Common Queries

Frequently Asked Questions

Detailed technical and commercial answers from our composite product engineering team.

Our grit is embedded directly into the resin matrix during the thermal curing process, rather than glued onto the surface post-production, ensuring permanent bonding even under heavy foot traffic.

Yes. We manufacture covered FRP gratings (chequered or grit-top plate laminated over molded grating) to contain chemical vapors and odors in drainage channels.

Yes, because fiberglass gratings weigh 75% less than cast iron or steel, a single technician can easily remove trench panels for cleaning without hoist equipment.
