PP welded geogrid

The rib belt of PP welded geogrid is made of high polymer plastic through extrusion and stretching, which has high tensile strength. The intersection points of the vertical and horizontal rib belts are welded by high-frequency ultrasonic to ensure the stability of product quality and guarantee The effective interlocking of the grid grid to the soil. At the same time, the strength of the grid can change the tension of the ribs, and adjust the number of ribs to design different models and specifications. To meet the needs of different projects and various technical indicators.

  • PRODUCT DETAILS
  • Introduce
    The rib belt of PP welded geogrid is made of high polymer plastic through extrusion and stretching, which has high tensile strength. The intersection points of the vertical and horizontal rib belts are welded by high-frequency ultrasonic to ensure the stability of product quality and guarantee The effective interlocking of the grid grid to the soil. At the same time, the strength of the grid can change the tension of the ribs, and adjust the number of ribs to design different models and specifications. To meet the needs of different projects and various technical indicators.
    Performance

    PP welded geogrid has the properties of high strength, low elongation (elongation at break is not more than 12%), and its creep is very small. The grid is reinforced to strengthen the foundation, increase the bearing capacity, reduce uneven settlement, and resist the formation of the soil failure surface. PP welded geogrid has good flexibility. Because the material is stretched by strong force and the transverse rib belt is double-sidedly clamped, even if it cracks, it still maintains the performance of geogrid.
    Coefficient of friction

    The surface of the product is treated and pressed with rough patterns to enhance its roughness. At the same time, the mesh formed by the vertical and horizontal ribs embeds the soil to achieve the best passive resistance to the soil. The width of PP welded geogrid can reach 2-6.5 meters, and the roll length can reach 50 meters (it can also be produced according to user needs).
    Application field
    It can be widely used in highways, railways, abutments, wharfs, slope protection, slag yards, etc., to the reinforcement, reinforcement, reinforcement of weak foundations in engineering construction, as well as the construction of retaining walls and pavement anti-cracking projects.
