Glass Fibre Tubes Cross-Ply
RBJ fibreglass GRP tubes are pultruded with a high volume fraction of fibreglass in a polyester matrix to BS EN 13706 specifications.
We manufacture a wide range of unidirectional GRP tubes from 4mm up to 25mm in diameter. Unidirectional fibreglass tubes have a smooth surface finish and are designed to give ultimate resistance to bending. For GRP tubes 22mm or greater in diameter the fibreglass layup is a combination of multi-layered cross-ply fabrics, giving greater hoop strength that is resistant to bending and torsional forces.
GRP tubes are typically stocked in 5 metre lengths. Unidirectional small GRP tubes are available in white or black. Larger cross-directional GRP tubes are typically grey or white, other colours are available upon request.*
Optional matrices in vinyl ester and acrylic are also available upon request.*
As a UK manufacturer and pultrusion company we are able to tailor production and adapt to individual customer requirements. Please call us to discuss.
