Geogrid for mining
Mine geogrid is made by extruding and stretching with modified polypropylene and other high-molecular polymers as main materials. It is suitable for false roof support and roadway support in coal mines and metal mines. It can also be used for subways, tunnels and other projects.
Features:
1. High strength: high strength, corrosion resistance, can effectively replace metal mesh;
2. Low weight: it can reduce labor intensity, improve work efficiency, and it is easy to install and use;
3. Safety: antistatic, flame retardant, can effectively prevent the electrostatic sparks.
Application:
It is suitable for false roof support and roadway support in coal mines and metal mines. It can also be used for subway, tunnel and other engineering support.
