I'm planning on putting floor to ceiling shelves up in my old airing cupboard.
80cm wide, 50cm deep - secured on 3 sides to batons screwed to the 15mm plasterboard which is supported on a metal frame.
My understanding is that regular plasterboard rawplugs can take 6kg load safely, so 10 of these per shelf divided among the 3 batons SHOULD give me a safe load per shelf of 60kg.
My next concern though was total weight on the wall itself as if I had 5 of these shelves, that's 300kg total and when I read about heavy loads, it always says fix to the studs/frame.... but then I figured that since the board is screwed to the frame I only need concern myself with the strength of the individual fixings I use as the overall load of each shelf will be transmitted to the frame right?
i.e. I need to concern that each shelf is supported adequately, but if it is, the weight of that shelf is supported by the frame, NOT the board itself regardless of how it is fastened.
Is my thinking right here?
