Ceiling steel-plastic grid for coal mine 1.Mesh width: 4.0/3.0/2.0/1.5m 2.Mesh length:5~25+0.5m 3.Tensile strength:4000N/m
Jizhou ZhongJie Engineering Materials Co., Ltd was established in the year 2000, and mainly manufacture geogrids, geotextile, geomembrane,double-resistance grids for mining, high-pressure oil tubing, waterproof plate, and rubber fender, rubber waterstop belt,etc.
Ceiling steel-plastic grid for coal mine
Steel-plastic geogrids use polypropylene and steel wire as materials, through treatment of anti-static and fire resistance, using extruding,cooling,welding etc techniques, to form square grids with whole structure.

Performance: 1. Anti-static, the average resistance value of grids surface under 1×109Ω;
2. Fire-resistant, under the environment of 760 tempreture, only melt,not to fire;
3. Due to low ribs density, convenient to wash coal;
4. Anti-corrosion; convenient for construction and transport;
5. Strong bearing capacity, hot insulation, sound insulation.
Applications : Steel-plastic geogrids are mainly used in mining as ceiling and shield, and they can act as protecting material of anchor laneway, shoring laneway, anchor spraying laneway and so on. Also can be used as reinforcement materials in mine laneway, slope protecting , underground construction and communication etc projects. It is the optimal replacement product of plastic weaving grids and steel wire grids.
