Steel coil is not something we usually come into contact with. It is commonly used in construction, car manufacturing, and machine factories. If you want to know how heavy a steel coil is, there are many tricks! The steel coil looks big and thick, but its weight is actually very particular. To calculate it clearly, you need to rely on some formulas.
1. How to calculate the weight of a steel coil
What do we rely on to calculate the weight of a steel coil? It depends on its width, thickness and material density. Generally speaking, the steel coil is a large coil, and we need to know the size and other things to measure it, otherwise the random estimate will be far off.
First, we need to know the inner diameter of the steel coil, which is the diameter of the innermost circle of the coil.
Then the outer diameter, which is the outermost diameter of the entire coil.
And the width, which is the plane width of the coil.
With these data, we can use the formula to calculate the weight. Usually it is calculated like this: weight = volume of the coil × density of the material. This density depends on the material, and the density of steel is generally around 7.85g/cm³. Simply put, the thicker and wider it is, the heavier the steel coil is.
2. The difference in weight of steel coils of different thicknesses and widths
The weight of steel coils of different thicknesses and widths is really not a number. The thicker and wider the steel coil, the heavier it will be. Some factories produce steel coils that weigh 7 to 15 tons, and some even weigh up to 30 tons. This is not a small amount!
For example, if you buy a steel coil that is 1 meter wide and 0.5 mm thick, the weight of that steel coil is much different from that of a steel coil that is 2 meters wide and 1 mm thick. If you really want to get it right, you have to use a steel coil weight calculator or something. With these tools, you don’t have to bother. Just enter the size and the machine will calculate it for you.
3. Tools and methods for calculating the weight of steel coils
Nowadays, there are many steel coil weight calculators on the Internet. Just fill in the data, such as the inner diameter, outer diameter, width, etc., and you can get a rough estimate. Don’t underestimate this tool, the calculated number is quite accurate. Especially when buying and selling steel coils, you need to have an accurate number, otherwise one ton less will be a lot of money!
- First measure the inner diameter, which is the innermost diameter of the coil.
- Then measure the outer diameter, which is the diameter of the outermost layer of the steel coil.
- Finally, measure the width. With these dimensions, the calculator can give you a rough estimate at once.
This calculation method can be used not only on steel coils, but also on copper coils, aluminum coils, etc., but the density is different, so the calculated weight is also different.
4. Common steel coil weight
Generally speaking, the weight of steel coils is set to be about the same when they leave the factory, and most of them are between 7 and 15 tons. However, for some specific needs, such as those used in construction or large machinery, some steel coils can even reach 30 tons. This weight cannot be moved casually, and special tools such as cranes and forklifts are required.
In addition, the steel coils produced by different factories may also be slightly different. Some factories make them thinner, some thicker, and the weight will be different. But no matter what, you still have to calculate by tons when buying and selling. The heavier the weight, the higher the price.
5. Use a calculator to save effort and worry
Finally, a word to those friends who need steel coils, it is easier to use a calculator to calculate the weight. We can only look at it with our naked eyes and make a rough estimate, but there is no machine to calculate it accurately. If you want steel coils for large projects, or want to buy and sell steel coils, remember to look more and compare more, and use more tools, so that the weight calculated is reliable.
In general, the weight of the steel coil is calculated based on factors such as thickness, width, inner and outer diameters. Use these data well, plus a calculator, and you can get all the data, which saves worry and effort. It doesn’t hurt for ordinary people to understand it.
