Galvanized Tubes & Profiles

Highest quality for tubes from our own strip galvanizing

The key to high-quality galvanized steel tubes lies in the input material and the forming process. In order to be able to guarantee the optimum input material, even with the highest zinc coatings, Wuppermann relies on its own strip galvanizing plants. The forming process has been continuously optimized based on decades of experience, so that special geometries and tightest tolerances can be produced. Our galvanized tubes and profiles are used in scaffolding, traffic engineering, solar technology, fence technology and agricultural engineering.

Wuppermann manufactures galvanized pipes and profiles based on its own hot-dip galvanized strip, which far exceed the requirements of the applicable standards. Customer-specific zinc coatings in combination with thin wall thicknesses, fabrications with very low tolerances of up to +/- 0.02 mm and the possibility of differential galvanizing are examples of the great manufacturing flexibility and a wide product diversity. Strip galvanizing has not only an economic advantage over batch galvanizing, but also a sustainable process advantage.

Your advantages with Wuppermann:

•    Individual and customer-specific zinc coatings
•    Individual profiles according to customer drawings
•    Galvanized tubes with thin wall thickness and internal galvanized weld seam
•    Differential galvanizing of tubes & profiles
•    Wall thickness tolerances up to +/- 0.02 mm
•    Free choice of weld seam position

At Wuppermann, we bring high-quality galvanized steel into the right shape. Thanks to our comprehensive state-of-the-art machinery and the know-how of our employees, we can implement almost all solutions required today and ensure the highest quality by carrying out our own tests. In addition to continuous inline pipe measurement, we also have an inline eddy current test and our own pressure test up to 150 bar.

To our standard portfolio belong:

•    Square tubes
•    Triangular tubes
•    Round tubes
•    Elliptical tubes
•    Oval tubes

In addition, we specialize in the production of individual profiles according to customer drawings in a wide range of cross-sections and wall thicknesses with the narrowest tolerances. We manufacture profiles according to individual customer drawings.
