A.b.h.t on the right side of the figure has numerical ranges respectively. On behalf of the national standard U-beam size, we will set up a special page to tell the parameters of U-beam, so that you can understand it more clearly.
General U-shaped steel is represented by H * B * A * T, for example: 120*70*60*2.5.
When calculating the theoretical weight of U-beam, we need to be clear. The bending of U-shaped steel will have a certain radian in the production process, so it will have a certain impact on the use of U-shaped steel materials. Therefore, the eight corners of the U-shaped beam are usually subtracted in the calculation, so the theoretical weight calculation formula of the U-shaped beam is as follows:
(h+2b+2a-8t)*t*7.85/ 1000
According to this formula, we will get how many kilograms per meter of U-shaped steel after angle reduction (it is worth noting that 7.85 is the density of steel! ! ! )
Conclusion: In fact, the weighing scale (theoretical weight of U-shaped steel) or the weighing of U-shaped steel is almost the same, but there are also differences. Dear friends, please choose your own calculation method when buying, in order to maximize the benefits! ! ! This is the shape of a U-beam. Let's take a look at the parameters of U-beam as follows.
