PET two-way polyester stretch welding geogrid is polyester for main ingredient, join anti-aging agent and other additives, after low multiple mechanical drawing into refined rib, then rib according to plane jinwei square, the ultrasonic welding the rib junction formation of geogrid. Product features: high strength, tensile rate is small, the creep coefficient small. Heat resistance range - 70 degrees to 180 degrees Celsius, resistance to ultraviolet ray, microbiological corrosion good performance. Applicable scope: retaining wall reinforcement, soft soil foundation treatment, high slope, water conservancy engineering, etc. Product specifications: mesh size is in commonly 8 cm to 12 cm between. 6 meters wide, roll long unlimited.

According to June 25, 2006 issued by the ministry of railways TB10118-2006 < < railway subgrade geosynthetics application design standard > > provisions (37 pages) that the description: polyester engineering plastics (commonly known as PET) that plastic tensile geogrid, its belong to rigid material, the production process through low multiple mechanical drawing, high strength tensile rate is small, the creep coefficient is small, the value is 1.67, heat resistance range - 70 degrees, 180 degrees Celsius, resistance to ultraviolet ray, microbiological corrosion performance, good acid and alkali performance slightly lower than PP, is the ideal geosynthetics materials. It is suitable for retaining wall reinforcement, soft soil foundation treatment, high slope protection and is easily exposed to the outside of the water conservancy engineering.
