1. The steel-wires of vertical and horizontal ribs of steel-plastic composite geogrid are knitted into webs. The outer coating is finished in one time. The steel-wires and the the outer coating play a coordinating role. The elongation rate at break is low ( less than 3% ).

2. By the treatment to plastic surfaces, the ribs are pressed into rough pattern to strengthen the roughness of the geogrid surface. This could improve the friction coefficient between the steel-plastic composite geogrid and soil. 

3. The width of steel-plastic composite geogrid could reach 6m. The product has effective reinforcement effects.

4. The PP material of steel-plastic composite geogrid could ensure: it won't be eroded by acid, alkali, salt solution or oil under room temperature; It won't dissolved in water or destroyed by microorganisms. Meanwhile, the macromolecule properties of PE could resist aging caused by ultraviolet radiation.

5. The vertical and horizontal ribs cooperate with each other when pressed, and it won't crack or destroy at the nodes. In engineering constructions, the geogrids won't be subjected to ultraviolet and oxygen erosion under compaction by fillings. The geogrids can meet the requirements of permanent project construction.
