Uniaxial Plastic Geogrid
Main Features:
·High Strength and Low Elongation: High tensile strength (>150 kN/m), low elongation (only 2%–5%), and excellent creep resistance
·High Durability: Enhanced with anti-aging agents such as carbon black, offering outstanding resistance to acids, alkalis, corrosion, ultraviolet radiation, and low temperatures (suitable for extreme environments from -45°C to -50°C)
Uniaxial plastic geogrid is a high-strength geosynthetic material made from high-density polyethylene (HDPE) or polypropylene (PP) through extrusion, punching, and uniaxial stretching processes, featuring excellent properties such as high tensile strength, low elongation, corrosion resistance, and anti-aging performance.
Through oriented stretching, the polymer chains in the material are aligned linearly in the direction of applied force, forming a long elliptical mesh structure with uniform distribution and high node strength. The tensile strength can reach 100–200 MPa, surpassing even that of low-carbon steel, enabling the material to effectively withstand and distribute soil stresses.
Ⅰ. Main Features:
