coatings of steel elements consist of the following layers: ground (priming)
Ground paint always plays a role of anticorrosion protection. Some parts
of an item are less corrosion resistant, e.g.
welded, flash-welded and soldered joints as well as bends need a
double layer of anticorrosion primer for protection.
Priming and superficial layers are made of enamels or decorative paints.
The priming layer guarantees adherence and the life of a coating,
whereas the superficial one decides about the final look and resistance
of an item.
colour and enamel or superficial paint must always match. This ensures
adherence and, as a result, the life and strength of a coating.
coatings of the galvanized steel items usually consist of two layers, as the
role of the anticorrosion primer already plays galvanizing.
