UPN 260 is a hot-rolled steel channel with tapered flanges. This reference page brings together the section designation, nominal dimensions, geometric details, sectional area, unit weight, and a downloadable DWG resource.
Use the source data when checking drawings, comparing channel sections, or preparing a preliminary steel model. Final member selection, connection design, stability checks, and material verification should follow the applicable project requirements and engineering review.
UPN 260
Taper Flange Channels
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.

Web Thickness : 10 mm
Flange Thickness : 14 mm
Root Fillet Radius : 14 mm
Toe Radius : 7 mm
Flange Slope : 8%
Sectional Area : 48.3 cm2
Unit Weight : 37.9 kg/m
How to read the UPN 260 reference
The dimension notation identifies the channel in the order shown by the source: overall depth, flange width, web thickness, and flange thickness. Reading these items separately helps distinguish the main envelope dimensions from the thicknesses that describe the web and flanges.
Geometric features
The root fillet radius describes the curved transition between the web and a flange. The toe radius describes the rounded outer edge of the flange. These details are important when checking clearances, detailing connections, or comparing a modeled profile with a rolled-steel reference.
The flange slope indicates that the flange faces are not arranged as perfectly parallel surfaces. This taper is a defining feature of the UPN channel family and should be represented consistently in detailed CAD or section-property work.
Sectional data for design work
Sectional area is used in calculations involving the steel cross-section, while unit weight supports material takeoffs, handling estimates, and load-model preparation. These values should be read directly from the source data on this page rather than inferred from a drawing or rounded model geometry.
Standard and CAD reference
The page identifies EN 10365:2017 as the dimensional reference for the listed hot-rolled channel information. The downloadable DWG can support drafting and coordination, but users should confirm profile geometry, orientation, units, and project-specific requirements before using it in production documentation.

UPN 260 FAQ
What is a UPN 260 section?
UPN 260 is a taper flange channel designation for a hot-rolled structural steel section. The source data on this page provides its dimensions and selected section information.
How should the UPN 260 dimension string be interpreted?
The dimension string presents the overall section depth and flange width first, followed by web thickness and flange thickness. Refer to the individual source fields for the corresponding values.
What do the root and toe radii describe?
The root radius describes the curved transition from the web into a flange. The toe radius describes the rounded edge at the outer end of a flange. Both can matter when checking fit-up, clearances, and CAD geometry.
Why are sectional area and unit weight listed?
Sectional area is relevant to cross-section calculations, while unit weight is useful for estimating steel quantities and incorporating member self-weight into project workflows. Engineering calculations should use the authoritative values provided in the reference.
Can the UPN 260 DWG be used directly for fabrication?
The DWG is a drafting and modeling reference. Before fabrication or issued design documentation, verify its scale, units, profile orientation, tolerances, and consistency with the project specification and approved engineering data.
