GRP Composite Cladding

GRP Composite Cladding Panels are manufactured by combining hundreds of thousands of glass strands with pigmented thermoset U.V. resins, to produce an immensely strong and durable panel whilst maintaining an attractive appearance.

Relinea composite cladding can be produced to incorporate several features, including:

  • Any BS or RAL Colour
  • V. Resistant
  • Impact Resistant
  • Any Thickness
  • Graffiti Proof/Resistant
  • High Strength to Weight Ratio

Composite cladding comes with lots of advantages that make our customers prefer it to timber. First, it offers far superior durability in comparison to timber cladding. Our cladding material will last much longer than wood and provide a hardwearing protective barrier. Another benefit of composite cladding is that it is lightweight. This makes it easy to carry and move around when you are installing the boards.

Our industry insight has helped us to develop a low-maintenance, sustainable external cladding, ideal for both new builds and renovations. GRP cladding panels can also be made in a range of perfectly matched finishes to suit your requirements.

Composite Dagger Boards

GRP dagger boards are the ideal replacement for timber dagger boards on railway station canopy fascias. We fabricate the boards to imitate the appearance of traditional wooden valance boards, keeping the dagger boards aesthetically pleasing. Not only are they incredibly easy to install, but our GRP Dagger Boards are also non-conductive and anti-corrosive. Lightweight and durable they make a fantastic alternative to wooden dagger boards.
