Black Steel Tubes & Profiles

Round and shape tubes for various applications

With black tubes and profiles, the entire range of welded steel tubes is available to our customers. Black steel tubes are steel in its original, natural appearance. Its characteristic surface consists of black-blue scale and burn-off that occurs during hot rolling. This coating gives black steel its name. Since the coloring of the surface cannot be influenced, every product made of black steel has an individual appearance. The technically correct describtion for black steel is "non descaled steel".

Our black steel tubes are used, for example, in the manufacture of scaffolding, truck and car trailers and light steel structures for bridge building. Our black tubes are also used in mechanical engineering, gate construction, fence construction, agricultural engineering and hall construction.

This includes absolute adherence to delivery dates - in some cases even hourly deadlines and punctual deliveries to unloading windows.

Further advantages result from the product itself.
