Hello.
I am going to install two wall bars in a training area.
The conditions are as follows. There are three screw holes in each “side piece”; in the center and approximately 35 cm from the bottom and top. Each wall bar thus has six attachment points. The wall bar is 2.10 meters tall. The wall bar does not sit on the floor.
The wall is newly installed double drywall (standard gypsum) with metal studs.
The forces affecting the attachment points are both vertical (people standing/climbing on the wall bars) and more horizontal (elastic band training with the band in the wall bar, for example).
Would you dare to install these with M6 metal expanders? The alternative is to place plywood behind the wall bars, but I would prefer to avoid that cost.
Are there any risks I haven't described in the text that should be considered?
Thanks in advance!

I would say it won’t hold, there is a risk it will crash. Firstly, the plasterboard is not hard enough, so at the bottom there is a risk the stringer will press into the plasterboard, and the top expanders won’t be able to hold as the plasterboard will give way.
Plasterboard is never dimensioned for these forces during installation, so it could even be that the boards can come loose...
A Plywood is a good alternative, such as a pine plywood of 15-18mm.
If you think plyfa is expensive, it should be possible to place noggings between the studs just where the fastening points are. OSB is a bit cheaper than plyfa and should hold.
Some new conditions.
I can place them on the floor and the screw holes on the ones we ordered are different. From the floor, they are 2 and 8 cm from the bottom, then a hole in the middle and 2 and 8 cm from the top. Now there are suddenly 10 attachment points and support on the floor. Would you still put a board behind them?
Would you dare to hang them up without support from the floor (in metal expanders)?

No board on the wall made of wood to avoid damage to the wall and the plaster..
The plaster cannot withstand any point loads..

Metal expanders don't work. They will damage the plaster. They would have worked well just to mount the ribbed chairs, but not to use them.T TryBran said:
I have a similar project ahead of me.
It's good that it seems to be working. However, it's not certain that the plasterboards will stay in place. With your method, you have distributed the load so that it's not a point load on the board. But it's not certain that the board's attachment with screws can withstand that load. One should probably have boards behind the plaster, which are attached to the studs.
