This product is mainly used for the protection of coal mine underground mining, and can be used as support material for various roadways such as bolt roadway, support roadway and anchor spray roadway. When used in a false top, the two layers are used in combination.
The steel-plastic geogrid is made of high-strength steel wire (or other fiber), specially treated, with polyethylene (PE), and other additives, and it is extruded into a composite high-strength tensile strip with rough pressure on the surface. The pattern is a high-strength reinforced geotechnical belt. The single belt is formed by longitudinal or transverse spacing at a certain interval or by clamping, and is welded by a fusion welding technique of special strengthening bonding to form a reinforced geogrid.
