Reliable S355 Carbon Steel H Beams & UB Profiles for Global Construction Projects

S355 Steel Beam Overview

Our S355 H Beam, also referred to as UB S355 steel beam, is a widely used structural steel section designed for high-strength construction applications. Manufactured to EN 10025-2 S355JR / S355J0 / S355J2 standards, this material provides a minimum yield strength of 355 MPa, making it suitable for buildings, machinery, bridges, and general structural frameworks. If you want to understand how S355 compares with S235 and S275, see our S235 / S275 / S355 Structural Steel Comparison and Properties.

We supply hot-rolled S355 H Beam (Universal Beam) in full European size ranges including 152x89x16 UB S355, 203×133, 254×146, 305×165, and more.

Grades & Options for UB S355 Steel Beam

We supply S355 H Beams in full European size ranges, including 152x89x16 UB S355 steel beam, 203×133, 254×146, and more. Available grades include:

• S355JR – standard room temperature applications
• S355J0 – impact tested at 0°C for moderate cold conditions
• S355J2 – impact tested at –20°C for heavy-duty structures

These options allow you to select the appropriate material for your specific structural project.

Applications of S355 H Beam

Our S355 steel beams are ideal for:

• Industrial buildings, workshops, and warehouses
• Multi-story residential & commercial structures
• Heavy machinery and equipment frames
• Offshore platforms and energy structures
• Bridge components, mezzanines, and structural frameworks
• Modular & prefabricated building systems

Many structural engineers choose S355 beam sections when they need higher strength without increasing section weight.
