FRP Grating for Power Generation & Substations
Around live equipment, the deck itself is an electrical hazard. Steel grating and trench covers inside a substation or switchyard must be bonded, earthed and periodically tested — or excluded. FRP grating is electrically non-conductive and non-magnetic by nature, which is why transmission operators specify it for switchgear platforms, cable trenches and transformer access.
Where it goes
- Substation switchgear operating platforms and walkways
- Cable trench covers across switchyards and plant roads
- Step-up transformer plinths and inspection decks
- Cooling tower fan decks, fill access and stair towers
- FGD (flue gas desulfurization) scrubber platforms — acidic service
- Battery room and electrolysis area flooring
Selection by zone
| Zone | Panel | Why |
|---|---|---|
| Switchgear walkways | 38 mm molded, mini mesh where tools are carried | Non-conductive; heel-safe openings |
| Cable trench covers | 30–38 mm molded, sealed edge option | Removable, no earthing bonds needed |
| Cooling tower areas | 38–50 mm molded, ISO polyester | Warm humid chloride-laden air |
| FGD scrubber platforms | 50 mm molded or pultruded, vinyl ester | Slurry splash and acid duty |
Trench covers: the quiet win
A switchyard can hold hundreds of metres of cable trench. Steel covers rust, warp, need earthing checks and end up too heavy to lift safely. Molded FRP covers weigh roughly a third as much, never corrode, and a two-person crew lifts them without a permit-to-work conversation about electrical bonding.
