January 2020 Question


Service risers or shaft risers are mainly found within a construction, demolition or refurbishment site to help provide a safe working environment. These service risers cover potential fall hazards and falling debris through open shafts and uncovered voids. This is a core concern when it comes to health and safety and it is usually dealt with straight away. Other systems can be installed to solve this; steel grating, scaffolding or temporary plywood covers which can fail or are easily breached.


Anti Slip GRP Grating


Grating is usually applied over these potential hazards but if the building being fitted is a high-rise, steel grating can be expensive. GRP grating is a much cheaper and more reliable alternative to heavy, flawed steel grating. GRP grating weighs about 25% of standard steel grating and can be fitted without any equipment other than hand tools.





Here at Fibregrid we offer the perfect solution to these risks in the form of our Anti Slip GRP grating which can be made bespoke to your requirements.

The key features of our GRP grating include:


Slip Resistance

Our Anti Slip GRP Grating comes with a slip resistant top surface as standard and easily exceeds the minimum requirements of the ‘extremely low’ potential for slip rating demanded by the UK Slip Resistant Group Guide of 2002.


Impact Resistance

GRP grating has high energy absorption and can be repeatedly knocked without causing permanent damage making it perfect for withstanding dropped tools or construction materials.



At only 12.3kg per square metre (25mm high) and 19.5kgs per square metre (38mm high) you don’t need any heavy lifting gear or specialist equipment. A two-person team can easily complete the job which minimises the difficulty in installing on higher floors.


Fire Retardancy

Our GRP grating has been tested in accordance with BS 476: Part 7 and also meets the requirements of Class 2 (certificates available on request). If you need a higher resistance and low smoke generation, then a phenolic resin is available. Unlike steel, there is no danger of sparking if metal objects are dropped on the grating and within the close proximity of potential gas lines; this is a crucial factor in deciding between steel grating and GRP grating.
