Steel-plastic geogrid

Steel-plastic composite geogrid

Steel-plastic composite geogrid, made from high-strength steel wire (or other fibers) treated in a special manner, combined with polyethylene (PE) or polypropylene (PP), and with the addition of other additives, is extruded to form a composite high-tensile tensile strip with a rough embossed surface. This strip, when woven or laid in a specific pattern with longitudinal and transverse spacing, and bonded using a special reinforced welding technique, forms a reinforced geogrid.

Characteristics of steel-plastic composite geogrid：

1. The tensile force of the steel-plastic composite grating is carried by the high-tensile steel wires woven in warp and weft, generating a high tensile modulus under low strain capacity. The longitudinal and transverse ribs work synergistically, fully utilizing the interlocking effect of the grating on the soil mass.

2. The longitudinal and transverse ribs of the steel-plastic composite mesh are woven from steel wire, with the outer wrapping layer formed in one piece. The steel wire coordinates with the outer wrapping layer, resulting in a low elongation rate (not exceeding 3%). The main load-bearing element of the steel-plastic composite geogrid is the steel wire, with a low creep rate.

3. By treating the plastic surface during the production process, we press rough patterns to enhance the roughness of the格栅 surface, thereby increasing the friction coefficient between the steel-plastic composite geogrid and the soil mass.

4. The width of the steel-plastic composite mesh can reach 6 meters, offering an economical reinforcing effect.

5. The high-density polyethylene used in the steel-plastic composite grid ensures that it will not be eroded by acids, bases, salt solutions, or oils at room temperature; nor will it be affected by water dissolution or microbial attack. Additionally, the high molecular performance of polyethylene is sufficient to resist aging caused by ultraviolet radiation. The grid's longitudinal and transverse ribs work together under stress, preventing node cracking or damage. In actual engineering, after the filling material is compacted, it remains unattacked by ultraviolet light and oxygen, thus fully meeting the requirements for . engineering construction.

Steel-plastic geogrid engineering application fieldsRoad, railway, bridge abutments, approach roads, docks, dams, spoil yards, etc., involving soft soil foundation reinforcement, retaining walls, and road crack resistance projects.

Engineering Application Features of Steel-Plastic Geogrids：

High strength, low creep, adaptable to various environmental soils, fully meets the requirements for tall retaining walls in high-grade highways.

2. Significantly enhances the interlocking and gripping action of reinforced bearing surfaces, strengthens the foundation's bearing capacity, effectively restricts lateral displacement of soil mass, and improves the stability of the foundation.

3. Offers superior features such as increased strength, higher load-bearing capacity, corrosion resistance, anti-aging properties, large friction coefficient, uniformly distributed holes, ease of installation, and a longer service life compared to traditional gratings.

4. More suitable for deep-sea operations and embankment reinforcement, it fundamentally solves the technical problems such as low strength, poor corrosion resistance, and short service life caused by stone baskets made of other materials due to long-term erosion by seawater.

5. Effectively prevents construction damage caused by machinery crushing and destroying during the construction process.
