Product introduction
PP Welded Geogrid are warp knitted PP materials welded geogrid,it use PP as raw materials,through extruding to be rib belt which with very high tensile strength,then the belts warp knitted and welded by Ultrasonic welding machine to make it have high tensile strength in both Longitudinal and Transverse direction. This products mainly used for Soil stabilization,road sub-base reinforcement,aggregates confinement and improving the performance of road anti-pressure ability.
