ATECH SW-U series geogrids are specifically designed for improved performance in soil reinforcement applications where strength develops uniaxially. SW-U geogrids are made of high strength polyester yarns and glass fibers coated by a carbon black stabilized polyethylene,that is a whole new weaving technique in different materials between 2 axles(MD/XD) in Taiwan. So this technique shows the tensile strength at 2% strain is more rigid and competitive. ATECH SW-U geogids are packed in rolls, roll width is 3.7meters ;roll length is 100meters and wrapped with black PE film.
