Round Steel is less common in our lives and is mainly used for mechanical parts such as steel bars and screws used in our renovations. According to different production methods, it can be divided into cold rolling, forging and hot rolling, among which the price of hot rolling will be more expensive. So how do round bar prices count? What are the round steel brands? The following is just a brief look at it with Xiaobian.
First, how to count the price of round steel
The round bar price is calculated based on its weight, and the weight of the round bar is multiplied by the price of the day. Different types of round steel weight will be different. Some merchants will directly settle the price, we can first ask how much money a ton at the time of purchase, and then ask to pound, so that the price of round steel weight calculation formula = material density (M = 7.85) * cross-sectional area of ​​the round bar (S ) * Round bar length (H).
For example, suppose there is a round bar with a diameter of 2.2 cm round steel and a length of 6 meters. Then, the weight of this round bar = (3.14*1.12)*7.85*600=17895g, which is 17.895 kg. To put it simply, use volume* density.
