The UB 178x102x19 is a Universal Beam reference for checking rolled-section dimensions, terminology, and drafting information. Use the source data below when coordinating structural steel drawings, connection details, or section-property references.
This page also provides a practical way to read the listed dimensions and access the associated CAD resource. For design work, verify section selection, material, loading, stability, and connection requirements through the applicable engineering workflow.
UB 178x102x19
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.
Dimension : 177.8×101.2×4.8×7.9
Depth : 177.8 mm
Width : 101.2 mm
Web Thickness : 4.8 mm
Flange Thickness : 7.9 mm
Root Fillet Radius : 8 mm
Sectional Area : 24.3 cm2
Unit Weight : 19.1 kg/m
How to read the UB 178x102x19 reference
The listed dimension string follows the order of overall depth, flange width, web thickness, and flange thickness. These values describe the principal rolled geometry of the section. The root fillet radius identifies the curved transition between the web and flange, which is important when interpreting fabrication drawings, clearances, and detailing zones.
The sectional area and unit weight provide useful reference data for quantity takeoffs and section comparisons. They should not be treated as a complete design check: bending, shear, buckling, deflection, bearing, and connection behavior require the relevant design inputs and verification method.
Standard and drafting reference
The source identifies EN 10365:2017 as the dimensional reference for this Universal Beam designation. Consult the standard context when checking tolerances, section terminology, and compatibility with related European rolled-steel profiles. The downloadable DWG can support drafting and coordination, but drawings should be reviewed against the authoritative section data before fabrication or issue.
