  • Can be cut at any point without compromising strength.
  • Supplied in durable galvanised steel for weather resistance.
  • Radiused edges on the top inside corners help reduce damage to forklift wheels.
  • The sharp edge on the inside top face of each hole helps ensure a neat finish when trowelling-in.
  • Compatible with a choice of TD plate dowels.
  • A choice of straightforward installation methods.
  • Can be tailored to specific project requirements – contact our technical engineers to discuss.



  • Ideal for external applications, such as yards, hardstandings and roadways.
