Steel sections reference
Steel Section Size Reference
Quick-reference section properties for Universal Beams (UB), Universal Columns (UC), Parallel Flange Channels (PFC), hollow sections and angles. Every value is taken from published steel section tables, with the source shown under each table.
Quick answer
Structural steel sections are named by nominal depth, width and mass. A UB 305 x 127 x 48 is a Universal Beam about 305 mm deep and 127 mm wide, weighing 48 kg per metre. The tables below list published dimensions and properties for UB, UC, PFC, SHS, RHS and angle sections. They are reference data, not a design.

Steel Section Types
Six section families cover most steelwork on a building project. Each card shows the cross-section shape and what it is normally used for.
UB
Universal Beam
Deep, narrow I-section shaped to resist bending. The usual choice for floor beams, roof beams and lintel replacements. Example: 305 x 127 x 48.
UC
Universal Column
A squarer H-section with thicker flanges, so it carries load down its length. Used as columns and posts. Example: 152 x 152 x 23.
PFC
Parallel Flange Channel
A C-shape with parallel flanges that sit flat for bolting and welding. Common for edge trimming, framing and bracing. Example: 150 x 75 x 18.
RSJ
Rolled Steel Joist
The older I-section with tapered flanges. Builders still use the name for any steel beam, but parallel flange UBs are the usual choice today. No RSJ size data is shown here.
Needs engineer sign-off
SHS / RHS
Hollow Sections
Square and rectangular closed tubes that resist twisting well. Used for posts, frames, canopies and handrails. An SHS has the same properties about both axes. Example: 100 x 100 x 5.
EA / UA
Angle
Two legs at 90 degrees, equal or unequal. Used for bracing, lintels, supports and brackets. Example: 120 x 120 x 8.
Section Size Tables
All figures are metric and nominal, shown as published. Use the filter to find a size, and scroll inside a table to see every column. The source sits under each table. Figures are for reference only and need engineer sign-off before they are relied on.

How To Read A Beam Designation
A designation such as UB 305 x 127 x 48 gives the nominal depth in millimetres, the nominal width in millimetres and the mass in kilograms per metre. The nominal figures are labels, not measurements. The 305 x 127 x 48 beam is listed at 311.0 mm deep and 125.3 mm wide.
Mass matters because steel is bought and moved by weight. Two beams with the same nominal size but different masses have different flange and web thicknesses, so they carry different loads.
To compare stiffness, look at Ix for sections of similar depth. A larger Ix means less deflection for the same load and span.
What do these columns mean?
D
Depth of the section, in millimetres.
B
Width of the section, in millimetres.
t
Web thickness. The web is the vertical plate between the flanges.
T
Flange thickness. The flanges are the top and bottom plates.
Mass
Mass per metre of length, in kilograms.
Area
Cross-sectional area, in square centimetres.
Ix
Second moment of area about the major axis x-x. Higher means stiffer in bending, so less deflection.
Iy, Iz
Second moment of area about the minor axis. It governs sideways stiffness.
Wel
Elastic section modulus. Used to check bending stress while the steel stays elastic.
Wpl
Plastic section modulus. Used when the section is allowed to reach its full plastic moment.
h x b x t
For hollow sections: overall height, overall breadth and wall thickness, in millimetres.
Cx, Cy
For angles: distance from the back of a leg to the centroid, in centimetres.
Choosing A Beam
The tables tell you which sizes exist. They do not tell you which one is right. Here is the usual order of work. For a worked example, see the steel beam we supplied for a residential extension in Speldhurst, or our structural steelwork service.
Know the span and the load
Measure the clear span between supports. Note what sits on the beam, such as a floor, a wall or a roof, and any point loads. Your engineer needs these, not a beam size.
Get the calculation
A structural engineer sizes the beam and writes the calculation. Building Control will usually ask to see it.
Check the supports
Padstones, steel-to-steel connections and the wall below need checking too. A beam that passes on paper can still fail at its bearing.
Specify the finish
Say whether the steel is primed, galvanised or painted, and whether fire protection is needed, before it is fabricated.
Reference only. A structural engineer must calculate and specify the beam before it is ordered or installed. Published tables are rounded, and manufacturers update their ranges. Check the current datasheet. Do not use this page as a design.

Steel Beam Questions
What does UB 305 x 127 x 48 mean?
It is a Universal Beam with a nominal depth of 305 mm, a nominal width of 127 mm and a mass of 48 kg per metre. In the Blue Book table the same section measures 311.0 mm deep and 125.3 mm wide, with a 9.0 mm web and 14.0 mm flanges.
What is the difference between a UB and a UC?
Both are I or H shaped. A UB is deeper than it is wide and is shaped to resist bending, so it suits beams. A UC has a squarer profile with thicker flanges, which suits columns that carry load down their length.
Compare the 305 x 127 x 48 UB (311.0 mm deep, 125.3 mm wide) with the 152 x 152 x 23 UC (152.4 mm deep, 152.2 mm wide).
What is an RSJ, and is it the same as a UB?
RSJ stands for rolled steel joist. It is the older I-section with tapered flanges, and builders still use the name for any steel beam. A UB has parallel flanges and is the usual choice today.
RSJ size data is not shown on this page: NEEDS ENGINEER SIGN-OFF.
What do Ix and Wel mean in the tables?
Ix is the second moment of area about the major axis. It describes how stiff the section is in bending, so a larger Ix means less deflection for the same load and span. Wel is the elastic section modulus, used to check bending stress. Both are in the symbols list above.
Which standards cover these sizes?
The Blue Book gives UB, UC and PFC dimensions and properties to BS EN 10365:2017, angles to BS EN 10056-1 and hollow sections to BS EN 10210-2:2006. Design is covered by Eurocode 3 (BS EN 1993-1-1) with the UK National Annex, and the SCI Blue Book (P363) collects the tables.
Can I use this page to pick a beam for my extension?
No. The tables show what sizes exist and how they are described. They do not say which size is safe for your span, load or supports. A structural engineer must calculate that, and Building Control will usually want to see the calculation.
What steel grade are beams made from?
The engineer specifies the grade on the drawings, for example S275 or S355 to BS EN 10025-2. The grade changes the strength of the steel, not the dimensions in these tables.
Can Two Js supply and fabricate beams to an engineer’s drawings?
Yes. Two Js fabricates structural steelwork and supplies builders’ beams from its workshop in East Sussex, and holds BS EN 1090 EXC3 accreditation. See Builders Beams, or send the drawings through the contact page for a quote.
