Hot-dip galvanizing
Hot-dip galvanizing protects steel from corrosion in an economical and environmentally-friendly manner and considerably increases its service life. Such anti-corrosion protection lasts for decades.
How does hot-dip galvanizing work?
Hot-dip galvanizing involves dipping steel into a zinc smelter with a temperature of approx. 450° C following the appropriate pre-treatment. Zinc and steel then react with one another and an iron-zinc alloy forms on the surface of the steel. This indissoluble compound of zinc and steel creates a protection, which is very different from all other processes. Hot-dip galvanized surfaces are protected for decades not only from wind and the weather, but also from mechanical exposure. Under normal conditions, hot-dip galvanizing protects against corrosion for up to 50 years and generally for more than 25 years in the case of higher exposure.
What are the advantages of hot-dip galvanizing?
- Long-term corrosion protection,
- High level of mechanical resilience
- Perfect all-round protection in hollow parts and on edges
- Cathode corrosion protection
- Attractive appearance
- Very economical
- Maintenance free
Eco-friendly due to the use of environmentally-friendly processes.
