    Manufacture of the material with other physical and mechanical properties is accept edupon a greeing about with a consumer.

  • Typical application:

    the mining mesh of fiber glass is used as inner fencing for sides and roofs of mine tunnels of different purposes, shapes and sizes, including mounting and break-down chambers in the temperature range of -50°С to +50°С.

    Using mining meshes of fiber glass makes it possible to extend service life of support lagging, avoid sparking and accumulating static electricity, substantially simplify mounting the mesh on sides and ceiling, consume lagging more savingly thanks to decrease in overlapping.

  • Advantages:

    • Non-flammable: time of burning after being taken out of Bunsen flame is 0 sec; self-ignition temperature is more than 500оС,
    • Low stretchability (elongation factor at failure is not more than 4%) and thereby generation of swagging pouches with rock and coal inrush is excluded,
    • Durability: depending on customer’s requirements and rigidity of rock, tensile strength is from 40 kN/m to 200 kN/m,
    • Extended service life: the mesh is not rust-prone amidst mining waters and would not degrade in the course of service,
    • Ease of installation: flexible fibres at the core of structure enable lagging of turns, corners without additional mounting,
    • Elimination of sparking and accumulating static electricity,
    • Saving consumption of lagging thanks to decrease in overlapping,
    • Light weight of rolls (starting from 15 kg) enables easy transportation of the material under the conditions of shafts and minings.
