The UB 356x127x39 is a universal beam reference for checking section identification, profile dimensions, and basic steel-shape data during design and drafting work. This page brings together the listed geometry, sectional area, unit weight, applicable standard reference, and a downloadable DWG resource.
Use the reference alongside related universal beam dimensions, steel section properties, and structural steel connection detailing guidance when developing or reviewing engineering documentation.
UB 356x127x39
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 356x127x39 reference
The designation identifies a Universal Beam profile, while the dimensional entries describe the overall depth and width together with the web and flange thicknesses. These are the key profile dimensions used to recognize the section in drawings, schedules, fabrication documents, and CAD models.
Web, flanges, and root radius
The web primarily connects the two flanges and contributes to the section’s resistance to shear and other actions. The flanges provide much of the material away from the centroid, which is important when reviewing bending behavior. The root fillet is the transition between web and flange; it affects the actual rolled profile and should be considered when checking clearances, coping, connections, and detailing.
Sectional area and unit weight
Sectional area is useful for reviewing axial-force calculations, material takeoffs, and section-property references. Unit weight supports estimating line weight and steel quantities. These values should be used with the governing design basis, material specification, loading information, and complete section properties rather than treated as a standalone design check.
Standard and CAD reference
The page identifies EN 10365:2017 as the dimensional and sectional reference for the profile family. The linked DWG can support drafting and coordination, but the drawing should be checked against project requirements before it is used for fabrication or construction documentation. For further study, connect this reference with pages covering steel section naming, beam orientation, section-property notation, and CAD steel details.
Frequently asked questions
What is a UB section?
UB means Universal Beam, a rolled structural steel profile with two flanges connected by a web. The profile is commonly identified by its designation and listed dimensions.
What does the UB 356x127x39 page provide?
It provides the source-listed profile dimensions, web and flange thicknesses, root fillet radius, sectional area, unit weight, standard reference, and DWG access.
Why does the root fillet matter?
The root fillet describes the curved transition between the web and flange. It can affect fit-up, connection detailing, clearances, and the accuracy of a CAD representation.
Can the listed data alone complete a structural design?
No. Design verification also depends on the material specification, loading, restraints, connection arrangement, applicable design code, and the required section properties. A qualified engineer should confirm the section for its intended use.
