H-beams are among the most commonly used structural steel sections in construction projects, providing excellent load-bearing capacity and design flexibility. Whether you’re building industrial frameworks, warehouses, or bridge structures, knowing the H beam dimensions, measurements, and weight per meter is essential for accurate structural design and cost estimation.

As a global steel supplier, CJM Steel provides carbon steel, galvanized, and stainless steel H-beams in a wide range of standard sizes. The tables below will help you find the right section for your project and plan material procurement efficiently.
The following H beam size chart lists standard dimensions including flange width, web thickness, and sectional height. All values are approximate and may vary slightly depending on the standard and manufacturing process.
| H Beam Size (mm) | Flange Width (mm) | Web Thickness (mm) | Section Height (mm) | Theoretical Weight (kg/m) |
| 100×100×6×8 | 100 | 6 | 100 | 17.2 |
| 150×150×7×10 | 150 | 7 | 150 | 31.1 |
| 200×200×8×12 | 200 | 8 | 200 | 49.9 |
| 250×250×9×14 | 250 | 9 | 250 | 72.4 |
| 300×300×10×15 | 300 | 10 | 300 | 94.5 |
| 350×350×12×19 | 350 | 12 | 350 | 137 |
| 400×400×13×21 | 400 | 13 | 400 | 172 |
| 500×300×11×15 | 300 | 11 | 500 | 125 |
| 600×200×12×20 | 200 | 12 | 600 | 155 |
Dimensions are based on commonly used international standards such as JIS G3101, ASTM A36, and EN 10025.
The weight of H beams depends on both section size and material density.
Below is a conversion table showing the approximate weight per meter and weight per foot for quick estimation.
| H Beam Size | Weight (kg/m) | Weight (lb/ft) |
| 100×100 | 17.2 | 11.6 |
| 150×150 | 31.1 | 20.9 |
| 200×200 | 49.9 | 33.5 |
| 250×250 | 72.4 | 48.6 |
| 300×300 | 94.5 | 63.4 |
| 350×350 | 137 | 91.9 |
| 400×400 | 172 | 115.6 |
