Our wooden shed in the back garden is filling up with items that are currently stashed on the floor. I'm planning to construct some kind of shelving to store things. Whilst none of the items are hugely heavy, I imagine that each shelf would need to bear 20-30kg. I will put in 4 or 5 shelves on/against a wall, each with a depth of at 30cm (or more, if I can).
The shed is sound. The main structure is constructed out of 2 x 1 timber studwork. It has a standard peaked roof.
I can think of three options, here listed in what I believe to be increasing order of difficulty and cost:
1) Can I use regular slot shelving (e.g. plywood) attached to the timber studwork, or are those not strong enough to support well-loaded shelves? I don't want to overload the structure of the shed and risk damaging it.
2) Or should I construct shelving out of 2 x 4 timber and screw that onto the studwork? That way I can attach to three walls in total (assuming I span the entire wall)
3) Alternatively, I will build a free standing solution, but this will require more work and more wood.
I'm concerned that I can't find any images / articles about slot shelving in wooden sheds, so perhaps (1) is cutting too many corners.
Thanks for your thoughts.
