Surface treatment
CDC and SDC enclosures are made of
sheet steel and are protected against
corrosion by hot-dip galvanizing
according to ISO 1461. For parts that
are buried in the ground, the corrosion
protection has been reinforced with a
polymer coating. To make sure that the
polymer coat adheres to the hot-dip
galvanized surface, it has undergone
zinc/manganese phosphating.
The above treatment gives excellent
protection against corrosion, so that
the life of the enclosures is very long
in the most commonly occurring
environments for outdoor enclosures.
