Product Introduction
?
PP Uniaxial Geogrid is made of high molecular polymer after extruded and laminated and punched into regular mesh before longitudinal stretching. This process makes high molecule in direct line state in oblong oval net structure with uniform distribution and high node intensity. This structure has rather high tensile strength and stretch modulus, especially our products of this kind have superior world class tensile strength and stretch modulus with extensibility between 2% and 5%. The soil offers ideal force carrying and diffusing chain system. It has large tensile strength (>150Mpa), and is suitable for different kinds of soil. It is a prevailing reinforcement material.

Product Features
1. Uniaxial high tensile strength, good creep resistance, chemical nature is stable;
2. The friction coefficient with gravel is large.

Product Function
?
1. Uniaxial geogrid is a kind of high-strength structural materials for highways, municipal roads, railways and other subgrade enhancement;
2. It is applied in the enhancement of dam rivers and the sea dike;
3. It is applied in the fence of orchards, vegetable, livestock, land, et. The use is safe and convenient, and conducive to disassembly, elegant appearance;
4. It is applied in the earth retaining and wall reinforcement works of highways, municipal roads, railways, rivers and along the coast;
5. It is mainly used for retaining walls, abutment, slope works and so on;
6. Retaining walls and abutment are force structure which assume all external load, the active earth pressure, the upper part of the structure of the dynamic load, temperature stress and so on, in a larger long term reinforcement under tension, as well as the effect of repeated dynamic loading, the molecular structure of materials fatigue, occurred in the performance of attenuation and speed up the aging grid. In order to avoid deformation resulting from reinforcement material creep, it is better to select a high-density polyethylene(HDPE) as raw materials for uniaxial geogrid.
