PP Uniaxial Plastic Geogrid

PP Uniaxial Plastic Geogrid is manufactured from the most proven “punch-and-drawing” techniques with the most sophisticated manufacturing technology. Solid sheets of polymer have apertures removed by punching, and then the sheet is carefully stretched to achieve optimum molecular orientation within the monolithic polymer structure. Therefore high ultimate tensile strengths of up to 300kN/m can be achieved. PP Uniaxial Plastic Geogrid (GeoFanGrid® PPS) is manufactured from High-Density Polyethylene. HDPE Uniaxial Plastic Geogrid (GeoFanGrid® PPS) is manufactured through the process of extruding the sheet, punching the designed holes, and heating while longitudinal stretching.

For more information, please visit triaxial grid.

Material that does not meet GEOFANTEX minimum standards is given a roll number but is rejected and not placed into inventory. The material is identified as scrap and will not be utilized. Material that meets GEOFANTEX minimum standards but does not meet a stricter customer specification is not allocated to that customer but is placed into inventory as GEOFANTEX standard material.

D. Documentation

Individual Quality Assurance Certificates are generated and supplied for each roll of Uniaxial Plastic Geogrid product to include all relevant quality assurance information about the material(s).

Plastic Geogrid in Railway and Highway Construction

Plastic geogrid is mainly manufactured from polypropylene or high density polyethylene, which are all UV stabilized, chemical and biological resistance. The plastic geogrid is mainly used in the construction of roadways, highways, railways, slopes for ground stabilization and subgrade reinforcement. The plastic geogrid is extruded into sheet and then punched into regular mesh pattern and finally stretched. According to the stretched direction, it can be divided into uniaxial plastic geogrid and biaxial plastic geogrid.

Uniaxial plastic geogrid

Uniaxial plastic geogrid, made of high molecular polymer, is extruded into sheet and then punched into regular mesh pattern and finally stretched in the transverse direction. This production can ensure the structural integrity of the geogrid. The main materials of the uniaxial plastic geogrid are high density polyethylene and polypropylene, which are highly oriented and resists elongation when subjected to heavy loads for long period of time.

Uniaxial plastic geogrid is stretched in the transverse direction.
The uniaxial plastic geogrid is usually packed in rolls and the length can be 50m or 100m.

Biaxial plastic geogrid

Similar with the uniaxial geogrid, the biaxial plastic geogrid is extruded into sheet and then punched into regular mesh pattern. But different from the stretching, the biaxial plastic geogrid is stretched in longitudinal and transverse directions. The material of the biaxial plastic geogrid is polypropylene, which is UV stabilized and chemical resistance. Biaxial plastic geogrid is mainly used in the road constructions for soil reinforcement and subgrade stabilization, it can also be used in the mining industries as the ceiling netting.
