mastaGRID® Mining Geogrids are made from punched and extruded polypropylene (PP) with an additional FRAS (Flammability Resistance & Anti-Static) coating.

mastaGRID Mining Geogrids are an ideal substitute for traditional steel mesh and other non-FRAS coated materials in long wall mining applications such as:

  • Long wall shield recovery screens
  • Mine roof & rib control
  • Temporary tunnel support
  • Subgrade improvement

Applications:

  • Recovery Screens
  • Mine Rood
  • Rib Control
  • Temporary Tunnel Support
  • Subgrade Improvement

2. Nominal Value(s).
3. True resistance to elongation when initially subjected to a load determined in accordance with ASTM D6637 without deforming test materials under load before measuring such resistance or employing
“secant” or “offset” tangent methods of measurement so as to overstate tensile properties.
4. Expressed as a comparison of GRI-GG2 strength to GRI-GG1 strength of the same sample.
5. Resistance to bending force determined in accordance with ASTM D1388 mod.
6. Flammability resistance determined from vertical and horizontal flame in accordance with 30 CFR, Part 7, Subpart A & B and ASTP5011-Standardized Small Scale Flame Test Procedure for the Acceptance
of Roof-Rib Grid.
7. Roll widths of 1.5-3.9m and lengths of up to 100m are available to order.
