Product Features

  • Net holes are easy for net blockage, since net structure formed by indefinite fiber has variable and motility.
  • It has high permeation and can keep good permeation under the pressure of earthwork.
  • it has corrosion resistance, uses chemical fiber such as polypropylene or Dacronas raw material, has acid and alkali resistance, hasn’t corrosion or moth eating and has oxidation resistance
  • it has convenient construction, small weight and convenient uses.
