Wide Flange (WF) beams are the most widely used structural steel profile for columns and girders in buildings, warehouses, and bridges. When estimating materials, the first number everyone needs is the same: how much does a WF beam weigh per meter and per bar?
How to read WF sizes
A WF size is written as depth × flange width, for example WF 200 × 100. The full specification also lists web thickness (t1) and flange thickness (t2). Two beams with the same depth can have different weights because of different thicknesses — always check the kg/m column, not just the dimensions.
WF weight table (popular sizes)
| Size | t1 (mm) | t2 (mm) | Weight (kg/m) | Weight / 12 m (kg) |
|---|---|---|---|---|
| WF 100 × 50 | 5 | 7 | 9.3 | 112 |
| WF 150 × 75 | 5 | 7 | 14.0 | 168 |
| WF 200 × 100 | 5.5 | 8 | 20.9 | 251 |
| WF 250 × 125 | 6 | 9 | 29.0 | 348 |
| WF 300 × 150 | 6.5 | 9 | 36.7 | 440 |
| WF 350 × 175 | 7 | 11 | 49.4 | 593 |
| WF 400 × 200 | 8 | 13 | 65.4 | 785 |
| WF 450 × 200 | 9 | 14 | 74.9 | 899 |
| WF 500 × 200 | 10 | 16 | 88.2 | 1,058 |
| WF 600 × 200 | 11 | 17 | 103 | 1,236 |
The full table from WF 100 to WF 900 — including indent sizes such as WF 700 × 300, WF 800 × 300, and WF 900 × 300 — is available on our products page.
Estimating tips
- Total up the length of each profile from your drawings, then multiply by kg/m.
- Use the standard 12 m bar length (or 6 m) to work out bar counts and offcuts.
- Confirm the grade — typically SS400 / SNI BjP 400; some projects specify SN490B or A572 Gr. 50.
