This project demanded prompt supply on a grand scale.
Approximately 625 meters of custom designed and manufactured Fibrelite FRP trench covers and frames were specified for this project at one of the UK’s largest power stations. Customization, manual handling and longevity were the key requirements, including nonstandard frame sections consisting of laser fusion welded and hot dip galvanized steel.

Key Requirements
- This project demanded prompt supply on a grand scale: approximately 625 meters of trench covers (with frame sections to suit).
- D400 load rated FRP composite trench covers which met the BS EN 124 testing standards while remaining light enough for safe manual removal and replacement.
- Covers fitted with a secure bolt down system prior to despatch.
- ‘Shaped’ covers to accommodate trench directional changes.
- To ensure extended service life, nonstandard frame sections consisting of laser fusion welded, hot dip galvanized steel were requested.
