Ever wondered how to calculate the weight of a round bar with precision? Whether you’re in construction, manufacturing, or metalworking, knowing the exact weight of your materials is crucial. This article introduces a handy round bar weight calculator, explaining its importance and how it simplifies your work. You’ll discover the formula used and how to apply it, ensuring accuracy in your projects. Dive in to streamline your material measurements and enhance your efficiency.
A round bar refers to a solid, long piece of steel that has a circular cross-section. The specifications for the round bar are expressed in millimeters and indicate its diameter. For example, a “50mm” round bar refers to a steel bar with a diameter of 50 millimeters.
The calculation formula of the round bar is:
Weight (kg/m) = Outer diameter × External diameter ×0.00617
According to the “GB/T702-2008” standard for hot-rolled steel bars, the diameter of these bars can range from 5.5mm to 310mm. The weight of the hot-rolled round steel bar can be delivered either as the actual weight or the theoretical weight.
The theoretical weight calculation formula for round steel bars is the same as that of wire rods, as both have the same shape and density. You can use the following round bar weight calculator to determine the weight of a round bar.
