Project

The company Wentz would like a spiral staircase with permanently welded
have a stair landing with a width of 2.45 metres protected against corrosion in one piece in the best possible way, unusual dimensions that therefore require a special dipping bath.

Realisation

For this project, the widest hot-dip galvanising bath in Germany at the ZINQ site in Maintal provided the solution: with dimensions of 8.50 x 2.60 x 3.30 metres, the oversized spiral staircase could be galvanised in a single immersion.
