Why Steel Kerbing Has The Edge On Concrete

Concrete pin kerbing is the traditional product for creating stable, well-defined borders between hard and soft landscape surfaces or between different types of hard landscape surfaces such as block paving and asphalt. But what if you could use another product that offers better quality at a similar – or even lower – price?


If you were to define quality in kerbing products, you would probably look for some or all of the following:
  • durability
  • stability
  • precise fit
  • good looks
  • professional finish
  • ease of use

Bison steel kerbing from landscape edging specialists ExcelEdge offers all this, and more.


Developed at their East Sussex innovation centre and made solely in the UK, Bison is manufactured from high-grade 2mm galvanised steel, folded to create a 7mm-wide edging suitable for footpaths and driveways.


Unlike concrete pin kerbing, Bison steel kerbing won’t split, shrink or crumble when exposed to the elements and its galvanised finish ensures it will outlast concrete.

While its flexibility allows landscapers to incorporate elegant curves into their designs, the interlocking ends and integral feet on both sides of Bison kerbing ensure precise and stable installation.


The folded top edge of Bison steel kerbing creates a smooth, visually appealing finish with no sharp corners, but at only seven millimetres wide it provides support without detracting from the beauty of landscape products.


High UK manufacturing standards guarantee every length of Bison kerbing is a work of precise, civils-quality engineering. So how can it compete with concrete pin kerbing on cost?

How better quality kerbing comes at a lower cost

In terms of cost per linear metre, Bison steel kerbing is more expensive than concrete, but when you factor in all the costs of delivery and installation, Bison has the edge. 


As it is 66% lighter than concrete (per linear metre) and held down with fixings rather than concrete haunching:
  • transport costs to site are lower, as smaller quantities can be easily carried in vans or small trucks
  • fewer drops are needed for larger quantities
  • installation can be carried out faster and by fewer workers
  • surfaces can be laid immediately after installation, avoiding costly delays


Add to this the cost of replacing pin kerbs damaged on site, and concrete is no longer the cheaper option.
