Geogrid is a main geosynthetic material, and compared with other geosynthetic materials, it has unique properties and effects. It is commonly used as the reinforcement for reinforced soil structures or composite materials, etc.
Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids, and polyester warp-knitted polyester geogrids. Grids are two-dimensional grid-like or three-dimensional grid screens with a certain height made of high molecular polymers such as polypropylene and polyethylene through thermoplastic molding or compression molding. When used in civil engineering, they are called geogrids. Product features: high strength, small deformation; small creep; corrosion resistance, long service life: Steel-plastic geogrids use plastic materials as a protective layer, supplemented by various additives to make them have anti-aging and oxidation properties, and can resist corrosion in harsh environments such as acid, alkali, and salt. Therefore, steel-plastic geogrids can meet the service requirements of various permanent projects for more than 100 years, with excellent performance and good dimensional stability.
Convenient and quick construction, short cycle, low cost: Steel-plastic geogrids are easy to lay, overlap, and position, and are flat, avoiding overlapping and crossing, which can effectively shorten the project cycle and save 10%-50% of the project cost. This product is mainly used for rib protection during underground coal mining, and can be used as a supporting material for various roadways such as bolt roadways, supporting roadways, and shotcrete roadways. When used as a false roof, it is used in combination with two or more layers.
