GRP grating clips are engineered fastening systems designed to securely fix Glass-Reinforced Polymer (GRP) grating panels to steel or GRP support structures. They ensure accurate alignment, safe load transfer, and long-term stability in industrial installations. IMS supplies a comprehensive range of clip types manufactured from high-grade stainless steel, providing superior corrosion resistance and mechanical strength in demanding environments.

Technical Overview
GRP clips are an essential part of any GRP flooring or platform system. They prevent panel movement under load, reduce flexing, and maintain the correct spacing between grating sections. Each clip design is optimised for specific grating profiles — whether moulded, pultruded, or solid top — ensuring consistent contact and secure retention.

At IMS, all GRP grating clips are precision-manufactured and tested to ensure durability, ease of installation, and compatibility with standard UK and European grating systems.

Material and Construction

  • Material: 316-grade stainless steel for maximum corrosion resistance.
  • Clip types: M-Clips, C-Clips, L-Clips, G-Clips, and bespoke fixings available.
  • Fasteners: Supplied with stainless steel bolts, washers, and nuts for complete assemblies.
  • Compatibility: Suitable for 25mm, 38mm, 50mm, and 55mm GRP grating thicknesses.
  • Finish: Polished or passivated stainless steel to resist oxidation in outdoor or chemical environments.

Performance Features

  • High mechanical strength and vibration resistance.
  • Excellent corrosion resistance in marine, chemical, and outdoor settings.
  • Quick and secure installation using standard hand tools.
  • Maintains grating position without distorting or damaging panel bars.
  • Reusable during maintenance or periodic inspections.
  • Available in full trade quantities or custom fixing sets for large installations.

Applications
