After the incoming inspection, the components are charged by using a device, taking into account their shape and type. In the subsequent wet-chemical pre-treatment all dirt is removed, and the steel surface is activated with a flux solution for the following galvanizing process. Rounding out the hot-dip galvanizing process are a swift, steep dipping process, a short, product-dependent dipping time, the cleaning of the bath surface before starting the slow, steep pulling out process and the removal of zinc runs.

The build-up of the iron-zinc alloy layers during the hot-dip galvanizing process can be carried out at different speeds. The chemical composition of steel with respect to silicon and phosphorus is of crucial importance, as in certain concentrations these elements accelerate the iron-zinc reaction, and thick, grey zinc coats are formed. In order to achieve perfect visual results, this fact should be taken into account already in the planning phase. 

For steel components exposed to atmospheric oxygen, hot-dip galvanizing provides highly effective corrosion protection with a very long protection duration. For many applications, the protection duration and service life are the same. Zinc coats offer low-maintenance or even maintenance-free corrosion protection. When analyzing the costs of corrosion protection measures, including maintenance and repair costs during the service life of steel constructions, hot-dip galvanizing is by far the most economical corrosion protection available, both for steel constructions and many other steel products.
