Application
:
  • For covering open channels or areas (waste water treatment systems, industry, agriculture)
  • GRP (Glass Reinforced Plastic) is the material used to build 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)
