Engineered for unparalleled precision, our Biaxial Stretching GeoGrid Production Line fabricates PP/PE geogrids with superior tensile strength for roadways, soil stabilization, and infrastructure reinforcement. Featuring fully automatic, computerized control and deep-channel twin-screw extrusion, these grids deliver optimized load transfer, enhanced erosion resistance, and rot- and ageing-resistant durability.
Certified to CE, ISO 9001, and SGS standards, its twin-screw deep-channel extruder with 1 450–2 200 mm die-head widths delivers up to 300 double-direction geogrid sets per month, with high-strength, rot- and aging-resistant PP/PE output.
Our production line integrates three precision stages—sheet extrusion, mesh punching, and biaxial stretching—into a single, continuous flow:
1. Sheet Extrusion
Twin-screw, deep-channel screws melt and homogenize PP/PE into a uniform film.
2. Mesh Punching
Precision die-heads system produces 5 × 5 mm to 50 × 50 mm mesh patterns with quick-change tooling.
3. Biaxial Stretching
Single- and double-direction stretching optimizes tensile strength and dimensional stability.
By integrating these stages in a single, fully automatic computerized line, you get consistent grid geometry, repeatable mechanical properties, and maximum uptime—exactly as Tongjia specifies.
The whole system design software to optimize aerodynamic fluid, symmetric multi-group heat exchange heating fan, adjustable air flow and temperature uniformity, precise temperature control system to ensure product heating temperature uniformity.
Lay 3D Geonet between foundation and road bottom foundation, used in drainage water between road ground and road bottom ground, can postpone the road life.
In the cold weather condition, lay 3D laminating Geonet can reduce soil frost leave.
The patented technology includes an oil thermostat system with multiple rolls, designed to stretch materials lengthwise in multiple stages for precise shaping and consistency.
Increases pavement load-bearing capacity, minimizes cracking, and prolongs service life.
Enhances subgrade stiffness, guards against erosion, and strengthens retaining structures.
Boosts trackbed rigidity, equalizes ballast loads, and prevents settlement for reliable rail operations.
