  • Joining 2 lengths together.

  • Using a grinder or power tool saw, remove 50-100mm of the top lip.

  • Slide both pieces together to create a solid joint.

  • Using 50mm washered pins, shot fire through the base into the foundation brickwork, structural steel or concrete.

  • To secure the strap, fix the other end to the top lip of the edge trim

  • Repeat step 3 approximately every 300-400mm for maximum support.

  • Easy to form internal and external corners.

  • Using a grinder or saw, cut out a V shape / Dovetail from the top lip and the base.

  • The section can then easily be bent out for external corners or inward for internal corners.

  • Once the section is cut and bent it can be secured using a power tool.

  • Fix a restraint strap to each side of the bend to increase strength.

  • Repeat step 7 for external corners.

  • Once the system has been fixed in position, spacers can be placed to support the reinforcement.

  • Reinforcement placed on top of the spacers.

  • Concrete should be poured flush to the top edge of the Metal Edge Trim. Ensure that pumped concrete is deposited a minimum of 1.0 metre away from the Metal Edge Trim and is then raked towards the formwork.

  • Finished concrete pour with perfect level.

  • Ready for next phase.

The system is widely used in the residential housing sector with several key housebuilders adopting the process to form floor slabs. The use of Steel Edge Trim can effectively reduce the reliance on highly paid joinery skills and costly shuttering materials. The inherent simplicity and speed of installation compared with traditional construction methods can also help reduce delays on site caused by unfavourable weather


As the system is left permanently in place there are no associated costs of removal and disposal, thus improving efficiencies and minimising waste to landfill
