GRP Pultruded Profiles

GRP profiles are light in weight yet high in strength – in fact, as strong as steel but with only one quarter of the density. They are very durable and do not corrode, even in tough environments. Plus, they offer a virtually maintenance-free long service life, making them excellent value for money. 

Suitable for a broad range of applications, pultruded GRP makes an ideal and cost-efficient replacement for traditionally used materials like concrete, steel, aluminium and wood.  A very low electrical conductivity also makes it a great choice for use around electrical installations. 

What is the GRP Pultrusion Process? 

Composite pultrusion is a continuous process used in the production of GRP profiles with constant cross-sections and material properties. Now in use for more than 50 years, the technology ensures a consistent high-quality material with every production run.  

Densely packed continuous fibreglass rovings and matting are pulled by process machinery through a bath of liquid resin. A catalyst is added initiating a polymerisation reaction passing through a high temperature, high-pressure mould. This forms and cures the finished section shape. Finally, the sections are automatically cut to the desired length.   

Stock sections are offered in the most used structural shapes. However, custom made GRP profiles can be requested for bespoke shapes and sizes. Our expert team always welcome enquiries for new moulds and profiles.
