I found some kind of bars at the BIG Coop/Konsum supermarket on Backaplan here in Gothenburgh. It is bars for the closet shelfing unit they have there. They're QUITE interesting and I have provided a link here. It might be REALLY good sturdy strong grids to use. They're about 53-55 centimeters and have different width. And by securing them with "buntband/cableties in some spots I think these could be VERy useful!
