Multi Tier

Multi Tier

 shelving system multi tier, with an interposed mezzanine, is a construction of shelving built into two or more levels. The bottom shelving is the foundation for the mezzanine floor.

The posts are strong and dimensioned in order to carry the loads from the floor above. Shelving built as multi tier installations is often used in larger warehouses for spare parts or where the storage of many articles is required often with a low turnover.

The base of a multi-tier installation is the S90 shelving itself, built of T50 posts made of 1,0 mm pre-galvanized steel. The posts can be either pervading where the posts also carry the shelves on level two or single posts where the mezzanine once built has free standing shelving units above.

The levels are reached by staircases, elevators or conveyor systems.


The concept is based on well known shelving system S90 as a multi tier installation with interposed mezzanine floor. The design demands high sustaining-capacity of individual components resulting in an installation opening vast opportunities to plan the storing in an optimal way.

The total volume can be used for storing and handling. Low frequency articles are stored in higher located shelving positions while fast movers are located in the ground shelving.

Multi tier installations exist in many different areas and are a storage solution related to optimal warehouse utilization more than any particular branch.


A multi tier installation requires carefully specification, the total load can be considerable and because of this fact every single installation needs to be individually calculated, thus ensuring the highest possible safety.

The individual components are standard S90 parts, but due to the specific demands and possible high loads the installation is completed with stabilizing bracing, though this can depend upon the height of the installation.


Height: up to 9000 mm. Normal installation is two or three levels including the ground floor.


The warehouse building is often the limiting factor.

Loading capacity

The load capacity of the upper shelves is the same as the bottom shelves equal to 150-200 kg.

However multitier structures do need to be individually calculated and checked.
