Uniaxial geogrids are made of macromolecule polymer by the process of being stretched out, formed into lamella, punched regularly and then longitudinal elongated, which enable macromolecule formed into a oriented, lineal, equably distributed uniform ellipsoidal reticulation with intensive node which have higher tensile strength and tensile modul. It should be especially noted that we are able to supply those products with 2 percent to 5 percent tensile rate and a at least 150 Mpa tensile strength so as to give soil a perfect standing and diffusing chain system which enable us be the world leading manufacture in this aspect. These products can be used as reinforcing concrete materials for all kinds of soil. Applications: 1) It is a high-strength structure material, suitable for strengthening highway, road, railway, and airplane lane. Strengthen road base, can effecting distribute loading; Improve stability, loading capacity and usage validity of road base. Prevent material of road base from flowing away and deforming, breaking road base. Bear much more loading capacity. Suitable for various kinds of land soil, saving labor and time construction simple and quick. 2) Suitable for strengthening land-blocking wall of sea and rivers side. Improve loading capacity of land blocking wall. Shorten 1/2 covering land measure of area, extend usage validity reduce maintaining charges. 3) Suitable for strengthening dams and dikes of river. Making stone cage together with grille, prevent dams and dikes from scouring, sinking. Stone cage is permeability, can retard sea waves to attack, improve life of dams and dikes, stone cage can save large-quantity material, labor, shorten construction time. Suitable for protecting fence of orchard, vegetable land, livestock, construction site, convenient and quickly installing, unloading. Good appearance, clear at glance.
