GRP Channels are suitable for any structural project. Available in various sizes, lengths, colours and resins depending upon the application.
All our fiberglass channels 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. Profiles in other resin systems are available to order. The standard BS EN 13706 Specification for pultruded profiles defines two grades of structural profiles. All Captrad's structural profiles with a wall thickness of over 5mm thick meet the higher performance E23 grade while those at 3-5mm wall meets the E17 grade.
Items in Yellow are standard stock items
The table below shows the minimum properties to comply with the two grades defined in the BS EN 13706.
