Pallet stacking frames are either frames attached to standard wooden pallets or self -contained steel units made up of decks and posts. Stacking frames are portable and enable the user to stack material several loads high. When not in use, the frames can be disassembled and stored in a minimum amount of space.
Stacking frames are commonly used when loads are not stackable and when other racking alternatives are not justifiable. Also, because stacking frames can be leased, they are popular when there is a short-term spike in inventory and the frames are needed to increase storage density in what is normally open floorspace.
A single stacking frame costs between $100 and $300. The storage density losses due to honeycombing described earlier for block stacking also apply to stacking frames.
