Warp-Knitted Polyester Grilles
Warp Knitted Grille is manufactured using high-strength polyester or fiberglass through warp-knitting technology, offering tensile strength of 50–200 kN/m, creep resistance, and bidirectional load distribution to stabilize soil structures long-term. It resists corrosion and UV degradation, with an outdoor service life exceeding 30 years. Our factory-direct model eliminates middlemen, ensuring strict quality control, consistent product reliability, and 15–30% cost savings. Customizable production (adjustable aperture and strength) and rapid delivery cater to diverse needs. Widely used in highways, dams, mines, and environmental projects, it provides a cost-effective, worry-free reinforcement solution, reducing costs and enhancing efficiency throughout the project lifecycle.
Warp Knitted Grille is engineered using high-strength polyester (PET) or fiberglass through advanced warp-knitting technology. Its unique grid structure features interwoven longitudinal (warp) and transverse (weft) fibers, with reinforced nodes via coatings or thermal bonding to ensure structural integrity and mechanical performance. Compared to traditional extruded geogrids, the warp-knitting process enhances flexibility and fatigue resistance, making it adaptable to dynamic loads and complex geological conditions.
Core Performance Advantages
High Strength & Low Creep: Warp-direction tensile strength ranges from 50–200 kN/m, with long-term deformation rates below 3%, ensuring stable soil reinforcement and preventing settlement or lateral displacement.
Environmental Durability: Polyester fibers coated with PVC or asphalt resist chemical corrosion, UV degradation, and extreme weather, delivering an outdoor service life exceeding 30 years.
Permeability & Soil Retention: Adjustable open-grid apertures (10–50 mm) allow free water flow while retaining soil particles, maintaining structural integrity in drainage-critical applications.
Bidirectional Load Distribution: Uniform stress dispersion minimizes localized pressure, enhancing load-bearing capacity and safety in slopes, embankments, and roadbeds.
Factory Direct Benefits
As a direct manufacturer, we prioritize:
Customization Flexibility: Tailor aperture size, tensile strength, and coating types to meet project-specific requirements for highways, mining, or hydraulic engineering.
Efficient Logistics: In-house warehousing and streamlined delivery systems guarantee rapid response, even for urgent orders.
Key Applications
Transportation Infrastructure: Reinforcement of highway/railway subgrades, airport runways, and bridge approaches.
Hydraulic Engineering: Slope stabilization for dams, riverbanks, and retaining walls.
Environmental & Mining Projects: Base protection for landfills, tailings pond reinforcement, and erosion control.
Industrial Zones: Ground stabilization for port yards and heavy machinery operating areas.
