Welded vs. Seamless: Why TitanThermic® Is the Smart Choice for Small Hollow Sections
When selecting hollow sections for construction projects, long-established perceptions can sometimes overshadow the actual requirements of the application.
Welded hot finished hollow sections are a technically robust and economically attractive solution for a wide range of structural applications, delivering the performance, consistency and reliability that modern projects demand.
Our TitanThermic® hot finished hollow sections are trusted across the construction sector, helping engineers, fabricators and contractors achieve efficient and effective structural solutions.
If you're reviewing specifications or simply interested in understanding the benefits of hot finished welded hollow sections, we'd be pleased to share our experience and expertise.
Welded vs. Seamless: A Direct Comparison
| Application Need | TitanThermic® Welded | Seamless |
|---|---|---|
| Tight tolerances & dimensional consistency | Optimal — excellent control and repeatability | Good — depends on process and batch |
| Cost efficiency | Optimal — lower cost with high value | Moderate — higher material and energy cost |
| Industrial robustness & repeatability | Optimal — higher consistency from better geometrical control | Good — process-dependent variability |
| Sustainability | Optimal — lower CO₂ potential | Moderate — higher energy intensity |
| Dimensional range | Wide — comprehensive standard range | Good — broad, but specialised above 16 mm |
| Geometry (eccentricity, ovality, polygonality) | Optimal — excellent control for precise applications | Moderate — higher variation depending on process |
| Structural performance in service | Optimal — governed by the connection design, not the individual tube | Optimal — governed by the connection design, not the individual tube |
Example dimension we produce: 120 × 80 mm
Wall thickness range: 2–12 mm, produced with tight control over eccentricity and ovality — precision built for demanding applications.
Why Partner with ArcelorMittal Europe – Tubular Products?
TitanThermic® is the largest welded tubular range in Europe, backed by inline monitoring and precision control at every production step.
A few reasons customers are making the switch:
- Lengths up to 25 m — Less waste, more flexibility for bespoke lengths
- Consistent geometry and performance — Reliable properties, batch after batch
- Choice of corners — Corner radius as low as 1.5T in some cases, depending on size (T = wall thickness)
- 100% EU, from coil to tube — A fully integrated supply chain
- XCarb® available — A genuinely sustainable, lower-CO₂ choice
- Cost-efficient — Lower total cost without compromising on value
- Future-proof — Built for modern and emerging applications
- Customer-tailored solutions — Shaped by an experienced technical team
One Value Chain, Start to Finish
Raw Material → Tube Production → Testing & Inspection → Logistics → Customer Solutions
Every step is managed in-house, giving customers full traceability and consistent quality from coil to finished tube.
Safety First
Our products are designed and manufactured to help build a safer world, because performance and reliability start with safety.
It's Time to Make the Switch
Better for you. Better for the environment. Better for the future.
