Black Tubes

With black tubes, 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".

Where are black tubes from Wuppermann used?

Our black steel tubes are used, for example, in the manufacture of scaffolding, sprinkler tubes and idler rolls 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.

What are the advantages with Wuppermann?

Wuppermann continuously delivers the highest quality through comprehensive know-how and consistent raw materials. At the same time, we offer the greatest possible flexibility thanks to our pre-material warehouse, our own slitting line and our own tube lines. This results in the highest possible delivery reliability, even with hourly deadlines and delivery slots.

Further advantages result from the product itself. We follow a zero-defect strategy and have a very high repeatability of black tubes, which is one of the special requirements for end products , such as scaffolding tubes for the construction industry. We can guarantee this repeatability due to the high degree of automation in our production.

What is part of our standard program for black tubes?

We offer high quality tubes such as round tubes, square tubes, rectangular tubes and oval tubes, made of high strength structural steels up to S460 and beyond. We always respond to the wishes of our customers, so that our products are used in the most diverse industries.
