Fiberglass geogrid is a semi-rigid product made of high-strength alkali free glass fibers that are woven into a mesh substrate through warp knitting technology and surface coated. It has high tensile strength and low elongation in both warp and weft directions, and has excellent performances such as high temperature resistance, low cold resistance, aging resistance, corrosion resistance, etc. It is widely used in the reinforcement of asphalt pavement, cement pavement and subgrade, and engineering projects such as railway subgrade, embankment slope protection, airport runway, sand prevention and control.
