The UB 254x146x43 is a Universal Beam reference for identifying a hot-rolled structural steel section in engineering, detailing, and drafting workflows. This page brings together the section designation, dimensional information, sectional area, unit weight, and the related EN 10365 reference.
Use the data below when checking a steel schedule, reviewing a connection detail, or selecting the correct section drawing. Always verify project requirements, material specification, design actions, and connection details before using any section in a structural application.
UB 254x146x43
Universal Beams
refer to : EN 10365:2017
a European standard that defines the dimensions, tolerances, and sectional properties for hot-rolled steel channels, I-beams, and H-beams used in construction and engineering. It ensures uniformity and compatibility across European structural steel products.

How to read the UB 254x146x43 designation
The designation identifies a Universal Beam section and its nominal product designation. The listed dimension string then provides the section’s overall depth, flange width, web thickness, and flange thickness. These terms are useful when comparing a steel schedule with a fabrication drawing or a CAD model.
Section dimensions and properties
The source data separates the main geometric dimensions from other reference properties. Depth and width describe the overall envelope of the section, while web and flange thickness help describe the proportions of the rolled shape. The root fillet radius identifies the curved transition between the web and flange, which is important when modeling clearances and detailing attachments.
Sectional area and unit weight are different types of information. Sectional area describes the steel area represented by a cross-section, while unit weight supports material takeoff and handling estimates. These values should be read together with the applicable design standard, material grade, load effects, stability checks, and connection design.
Using the reference in design and drafting
- Match the beam designation and dimensions against the project steel schedule.
- Allow for the root fillet when checking fit-up, plates, stiffeners, seats, and other attached components.
- Use the downloadable DWG as a drafting aid, then confirm scale, units, layer conventions, and project modeling requirements.
- For broader terminology, compare this section with related Universal Beam, I-beam, and section-properties references on SteelSTD.
Frequently asked questions
What does UB mean?
UB means Universal Beam. It is a designation used for a family of hot-rolled structural steel beam sections.
Which standard is referenced for this section?
The source content refers to EN 10365:2017 for the dimensional and sectional reference associated with this Universal Beam.
What information is provided for the UB 254x146x43?
The page provides the section dimensions, root fillet radius, sectional area, unit weight, and a CAD drawing download. The existing technical values on the page are the controlling reference data.
Can the DWG be used directly for fabrication?
The DWG is best treated as a reference and drafting resource. Confirm the drawing units, project requirements, fabrication tolerances, material specification, and approved details before issuing fabrication information.
Does the section designation alone confirm structural capacity?
No. Capacity depends on the material, span, loading, restraint, buckling conditions, design code, and connection details. A qualified engineer should verify the complete design.
