The UB 356x171x57 is a Universal Beam reference entry for engineers, detailers, fabricators, and CAD users working with structural steel sections. This page brings together the listed profile dimensions, key section terminology, the cited EN 10365:2017 reference, and a downloadable DWG resource.
Use the source values below when checking drawings, comparing beam sizes, or preparing preliminary detailing. For design work, verify the required material specification, section properties, connections, and project requirements against the applicable design basis.
UB 356x171x57
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.

Width : 172.2 mm
Web Thickness : 8.1 mm
Flange Thickness : 13 mm
Root Fillet Radius : 10 mm
Sectional Area : 72.6 cm2
Unit Weight : 57 kg/m
How to read the UB 356x171x57 data
The designation identifies the Universal Beam reference, while the listed dimension line gives the measured profile description used on this page. Depth describes the overall vertical size of the section, and width describes the flange span across the profile.
Web, flange, and root geometry
The web thickness applies to the central vertical element of the beam. Flange thickness describes the horizontal elements that extend from the web. The root fillet radius identifies the curved transition between the web and flange. These details are important when reviewing clearances, connection detailing, fabrication interfaces, and CAD representations.
Sectional area and unit weight
Sectional area is a geometric property of the steel profile and is reported here in square centimetres. Unit weight expresses the listed mass per metre, making it useful for material takeoffs and handling estimates. These values should not be treated as a substitute for the complete section-property data required for structural verification.
Standard and CAD reference
The page cites EN 10365:2017 as the dimensional and sectional reference for the Universal Beam entry. The linked DWG file can support drawing coordination and detailing workflows. Before using the file in a project, check its units, layer conventions, insertion point, and compatibility with the project CAD standard.

Frequently asked questions
What does UB 356x171x57 refer to?
It is a Universal Beam reference designation. The source entry also provides the profile dimensions, sectional area, and unit weight associated with this listing.
Which standard is cited for this beam profile?
The entry refers to EN 10365:2017 for the dimensions, tolerances, and sectional properties of the relevant hot-rolled steel sections.
What do depth and width mean in the listed data?
Depth is the overall vertical dimension of the beam, while width is the overall flange direction dimension. The page separately lists web thickness, flange thickness, and root fillet radius.
Can the DWG file be used directly for structural design?
The DWG is a CAD reference resource for drawing and detailing workflows. Structural design still requires verification of the applicable material, loading, section properties, connections, and project requirements.
Why are web and flange thicknesses listed separately?
The web and flanges perform different geometric roles in the section, so their thicknesses are reported independently for dimensional checking and detailing coordination.
