Scrapers and shingles are one of the special equipment in gravity separators such as APIs, DAFs and sedimentation tanks. New challenges such as design, special chemical conditions, manufacturing and operation costs, have led to the replacement of non-metallic metal materials in the construction of these equipment.


  • Much lighter
  • Corrosion-resistant

  • Up to 10 times more durable than metal
  • Energy saving of up to 80%
  • Prompt return on investment
  • Quiet when in use
  • Easy construction – easy maintenance

  • Durable and reliable


  • Slurry floor slabs
  • Surface substrates
  • Sinking tanks up to 14 meters wide and 140 meters long
  • Seed aggregates in sewage sludge
  • Chainsaws
  • APIs and DAF tanks
  • DAF sea buckthorn (completely non-metallic)
