Mass of Steel Rods per Meter
Mass of Steel Rods per Meter
The Steel Rebar Mass per Meter table is a fundamental tool in civil engineering, especially in the design of reinforced concrete structures. It is used in the following situations:
- Sizing of reinforcement;
- Budgeting and Material Planning;
- Verification of Quantities on Site;
- Self-weight calculation;
- Quality Control.
The table below shows the mass per linear meter of steel rods, based on the density of the steel (7850 kg/m³). The values are approximate and may vary slightly depending on the manufacturer.

How to Use the Table
- Diameter Selection :
- Choose the rod diameter based on the project specifications.
- Example: For a beam with 16 mm main reinforcement, the weight per meter is 1,578 kg/m .
- Calculation of Total Mass :
- Multiply the weight per meter by the total length of the rods.
- Example: If a beam requires 10 16 mm rods, each 6 meters long, the total mass is:
Total Mass = 10 x 6.0mx 1.578 kg/m = 94.68 kg
- Verification of Quantities :
- Compare the calculated total mass with the quantities delivered to the construction site to ensure compliance with the design.
Conclusion
The table is a practical and indispensable tool for engineers and technicians, enabling efficient dimensioning of reinforcement, material management and quantity control on site. Its use must be complemented by technical standards, such as Eurocode 2 (EN 1992-1-1), to ensure the accuracy and safety of calculations.
