Who we are

Seppeler Ocynkownia Śląsk plants are a part of the German Seppeler Group, whose origins go back to 1919. More than 100 years of experience in the hot-dip galvanizing industry has enabled us to develop the most effective methods of protecting steel against corrosion and to serve our customers with attention to detail.

Ocynkownia Śląsk in Poland has 4 galvanizing plants: in Chrzanów, Kluczbork, Częstochowa and Świdnica.

Traditional and modern

Bearing in mind the many years of tradition and knowledge gained during that time, we also invest in new technologies to ensure the highest possible repeatability of the set parameters and to shorten the deadlines for your orders at the same time. We also care for the environment. In this regard, we install exhaust air filters and heat recovery systems. We support you from design to just-in-time delivery.

Our commitment and motto

"Seppeler - we make it work" is not just an advertising slogan. It is more than that for us. It is a motto and a commitment as well, which has been with us for years. Besides, it is an expression of our commitment to a good and friendly relationship with our Customers. We believe that in addition to caring about the quality of our services, what also counts is our support right from the stage of your project plans right through to the completion of your investment. Experts from Ocynkownia Śląsk are willing to share their experience during dedicated training courses, and support designers and customers with their knowledge on the best preparation of structures and selection of parameters that will allow you to enjoy excellent anticorrosive protection for many years. The galvanized products can also be subjected to additional finishing, simple assembly and packaging.

As the service is provided from A to Z, i.e. from the etching of the structure to its galvanizing, we assume full guarantee responsibility, which is sometimes more difficult to obtain in the case of other types of corrosion protection.
