How many kilograms does a 50-angle bar weigh?
To calculate the weight of a 50-angle bar in kg, we need to know the material’s length, cross-sectional size, and density.
Below are the general, basic parameters:
- Length of steel
- Dimensions of the cross-section (including thickness and width)
- Density of iron material
With these parameters, the mass of a 50×50 bar can be calculated according to the following formula:
Weight (kg) = (side width x 2 - thickness) x thickness x length (m) x 7850(kg/m3)
The density of common iron is about 7850 kg/m3 (or 7.85 g/cm3).
The normal length of a 50×50 angle bar is 6 to 12 meters, from which we can calculate how many meters long a 50×50 angle bar is.
Meanwhile, the cross-sectional volume of the 50×50 angle bar depends on the specific size of each tree.
For example, for a 50×50 angle bar with a length of 6m, a thickness of 5mm, and a width of 50mm, the mass calculated by the formula will be:
Mass (kg) = (0.05×2-0.005)x0.005x6x7850 = 22.37 kg
Note that the above formula is for reference only. To calculate more accurately, we need to know the characteristics, specifications, and allowable size tolerances depending on the manufacturer.

Characteristics and specifications of the 50×50 angle bar
Angle bar 50×50 is a type of iron with a cross-sectional dimension of 50×50, manufactured from high-strength steel, and has higher hardness and durability than other types of iron.
This helps the 50×50 angle bar have better bearing capacity and is used in projects that require high durability, such as bridges, factories, high-rise buildings, etc.
Technical specifications of 50×50 angle bars are often specified according to the standards of Vietnam Steel Corporation (VNSteel) and other manufacturers.
The table below lists the basic technical specifications of the 50×50 angle bar.
| PARAMETER | VALUE |
|---|---|
| Cross-sectional size | 50mmx50mm |
| Length | 6m hoặc 12m |
| Thickness | 3mm,4mm,5mm |
| Densities | 7.850 kg/m3 |
| Hardness | 500-550 MPa |
| Tensile | 600-650 MPa |
In addition, there are some other parameters, such as bending degree, maximum bending degree, and minimum bending degree, depending on each manufacturer and applicable standard.

The difference between angle bars and other types of steel bars
In the construction industry, in addition to 50×5 angle bars, there are many other types of iron bars, such as V6, V8, and V10, each with different characteristics and specifications.
- Angle bar V6 has a cross-sectional size of 60×60 and is used in medium and large projects such as high-rise buildings, bridges, factories,
- Angle bar V8 has a cross-sectional size of 80×80 and is used in large projects such as bridges, factories, workshops,…
- Angle bar V10 has a cross-sectional size of 100×100 and is mainly used in large projects such as bridges, factories, workshops, etc.
In short, the difference between these types of iron bars lies in the cross-sectional size and technical parameters such as hardness, durability, bending, etc. Depending on the project’s requirements, we can choose a suitable type of iron.
Application
Angle bar V5 is widely used in the construction industry thanks to its outstanding features, including:
- Civil house construction: a 50×50 angle bar is used to make column frames, beams, foundations, and other construction work in civil houses.
- Construction of factories and workshops: With high durability and good bearing capacity, the 50×50 angle bar is used to build factories, workshops, warehouses,…
- Bridge construction: used to make bridge frames, giving the bridge greater durability and rigidity.
- Construction of high-rise buildings: With good bearing capacity and high stiffness, an angle bar 50×50 is used to make trusses, columns, and other construction work in high-rise buildings.
Things to note when using
To ensure the safety and effectiveness of the project, we need to note a few points when using the 50×50 angle bar:
- Check quality: Before use, check the quality to avoid technical errors cracks, or breaks.
- Proper storage: Store in a cool, dry place and avoid contact with water or chemicals.
- Ensure hardness and durability: When constructing, please comply with the requirements for the hardness and durability of the iron according to each project.
- Use lifting means properly: When transporting and installing, use lifting means properly to avoid deformation or breakage of the iron bar.
- Comply with labor safety regulations: Always comply with labor safety regulations to protect the lives and health of workers.
Table measuring the hardness and durability of the 50×50 angle bar
To better understand the hardness and durability of the 50×50 angle bar, we can refer to the hardness and durability measurement table for common types of iron as follows:
| TYPE OF STEEL | HARDNESS (MPA) | TENSILE STRENGTH (MPA) |
|---|---|---|
| V4 | 400-450 | 500-550 |
| V5 | 500-550 | 600-650 |
| V6 | 600-650 | 700-750 |
| V8 | 800-850 | 900-950 |
| V10 | 1000-1050 | 1100-1150 |
From the table above, we can see the difference in hardness and durability between types of steel. This shows that the 50×50-degree bar has quite high hardness and durability.
