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.

How to read the UB 533x165x85 reference
The dimensional notation identifies the beam’s overall depth and width followed by web and flange thicknesses. In the source data, these are listed as 535 x 166 x 10.3 x 16.5. The individual entries then identify the depth, width, web thickness, flange thickness, and root fillet radius separately, making the information easier to use in drawings and section schedules.
Section properties and unit weight
The listed sectional area is useful when reviewing section-property data and material takeoffs, while the stated unit weight supports preliminary mass calculations and schedule checking. These values should be kept distinct from design resistance, stiffness, buckling, and connection calculations, which require the appropriate material and design inputs.
Standard reference and CAD resource
The entry refers to EN 10365:2017, identified in the source as the reference for dimensions, tolerances, and sectional properties of hot-rolled steel channels, I-beams, and H-beams. The downloadable DWG can support drafting and coordination, but users should check the drawing against the project model, fabrication requirements, and any required connection and detailing information.
Detailing considerations
The root fillet is part of the rolled shape between the web and flange. Its presence matters when checking clearances, contact surfaces, end cuts, copes, plates, and connection components. Do not assume that a nominal flat-to-flat dimension represents every available clear space around the rolled profile.

Frequently asked questions
What is the UB 533x165x85?
It is a Universal Beam reference entry containing the source-listed dimensions, root fillet radius, sectional area, and unit weight for this steel shape.
Which standard is referenced for this section?
The source refers to EN 10365:2017 and describes it as covering dimensions, tolerances, and sectional properties for hot-rolled steel channels, I-beams, and H-beams.
What do the four values in the dimension line represent?
The dimension line lists the overall depth, overall width, web thickness, and flange thickness. The page also presents each of these values as a separate labeled entry.
Why is the root fillet radius important in detailing?
The root fillet marks the curved transition between the web and flange. It should be considered when checking fit-up, clearances, plate contact, cuts, and connection details.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference. Before fabrication, verify the profile, project tolerances, connection details, material requirements, and fabrication documentation against the responsible engineer’s or fabricator’s approved information.
