Chuzhou Two-Way Plastic Grating Specifications and Prices

Polymers netting formed into a square or rectangular shape through stretching.The product can be categorized into unidirectional and bidirectional stretching based on the stretching direction during manufacturing. It involves punching holes into polymer sheets (usually made of polypropylene or high-density polypropylene) that have been extruded, followed by directional stretching under heating conditions. Unidirectional stretching grids are stretched only along the length of the sheet; bidirectional stretching grids are made by further stretching the unidirectional grids perpendicular to their length. Due to the reorientation of polymer macromolecules during the manufacturing process, which strengthens the intermolecular bond forces as they extend and rearrange upon heating,Achieved the purpose of enhancing its strength. Its elongation rate is only 10% to 15% of the original material. By adding anti-aging materials like carbon black to geogrids, they can possess excellent resistance to acids, alkalis, corrosion, and aging. Mining geogrids, also known as double-stretched plastic net false ceiling used in underground coal mines, are abbreviated as false ceiling net. Mining geogrids are specifically designed and manufactured for false ceiling support and gangway support during underground coal mining operations. They are made by using several high polymer resins and adding other modifiers, followed by heating.Manufactured through processes such as extrusion, forming, punching, stretching, shaping, and winding. Mine-grade geogrids, compared to metal woven mesh and plastic braid mesh, feature light weight, high strength, isotropy, antistatic properties, corrosion resistance, and flame retardancy. They are a new type of mesh material used for underground coal mine support engineering and civil engineering projects.
