It can be difficult as a Civil Engineer finding the right steel reinforcement specification whcontractors on site will be happy with and is readily available. We summarised some of the most common reinforcement and rebar sizes along with their design properties
| Reinforcement Size | Diameter (mm) | Cross-Sectional Area (mm²) | Weight per Meter (kg/m) | Yield Strength (MPa) | Tensile Strength (MPa) |
|---|---|---|---|---|---|
| 6 mm | 6 | 28.3 | 0.222 | 400 - 600 | 500 - 700 |
| 8 mm | 8 | 50.3 | 0.395 | 400 - 600 | 500 - 700 |
| 10 mm | 10 | 78.5 | 0.617 | 400 - 600 | 500 - 700 |
| 12 mm | 12 | 113.1 | 0.888 | 400 - 600 | 500 - 700 |
| 16 mm | 16 | 201.1 | 1.578 | 400 - 600 | 500 - 700 |
| 20 mm | 20 | 314.2 | 2.466 | 400 - 600 | 500 - 700 |
| 25 mm | 25 | 490.9 | 3.853 | 400 - 600 | 500 - 700 |
| 32 mm | 32 | 804.2 | 6.313 | 400 - 600 | 500 - 700 |
