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.
