The steel plastic composite false roof net used in coal mine underground refers to a mesh product formed by wrapping carbon spring steel wire with polyvinyl chloride resin and surface treatment. The characteristics of high strength and stable performance can ensure its anchoring strength in various environments< Br> The steel plastic composite false roof net used underground in coal mines is suitable for layered mining in thick and extra thick coal seams, as well as for roof protection of single coal seam broken roof to prevent goaf gangway and roadway support; It can also be used for supporting and anchoring projects such as tunnels, highway slope protection, building seismic reinforcement, foundation and component anchoring. The excellent corrosion resistance of plastic and the high strength formed by wrapping steel wire can ensure its support strength in various environments, and it is easy to operate and use. It is an ideal product to replace diamond shaped metal false top nets< Br> Steel plastic composite false roof net, diamond shaped metal net, warp and weft net, resin anchor rod and anchoring agent, emulsified oil for hydraulic support (column) used underground in coal mines< Br> Our group has been engaged in the production of coal mine support products for several years and has won high praise from customers. Our company strives for survival through quality and development through innovation. We have patented products, such as steel plastic composite false roof nets used underground in coal mines, with a large  coefficient of over 25% (compared to diamond shaped metal nets * * 25%), making them the best mesh for coal mine support< Br> Product performance characteristics
1. The elongation rate of low extension products is small, with a measured data of 4.1%, effectively avoiding the phenomenon of "net pockets" in actual use< Br> 2. The surface of corrosion-resistant products is made of corrosion-resistant modified plastic, which will not rust or fail due to corrosion after long-term use, ensuring long-term protective effects< Br> 3. The lightweight product weighs approximately 0.9-1.3 kilograms per square meter, which is only about one-third of the size of the metal protective mesh of the same specification. The size can be freely cut, making it easy for users to purchase, manage, and store, as well as for on-site management. The product has good flexibility, reduces the labor intensity of workers, and can effectively improve work efficiency< Br> 4. The tensile strength of a single mesh belt with 8 high-strength steel wires is ≥ 4000N, and the strength reaches or exceeds that of the same type of metal mesh< Br> 5. The technical indicators of * * dual anti (anti static performance, flame retardant performance) are advanced, and * * are suitable for underground use< Br> 6. The price is lower than that of the same type of metal mesh, which can effectively reduce the cost of mine support< Br> 7. Other modified outer plastic layers have stronger affinity with concrete, which can enhance the strength of shotcrete tunnel support and have strong shear resistance. They effectively overcome the limitations of full plastic mesh in practical use and have a wide range of applications< Br> Product Usage
This product is mainly used as a false roof and support material for layered mining of thick coal seams in coal mines. It can also be used as a support material for various tunnels such as anchor bolt tunnels, support tunnels, anchor spray tunnels, etc. It can also be used as an anchoring and strengthening material for other mining tunnel engineering, slope protection engineering, underground civil engineering, and traffic road engineering. It is an excellent substitute for plastic textile mesh and steel wire mesh< Br> Technical specifications
