A standard 10 mm steel bar typically weighs 7.41 kg.
When determining the weight of a steel bar, there are two primary measurements to consider: the total weight of a standard-length bar and its unit weight per linear meter. The weight of a "single bar" often refers to a commercially standard length, which for TMT (Thermo-Mechanically Treated) bars, is commonly 12 meters.
Weight Specifications for 10 mm Steel Bars
To provide a precise answer, we consider both common interpretations:
- Total Weight of a Standard Bar: A 10 mm diameter steel bar, sold as a single piece in its standard commercial length (often 12 meters), weighs 7.41 kg. This is the full weight of one complete bar.
- Unit Weight per Meter: For calculations requiring the weight per unit length, a 10 mm steel bar weighs 0.618 kg per meter. This value is crucial for estimating material requirements for specific lengths or projects.
Importance of Understanding Steel Bar Weights
Accurate knowledge of steel bar weights is vital for several reasons in construction and engineering:
- Logistics and Transportation: It helps in planning the transportation of materials, ensuring that vehicle weight capacities are not exceeded.
- Cost Estimation and Budgeting: Knowing the weight allows for precise calculation of material costs, which is fundamental for project budgeting.
- Structural Design and Analysis: Engineers rely on unit weights to accurately calculate the total load contributed by steel reinforcement within concrete structures, impacting design and safety.
Here is a quick reference for common steel bar sizes:
Diameter | Weight of a Single Bar (kg) | Unit Weight per Meter (kg/m) |
---|---|---|
10 mm | 7.41 | 0.618 |
12 mm | 10.67 | 0.890 |
16 mm | 18.96 | 1.59 |
20 mm | 29.63 | 2.47 |
Note: The "Weight of a Single Bar" typically corresponds to a standard length of 12 meters.
