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.

Epoxy layers are applied by means of low speed spin immersion in the product, plus a post curing during 30-35 minutes at 180-200 ºC.

Atlantis coating advantages:

  • Resistance to scratches
  • Resistance to acids and alkalis
  • Reduced contact galvanic pair
  • No affected by hydrogen embrittlement
  • Due to the low process temperature, there is no change of hardness neither metallographic properties.
  • Chrome VI free
  • Reach and RoSH compliant
  • Different colours available (silver, blue, yellow, green, etc.)
  • Salt spray corrosion resistance ISO 9227 > 600 horas
  • Higher corrosion resistance than hot dip galvanized (HDG) 45 μm thick.
