Frequently asked questions

What is the Atlantis coating used in the screw anchor?

The Atlantis coating of the screw anchor is an organic coating composed of 3 layers:

  • A first layer of zinc coating, applied directly on the base material with a minimum thickness of 5 μm.
  • A second chemical conversion coating (passivating) around 1 μm thick.
  • A third layer of epoxy resin, applied as 2 sequential successive layers, with post curing, around 7 μm thickness each one.

In this way the overall total coating thickness is thicker than 20 μm.
