  • Coloured polyester protective coating with a thickness of 45-50 um (RAL, NCS, RR), provides additional protection against corrosion. Various colours available to suit all metal sheet variants. UV stabilizers ensure colour quality over a long period of use.
  • Hardened surface of the thread (flexible core). Corrosion resistant zinc coating has a thickness of no less than 12um.
  • The full length thread design prevents twisting and allows application without a washer. Furthermore the specific shape and type of thread allow metal sheets to be connected together.
  • Self vulcanizing EPDM washer. Temperature and UV resistant. The special shape of the washer ensures proper seating of the sealing material on the outer cladding material fixture which guarantees a proper seal.

  • Reduced drilling point ensures optimal tightness and correct hole diameter in thin metal sheets.
