Is it OK to use the channel steel to do the Overhanging Scaffold? Is there any difference between the cantilever scaffold made of I-beam and channel steel?
Channel steel, of course. The difference between the channel steel and the I-beam is that the cross section of the steel beam overlaps with the center of the shaft, while the channel steel deviates slightly from the limit; the load is the whole stability of the channel. It is of little significance in construction.
Yes, both I-beam and channel steel have specifications and models. As long as they can meet the load requirements, there is no difference between them.
Personally think that as long as the channel can withstand the weight of scaffolding on the line, but also consider the case of falling things momentum
