The UB 914x305x345 is a Universal Beam reference entry for engineers, detailers, fabricators, and CAD users working with rolled structural steel sections. This page keeps the supplied dimensional data as the local reference and adds guidance for reading the designation, understanding the listed section properties, and using the associated drawing resource.
When checking a beam schedule, connection detail, fabrication drawing, or model, compare the designation with the full dimensional description rather than relying on the abbreviated name alone. The profile’s depth, width, web, flange, fillet, area, and unit-weight information each serve a different checking or detailing purpose.

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.

Sectional Area : 439.7 cm2
Unit Weight : 345.2 kg/m
How to read the UB reference
UB identifies the Universal Beam series. The designation in the page title is the profile name used for reference, while the dimension line provides the listed overall and component dimensions. These values should be read together when selecting a section in a drawing, steel schedule, or CAD library.
Meaning of the listed properties
- Depth describes the overall vertical size of the section.
- Width describes the overall flange-to-flange breadth.
- Web thickness describes the thickness of the central web.
- Flange thickness describes the thickness of the horizontal flange material.
- Root fillet radius identifies the curved transition between the web and flange, which is important when checking clearances and detailing connections.
- Sectional area is a cross-sectional property used in engineering calculations and material takeoffs.
- Unit weight expresses the mass associated with a unit length and is useful for estimating handling, transport, and dead-load effects subject to project verification.
Standard and drawing context
The source identifies EN 10365:2017 as the referenced European standard for the dimensional and sectional description of hot-rolled structural steel sections. The standard reference helps users compare section nomenclature and profile geometry consistently, but project specifications and design requirements should still be checked before procurement or fabrication.
The downloadable DWG is useful as a drafting reference for layout, section identification, and coordination. CAD geometry should be checked against the authoritative dimensional entry before it is used for fabrication, clash detection, connection detailing, or engineering calculations.
Related engineering topics
This profile entry connects naturally with Universal Beam designations, steel section properties, rolled-section tolerances, connection detailing, steel schedules, and DWG-based drafting workflows. Those topics help explain how a section reference moves from a catalog entry into a coordinated engineering model.
Frequently asked questions
What does UB mean in UB 914x305x345?
UB means Universal Beam, a designation used for a family of hot-rolled structural steel beam sections.
Why does the listed dimension line differ from the page designation?
The title is the section designation, while the dimension line reports the supplied dimensional description for the profile. Use both identifiers together when checking drawings, schedules, or CAD data.
What is the purpose of the root fillet radius?
The root fillet radius describes the curved transition between the web and flange. It can affect fit-up, connection clearances, and the way adjacent components are detailed.
Can the DWG be used directly for fabrication?
The DWG is provided as a drafting reference. Verify its geometry against the page’s source data, project requirements, fabrication tolerances, and the responsible engineer’s instructions before fabrication.
Does the unit weight determine whether this beam is suitable for a project?
No. Unit weight is one reference property among many. Section selection requires project-specific checks, including loading, span, restraints, connections, material requirements, and applicable design rules.
