay edging materials?

  • On-site movement – often by hand – of edging material will take more time with heavier concrete than with steel. 
  • With less physical fatigue and fewer workers needed to carry and lay the edging, more steel can be laid in a day or per man-hour than concrete.
  • Steel edging is more easily and rapidly bolted into position and requires no concrete haunching, so surfaces can be laid on the same day.
  • Concrete is more prone to damage while being carried and laid, or when hard surfaces are being laid and rolled, so the additional costs of removing and replacing the kerbing, plus the cost of the replacement material, need to be factored in.

Even after installation is complete, concrete pin kerbing is more prone to damage and deterioration than steel edging, so the ongoing costs of maintaining safe, attractive edging will be higher.
