Product introduction
PET geogrid can be used for highway, railway, embankment, abutment, construction road, wharf, revetment, flood control embankment, dam, beach treatment, freight yard, slag yard, airport, sports ground, environmental protection buildings, soft soil foundation reinforcement, retaining wall reinforcement, high slope treatment and other civil works, as well as water conservancy projects exposed to the outer boundary.
PET is the main raw material, two-way welded polyester geogrid made by extrusion, stretching, and welding very high radial secant stiffness value, high resistance to biological and chemical degradation, very high strength under low strain, elongation at the break ≤8%, good filler interlocking effect, and reduced filler usage. Q/CR549.2-2016 Geogrid standard products have been certified by China Railway Inspection and Certification Center, CRCC.
