SCA 4 Shelf Unit Galvanised 50kg
Not the best shelving unit out there but you can't go wrong for $12.50 a piece. Pretty decent unit for what you pay for.
Load Rating: 50kg per shelf
Easy to complain about the difficulty of putting these together but I think this review sums it up well:
"Many other reviews bang on about how hard they are to assemble. Sure there are a few nuts and bolts but nothing a handy person can't take care of. I'm sure all the others saying it's a pain in the proverbial assembling them used a hand screwdriver and not a small battery operated screwdriver or battery drill with an appropriate bit. Cuts assembly time by 20 odd minutes to about 30 minutes per shelf."
