The high-density polyethylene used in the steel plastic grid can ensure that it will not be eroded by acid, alkali, salt solution or oil under normal temperature; it will not be damaged by water dissolution or microorganism. At the same time, the polymer properties of polyethylene are enough to resist the aging caused by ultraviolet radiation. After the grid is stressed, the longitudinal and transverse ribs work together, and there will be no crack or damage of nodes. However, in the actual project, after compaction of the filler, it is not eroded by ultraviolet light and oxygen, so it can completely meet the requirements of permanent project construction.

The steel plastic geogrid is made of high strength steel wire (or other fiber), through special treatment, polyethylene (PE), and other additives, through extrusion to make it into a composite high-strength tensile strip. The reinforced geogrid is formed by welding the joint points of the single belt, which is arranged longitudinally and transversely according to a certain distance or by clamping, using a special strengthened bonding fusion welding technology.

 Product features:

1. The tensile force of the steel plastic geogrid is borne by the high-strength steel wire woven by warp and weft. Under the low strain capacity, the tensile modulus of the geogrid is very high. The longitudinal and transverse ribs work together to give full play to the role of the grid in the soil.

2. The steel wire of the longitudinal and transverse ribs of the steel plastic geogrid is weaved into a net by warp and weft, and the outer wrapping layer is formed at one time. The steel wire and the outer wrapping layer can coordinate, and the elongation at failure is very low (no more than 3%). The main stress element of steel plastic composite geogrid is steel wire with very low creep.

3. Through the treatment of the plastic surface in the production process, rough patterns are pressed to enhance the roughness of the grid surface and improve the friction coefficient between the steel plastic composite geogrid and the soil.

4. The width of steel plastic geogrid can reach 6 m, which can achieve high efficiency and economic reinforcement effect.

5. The high-density polyethylene used in the steel plastic geogrid can ensure that it will not be eroded by acid, alkali, salt solution or oil under normal temperature, and will not be damaged by water dissolution or microorganism. At the same time, the polymer properties of polyethylene are enough to resist the aging caused by ultraviolet radiation. After the grid is stressed, the longitudinal and transverse ribs work together, and there will be no crack or damage of nodes. In the actual project, after the compaction of the filler, it is not exposed to ultraviolet light and oxygen.

6, corrosion resistance, long life: steel plastic geogrid with plastic material as protective layer, supplemented by various auxiliaries to make it have anti-aging, oxidation properties, acid, alkali, salt and other harsh environment corrosion. Therefore, the steel plastic geogrid can meet the needs of all kinds of permanent projects for more than 100 years, with excellent performance and dimensional stability.

7. The construction is convenient and fast, with short period and low cost: the steel plastic geogrid is laid, lapped, positioned easily and leveled, avoiding overlapping and crossing, effectively shortening the project period and saving 10% - 50% of the project cost.

 Product engineering function:

1. High strength, small creep, suitable for all kinds of environmental soil, can completely meet the use of high-grade highway retaining wall.

2. It can effectively improve the embedment and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

3. Compared with the traditional grid, it has the characteristics of high strength, strong bearing capacity, anti-corrosion, anti-aging, large friction coefficient, uniform hole, convenient construction and long service life.

4. It is more suitable for deep sea operation and bank reinforcement, and fundamentally solves the technical problems of low strength, poor corrosion resistance and short service life caused by long-term seawater erosion of gabions made of other materials.

5. It can effectively avoid the construction damage caused by the rolling and damage of machines and tools in the construction process.

The above is a summary of the characteristics and engineering functions of the steel plastic geogrid
