-80% zinc

Energy and resource efficiency

No sustainability without innovation, but no innovation that is not sustainable. Our branded product microZINQ® is a perfect example of this. The high-performance surface saves up to 80 % zinc compared to conventional batch galvanizing while providing the same level of corrosion protection using the thin-film process in accordance with DIN 50997. At the same time, energy is saved in the process – further increasing energy and resource efficiency. microZINQ was the first batch galvanising process to be awarded the German Raw Material Efficiency Prize by the Federal Ministry for Economic Affairs and Energy in 2013.

microZINQ was developed in our own R&D department in Germany. The goal: to develop a zinc coating that requires significantly less zinc and thus saves resources. The result was microZINQ, a binary batch galvanising process in which a zinc-aluminium alloy consisting of 95% zinc and 5% aluminium is used in a zinc melt. Thanks to the innovative thin-film process, microZINQ has on average approx. 5 – 15 µm thinner layer thicknesses compared to conventional batch galvanising. The zinc bath temperature is also reduced from around 450 degrees to 420 degrees by using a boiler for the zinc-aluminium alloy. Overall, microZINQ saves valuable resources on the product and in the process – thanks to a significant reduction in the amount of zinc used, the associated weight reduction and lower energy requirements.
