Introduction

Surface treatment

Enclosure series CDC and SDC are made of sheet steel 1
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.

tection of steel in the ground
