■Product Usage
Biaxially stretched plastic geogrid is suitable for various dams and roadbed reinforcements, slope protection, cave wall reinforcement, large airports, parking lots, docks and freight yards, etc. Permanent load-bearing foundation reinforcement.

Plastic geogrid geogrid is a square or rectangular polymer mesh formed by stretching. It can be one-way stretch or two-way stretch depending on the stretching direction during its manufacture. Two kinds. It punches holes in extruded polymer sheets (the raw materials are mostly polypropylene or high-density polyethylene), and then performs directional stretching under heating conditions. The one-way stretched grille is only made by stretching the plate along the length direction, while the two-way stretched grille is made by continuing to stretch the one-way stretched grille in the direction perpendicular to its length.
) br/> Since the polymer molecules of the plastic geogrid will be rearranged and oriented during the heating and elongation process, the bonding force between the molecular chains will be strengthened to achieve the purpose of improving its strength. Its elongation is only %~% of the original plate. If anti-aging materials such as carbon black are added to the geogrid, it can have better durability properties such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
) br/> Bidirectional geogrid
) br/> Bidirectional geogrid is made of high molecular polymer through extrusion, plate forming and punching processes and then stretched longitudinally and transversely. The material has great tensile strength both longitudinally and transversely. This structure can also provide an ideal interlocking system for more effective force bearing and diffusion in the soil, and is suitable for large-area permanent bearings. Foundation
) br/> Unidirectional geogrid
) br/> Unidirectional geogrid is made by extruding a polymer into a thin plate, punching a regular mesh, and then stretching it longitudinally. In this process, the polymer is made into a directional linear state and forms an oblong network-like overall structure with uniform distribution and high node strength. This structure has very high tensile strength and tensile modulus.
