FRP Grating for Bridges, Rail & Infrastructure
Infrastructure owners are the single largest adopters of FRP walkway systems — not for corrosion alone, but for weight. A steel walkway adds tonnes of dead load to an aging bridge; the same walkway in FRP adds roughly forty percent less, often removing the need for a structural assessment altogether.
Where it goes
- Bridge maintenance walkways and inspection access
- Rail station platform-end walkways and cable duct covers
- Tram and light-rail trench covers along platforms
- Airport service road drainage decking
- Tunnel emergency walkways and niche access
- Pump station and drainage gallery decking
Why infrastructure engineers specify it
| Driver | Effect | Typical spec |
|---|---|---|
| Dead load limits | ~19 kg/m² vs 30–35 kg/m² steel | 38 mm molded |
| Chloride exposure (de-icing salt) | No coating to fail, no rust bleeding onto concrete | ISO polyester or vinyl ester |
| Anti-slip in all weather | Integral grit surface, stays put at -20 °C | Gritted, high-vis nosings |
| Cable and duct covers | Two-person lift, no bonding required | Sealed-edge panels with lift eyes |
The rail trench pattern
Station trench covers take luggage wheels, cleaning machines and the public. Covers in mini-mesh grating with sealed edges stop coins, keys and heels; panels span the full trench width so nothing rocks underfoot; and because FRP is non-conductive, stray-current corrosion and bonding questions disappear from the maintenance manual.
