PP Plastic Uniaxial Geogrid

    Description

    Uniaxial geogrid is a kind of high-strength structural materials for highways, municipal roads, railways and other subgrade enhancement

    Introduction of PP Plastic Uniaxial Geogrid

    PP Plastic Uniaxial Geogrid is extruded in HDPE or PP. It can provide high strength in one direction and are typically used on earth walls and slopes under long term high loading, and slip repairs. These uniaxial plastic geogrid carry large tensile loads applied in one direction (along the roll), and their open aperture structure interlocks with natural fill materials. 

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.
