    Product characteristics
    1. Compared with traditional grating, steel-plastic geogrid has many characteristics, including higher strength, bearing capacity, corrosion resistance, aging resistance, larger coefficient of friction, uniform pore structure, easy construction process, and long service life.
    2. It can also effectively prevent construction damage caused by construction machinery crushing and destruction, providing a reliable guarantee for engineering construction.

    Characteristics
    1. The steel-plastic composite grating uses high-strength steel wires woven in warp and weft to carry the tensile force and therefore has an tensile modulus at low strains. The longitudinal and transverse ribs work together to maximize the locking effect of the grating on the soil. 2.
    2. The longitudinal and transverse ribs of this grating consist of braided high-strength steel wires, with the outer cladding molded in a single pass, resulting in a synergistic interaction between the steel wires and the outer cladding, and a very low breakage elongation (no more than 3%). Therefore, the main force unit of steel-plastic composite geogrid is steel wire, and the creep characteristics are extremely low.
    3. Through the treatment of the plastic surface in the production process, the rough pattern is processed to improve the roughness of the grating surface, thus increasing the friction coefficient between the steel-plastic composite geogrid and the soil body.
    4. The width of steel-plastic composite geogrid can be up to 6 meters, which can achieve an efficient and economic soil reinforcement effect.
    5. Steel-plastic composite geogrid adopts high-density polyethylene, which is resistant to acid and alkali, salt solution, and oil erosion, and is not subject to water dissolution or microbial attack. Its polymer properties can also resist the aging caused by ultraviolet radiation. When the grating is stressed, the longitudinal and transverse ribs work in concert without pulling apart or breaking at the nodes, thus fully meeting the requirements of permanent engineering construction.
    This grating has a wide range of uses in a variety of engineering applications, including the reinforcement of soft ground foundations such as highways, railways, bridge piers, approach roads, wharves, dams, slag dumps, and other areas such as pavement anti-cracking projects.
    Engineering role
    1. High strength, small creep, adaptable to all kinds of environmental soil, can fully meet the use of high-grade highway in the tall retaining wall.
    2. It effectively improves the embedded locking and biting effect of the reinforced bearing surface, significantly enhances the bearing capacity of the foundation, effectively restricts the lateral displacement of the soil body, and improves the stability of the foundation.
    3. Compared with traditional grating, it has higher strength, bearing capacity, corrosion resistance, aging resistance, larger friction coefficient, uniform pore structure, convenient construction, and long service life.
    4. It is more suitable for deep-sea operation and embankment reinforcement and has solved the technical problems of low strength, poor corrosion resistance and short service life caused by long-term seawater erosion when other materials are used in gabions.
    5. Effectively prevent from being crushed and damaged by machinery during the construction process, thus reducing the occurrence of construction damage.
    Application
    Steel-plastic geogrid can be widely used in various civil engineering projects, including but not limited to highways, railways, embankments, bridge abutments, construction access roads, wharves, berms, flood protection levees, dams, beach management, cargo yards, slag yards, airports, sports grounds, environmental protection buildings, soft ground reinforcement, retaining walls, slope protection and anti-deterioration of pavements, and other engineering projects. Its application in different fields can effectively improve the stability and durability of the project, so it has an important role in civil engineering.
    Design and application
    When geogrid is applied to soft foundation treatment, it is very important to determine the arrangement position and number of layers of geogrid according to the geological condition, and it is also necessary to design the strength of geogrid according to the height of roadbed filling.
    1. When the filling height is more than 4 meters, it can meet the requirements of the industry standard, and the longitudinal and transverse ultimate tension should be not less than 20kN/m.
    2. When the filling height is between 3-4 meters, the longitudinal and transverse ultimate tension of the geogrid should not be less than 40kN/m.
    3. When the filling height is less than 3 meters, the longitudinal and transverse ultimate tensile force of geogrid should not be less than 50kN/m, and the elongation rate should not be more than 4%. It is recommended to use GSZ60-60 type geogrid.
    4. When the geogrid is used in the roadbed filling and excavation combination, it should be used in both directions not less than 40kN/m geogrid, and it is recommended to choose GSZ-60-60 type geogrid.
    For the old road widening new and old road combination part, can be learned from the method of Shenda highway expansion. For the roadbed with filling height over 3m, lay steel-plastic composite geogrid at 20cm from the top of the roadbed, the longitudinal (perpendicular to the route direction) ultimate tensile force should be greater than or equal to 60kN/m, the transverse (parallel to the route direction) ultimate tensile force should be greater than or equal to 20kN/m, and the elongation should not be more than 4%. These recommendations help to ensure that the geogrid can meet the corresponding strength and stability requirements in soft foundation treatment, according to the actual situation for reasonable selection and arrangement.

What Are the Advantages of Steel Plastic Geogrid in Soil Stabilization?
Soil stabilization is a crucial aspect of civil engineering and construction projects, particularly in areas with weak or unstable soil conditions. Steel plastic geogrids offer several advantages in soil stabilization applications, contributing to improved engineering performance, enhanced durability, and cost-effective solutions. 
1. Enhanced Load-Bearing Capacity:One of the primary advantages of steel-plastic geogrids in soil stabilization is their ability to enhance the load-bearing capacity of weak or poorly compacted soils. By distributing applied loads more efficiently, the geogrids reduce stresses on the soil mass, minimizing the risk of settlement and deformation. 
2. Improved Slope Stability:Steel-plastic geogrids play a crucial role in stabilizing slopes and preventing erosion in hilly or mountainous terrain. When installed within the soil mass, the geogrids provide reinforcement that resists the gravitational forces acting on the slope. 
3. Reduction of Soil Erosion:Erosion control is a key consideration in soil stabilization projects, especially in areas prone to runoff and sedimentation. Steel-plastic geogrids help mitigate erosion by stabilizing the soil surface and preventing soil particles from being washed away by rainfall or surface water flow. The geogrids act as a barrier, holding the soil in place and promoting vegetation growth, thereby protecting the integrity of the soil and preventing environmental damage.
4. Flexibility and Conformability:Steel-plastic geogrids offer flexibility and conformability, allowing them to adapt to irregular soil surfaces and terrain contours. This flexibility enables engineers to tailor the reinforcement to specific project requirements, accommodating variations in soil conditions, slope gradients, and site geometries. Additionally, the geogrids can be easily installed around obstacles and existing infrastructure, minimizing disruption to surrounding areas.
5. Resistance to Biological Degradation:Unlike traditional soil stabilization methods such as chemical additives or soil compaction, steel-plastic geogrids are resistant to biological degradation. The polymer matrix and steel reinforcement are inherently durable and immune to degradation caused by microbial activity, organic matter, or root penetration. This resistance ensures the long-term effectiveness of the stabilization measures, even in environments where biological degradation is a concern.
6. Durability and Longevity:Steel-plastic geogrids are engineered for durability and long-term performance in harsh environmental conditions. The high-strength steel components and polymer matrix provide excellent resistance to chemical corrosion, ultraviolet (UV) radiation, and mechanical wear. 
7. Cost-Effectiveness:In many cases, steel-plastic geogrids offer a cost-effective solution for soil stabilization compared to traditional methods. The lightweight and easy-to-handle nature of geogrids simplify installation, reducing labor and equipment costs. Additionally, the long-term performance and durability of geogrid-reinforced structures translate to savings in maintenance and repair expenses over time. 
8. Compatibility with Vegetation:Steel-plastic geogrids are compatible with vegetation, making them suitable for environmentally sensitive areas or projects requiring vegetative cover. The open-grid structure of the geogrids allows for the establishment of vegetation roots, promoting vegetation growth and enhancing soil stability over time. 
9. Versatility in Design:Engineers have the flexibility to design customized reinforcement solutions using steel-plastic geogrids to meet specific project requirements. Geogrids are available in various strengths, sizes, and configurations, allowing for tailored solutions based on soil characteristics, loading conditions, and design objectives. 
10. Sustainable Solution:Steel-plastic geogrids contribute to sustainable soil stabilization practices by minimizing environmental impact and conserving natural resources. The use of geogrids reduces the need for extensive excavation, soil replacement, and chemical additives, preserving natural habitats and minimizing disruption to ecosystems.
