UB 920x420x344 reference summary
The source designation identifies a Universal Beam section. Its listed dimension string is 927x418x19.3×32, which corresponds to the section depth, flange width, web thickness, and flange thickness shown in the reference data.
- Depth: 927 mm
- Width: 418 mm
- Web thickness: 19.3 mm
- Flange thickness: 32 mm
- Root fillet radius: 19 mm
- Sectional area: 437.2 cm2
- Unit weight: 343.2 kg/m
How to read the section data
Depth describes the overall vertical size of the beam, while width describes the overall flange projection across the section. Web thickness relates to the central plate between the flanges, and flange thickness describes the thickness of the upper and lower flange plates. The root fillet is the curved transition between the web and a flange, which is important when considering detailing, clearances, and section geometry.
Sectional area is useful for material and section-property references. Unit weight expresses the listed mass per unit length and can support estimating, handling, and preliminary material takeoff work. These values should not be treated as a substitute for project-specific verification.
Standard and CAD reference
The section is referenced to EN 10365:2017, which covers dimensional and related sectional information for hot-rolled steel channels, I-beams, and H-beams. The downloadable DWG resource can help users review the profile in drafting and coordination workflows. Always compare the drawing and project model with the approved design and fabrication information before issuing documents.
Related engineering topics
This section entry is most useful alongside references for Universal Beam terminology, steel section dimensions, sectional properties, connection detailing, and CAD/DWG drafting practice. Understanding how these topics relate helps users move from a catalog dimension reference to a properly checked engineering or fabrication document.
