Steel Bar Weight Table
The purpose of a steel bar weight table is to familiarize yourself with the various weightings associated with different sizes of steel bars. This can make it easier to determine the exact weight of a bar of any given size when you need to carry out construction work or add weight to a structure.
There are a number of different factors which can affect the overall weight of a steel bar. These include the grade of steel being used, the shape of the bar and its crosssectional area. Each manufacturer may have their own specifications for the correct weight for a given size and type of steel bar and therefore its important to do the appropriate research to ascertain the exact weight in any case.
The weight of a steel bar can be calculated by multiplying the volume of the bar by the density of the steel. In this case, it is assumed that the bar is solid, rectangular and is uniform in density. The volume of a rectangular bar can be calculated by multiplying the length, width and thickness of the bar together. The density of steel is approximately 7850 kg/m3 and this number can be used in the calculation to arrive at an accurate weight.
The steel bar weight table below shows the various weightings of various sizes of rectangular steel bars. The weight is broken down into the different components such as the actual metal weight and the corresponding weight when the bar is lacquered to increase its resistance to corrosion. The weight of any bar is usually written as a weight in kilograms, e.g. 20 kg, where one kilogram is an equivalent to another thousand grams, or a kilogram (kg).
Steel Bar Weight Table
Size (in mm) Weight (kg) Lacquered (kg)
20 x 10 12.2 13.2
20 x 20 24.4 27.2
25 x 10 15.3 17.2
25 x 20 30.6 34.3
30 x 10 18.3 20.7
30 x 20 36.7 41.3
40 x 10 24.4 27.2
40 x 20 48.9 54.5
50 x 10 30.5 34.3
50 x 20 61.1 68.2
60 x 10 36.6 41.3
60 x 20 73.3 82.5
70 x 10 42.7 48.1
70 x 20 85.5 96.2
It is important to note that the actual weight of these steel bars will vary slightly due to things such as the type and grade of steel used for the manufacturing process. Also, the temperatures at which the steel bars were produced could also affect their weight. It is therefore necessary to check and compare the weight of any given steel bar with a manufacturers weight table in order to guarantee accuracy.
Using the appropriate weight table can provide useful information on the necessary specifications for a given steel bar, so that steel structures are able to hold the required weight and be constructed to the desired strength and stability. This information is essential for any buyer, contractor or designer to determine the correct weight for each application. Having an accurate understanding of weight values is also essential for any industrial or commercial business that involves machining or processing of steel, in order to ensure that their calculations are precise.
In short, the steel bar weight table provides an essential source of knowledge for anyone in the industry, from designers to engineers, who need to accurately calculate the weight of any type of steel bar in order to carry out their work. By understanding and being familiar with the weight values of different sizes of steel bars, it is possible to ensure that any project is completed safely and to the desired specifications.
