What do our clients think about us?

  • GRP Support System and Flooring

    Relinea worked with the M&E company to provide a GRP support system and flooring to suit the riser layout. The provision of drawings and this coordination with the M&E drawings to suit each individual riser was extremely helpful. Relinea’s system was installed quickly and safely. I would happily recommend Relinea and their GRP system which is ideal for riser applications.
