Hot-dip galvanizing
Steel is a fascinating material. It can however be corroded by
the elements and air contamination. Corrosion is responsible for
more than 90 billion euros worth of damage every year in Germany
alone. Hot-dip galvanizing protects steel from corrosion in an
economical and environmentally-friendly manner and considerably
increases its service life: corrosion protection lasts for
decades.
Hot-dip galvanizing involves dipping steel into a zinc smelter ca.
450° C following the appropriate pre-treatment. Zinc and steel will
then react with one another. An iron-zinc alloy will form on the
surface of the steel. This indissoluble compound of zinc and steel
creates a protection, which is clearly different from all other
processes. Hot-dip galvanized surfaces are not just protected from
wind and the weather but also optimally protected from mechanical
exposure – for decades. Under normal conditions, hot-dip
galvanizing will protect against corrosion for up to 50 years and
generally more than 25 years in the case of higher exposure
levels.
