White Color PP Mining Geogrid with Flame-Retardant
¨ Mining Grids are especially for underground mine and tunnel applications. The grids have an integrally formed structure with high tensile strength on MD and TD directions. Mining Grids are manufactured from special formula with flame-retardant polymer.
¨ Easy to transport with lightweight.
¨ Easy to install with improve installation efficiency.
¨ Easy to handle with minimized injury during installation
