The UB 127x76x13 is a Universal Beam reference entry for checking the section dimensions, listed sectional area, unit weight, and associated drafting resource. The dimensional designation identifies the nominal depth, width, and mass class used for this steel section.
Use the source data below when reviewing drawings, preparing connection details, or comparing a beam callout with a steel schedule. For design work, confirm material, loading, stability, connection behavior, and code requirements separately rather than relying on the section designation alone.

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.

Unit Weight : 13 kg/m
How to read the UB 127x76x13 designation
The name UB 127x76x13 identifies a Universal Beam with the nominal dimensions and unit-weight designation shown in the reference entry. The detailed geometry is listed separately as depth, width, web thickness, flange thickness, and root fillet radius. Keeping the designation and the detailed dimensions together helps prevent errors when transferring a section from a steel schedule into a drawing or model.
Section geometry and listed properties
The source data provides the overall depth and width together with the web and flange thicknesses. These dimensions describe the basic I-shaped profile used for layout, clearance checks, end-plate detailing, and coordination with connected members. The root fillet radius is also important when checking contact, coping, plates, stiffeners, and fabrication clearances near the flange-to-web junction.
The listed sectional area and unit weight are reference properties for material takeoff and section identification. They should not be treated as a complete design check: resistance, deflection, buckling, vibration, and connection performance depend on the project conditions and the applicable design method.
Standard reference and drafting use
This entry refers to EN 10365:2017, which provides a common basis for the dimensions, tolerances, and sectional properties of specified hot-rolled structural sections. When reviewing a drawing, compare the section callout with the detailed dimensions in the local reference data and confirm that the project specification uses the same product convention.
The downloadable DWG can support CAD coordination and detailing workflows. Before issuing fabrication or construction information, check the imported geometry, units, layer conventions, and any project-specific modeling requirements. Related reference pages for Universal Beams, section properties, steel terminology, and connection detailing can provide useful context during that review.
Frequently asked questions
What is a UB 127x76x13?
It is a Universal Beam section identified by the UB 127x76x13 designation. The reference entry gives its detailed geometry, sectional area, unit weight, and standard reference.
What are the listed dimensions of this section?
The source lists a depth of 127 mm, a width of 76 mm, a web thickness of 4 mm, a flange thickness of 7.6 mm, and a root fillet radius of 8 mm.
What are the listed sectional area and unit weight?
The listed sectional area is 16.5 cm2, and the listed unit weight is 13 kg/m. These values are useful for identification and quantity review, but they do not by themselves establish structural capacity.
Which standard is referenced for the UB 127x76x13?
The entry refers to EN 10365:2017 for the dimensional and sectional-property reference used for this Universal Beam listing.
Is a DWG file available?
Yes. The page includes a download link for the UB 127x76x13 DWG file. Review the file’s units and geometry before incorporating it into project documentation.
