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 NeedTitanThermic® WeldedSeamless
Tight tolerances & dimensional consistencyOptimal — excellent control and repeatabilityGood — depends on process and batch
Cost efficiencyOptimal — lower cost with high valueModerate — higher material and energy cost
Industrial robustness & repeatabilityOptimal — higher consistency from better geometrical controlGood — process-dependent variability
SustainabilityOptimal — lower CO₂ potentialModerate — higher energy intensity
Dimensional rangeWide — comprehensive standard rangeGood — broad, but specialised above 16 mm
Geometry (eccentricity, ovality, polygonality)Optimal — excellent control for precise applicationsModerate — higher variation depending on process
Structural performance in serviceOptimal — governed by the connection design, not the individual tubeOptimal — 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.
