Load-bearing capacity for larger shelves?
Hello,
I am setting up a shelf over a staircase in the garage, this is how it looks:


In the picture, about 320 kg is being supported.
The wall bolts are 10x120 mm wood screws with the following plug:

The plug is 12x60 mm.
After installation, I noticed a detail I missed, the mexitegel adds a few cm in depth, which means only 50 mm of the screw is in the wall, in the plug. Is this a problem?
The railing is attached with 2 bolts in the wall and is supported by several braces down to the floor, probably concrete.
The total weight will probably be around half of what is currently on it.
Should I reconsider anything, or does the construction look reasonable?

For the plug to function as intended, the screw needs to go through the bottom of it. (It's hard to say whether this is an issue or not in this specific case. In the picture, it rather seems that the sagging of the joists is the weakest link.)
Aha, hmm, then the bolts would actually need to be replaced with something longer.
In reality, nothing hangs down, the studs (70x45) hold their shape nicely
. However, I am reusing the particle board from the previous owner's construction which means a shelf entirely without the cross studs, resulting in the board becoming bent over time. In the picture, you can see it bending upwards along the sides.

Use this, vetja. Kärahjärtanes, how well it fits, I must say.
