Warp-Knitted Polyester Geogrid

Warp-knitted polyester grid is a new type of high-quality roadbed reinforcement geotechnical base material, which uses high-strength polyester fiber or polypropylene fiber as raw material, through warp-knitted directional weaving, and treated with special process of diffusion rubber coating.
