Welded Steel Round Tubes

Welded steel round tubes are widely used in construction, mechanical engineering, and the manufacture of steel components. They are produced by forming a steel strip or plate into a tubular section and permanently joining the edges. Depending on the production technology, steel grade, and applicable standards, they may be intended for structural, mechanical, or piping applications.
Thanks to their wide dimensional range and the possibility of selecting wall thickness according to project requirements, welded tubes offer a practical solution for many industrial applications. When selecting a welded tube, it is important to consider not only the outside diameter and wall thickness, but also the required mechanical properties, loading conditions, and any further processing requirements.

Applications of Welded Tubes

Welded round tubes can be used in:

Structural Steelwork

Steel structures and load-bearing elements.

Machinery and Equipment

Manufacturing of machinery, equipment, and industrial systems.

Frames and Supports

Frames, supports, and structural assemblies.

Automotive and Transport

Automotive and transportation industries.

Piping and Conveying

Piping and conveying systems, provided the product is selected according to the relevant requirements.

What to Consider When Choosing?

The most important parameters include outside diameter, wall thickness, steel grade, manufacturing standard, and the required level of inspection. For welded components, weldability requirements and material properties in the welded area should also be considered.
