How are the types of I-beam and channel ABC distinguished? Tell me about it, please.
According to the steel height, waist width, waist thickness to distinguish, C type thickness, thickness is thickest, weight is heaviest
Workers, channel steel are the same, ABD, that is, the difference between the weight, A steel lightest, work a little bit worse, B steel is more focused on doing more standard, in the next C steel is also the best
As the name suggests, the shape of the I-beam looks on the side as "work", and the channel is square and has less surface.
