The UB 203x102x23 page provides a concise reference for identifying this Universal Beam section, reviewing its listed dimensions and section data, and accessing the associated CAD file. Use the source values below when checking drawings, schedules, quantity estimates, or preliminary section comparisons.
For design work, distinguish the published geometric information from the engineering checks required for a specific application. Section selection can involve strength, stability, serviceability, connection detailing, corrosion protection, and the applicable material specification.

How to read the UB 203x102x23 designation
The designation identifies a Universal Beam profile. The source content pairs the designation with a depth of 203.2 mm, a width of 101.8 mm, a web thickness of 5.4 mm, and a flange thickness of 9.3 mm. These dimensions help engineers and detailers distinguish the section from other UB sizes and coordinate it with connected members.
Understanding the listed section data
The root fillet radius describes the curved transition between the web and flange. This region matters when considering fit-up, detailing clearances, section geometry, and how connection components relate to the rolled profile.
The listed sectional area is 29.4 cm2. The unit weight is 23.1 kg/m, which is useful for material takeoffs and handling estimates. Unit weight should not be treated as a substitute for a structural design check or as a direct statement of allowable capacity.
Reference standard and CAD workflow
This page identifies EN 10365:2017 as the referenced standard for the profile dimensions, tolerances, and sectional properties presented in the source content. Always confirm that the project specification, material documentation, and governing design basis align with the standard information used for detailing.
The downloadable DWG can support drafting and coordination workflows. Before issuing a drawing, verify the section orientation, connection clearances, end conditions, and any project-specific detailing requirements. Related SteelSTD references on section properties, steel terminology, connections and detailing, and structural steel CAD resources can provide useful context when developing the member detail.
Frequently asked questions
What type of section is UB 203x102x23?
It is a Universal Beam section. The page lists its principal dimensions, root fillet radius, sectional area, and unit weight.
What are the listed dimensions of this UB section?
The source lists a depth of 203.2 mm, width of 101.8 mm, web thickness of 5.4 mm, and flange thickness of 9.3 mm.
What does the unit weight mean?
The listed unit weight of 23.1 kg/m expresses the section’s mass per unit length. It can assist with quantity and handling estimates, but it does not establish structural capacity.
Is a DWG available for this section?
Yes. The page includes a downloadable DWG associated with the UB 203x102x23 profile. Review the file against the project drawing standard and confirm the profile orientation before use.
