GRP Pultruded Grating

GRP Pultruded Grating is widely used as a surface for industrial flooring – including walkways, platforms, flooring, trench covers, ramps and cable trough covers. Where traditional materials like metal and wood are subject to corrosion and chemical attack, fiberglass grating offers a safe, long-lasting, and economical way to protect your walkways and platforms.

Relinea Re-Grate GRP Pultruded Grating is made up of a 70% glass to 30% resin ratio. It encompasses twice the stiffness of Re-Grid Moulded Grating, allowing it to span greater distances. The uni-directional strength of our Re-Grid GRP Pultruded Grating also allows it to withstand a high load capacity. Due to its outstanding rigidity, it can be used with certainty where wide support spans are needed.

Relinea’s range of Structural Grating Products possesses many benefits over traditional materials. Depending on the specification, we offer a wide choice of resin types that enable the product to withstand the harshest of industrial & commercial environments.

The relatively light weight of the grating means that fabrication can be carried out on-site without affecting the corrosive resistance properties of our pultruded grating. The grating can be manually handled into position and can be easily cut using standard hand power tools. However, if cutting into Re-Grate is required for pipework, it would be more beneficial to use Re-Grid Moulded Grating, as its bi-directional strength will be able to withstand this extraction.

Anti-slip GRP Open Mesh, Fibreglass Solid Top Grating, and GRP Pultruded Grating Systems meet all Health & Safety requirements whilst being lightweight and maintenance-free. GRP Grating can be easily fabricated on-site meaning lower installation costs and fewer man-hours.

  • Re-Grid: GRP Open Mesh Grating – A high strength square mesh structure with bi-directional strength.
  • Re-Deck: GRP Solid Top Grating – A square mesh structure with 3mm thick integrally bonded plate cover
  • Re-Grate: GRP Pultruded Grating – A uni-directional high strength structure. Incorporates twice the stiffness of open mesh grating as it can span greater distances.

Relinea’s GRP Fibreglass Grating products are available in a range of resins, (including phenolic resin with extreme fire resistance) to meet specific environmental demands, including hazardous chemical applications. In addition, there is a range of surface finishes including meniscus, grit and smooth to meet even the most stringent requirements in terms of slip resistance and ease of cleaning.
