Plastic Steel Reinforcement Earthwork Biaxial Geogrid Subgrade Stabilization
Pp Biaxial Plastic-Steel Reinforcement Earthwork Geogrid Subgrade Stabilization
HQ1: Typical Geogrid
What is Geogrid?
Plastic geogrid is a square or rectangular polymer mesh formed by stretching. It can be divided into unidirectional stretching and biaxial stretching according to the different stretching directions during its manufacture. It is punched on the extruded polymer plate (most of the raw materials are polypropylene or high-density polyethylene), and then directionally stretched under heating conditions. single
The upward stretching grid is only made by stretching along the length of the plate, and biaxial stretching
The grating is made by stretching the unidirectional stretching grating in the direction perpendicular to its length.
