Coil Industry

Steel and Aluminium Mills, Job-Coater

Aluminium and steel coil finishing is our focus. A strong portfolio of cleaners and pretreatment technologies are available for your coil coating and galvanizing processes. You can rely on our technical laboratory to assist you in optimizing your production processes.

In coil pretreatment we rank among the global leaders. Our specialty technologies allow for excellent corrosion protection, very good metal forming and outstanding paint adhesion. Whether aluminum, cold-rolled steel, galvanized steel or stainless steel – the metals pretreated with our products are used likewise in the automotive, building, electrical and packaging industries.

Cooperation with universities, external research institutes and plant engineering companies forms an integral part of our research and development work. This enables us to work on tomorrow’s challenges today and offer you state-of-the-art technologies that are fit for the future. Many companies which are household names have been relying on our high-performance products and technical services for many years – for a good reason: our premium surface treatment technologies allow you to simplify your process flows, enhance your quality standards and achieve greater process costs savings.


Eco-friendly, chrome-free coil pretreatment prior to coating

Coil pretreatment processes can be applied in many ways. Select the optimum process from our product portfolio to suit the substrate, the application technology and the intended use of the pretreated coil material. This includes no-rinse or dry-in-place processes as well conventional pretreatment technologies such as alkaline oxidation, chromating or zinc-phosphating. Modern systems already concentrate on eco-friendly, chrome-free product solutions. Major efforts in recent years have been focused on the development of completely metal-free innovations in order to meet future legislative requirements.


Effective galvanizing for long-term protection

Whether is it for building facades, garage doors or car bodies – top-quality and effective galvanizing is needed to protect the appearance and to provide a durable and long lasting protective coating. With our highly effective and complete product range we can support you throughout the entire process – from cleaning and galvanizing through to post-treatment by phosphating and passivating. With this in mind, you can choose from a range of environmentally-sound products.
