The two-way plastic geogrid is a square mesh structure product, which can effectively strengthen the subgrade and pavement of highway, railway and airport, and also can be used to wrap stone for reclamation, with good performance and wide use.

The bi-directional plastic geogrid and steel plastic composite geogrid are good materials for subgrade reinforcement, but their use scenarios are different. The two-way plastic geogrid is commonly used in railway subgrade, mainly because there is a great difference in the elongation of the two products. The elongation of the two-way plastic geogrid is 13% - 16%, which is very suitable for use in railway, while the elongation of the steel plastic geogrid is about 3%, which is suitable for use in highway subgrade, but the two cannot be replaced.

The two-way plastic geogrid, one-way plastic geogrid and steel plastic composite geogrid contain carbon black, which can effectively resist radiation and corrosion.

The two-way plastic geogrid and the two-way steel plastic composite geogrid have their own advantages when they are compared. Because the maximum tensile strength of the two-way plastic geogrid can only reach 50 kn / m, and the two-way steel plastic composite geogrid can reach 200 kn / m. therefore, when the weak subgrade is encountered, the advantages of the two-way steel plastic geogrid will be solved The steel plastic composite geogrid also has a greater advantage in the price.

The two-way plastic geogrid and two-way steel plastic composite geogrid have better rigidity and thickness from the appearance, and they are formed into a network structure, which can combine with the soil very well and produce ideal friction and grip force, thus shackle the deformation of the soil and improve the overall performance of the soil. From the perspective of the internal performance of two-way plastic geogrid and two-way steel plastic composite geogrid Both of them have higher tensile strength and lower ductility, which can improve the bearing capacity of soil and the stability of subgrade very well. Moreover, the addition of two-way plastic geogrid and two-way steel plastic composite geogrid to the subgrade of road and railway can reduce the height of subgrade and the earthwork volume, thus speeding up the construction and saving the construction Industrial investment reduces the interference or damage to the environment. Therefore, it is a good material for the benefit of the country and the people.
