The UB 457x191x98 is a Universal Beam reference entry for engineers, detailers, fabricators, and students working with structural steel information. The source data below identifies the applicable European standard and lists the beam’s principal dimensions and section properties.
Use this page alongside related resources on Universal Beam terminology, steel section properties, and structural steel connection detailing. Before using the profile in a design or fabrication package, confirm the project’s material specification, design standard, availability, and connection requirements.

How to read the UB 457x191x98 designation
“UB” identifies a Universal Beam, while the remaining designation is the profile size and nominal unit-mass reference used for section identification. The detailed dimensional line is more useful for drafting and coordination because it separates the overall depth and width from the web and flange thicknesses.
Key profile data
The source content lists the beam’s depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values serve different purposes: dimensions support drawings and fit-up checks, sectional area is used in several analytical calculations, and unit weight supports estimating and handling considerations.
The root fillet is an important detailing feature at the transition between the web and flange. It affects how plates, fittings, weld details, and connected components are positioned. Do not assume that a flat sharp corner is available when preparing connection or fabrication details.
Using the reference in design and CAD work
- Use the listed dimensions when checking clearances, interfaces, and drawing geometry.
- Keep the section designation, standard reference, and units together in schedules and notes.
- Use the accompanying DWG resource as a drafting aid, then verify the geometry against the authoritative project or manufacturer information before fabrication.
- Do not select the beam for a structural application from size alone; design checks must also address loads, restraints, stability, connections, material specification, and the governing design rules.

Frequently asked questions
What does UB mean in UB 457x191x98?
UB means Universal Beam. It identifies the section family; the rest of the designation distinguishes this profile from other Universal Beam sizes.
What standard is referenced for this profile?
The source identifies EN 10365:2017. It is described as a European standard covering dimensions, tolerances, and sectional properties for hot-rolled steel sections.
Why are both a designation and a detailed dimension listed?
The designation provides a concise way to identify the section, while the detailed dimension line communicates the principal geometry needed for drawings, coordination, and engineering reference.
What is the root fillet radius used for?
It describes the curved transition between the web and flange. This feature should be considered when detailing plates, fittings, welds, and clearances near the section corner.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference. Check its geometry and units against the listed source data and the project’s approved information before issuing fabrication drawings.
