Phenolic pultruded grating is made of phenolic resin and reinforced fibers via pultrusion process. It features Class A non-combustibility, temperature resistance from -196℃ to 200℃, and corrosion resistance to acids, alkalis and salts. Moreover, it has passed ASTM F3059 Level 2 fire certification, with no toxic dripping during combustion. Specifically designed for flammable and explosive scenarios such as oil tankers and offshore oilfields, it is suitable for key parts like operating platforms and evacuation channels.
| Performance | Phenolic Pultruded Grating | Molded FRP Grating | Steel Grating |
|---|---|---|---|
| Structure | Unidirectional pultrusion; strongest in bearing direction | Bidirectional molded structure | Welded metal structure |
| Load Capacity | Highest among three | Medium | High (affected by corrosion) |
| Stiffness (Long Span) | High stiffness; suitable for long spans | Medium | High but heavy |
| Corrosion Resistance | Excellent | Good | Poor |
| Fire Rating | ASTM F3059 L2 | Basic flame rating | No fire rating |
| Smoke Density | Very low | Medium | Low smoke but fails under heat |
| Toxicity | Very low | Medium | Non‑toxic but loses strength under heat |
| Heat Resistance | Stable at high temperature | Limited by resin type | Loses strength around 600°C |
| Weight | Lightest | Medium | Heaviest |
| Installation Cost | Moderate | Low | High |
Complies with the highest fire and safety requirements.
Pultruded structure provides superior load capacity along the bearing bar direction, ideal for large-span applications with fewer supports.
Phenolic resin ensures minimal smoke generation and excellent safety in enclosed spaces.
Excellent strength-to-weight ratio reduces installation cost.
Performs reliably in offshore, chemical, and humid environments.
