How to calculate weight of Steel -RHL Profile Limited
As we know that in today’s era, the use of rimmed concrete is widely used for construction works. Steel or reinforcement bars are one of the most important components of concrete required to increase the compressive strength of any construction works such as roofs, columns, heavy industrial projects, bridges, dams, reservoirs etc. .
Every construction project requires an estimate of the amount of steel to be used in the projects before starting. In addition to knowing the amount of steel required for projects, it is also needed in the transportation sector to transport the steel to the construction site.
In the transport sector, steel bar formula is needed to know the average quantity of steel to be purchased and the weight of steel, with the help of which round bar, steel plates ( Can also estimate the weight and weight of steel plates, steel pipes, I beam, H beam slabs and columns.
Generally, the weight of steel is equal to the volume and density of the steel.
For example, mass = volume x density
The density of steel is about 7850 kg/cubic metre. In this regard “how to calculate the weight of steel” there are various ways to find the weight of steel
The quantity and weight of steel required can be estimated using these formulas.
In this article, we will discuss how to calculate the weight of steel bars of different diameters using the steel weight formula.
Formula is W = D²L/162
Where
W = weight of steel bar
D = diameter of steel bar in millimeters
L = length of steel bar in meters
Example (1) – Calculate the weight of a 12 mm diameter bar 60 m long
Here D = 12 mm
- L = 60 m
- We know that W = D²L/162
- W = 12²X 60/162 = 53 kg
The weight of a 60 m 12 mm bar is 53 kg.
Let’s look at another example.
Example (2)- 100 m 16 mm bar . calculate the weight of
Here, D = 16 mm.
L = 100 m.
W(weight) = 16²x 100/162 = 158 kg.
If we put 1 meter of length for each diameter of the steel bar in the formula we will get the unit weight.
6 mm∅ bar = 6²x1/162 = 0.222 kg/m
8 mm∅ bar = 8²x1/162 = 0.395 kg/m
10 mm∅ bar = 10²x1/162 = 0.617 kg/m
12 mm bar = 12²x1/162 = 0.888 kg/m
16 mm∅ bar = 16²x1/162 = 1.580 kg/m
20 mm∅ bar = 20²x1/162 = 2.469 kg/m
If we multiply the length of the rods by the unit weight, we will get the total weight of the steel rods.
For example, the total weight of a 20 mm steel bar 1000 m long is,
= 1000 x 2.469 = 2469 kg.
Using this formula we can calculate the unit weight of different steel bars.
Here I have calculated in meters but we can calculate in feet also. To calculate in feet we have to use the following formula;
W = D²L/533
where D = diameter of the rods in mm.
L = length of rods in feet.
