GRP Rods and Tubes

Engineered Composites supplies from stock an extensive range of glass fibre reinforced rods and tubes.

Fibreglass GRP Rods

The fibreglass rods are all smooth external finish and with high glass content uni-directional reinforcement. With tensile strength of steel but only a quarter of the weight, tough, flexible, electrically non-conductive fibreglass rods used in all kinds of industrial, agricultural and hobby applications.

The stock lengths can be cut to length if required

Fibreglass GRP Tubes

GRP tubes are stocked in a number of diameters and wall thickness. They are all made by the pultrusion process so have high glass contents and excellent mechanical properties. All of the tubes have a corrosion/weathering barrier built into the surface to give the maximum long-term performance in the most demanding environments.
