Galvanizing and powder coating (duplex)

For steel parts that need to last a long time outdoors: our partner does the hot-dip galvanizing, we apply the powder coating on top. Zinc protects against corrosion, the powder protects the zinc and provides the colour.

At a glance

Two layers, two jobs

The zinc layer protects the steel from corrosion. The powder coating on top protects the zinc from the weather and gives the part its colour. Together, both last considerably longer than either layer on its own.
