Durable and universal UPN profiles for structures and engineering solutions
MelnaisMetāls.LV supplies a wide range of UPN profiles, which are trusted for their durability and versatility in structural and engineering applications. Our UPN profiles, manufactured to European standards, are widely used throughout Latvia, the Baltics and Scandinavia in both commercial and industrial projects.
UPN profile assortment
We offer hot-rolled steel UPN channels in a comprehensive range of sizes, with standard lengths of L-6050mm and L-12100mm, as well as custom lengths upon request. Our UPN profiles conform to EN10025 standard and are available in steel grades including S235 and S355. The UPN profile features tapered flanges and a classic U-shape design, making it suitable for both vertical and horizontal load applications.
UPN U-Channel uses
Our UPN channels are commonly used in:
Structural frames and support beams;
- Construction of trailers, containers, and equipment bases;
- Reinforcement of walls, platforms, and walkways;
- Building renovation and modular structures;
- Industrial racks and mounting systems.
The tapered flange of the UPN profile allows for optimal stress distribution in applications where loads are applied in multiple directions. UPN channels are easy to work with—cut, drilled, and welded according to project needs.

Frequently asked questions about UPN U-channels
What is a UPN profile and where is it used?
UPN is a hot-rolled U-shaped steel profile with a tapered flange. It is used for load-bearing structures, frames, platforms, trailers, industrial equipment and various engineering solutions.
What standards apply to UPN profiles?
UPN profiles are manufactured in accordance with the EN 10025 standard, which defines the quality and mechanical properties of steel.
What steel grades are available?
Steel grades S235 and S355 are available. S355 provides higher strength and is suitable for structures with higher loads.
What lengths are available?
Standard lengths are L‑6050 mm and L‑12100 mm, but we also provide cutting to individual lengths.
Are UPN profiles suitable for welding?
Yes, UPN profiles are easy to weld and process due to their uniform material thickness and good mechanical properties.
What is the difference between UPN and other profiles (HEA, IPE)?
UPN is a U-shaped profile with a tapered flange, while HEA and IPE are H-shaped profiles designed for larger load-bearing structures. The choice depends on the load and design requirements.
Do you offer delivery and metalworking?
Yes, we provide cutting to size, surface treatment, and fast delivery throughout Latvia.
