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.

Product Features
1.The intensity is high and the distort is small;
2.The wriggle is small;
3.Anti-corrosive,the life is long,the geogrid take the plastic material as a protector, auxiliary enables it by each kind of assistant to have the antiaging,the oxidation susceptibility again,but acidproof ,alkali,salt and so on adverse circumstance corrosion.Therefore ,the steel modles the earhwork gril to be possible to meet each kind of permanent work100year above use need,and the perfor mance is superior,the size stability is good;
4.The construction is convenient ,the cycle is quickly short.the cost is low;the steel plastic complex geogrid to lay down,joining ,the localization to be easy,to be smooth,avoids overlapping crossover,but reduced the project cycle effectively,saved the building cost of projects by 10%-50%.
