Mine Grid
High reinforced Polyester Mine Grid is a kind of fake ceiling mesh mainly used for coal mine as well as other mines and underground civil engineering. It adopts high-modulus and high strength long polyester fiber warp knitted and bundled together as its body and then is coated with fire retarding and static conducting material. It is a good substitute for metal mesh, plastic mesh, steel-plastic composite mesh, packing belt mesh and etc.
