This plastic machine, New-type macromolecule compound geomaterial plastic geogrid has the following excellent advantages, like high strength, steady size, rot-resistance, old-resistance because of exclusive physical structure, it is widely used in the fields of irrigation works, highway, railway, airport, coal mine and other project areas.During production, if adding plastic static-resistance agent and master batch of burning-resistance agent, it can also to produce doubledirection stretch and concussion plastic net for mine, which is mainly used in underground work conditions, like mine protect ceiling, hurdle. It is instead of the traditional wire knotting net.
