A unidirectional geogrid is a product mainly made of high molecular polymer, supplemented with certain UV-resistant and anti-aging additives. Through unidirectional stretching, the originally randomly distributed chain molecules are reoriented and aligned into a linear state, then extruded into a thin plate and punched into a regular honeycomb pattern.Then, a high-strength geosynthetic material is stretched longitudinally. This process orients the polymer molecules into a linear state, forming a uniform, high-node strength, elongated oval mesh structure. Due to the reorientation of the polymer's high molecular weight chains during the heating and extension process in the manufacturing of plastic geogrids, the intermolecular bond strength is enhanced, thereby increasing its strength. Its elongation rate is only 10% to 15% of the original sheet. If carbon black or other anti-aging materials are added to the geogrid,Can provide excellent resistance to acids, alkalis, corrosion, and aging, etc., in terms of durability. The steel-plastic geogrid is made of high-strength steel wire (or other fibers) that has been specially treated, compounded with polyethylene (PE), and enhanced with other additives. Through extrusion, it forms a composite high-tensile tensile strip with a rough embossed surface, which is known as a high-strength reinforced geotextile tape. From this single strip, further processing...Reinforced geogrids are formed by welding the junction points using a special reinforced adhesive welding technique, with the fabric woven or laminated at a certain spacing. The polymer mesh materials, formed through stretching and having square or rectangular shapes, can be either unidirectional or bidirectional stretched, depending on the stretching direction during manufacturing. They are produced by punching holes in polymer sheets (usually made from polypropylene or high-density polypropylene) that have been extruded, then stretched in a directional manner under heat conditions. Unidirectional stretched grids are stretched only along the length of the sheet, while bidirectional stretched grids are further stretched perpendicular to the original length.
