Heavy duty diamond mesh coal mine support hook mesh galvanized iron wire woven protective net

Description :

  Diamond mesh is a mesh structure product woven from metal wires through specialized machinery, mainly used to meet the safety protection needs in mining roadway support, slope protection, and isolation enclosures. In the industrial and mining field, it is often referred to as a hook and loop net or warp and weft net, which has good flexibility and impact resistance due to its unique spiral curling structure. Typical working conditions include roof support in underground coal mine tunnels, initial support after tunnel excavation, and slope reinforcement in open-pit mines. This product can effectively disperse external impact forces, prevent crushed stones from falling, and ensure the safety of the work area. As a basic protective material, diamond mesh is suitable for various complex terrains and harsh environments, and is an indispensable basic consumable in industrial and mining accessories.

  In terms of specifications, diamond shaped mesh is usually made of low-carbon steel wire, stainless steel wire or aluminum alloy wire as raw materials, and the surface is treated with galvanizing, spraying or dipping to enhance corrosion resistance. The common mesh size range is between 30mm and 100mm, and the wire diameter is usually between 2.0mm and 4.0mm, which can be customized according to engineering requirements. Refer to GB/T 5330-2003 for industrial metal wire woven square hole screen mesh or related mining support material standards when implementing standards. The production process adopts crochet technology, with a flat mesh surface, uniform mesh holes, beautiful and practical appearance, and features such as anti slip, wear-resistant, anti-corrosion, and long service life. High tensile strength, low shrinkage rate, stable overall structure, able to adapt to a certain degree of foundation settlement without fracture, ensuring long-term reliability.

  When selecting, it is important to consider the degree of corrosion in the operating environment and the required impact strength. For damp or chemically corrosive mine environments, it is recommended to use diamond shaped mesh made of hot-dip galvanized or stainless steel materials; For temporary enclosures or dry environments, galvanized or black wire materials are sufficient to meet the requirements. Attention should be paid to the difference between diamond mesh and welded mesh. Diamond mesh has better flexibility and is suitable for laying on irregular surfaces, while welded mesh has stronger rigidity and is suitable for flat fixation. If used for high drop slope protection, it is necessary to choose specifications with thicker wire diameter and smaller mesh size to increase interception capability. When purchasing, details such as mesh tolerance, wire diameter deviation, and roll weight should be clearly defined to avoid installation difficulties or inadequate protective effects caused by specification deviations.

  When installing diamond shaped mesh, it should be ensured that the anchor rods or fixing points are evenly distributed and the tension is moderate to avoid protection failure caused by too loose or deformation of the mesh surface caused by too tight. In daily maintenance, it is necessary to regularly check whether the mesh surface is corroded, broken or loose, especially in rainy seasons or highly corrosive environments. Local damage should be promptly repaired to prevent the expansion of the damaged area. When used underground in coal mines, it is necessary to regularly clean the accumulated coal dust and debris on the mesh surface, maintain smooth ventilation, and reduce fire hazards. Proper installation and maintenance can significantly extend the service life of diamond mesh, reduce replacement frequency, thereby saving long-term operating costs and ensuring the sustained stability of slope or support systems.
