Transportation & Infrastructure
Why Transportation & Infrastructure Needs FRP
Infrastructure assets must last decades with minimal maintenance. FRP grating — lightweight, corrosion-proof and non-conductive — serves bridge walkways, rail platforms and roadside maintenance decks where steel and timber fail.- Bridge deck corrosion and de-icing salt attack
- Weight limits on existing structures
- Traffic vibration loosening conventional fixings
- Electrical safety near rail infrastructure

Technical Specifications & Compliance
Application-specific engineering reference for Transportation & Infrastructure — corrosion rating, load criteria, governing codes and the recommended ZeAllgrate configuration. Use this as the specification starting point; final design must be verified against certified load/span charts and the project's governing codes.
| Parameter | Specification for Transportation & Infrastructure |
|---|---|
| Corrosion Level | Medium De-icing salts, road runoff and atmospheric pollution; plus weight limits on aging structures. |
| Typical Load Requirements | Bridge inspection walkways 50 psf (2.4 kN/m²) pedestrian; maintenance-vehicle decks 250 psf (12 kN/m²) or AASHTO lane loads; transit platform edge loads per AREMA. |
| Applicable Standards & Regulations | AASHTO LRFD (bridge design), AREMA (commuter/rail), OSHA 1910.28/1910.29, NFPA 130 (fixed guideway transit/tunnel fire), ISO 14122, local DOT specifications. |
| Recommended Resin System | ZeAll ISO for general bridge & road service; ZeAll FR fire-retardant grade mandatory in tunnels and transit subways; UV-stabilized for exposed structures. |
| Recommended Grating Type | Pultruded I6015/T5020 for under-deck bridge inspection walkways (weight-critical); ZeAll FR pultruded for tunnel service; Molded 38.1 mm for station-platform edge covers. |
Resin systems: ZeAll VE (vinyl ester — severe corrosion), ZeAll ISO (isophthalic polyester — general service), ZeAll FDA (food/potable grade), ZeAll FR (extra flame-retardant), Phenolic (fire/smoke-critical). Grating types: Molded (bi-directional), Pultruded (long-span), Mini-Mesh (fine openings), HLC (high-load capacity).
Transportation Service Requirements
| Requirement | ZeAllgrate Response |
|---|---|
| Heavy / concentrated loads | Pultruded and high-load molded sections |
| Fire performance | E84 class per code for stations and tunnels |
| Wet slip risk | Grit-top on exposed decks and stairs |
| Long-life assets | Decades of service with no paint programme |
Specification Guidance
Transportation infrastructure specifies for load, fire and durability: bridge inspection walkways and station platforms are designed to the deflection-limited load table with the concentrated case checked, the E84 class is confirmed for rated areas, and grit-top handles the wet exposed surfaces. Lightweight panels install over live rail and road corridors with minimal disruption — no hot work, no heavy crane lifts. The case library documents bridge and station walkway installations.
