UB 305x165x54 is a Universal Beam reference for checking the profile dimensions, mass per unit length, and related section information provided on this page. The designation identifies a specific UB profile, while the detailed entries below provide the geometry used for drafting and engineering reference.
Use this page alongside related resources on Universal Beam dimensions, steel section properties, and structural steel terminology. The downloadable DWG can also support preliminary CAD and detailing workflows, subject to project requirements and engineering review.
UB 305x165x54
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 305x165x54 reference
The source data separates the profile into its overall depth and width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. Reviewing these fields together is useful when comparing section references, checking a drawing, or confirming that a selected CAD profile matches the intended designation.
Dimensions and profile geometry
Depth and width describe the overall envelope of the section. Web and flange thicknesses describe the principal plate elements, while the root fillet radius represents the curved transition between the web and flange. That transition is part of the actual rolled profile and should not be confused with a sharp-cornered schematic shape.
Sectional area and unit weight
Sectional area is a geometric property reported in the source data. Unit weight expresses the listed mass per metre and is useful when preparing material estimates or reviewing framing information. These values should be read directly from the authoritative data on this page rather than inferred from a simplified drawing.
Standard and CAD reference
The page identifies EN 10365:2017 as the referenced European standard for the dimensions, tolerances, and sectional properties of the relevant hot-rolled steel sections. The associated DWG download provides a practical starting point for drafting; confirm units, layer conventions, connection details, and project-specific requirements before issuing drawings.
