The Steel-Plastic Composite Geogrid is a mesh-structured geosynthetic material manufactured primarily from high-strength steel wires (or other metal fibers) and polyethylene plastic. It is produced through specialized processes including plastic coating, stretching, and embossing. This product effectively combines the high strength and low creep properties of metal with the corrosion resistance and durability of plastic, forming a high-performance reinforced bearing network.Its primary functions are to distribute loads and enhance the tensile strength and overall stability of soil masses.
Performance
Steel-Plastic Composite Geogrid has the following characteristics：
Very High Tensile Strength: Utilizing high-strength steel wires as its core, its tensile strength far exceeds that of plastic geogrids and geotextiles, typically ranging from 80 kN/m to over 200 kN/m, or even higher.
Very Low Creep: Steel wire exhibits minimal creep deformation, ensuring the geogrid does not experience significant relaxation or deformation under long-term loading. This provides a high safety factor and long service life.
Excellent Node Strength: The unique plastic coating and forming process results in extremely high peel resistance at the nodes (where the wire and plastic meet), ensuring cooperative force transmission between longitudinal and transverse ribs and eliminating concerns about welded node fatigue.
Superior Durability and Corrosion Resistance: The outer plastic layer completely isolates the steel wires from corrosive environments (acids, alkalis, salts, water, atmosphere), providing dual corrosion protection. The designed service life can extend for decades.
Powerful Interlocking and Biting Effect: The rough, embossed surface and regular mesh structure generate strong friction and interlocking forces with soil and aggregate, effectively restricting lateral displacement of the soil mass.
Easy Installation: Supplied in rolls, the product is lightweight, easy to cut, lay, and overlap, leading to high construction efficiency and significantly reduced project timelines.
Application
Steel-Plastic Composite Geogrid is primarily used in engineering fields requiring high-strength reinforcement:
Highway/Railway Engineering: Reinforcing soft soil subgrades and preventing differential settlement; reinforcing embankments and steep slopes to improve stability; addressing transitions between old and new road sections, and approach embankment settlement behind bridge abutments.
Retaining Walls and Steep Slopes: Used as reinforcement to construct mechanically stabilized earth (MSE) walls and steep slopes, offering an alternative to traditional gravity walls, saving space and cost.
Port, Harbor, and Coastal Engineering: Reinforcing breakwaters, revetments, and backfill behind quay walls to enhance overall stability.
Large-Scale Site Foundations: Used in sites requiring high bearing capacity, such as airports, freight yards, parking lots, and logistics parks.
Geohazard Prevention: Steel-Plastic Composite Geogrid is used in landslide control and reinforcement of mine tailings dams.
