GRP Pultruded Structural Profiles
Engineered Composites supplies an extensive range of glass fibre reinforced pultruded structural profiles from stock.
The GRP profile sections 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 Engineered Composites 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.
GRP Pultruded Structural Profile Product Range
The following pultruded profiles are carried as stock items in 6m lengths for immediate delivery. The stock lengths can be cut to length if required Other sizes, shapes, lengths, colours and resins can be supplied to order with a typical minimum production order of 300m.
