GRP Stairs

Relinea offers customers extensive knowledge and experience in the design, manufacture, and installation of Internal and external staircases. Whether it’s for general access, fire escape stairs, one or two steps to a doorway or platform, or a multi-story staircase, we have a solution for you.

GRP stairs are perfect for replacing slippery steel or rotten wooden steps. Manufactured using Relinea Re-Grid GRP Open Mesh Grating, the anti-slip grit does not chip or peel away from the grating and does not compromise the slip resistance. This embedded grit finish provides a steadier grip underfoot in wet, icy, or greasy conditions.

The GRP grating, handrailing, and structural profiles we use to build our stairs are non-corrosive and weather resistant. GRP is warm to the touch, this is an important factor to consider for staircases and handrails that are being used in outdoor contexts. As they are not subject to cold, or extreme heat, they are much safer to climb.

GRP Staircases outperform their conventional steel, aluminium and wooden counterparts across all key criteria:

  • High strength to weight ratio
  • Anti-slip
  • Low maintenance costs
  • Low installation costs
  • Long lasting and durable
  • Corrosion resistance
  • Non-conductive

Staircase components are produced in lightweight fibreglass sections that are easy to transport and handle. Our stairs can be prefabricated at our manufacturing facility and delivered to site for a simple and easy installation using standard hand tools, saving you time and money.
