GRP Pultrusions
GRP Pultrusions - GRP Profiles
GRP Pultrusion and GRP Profiles are composite structures that are used in a wide range of applications, offering excellent chemical resistance, high strength and thermal values. Captrad composite structures include GRP Angle, GRP Box Section, GRP channel, I-Beam, Wide flange beam, GRP Tube, GRP Rods, Flat Bars and others etc. These pultruded GRP Profiles are used in a wide range of applications, offering a unique combination of chemical resistance, size stability, high strength, and thermal, electric non-conductivity. Each composite structure shape is available in a number of dimensions to suit a variety of design and application requirements. For special uses, custom shapes are also available.
Captrad Ltd also has a full range of GRP Cable Trays and GRP Cable Ladders that can be used in a variety of environments from the rail, offshore to industrial. All our products are produced under ISO 9000 registered quality assurance systems and are all fully compliant with BS EN13706- Specifications for Pultruded Profiles.
GRP pultruded profiles are supplied from stock and we have an extensive range of glass fibre reinforced structural profiles all extruded profiles are manufactured to the same high quality.
Captrads composite structures are made from glass reinforced isophthalic polyester resin with a polyester surface veil. This combination gives excellent corrosion resistance and weather ability at an economic cost.
Composite structures made from these profiles are substantially lower in cost than stainless steel and cost-competitive with hot-dipped galvanised mild steel.
Pultruded GRP is also available in other resin systems upon order.
The standard BS EN 13706 - Specification for GRP Pultruded Profiles, defines two performance grades. Our structural profiles (t > 5mm) can meet the higher performance E23 grade.
Our GRP extruded profiles meet the requirement of the Drinking Water Inspectorate for use in potable water. All of the GRP Pultrusion is available in a variety of resins depending upon the application:
- Polyester is suitable for most industrial applications.
- Vinylester affords improved corrosion resistance and physical properties.
- Epoxy offers superior thermal stability and corrosion resistance.
- Modar improves fire performance and smoke emissions.
- Phenolic maximises fire performance and is offered as an alternative to Modar.
