The Buildex Bi-metal screw is used for fixing concealed fix clips to steel purlins, the product can also be used for valley fixing Side Cladding to steel purlin.

Product Advantages
Substrates
Applications
  •  Buildex® Bi-metal stainless steel screws combine the high level corrosion resistance of 300 series stainless steel and the drilling performance of carbon steel self-drilling screws
  • The only true assurance for protection against corrosive coastline, fall out and emissions from industrial stacks, chlorine and other chemically polluted environment.
  • Conform to the new Australian standards for fasteners AS3566.2. where it states screws should be inherently corrosion resistant.
  • Steel
  • General external use in mild and moderate industrial, and mild marine applications
Product Advantages
  • A mechanically deposited zinc alloy coating giving excellent galvanic protection.
  • A chromate conversion coating to passivate the zinc alloy, further inhibiting coating loss.
  • An aluminium filled polyester coating with good all-round corrosion and long-term weathering resistance
  • Minimal risk of coating damage during installation thanks to new, tougher coating formulaBetter driving performance because of a smoother, harder finish
  • Superior performance in extreme temperatures, developed and tested in Australia for Australasian conditions
  • Effective sealing of roofing sheets/cladding and reduced corrosion with an improved black non-conductive EPDM seal. The black seal remains elastic in temperature extremes, and will not breakdown and allow water entry
