Steel Section Weight Calculator

Calculate mass per metre, piece weight and total tonnage for standard rolled sections or common geometric steel shapes.

Selected section—
Mass per metre0.00 kg/m
Weight per piece0.00 kg
Total weight0.00 kg
Total tonnage0.000 ton
Total length0.00 m
Section area0.00 mm²
Mass per metre0.00 kg/m
Weight per piece0.00 kg
Total weight0.00 kg
Total tonnage0.000 ton

Standard section mode uses nominal catalogue kg/m values. Geometric mode neglects corner radii and manufacturing tolerances and provides a theoretical preliminary result for custom dimensions.

Calculation method and use

Estimates total weight of standard structural-steel profiles from tabulated mass per metre, member length and quantity.

Total weight = kg/m × Length × Quantity

Example and practical interpretation

A profile weighing 20 kg/m, 6 m long, used 10 times weighs 20 × 6 × 10 = 1,200 kg or 1.20 t.

Points to check

  • Match the exact profile series and designation to the drawings.
  • Verify final kg/m values against the applicable section table or supplier data.
  • Add plates, connections and fabrication waste separately when required.

Frequently asked questions

How is profile weight calculated?

Multiply the section mass per metre by total length and quantity.

Do IPE and HEA sections weigh the same?

No. Their geometry differs, so mass per metre differs even at similar nominal depths.

How do I convert kg to tonnes?

Divide kilograms by 1,000.

IPE vs HEA vs HEB Steel Sections: Weight Comparison and Takeoff Guide

Nominal depth alone does not determine steel weight. IPE, HEA and HEB sections use different flange and web geometries, so sections carrying the same nominal size can have very different mass per metre. This guide focuses on that difference and shows how catalogue mass becomes project tonnage.

What is the difference between IPE, HEA and HEB?

SeriesGeneral geometryWeight tendencyTakeoff implication
IPENarrower-flange I sectionGenerally lighterSmall kg/m differences become significant over long runs.
HEAWide-flange H sectionUsually heavier than IPE and lighter than HEBCommon in column and framing takeoffs.
HEBWide-flange H section with heavier web/flange proportionsGenerally the heaviest of the threeTonnage can rise quickly at the same nominal depth.

This is a weight comparison, not a section-selection recommendation. Structural capacity must be verified by design.

Same nominal depth, very different weight: 200 series

IPE 200
22.4 kg/m
HEA 200
42.3 kg/m
HEB 200
61.3 kg/m
For 100 m of section: IPE 200 ≈ 2.24 t, HEA 200 ≈ 4.23 t and HEB 200 ≈ 6.13 t. The same nominal “200” label therefore does not imply comparable project weight.

Quick IPE / HEA / HEB weight reference

Nominal seriesIPE (kg/m)HEA (kg/m)HEB (kg/m)
1008.116.720.4
20022.442.361.3
30042.288.3117

These are common nominal masses used as a quick reference for standard European sections. Verify the governing standard and current manufacturer catalogue for procurement and final takeoff.

How is total section weight calculated?

Total mass = catalogue kg/m × length × quantity

Divide kilograms by 1,000 for metric tonnes. Where a cutting list contains several lengths, calculate each line separately before summing the total.

Worked takeoff example

A frame requires 24 HEA 200 members, each 6 m long. Total length = 144 m. Using 42.3 kg/m gives 144 × 42.3 = 6,091.2 kg ≈ 6.09 t. Connection plates, base plates, bolts and cutting waste are additional.

Six checks before finalising a steel takeoff

1. Section family
Do not treat IPE, HEA and HEB as interchangeable because the nominal depth is the same.
2. Catalogue mass
Confirm kg/m or lb/ft against the governing section table or manufacturer data.
3. Length and quantity
Track cutting-list lengths and stock lengths separately where needed.
4. Connection steel
Measure plates, stiffeners, base plates and similar items separately.
5. Waste
Base cutting waste on the fabrication plan rather than assuming one universal percentage.
6. Structural design
A lighter section is not automatically suitable; strength, deflection, buckling and connections require structural checks.

Frequently asked questions

Why do IPE 200, HEA 200 and HEB 200 have different weights?

The nominal number does not define the complete cross-section. Flange width, flange thickness and web thickness differ between the section families, changing area and mass per metre.

How do I calculate steel section tonnage?

Multiply catalogue mass per unit length by total length, then convert the resulting mass to tonnes or US tons as required.

Are connection plates included in profile weight?

No. Standard mass per metre represents the rolled section itself. Plates, bolts, stiffeners and other connection components require separate takeoff.

Why can theoretical geometric weight differ from catalogue weight?

Root radii, exact rolled geometry, standard tolerances and rounding can cause differences. For standard rolled sections, use the applicable catalogue mass for final takeoff.

Can an IPE be replaced with an HEA or HEB based on weight?

No. A section substitution requires structural verification of capacity, stiffness, buckling, connections and project requirements.
