Captrad composite structures include Angle, Box Section, Channel,
I-Beam, Wide flange beam, Round Tube, Rods, Flat Bars and others etc. These pultrusions are used in a wide range of applications, offering a unique combination of chemical resistance, size stability, high strength, and thermal, electric nonconductivity. Each composite structure shape is available in a number of dimensions to suit for 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 rail, offshore to industrial.

Captrad Ltd supplies from stock an extensive range of glass fibre reinforced structural profiles.

Captrads composite structures are made from glass reinforced isophthalic polyester resin with a polyester surface veil. This combination gives excellent corrosion resistance and weatherability at an economic cost.

Structures made from these profiles are substantially lower in cost than stainless steel and cost competitive with hot dipped galvanised mild steel.

Profiles in other resin systems are available to order.

The standard BS EN 13706 - Specification for pultruded profiles, defines two performance grades. Our structural profiles (t > 5mm) can meet the higher performance E23 grade.

The profiles meet the requirement of the Drinking Water Inspectorate for use in potable water.

All of the pultrusions are available in 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
