Product Introduction
Polyester geogrid known as PET grid is woven by high strength polymer yarns as per desired mesh sizes and strength from 20kn/m to 800kn/m(biaxial type),40-25kn/m to 600-400kn/m(uniaxial type).
Woven pet grid is created through interlacing, usually at right angles, two or more yarns or filaments.
Exterior of pet grid is coated with polymer or nontoxic substance material for uv ,acid and alkali resistance and prevents the bio-decomposition.
Pet grid is widely introduced to the various fields of civil engineering, transportation engineering, and environment issues. The reinforced steep slopes , reinforced retaining earth walls, reinforced embankments, reinforced abutments and piers are typical applications where geogrids are used. The resulting grid structure possesses large openings that enhance interaction with filling material.
