Your partner in corrosion protection for over 40 years!

FERTAN is a family-owned company that started production in 1979. Working from a small one-room basement apartment, founder Siegfried A. Lang worked diligently to create his first product—a formulated protective chemical barrier. Siegfried patented his rust converter and sold it from the trunk of his car.

Over four decades later, FERTAN delivers the same high-quality German designed solutions that help prevent, reduce, or eliminate corrosion. We support our international customers with their corrosion-related projects—classic car, motorcycle, home renovation, body shop, and large-scale industry—marine, freight, agriculture, and more.

Our customers have diverse needs, and FERTAN has adapted to meet those needs. Whether you require corrosion control for some metal fixings, specialized products for your classic car, or a tailor-made solution for corrosion elimination and protection specific to your industry, we are here to help.

FERTAN products also protect large metal structures like tanks, trailers, and cranes. Our innovative team of engineers continues to stay cutting-edge by bringing superior products to market. There is no limit to how far our products go. FERTAN products are found traveling the globe—supporting equipment and components used in the original manufacture of central technology systems.

Our steadfast commitment to exceeding industry standards has made us one of the largest European manufactures in anti-corrosive solutions.

Now joined by his son Bjoern Lang, Siegfried has built a company on honesty, fairness, transparency, and trust. Customer communication is still the foundation of their success. Forty years later, they always put their customer first.
