Application:
- For covering open channels or areas (waste water treatment systems, industry, agriculture,...)
- GRP (Glass Reinforced Plastic) is the material used to make gratings. These are polyester fibers soaked into special plastic resins. Resins used can be based on:
- Vinyl-ester (highly resistant on different material corrosion)
- Phenol (fire and high temperature resistance)
- Epoxy (special electric properties)
- Acryl (low smoke emission)
