HAILIDE?ZHGQ is a polyester geogrid, composed of high molecular weight, high tenacity multifilament polyester yarn, and has a polymeric coating. Polyester yarns must have minimum average molecular weights of 25,000 and a maximum carboxyl end group of 30. HAILIDE ZHGQ is characterised by high strength at low elongation, excellent creep behavior and durability in civil engineering applications.
