At the present time, TMP America manufactures only punched-and-drawn biaxial (BX) geogrids at its plant in Alpharetta, GA.
BIAXIAL (BX) GEOGRIDS
BX geogrids are principally manufactured from Polypropylene (PP) granules. The polymer is first extruded to form a plastic sheet, perforated using a high-impact punch press and finally stretched in orthogonal directions within specialized ovens. The stretching process results in the alignment of the PP chain molecules and imparts the high stiffness at low strain characteristics associated with BX geogrids.
