UK Steel Weight Calculator — UB, UC Sections

Launch the Steel Weight Calculator →

UK Steel Mass Calculator

Calculate the total weight of UK steel sections per BS 4-1. The calculator uses standard mass per metre values from the UK section database with density 7850 kg/m³.

Supported UK Sections

• UB (Universal Beams) — 127×76 UB to 1016×305 UB, mass range 13–393 kg/m
• UC (Universal Columns) — 152×152 UC to 356×406 UC, mass range 23–634 kg/m
• UK channels — Parallel flange channels (PFC) per BS 4-1
• UK angles — Equal and unequal leg angles per BS 4-1
• Plate — Custom dimensions in mm

How to Use

1. Select the UK section type (UB, UC, channel, angle, or plate)
2. Choose the specific UK section size from the database
3. Enter the total length in metres
4. The calculator displays total mass (kg) and total weight (kN)

Worked Example

Problem: Calculate the total steel weight for 8 × 9.0 m long 533×210 UB 92 beams.

Solution:

• Mass per metre: 92 kg/m (from BS 4-1 section designation)
• Total length: 8 × 9.0 = 72.0 m
• Total mass: 72.0 × 92 = 6624 kg (6.62 tonnes)
• Total weight: 6.62 × 9.81 = 65.0 kN

Result: 6.62 tonnes of steel — use this for transport, erection, and cost estimation.

FAQ

What density does the calculator use? Standard steel density of 7850 kg/m³ (7.85 t/m³) — consistent with BS 4-1 and EN 10025.

Can I calculate plate weight? Yes. Enter plate width, length, and thickness in millimetres. The calculator converts to metres and applies the standard density.

Are UK and Australian sections the same? UK UB and UC sections are the same series as Australian UB and UC sections (both derived from British standards). However, the specific section range and mass options may differ slightly between markets. The calculator handles both correctly based on code selection.

How do UK sections compare to European IPE/HEA sections? UK UB sections have a higher depth-to-width ratio than European IPE sections. UK UC sections are closer to European HEB sections but with different flange and web thicknesses. Always select the correct regional code for accurate section data.
