S355 Steel Beam Supplier – UB Sizes 152×89 to 356×171, 6–12m in Stock

S355 Steel Beam Overview

Our S355 steel beam, including UB (Universal Beam) and H beam sections, is a widely used structural steel product designed for medium to heavy load-bearing applications. Manufactured in accordance with EN 10025-2 S355JR / S355J0 / S355J2, S355 provides a minimum yield strength of 355 MPa, offering an excellent balance between strength, weldability, and cost efficiency.

S355 steel beams are commonly selected for buildings, industrial plants, bridges, machinery frames, and large-scale infrastructure projects. 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 steel beams in standard European UB and H-beam profiles, with sizes range including 152x89x16 UB S355, 203×133, 254×146, 305×165, and more, supporting both stock supply and project-based orders.

Available UB S355 Steel Beam Sizes, Dimensions & Weight

Grades & Options for UB S355 Steel Beam

We supply S355 steel beams in the following sub-grades to suit different service environments:

• 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

This range allows engineers and buyers to select the appropriate S355 grade based on temperature and safety requirements.

Typical Applications of S355 Steel Beams

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 steel beam sections when they need higher strength without increasing section weight.
