How to read the UB 406x178x60 reference
The designation identifies a Universal Beam section and its commonly used size and mass designation. The detailed dimension string provides the geometry needed to distinguish the section, while the separate depth, width, web thickness, flange thickness, and root fillet radius entries make the profile easier to interpret for drawings and schedules.
What the listed properties mean
- Depth and width: These describe the overall envelope of the beam section and are important when checking clearances, interfaces, and drawing arrangements.
- Web thickness: This describes the central vertical part of the I-shaped profile and is commonly reviewed when developing connection and detailing information.
- Flange thickness: This describes the horizontal flange material and helps identify the section geometry in fabrication and coordination documents.
- Root fillet radius: This identifies the curved transition between the web and flange. It should be considered when detailing plates, fittings, and contact surfaces near the root.
- Sectional area: This is a geometric section property used in engineering calculations and steel quantity checks.
- Unit weight: This expresses the listed mass per unit length and can support material takeoffs and handling estimates.
Using the DWG reference
The downloadable DWG can support drafting and coordination workflows. Before using the profile in fabrication or construction documentation, compare the drawing requirements with the governing project specification, connection details, material requirements, and the engineer’s verified design information.
EN 10365:2017 is identified in the source as the reference for the section dimensions, tolerances, and sectional properties. The standard reference helps provide a consistent basis for communicating rolled steel shape information, but it does not replace project-specific design checks.
Frequently asked questions
What does UB mean?
UB means Universal Beam. It is a designation used for a family of hot-rolled structural steel beam sections.
What information is provided for UB 406x178x60?
The reference lists the section dimensions, depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight, together with an EN 10365:2017 reference.
Can the DWG be used directly for structural design?
The DWG is a drafting and coordination resource. Structural design, connection detailing, fabrication, and construction use should be verified against the project requirements and by the responsible engineer.
Why are web and flange dimensions listed separately?
They describe different parts of the beam profile and help users identify the section geometry for detailing, coordination, and engineering checks.
