Unidirectional geogrid can be divided into two categories according to material, namely the unidirectional polyethylene geogrid and unidirectional polypropylene geogrid. It can also be divided according to tensile force, namely TGDG30KN, TGDG40KN, TGDG50KN, TGDG60KN, TGDG80KN, TGDG90KN, TGDG100KN, TGDG110KN, TGDG120KN, TGDG150KN, TGDG200KN.
At present, there are two standard for geogrid, namely the national standards and industry standard of Ministry of Communications. The former is for the product of integral stretching geogrid. The latter is for the product of various kinds of geogrid. You can check the two standards.
The technical parameters of unidirectional geogrid can be divided into two categories. Unidirectional polypropylene geogrid is usually used in the project of reinforcement or ground treatment. Specification： TGDG80
The polyethylene product is usually used in the construction of reinforced soil retaining wall or abrupt slope. Specification： TGDG80 (HDPE). Check the national standard if there is something not understood. GB\T17689-2008
