Steel Channel (U-Profile – UPE / UNP) – European Standard Steel Channels for Structural Support
Steel Channel (U-Profile – UPE / UNP), also known as U-channels or C-channels, are hot-rolled steel profiles with a U-shaped cross-section. Manufactured according to European standards (EN 10279 / EN 10025), these channels are widely used in construction, mechanical structures, and industrial fabrication due to their strength, stability, and versatility.
Key Characteristics of Steel Channel (U-Profile – UPE / UNP)
U-Shaped Cross-Section
UPN channels feature a profile with two parallel flanges connected by a central web, forming a “U” shape that offers strong load-bearing capacity and easy integration with other structural components.
Tapered Flanges
The flanges of UPN channels are slightly tapered, which helps improve strength and stiffness under compressive or bending loads.
European Standard Design
Produced according to EN 10279 and EN 10025, UPN channels ensure consistent quality, dimensional accuracy, and reliable mechanical properties.
High Strength and Stability
These channels are designed to resist torsion, bending, and compression, making them ideal for horizontal and vertical load applications.
Ease of Fabrication
UPN channels can be easily drilled, cut, and welded, making them suitable for a wide range of custom construction and industrial uses.
Common Applications of Steel Channel (U-Profile – UPE / UNP)
UPN steel channels are widely used in structural and industrial applications such as:
Framing Systems
Used for secondary framing in metal buildings and steel structures.
Support Beams and Purlins
Provide reliable support in roof structures, mezzanines, and platforms.
Machinery and Equipment Frames
Ideal for constructing base frames and supports for machines and equipment.
Bracing and Reinforcement
Used in conjunction with other steel profiles to increase structural rigidity.
Civil and Industrial Projects
Common in bridges, supports, rail systems, and general steel fabrication.
