Block stacking is cost-effective and flexible, requiring no investment in pallet racking systems. It can be set up wherever there’s available floor space, adapting easily to changing storage needs. Forklifts can stack and unstack more quickly compared to selective pallet racking systems, making block stacking efficient and popular in many industries. 

However, it’s only suitable for stable and safe loads. For unstable loads, pallet racking or stacking frames are better options. Forklift operators must stack loads squarely to maintain stability.
