Every contractor knows that riser voids – the aperture left to accommodate M&E services on multiple floors of a building – are a major health and safety issue on any construction site.

To influence the way the construction industry approaches the design, build and use of risers, our company has designed Risegrate.

Easy installation of Risergrate

Installation Options

  • 1 Void perimeter supports utilising GRP angle
  • 2 Void cross members utilising GRP I beam
  • 3 Easily cast into concrete slab

Why GRP riser grating is the right choice for you

The product is described as Glass reinforced plastic, a 100% protective product that does away with previous systems, such as steel grating, scaffolding or temporary plywood covers, which can be breached, or fail.

When M&E services are ready to be installed, the grating is easily cut using a jig saw to form the holes required for the riser services.

The use of Fibreglass Grating eliminates maintenance costs, since painting is not required. GRP Grating materials weigh about one quarter of steel grating, and two men can easily handle and fit the panels without the need for any equipment other than hand tools.

The proven gritted anti-slip surface of our moulded grating has one of the highest degrees of slip resistance ever measured for a walking surface, especially in wet, oily or frosty work areas. The integral gritted anti-slip top surface provides long-lasting slip resistant qualities. The material has excellent corrosion resistance, a factor which makes it a logical and cost-effective alternative to conventional steel materials.
