we are glad to announce, that you can have a look over our company on our new site. You can see a couple pictures about our factory, our office department and our employers. Please visit our new site "Impressions".
Placing a stainless steel flue gas system in rooms with high concentration of halogeneted hydrocarbon is inadmissible and leads to lapse of the guarantee. Halogeneted hydrocarbons which get into the combustion air of the heat generator will convert condensing flue gas into a kind of hydrochloric acid compound. This will destroy the stainless steel flue gas system. Therefore take care by operating chimney systems in: laundries, dye works, printing plants, hair salons or similar facilities.
Sheet metal fabrication
We are specialised in processing of stainless steel sheet. From individual parts and serial production to complete assemblies. From the CAD design to the complete finished product, all steps in the process were guided from our flexible skilled employees. Our machinery enables us the production of almost every possible design. Starting with laser cutting, processing at round bending machines, folding machines, longitudinal welding machines as well as various beading machines up to expanding, beading, riveting, punching, welding, all common sheet processing works are competent used from us. For the removal of machining residues at high gloss surfaces or welding seams we use a electrochemical cleaning device. We deliver different surface variations like: matt, high-gloss, ground as well as lacquered, powder coated or copper. We look forward to your request!
Pickling of stainless steel
Pickling ensures the corrosion resistance of stainless steel work pieces. Non-corrosive ("rust-free") steel is characterised by more than 10,5 percent chrome. Based on the fact by a high chrome portion, a protective and close passive layer of chromium oxide is formed at the material surface. The requirements for the forming of a error-free and effective passive layer is a pure metallic surface with a sufficiently high concentration of chrome. At heat treating processes, for example like welding, scale layers and annealing colours will be occur. Those injure the passive layer and leads to chromium poor regions. Also at mechanical processes, during storage or transporting the passive layer can be insured. Due to this the material loses his corrosion resistance. A clear sign for the loss of the corrosion resistance is the occurrence of "rust". But also against other types of corrosion like pitting corrosion, crevice corrosion and inter-crystalline corrosion the material get more vulnerable. Professionally pickled stainless steel surfaces are pure metallic. The surfaces are free of scale layers, annealing colours and external ferrite. Thus the material have his full corrosion resistance and a decorative metallic appearance.
