Performance Advantages: The Perfect Combination of High Strength and Low Creep​​

The fiber-plastic composite geogrid, also known as a polyester yarn bundled geogrid, is formed by bundling high-strength, high-toughness, high-modulus polyester yarns into strands and then coating them with a PE protective layer. The core advantage of this material lies in its exceptional mechanical properties. According to industry data, the strength of fiber-plastic geogrids can reach up to 500 kN/m, with some products even exceeding 1000 kN/m. More notably, this material exhibits extremely low creep characteristics. Under a load of 70% of its ultimate strength, the creep deformation of the polyester yarn bundled geogrid is no more than 1% over 100 years, which is significantly lower than that of polypropylene and polyethylene geogrids. This characteristic is crucial for controlling post-construction deformation of embankments and structures, ensuring long-term stability of engineering projects. ​​

Economic Benefits: Reduced Pile Usage and Shorter Construction Cycles​​

The application of fiber-plastic geogrids brings not only technical advantages but also significant economic benefits. In pile-supported reinforced embankments, using high-toughness polyester yarn bundled geogrids can effectively increase the pile spacing, up to a maximum of 3.0 meters. This feature directly translates into cost savings. Engineering data shows that by using this geogrid, the pile spacing can be increased from the conventional 2.0 meters to 3.0 meters, reducing the number of piles required by 50% and lowering overall costs by 30%-40%. Construction efficiency is also significantly improved. Due to the reduction in the total number of piles, construction efficiency can be doubled, and the piling foundation construction period can be shortened to about half of the original time. For large-scale infrastructure projects, this means considerable cost savings and earlier project completion.

​​Application Fields: Wide-Ranging Uses from Highways to Water Conservancy​​

The application range of fiber-plastic geogrids is extremely extensive. In civil engineering, they are used for foundation reinforcement, slope protection, and dam reinforcement. Transportation construction is one of its main application areas. In the construction of transportation facilities such as highways, railways, and bridges, geogrids are used for pavement enhancement and reinforcement. Their high strength and durability effectively withstand the heavy loads from vehicles and trains, extending the service life of the pavement. Water conservancy projects represent another important application area. In hydraulic facilities such as dams, reservoirs, and river channels, geogrids are used for flood control dikes, revetment engineering, and flow control. Their robust structure effectively resists scouring and erosion from water flow. With the rapid development of infrastructure, geogrids, due to their high strength, corrosion resistance, flexibility, factory pre-fabrication, and ease of transportation, are showing a trend of replacing traditional metal strips in reinforced soil applications. ​​

Market Prospects​​

The market for fiber-plastic composite geogrids is continuously expanding alongside the booming development of the infrastructure industry. Against the backdrop of increasing geotechnical projects in highways, railways, water conservancy, and port engineering, the demand for geogrids is showing a growing trend.
