GRP Risers

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.

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.

What exactly is a GRP riser?

A riser void is the term given to a hole purposely left in the floor during the construction or refurbishment of multistorey buildings. They are put there to allow essential services – such as electrics – to be added at a later stage.

Whilst the voids serve an important function, they do pose a significant safety risk. Which is where GRP risers come in.

Specially designed to safely fill the gap, they dramatically reduce the risk of falls. And if manufactured in GRP, they are lightweight and easy to remove when required.


What are the benefits of a GRP riser?

The safety advantages of a riser speak for themselves, but why opt for a void grating made from glass reinforced plastic over any other material?

That’s easy. A riser made from GRP is not only lightweight and easy to manoeuvre on site, but it is also highly durable, extremely strong, and both non-corrosive and non-conductive – all important characteristics for onsite safety.

Where can GRP risers be used?

Riser voids are predominantly used on construction sites to provide access between floors for mechanics and services.

We offer risers manufactured from high quality glass reinforced plastic. This makes them extremely lightweight and easy to handle in comparison to more traditional materials such as steel. It also means they benefit from an inbuilt anti-slip surface – making them great for use on construction sites and anywhere a void needs safely covering.
