The UB 406x140x46 is a Universal Beam reference for identifying a hot-rolled structural steel section and checking its published dimensions. This page brings together the source designation, dimensional data, sectional area, unit weight, and a downloadable DWG reference.
Use the listed values as a starting point for steel selection, drafting, quantity review, and connection detailing. Final member selection and design checks should be completed against the governing project requirements, material specification, loading, restraint conditions, and applicable design rules.
UB 406x140x46
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.

Flange Thickness : 11.2 mm
Root Fillet Radius : 10 mm
Sectional Area : 58.6 cm2
Unit Weight : 46 kg/m
How to read this UB reference
The designation identifies the section within the Universal Beam range. The source content separately reports the overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. Keeping these terms distinct helps prevent confusion between the nominal product designation and the measured section dimensions.
Dimensions and section geometry
Depth and width describe the overall envelope of the section. Web thickness relates to the central vertical element, while flange thickness describes the horizontal elements. The root fillet radius records the curved transition between web and flange; this detail can matter when checking clearances, end detailing, coping, and connection interfaces.
Section properties and material takeoff
The reported sectional area is useful when reviewing section-property data and estimating steel quantities. The unit weight supports preliminary takeoff and comparison of member mass. These values should not be treated as a substitute for the complete design verification required for axial force, bending, shear, stability, deflection, or connection behavior.
Standard and CAD reference
The page identifies EN 10365:2017 as the referenced European standard for the dimensional and sectional information. For drafting workflows, the linked DWG can provide a practical geometric reference. Confirm scale, units, layer conventions, and project drafting requirements before inserting the file into production drawings.

FAQ
What is the UB 406x140x46?
It is a Universal Beam section listed with its source dimensions, sectional area, unit weight, and related geometry on this page.
Which standard is referenced for this section?
The source content refers to EN 10365:2017 for the dimensional and sectional reference.
What do the web and flange thickness values describe?
The web thickness describes the central vertical element, while the flange thickness describes the horizontal elements of the beam section.
Why is the root fillet radius included?
The root fillet identifies the curved transition between the web and flange. It can be relevant when reviewing clearances, connection details, coping, and interfaces with other components.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference. Check its units, scale, geometry, and project standards before using it in fabrication or issued construction documentation.
