The grid can be widely used in highways, municipal roads, railways, runways and other subgrade strengthening, road, rail and river shores of reinforced earth retaining wall of reinforced engineering; rivers and dams to enhance the sea; and orchard, vegetable plot, livestock, land, etc. Wai file. This grille is a high molecular polymer through extrusion, and then made vertical or two-way stretch with a tensile strength (> 150Mpa), suitable for all kinds of soil, its performance indicators are better than without the pull - extension of geotextile net is a kind of ideal reinforced reinforcement. The unit has a large output, high efficiency and stable quality, easy operation, etc., is a geotechnical materials and plastic products manufacturers to develop new products, the best choice.
