The UB 305x102x28 is a Universal Beam reference entry for engineers, detailers, fabricators, and CAD users working with structural steel sections. This page brings together the source dimensions, sectional information, standard reference, and downloadable DWG resource in one place.
Use the technical data below when checking a drawing, comparing section designations, or preparing a preliminary reference for steelwork documentation. Final selection and detailing should be verified against the applicable project requirements, material specification, loading, connections, and professional engineering review.
UB 305x102x28
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 305x102x28 reference
The designation identifies the Universal Beam section covered by this entry. The listed dimensional data describes the overall depth and width of the profile, together with the web and flange thicknesses. These dimensions are useful when checking clearances, modeling the section in CAD, and coordinating steel details with adjoining components.
Section geometry and properties
The source data separates physical geometry from section properties. Depth, width, web thickness, flange thickness, and root fillet radius describe the rolled profile itself. Sectional area and unit weight provide reference information for material takeoff, analysis inputs, and drawing coordination. They should not be treated as a complete design check; factors such as steel grade, restraint, span, loading, buckling behavior, connection design, and fabrication requirements may also govern.
Standard reference
This entry refers to EN 10365:2017, which provides a standardized reference for dimensions, tolerances, and sectional properties of hot-rolled steel channels, I-beams, and H-beams. When using this page alongside other Universal Beam or structural steel section references, check the stated standard and confirm that the profile data matches the project documentation.
DWG and drafting use
The downloadable DWG file can support CAD layout, section identification, and detailing workflows. Treat the file as a reference resource and confirm units, drawing scale, profile orientation, and project-specific drafting conventions before incorporating it into issued documents. Related references for steel connections, section properties, and structural steel terminology can help provide the surrounding design and detailing context.
Frequently asked questions
What type of section is UB 305x102x28?
It is a Universal Beam section listed in the source content with its corresponding profile dimensions and section data.
Which standard is referenced for this section?
The entry refers to EN 10365:2017 for dimensions, tolerances, and sectional properties associated with hot-rolled steel channels, I-beams, and H-beams.
What do the web and flange thickness values describe?
The web thickness describes the central vertical element of the rolled profile, while the flange thickness describes the horizontal projecting elements. These dimensions are important for CAD modeling, detailing, fit-up, and section comparison.
Can this page alone be used to select a beam for a project?
No. The listed information is a reference starting point, not a complete structural design check. Beam selection should account for the project loads, span, support conditions, steel grade, stability, connections, fabrication, and applicable design requirements.
What is the DWG file used for?
The DWG is intended as a CAD reference for the profile geometry. Verify file units, orientation, scale, and project requirements before using it in construction or fabrication documentation.
