50X50mm Heavy Duty Mesh Size Fiberglass gritted Outdoor Drain Grate
The popularity of fibre reinforced polymer (FRP) grating is slowly gaining momentum as they offer numerous advantages over customary materials for use in platforms and walkways, particularly within harsh and corrosive environments.


FRP molded grating is made of vertical and horizontal continuous fiberglass fully soaked in unsaturated polyester resin giving perfect bi-directional mechanical properties. Combining the lasting non-slip properties, the resilience to corrosion and the proven long term cost advantages, molded gratings provide the ultimate in reliable performance.
| Grating Type | Resin Type | Description | Grating Type | Application |
| Type V | Vinyl Ester | Superior Corrosion Resistance and Fire Retardant | 110℃ | Environment with serious corrosion issues |
| Type I | Isophthalic Polyester Resin | Industrial Grade Corrosion Resistance and Fire Retardant | 105℃ | Environment of middle concentration inorganic acid, alkali |
| Type O | Orthophthalic Polyester Resin | Moderate Corrosion Resistance and Fire Retardant | 70℃ | For use in waster,waster or air-ageing application,light industrial application where the environment is moderate |
| Type P | Phenolic Resin | Low smoke and superior Fire Retardant | 180℃ | Offshore and subway application where fire resistance, low smoke and low toxic fumes are critical |
