Two-tiers have the shelving extending through overhead walkways to provide two levels of shelving, of a similar layout, over the same floor area. This effectively doubles storage capacity.

These free-standing storage facilities are built within the confines of the existing space. They do not affect the structure of the surrounding building, making their installation acceptable landlords.

Two tiers make full use of the available ceiling height, with greater storage capacity which helps reduce dependency on frequent deliveries and increases the work area availability. All shelving bays are accessible, 100% of the time, for ease of access and picking. Upper level can be made accessible to the reach of fork lift trucks.
