    *warp-knit mesh comprises two perpendicular systems of rovings or glass yarns interknit with a polyester yarn. Thanks to uniform arrangement of warp yarns and weft yarns in warp-knit mesh (absence of bends in points of yarns intersection), there are improved tensile properties, evener surface texture of mesh and identical values of tensile strengths along warp and weft.

     

    Manufacture of the material with other physical and mechanical properties is accepted upon agreeing about with a consumer.

  • Typical application:

    SPA fiberglass mesh is intended for reinforcing sand discs and other similar purposes.

  • Advantages:

    • increased strength,
    • inproved adhesion to impregnating compounds.
