Product information
Steel round tubes – Welded structural tube black S235JRH (1.0039) according to EN 10219
These steel round tubes are welded structural hollow sections made of structural steel S235JRH (1.0039), manufactured in accordance with EN 10219 taking into account the requirements of EN 10025. The tubes are produced by forming and welding processes and feature a circular hollow cross-section with material-typical mechanical properties and uniform wall thickness distribution. Delivery condition is black (raw), corresponding to a hot-rolled surface finish.
Main features
- Material: S235JRH (1.0039) according to EN 10219, in accordance with EN 10025
- Manufacturing: Welded structural tube
- Profile shape: Round tube (hollow section)
- Surface: Black / raw (hot-rolled)
- Weldability: Suitable for common welding processes
Note: Due to the manufacturing process, the round tubes have a longitudinal weld seam, which is process-related and does not constitute a quality defect. Surface characteristics such as mill scale, minor scratches, discoloration or transport marks may occur. Saw-cut edges are unfinished and not deburred. These characteristics correspond to the standard delivery condition and do not constitute grounds for complaint within the applicable standards.
Material properties:
- good weldability
- uniform wall thickness distribution
- material-typical strength properties
- suitable for load-bearing and non-load-bearing structures
Technical specifications
- Standard: EN 10219
- Tolerances: according to EN 10219-2
- Material grade: S235JRH (1.0039)
- Surface: Black / raw
- Lengths: Standard lengths or custom cut
- Wall thicknesses: Depending on selected dimension
Dimensional, shape and weight tolerances comply with EN 10219-2. The black surface condition corresponds to the hot-rolled delivery state without additional corrosion protection. For applications requiring increased corrosion protection, subsequent surface treatment is necessary.
Applications
- Steel and metal constructions
- Mechanical and plant engineering
- Frame and load-bearing structures
- Technical substructures
Delivery is made as a welded structural tube in accordance with EN 10219. Production-related geometric deviations within permissible standard tolerances are possible.

Solides Konstruktionsrohr nach Maß
Das Stahl Rundrohr bzw. Konstruktionsrohr wurde ordentlich zugeschnitten und kam gut geschützt an. Die Wandstärke und Verarbeitung wirken zuverlässig, das Rohr lässt sich gut für stabile Konstruktionen einsetzen. Besonders positiv war für mich, dass die Länge genau wie bestellt gepasst hat. Für Metallbau und Werkstattarbeiten eine gute Wahl.
