Zincaband® is an economical galvanically treated steel of the highest quality with excellent processing characteristics.

Zincaband® is available in both dull and bright surface qualities.

Fine crystalline and easily workable zinc layers in thicknesses of between 1 and 15 µm per side as required, provide the most durable protection against rust. Differential surface treatment is also possible.

Zincaband® possesses outstanding painting qualities.

Hydrogen gassing (even in high-carbon steels) is effectively prevented by the extremely high current efficiency of the sulphuric acid zinc electrolyte.
