The blue colour ones have been introduced before. Here i want to describe single-deep pallet rack about its pros, cons, and related costs.
Single-deep pallet racking is a simple construction of metal uprights and cross-members providing immediate access to each load stored (that is, no honeycombing). Unlike block stacking, when a pallet space is created by the removal of a load, a pallet opening is immediarely available in single-deep racking. Also, because racking supports every load, stacking height is not limited by the stackability and/or crushability of the loads, and multiple SKUs can be stacked in the same vertical column of storage space.
Loads do not need to be stackable and may be of varying heights and widths. In distances where the load depth is highly variable, it may be necessary to provide load supports or decking.
