Advantages
- Exceptional Corrosion Resistance: The hot-dip galvanized coating forms a tough, metallurgical bond with the steel, providing decades of protection against rust, even in harsh environments, eliminating the need for painting and maintenance.
- High Structural Strength: The closed (square or rectangular) section offers excellent resistance to bending and torsional forces, allowing for the creation of lightweight yet rigid and reliable frames.
- Versatility and Ease of Fabrication: With precise geometry and a smooth surface, these hollow sections are easy to weld and join, making them an ideal choice for a wide range of structures—from industrial trusses to fences and loft-style furniture.
- Cost-Effectiveness: An optimal strength-to-weight ratio reduces the overall metal required for a project. The long-lasting galvanized coating significantly cuts down on maintenance costs over the structure's lifespan.
- Aesthetic Appeal: The smooth, uniform zinc coating provides a clean, finished look, allowing the sections to be used in exposed applications without needing additional decorative finishes.
Spheres of Application
- Load-bearing frames for industrial and commercial buildings (compliant with Eurocode 3: EN 1993-1-1).
- Support structures for bridges, platforms, and infrastructure projects.
- Manufacturing of heavy-duty machinery frames and conveyor systems (compliant with EN 10219).
- Building sturdy greenhouses, carports, and canopies.
- Constructing modern and durable metal fences, gates, and railings.
- Creating industrial-style furniture like loft beds, shelving units, and workbenches.
Buy Galvanized Hollow Sections from Stock
For building frames with galvanized tubes, we offer the complete package. For cladding the frame, you may need Profiled Cladding Sheets (for fences) or flat Galvanised Sheet. If the structure will be painted, the standard ERW Structural Hollow Section is a cost-effective alternative. For ready-made solutions, consider Modular mobile fence sections. UTMK provides cutting and delivery.

Can I weld galvanized hollow sections?
Yes, you can. However, it requires proper ventilation to manage zinc fumes and specific post-weld treatment of the seam (e.g., with a zinc-rich spray) to restore the anti-corrosion protection.
What is the expected lifespan of the zinc coating?
In most atmospheric conditions, a hot-dip galvanized coating can provide maintenance-free protection for over 50 years. The zinc provides both a barrier and a sacrificial (cathodic) protection to the steel underneath.
Do you offer custom lengths?
Absolutely. Our cutting services allow us to provide sections to your exact specifications, which minimizes waste on your end and saves you valuable time on-site.
What is the difference between cold-formed (EN 10219) and hot-finished (EN 10210) hollow sections?
EN 10219 sections are formed from steel strip at room temperature and then welded, making them cost-effective with tight dimensional tolerances. EN 10210 sections are formed at high temperatures, which results in different mechanical properties and makes them suitable for more demanding applications like those involving high fatigue or extreme temperatures. Our products are manufactured to the EN 10219 standard.
