EN 10025 S355JR, S355J0, and S355J2 UPE Channels are widely used structural steel sections designed for demanding construction and engineering applications.
With their parallel flanges and uniform cross-section, UPE channels provide excellent load-bearing capacity, dimensional stability, and fabrication efficiency.
Manufactured in accordance with EN 10025-2, these UPE channels offer outstanding strength, durability, and weldability, making them an ideal choice for buildings, bridges, industrial structures, and heavy-duty frameworks.
A wide range of sizes, lengths, surface finishes, and end conditions is available, with customization supported to meet specific project requirements.
EN 10025 S355 UPE Channel Grades Explained
S355JR: Impact tested at +20°C, suitable for general structural use
S355J0: Impact tested at 0°C, improved toughness
S355J2: Impact tested at –20°C, ideal for low-temperature and dynamic load applications
All grades provide a minimum yield strength of 355 MPa, ensuring high structural reliability.
