Hot-dip galvanizing is one of the most important processes to protect steel from corrosion. Zinc is applied onto the steel strip by passing through a molten zinc bath where strip also acquires defined mechanical properties (e.g. formability, paintability, weldability).
According to the final application, Tenova provides different line configurations for zinc and several types of coatings based on zinc-aluminum alloys:
• Zinc coating for different coating thickness and paintability (cost effective material)
• Zinc-aluminum for better weldability and formability
• Aluminum-zinc (Galvalume^®) for better corrosion resistance

Thermal treatment of the strip before galvanizing pots is a key step to ensure a perfect result in galvanizing process. Tenova has the know-how to develop high performing furnaces.
For better corrosion resistance, the strip passes through a passivation section with a Chemical Coater, specifically designed by Tenova.
Tenova experience guarantees cost effective high performing lines along with total product quality.
