How to read this UB reference
The designation UB 254x102x25 identifies a Universal Beam profile and its nominal size and mass designation. The detailed dimensions in the source content provide the information needed to distinguish the rolled section from other UB entries.
Profile dimensions
Depth describes the overall vertical extent of the beam, while width describes the flange projection across the section. Web thickness applies to the central vertical plate, and flange thickness applies to the horizontal plates. The root fillet radius describes the curved transition between the web and flange, which is important when checking clearances, detailing connections, or preparing accurate CAD geometry.
Section properties and unit weight
The listed sectional area represents the steel area through a cross-section of the member. The listed unit weight expresses the member mass per unit length and can support material takeoffs and preliminary steel quantity checks. These values should be kept separate from project-specific resistance, stability, deflection, connection, and fire design checks.
Using the DWG reference
The downloadable DWG can support drafting, coordination, and the creation of section libraries. Confirm the drawing units, insertion point, layer conventions, and project modeling requirements before incorporating it into production documentation. For related resources, see the site’s CAD/DWG references, steel shape terminology, and connection detailing topics.
UB 254x102x25 FAQ
What type of section is UB 254x102x25?
It is a Universal Beam section. The page provides its profile dimensions, sectional area, unit weight, and a DWG reference for drafting use.
What do the dimensions describe?
The listed dimensions identify the beam depth, width, web thickness, flange thickness, and root fillet radius. Together, they describe the principal geometry of the rolled profile.
Why is the root fillet radius important?
The root fillet is the rounded transition between the web and flange. It can affect fit-up, connection detailing, clearances, and the accuracy of a CAD representation.
Can the unit weight be used for a material takeoff?
Yes, the listed unit weight can support a material quantity estimate when combined with the member length. Confirm the result against the project schedule and the applicable procurement information.
Does this page provide complete structural design resistance?
No. The dimensional reference does not replace engineering checks for strength, stability, deflection, connections, fabrication, or the requirements of the governing project specification.
Which standard is referenced for this section?
The source content refers to EN 10365:2017. Use the project requirements and the applicable edition or product documentation when confirming procurement and design information.
