Increase Storage Density with a Rack Supported Mezzanine System

As a business grows, additional space is needed to accommodate this expansion. Unfortunately, adding on to a building or moving to a new building is often an expensive investment that can halt operations for an extended period.

One way to add space to your building while avoiding an addition is a rack supported mezzanine system, also known as a mezzanine racking system. They are a cost-effective solution that add additional capacity to a warehouse or distribution center by utilizing vertical space.

The number of levels varies from between operations. These systems can be up to 5 or 6 levels tall if there is vertical space.

Read below to learn more about rack supported mezzanine systems, including key benefits and features.

How a Rack Supported Mezzanine System Can Benefit a Distribution Center

A mezzanine racking system offers many important advantages to a distribution center’s operation, including:

High Throughput

A rack supported mezzanine system allows for multiple loading and unloading locations of pallets and/or cartons simultaneously within the system. This can be accomplished via conveyors, VRCs, and pallet drop areas, as described in the next section.

High Density

A major advantage of a rack supported mezzanine is that it provides additional vertical storage. It allows for your entire storage space to be utilized.

High Selectivity

Can be accessed by multiple employees at once. This can often eliminate ‘downtime’ during the picking process.

How to Move Items from Upper Levels to Ground Level

Something you’ll have to consider when going from a one-level system to a multi-level rack system is how you’ll move your items from the upper levels to the ground level for distribution.

There are several material handling systems that can be integrated into a rack supported mezzanine system. Each will successfully get your items to the ground level. Which one works best for you will depend on factors including your budget, your current picking process, and how drastically you’d like to change your picking process (such as if you’d like to semi-automate your operation).

Here are material handling options that work well with a rack supported mezzanine system:

Vertical Reciprocating Conveyor

VRCs are ‘elevator-like’ systems designed specifically to bring pallets or cartons of material to and from the upper levels of the mezzanine system.

Conveyor

A conveyor system can be integrated into the catwalk system to transport products to and from the upper levels of the system.

Pallet Drop Area

Pallet drops are platforms located on each level of the mezzanine system. Pallets are placed on this platform by a lift truck so that employees can load products on that level of the system from the pallet. The pallet drop typically has a safety gate to ensure employees can’t fall from the pallet drop area.

Chute

Chutes allow the picker to efficiently move any product from the upper level of the system to the floor level.

Other Components of a Mezzanine Racking System

Mezzanine racking systems can have a variety of components implemented into the system, including:

Rack Supported Mezzanine Stairs

Staircases: numerous models and options available including number of rails, angles, risers, tread, and step width.

Rack Supported Mezzanine Handrail

Handrails: integrated to keep employees safe.

Catwalk Main Aisle

Flooring: several options available resin board, corrugated decking, bar grating, open steel planking, and concrete. Each type of floor is better suited for different functions and operational features.

Rack Supported Mezzanine Gate

Gates: We can incorporate gates into your mezzanine to expedite proper material handling. Options include single swing gate, double swing gate, sliding gate, lift-out safety gate, and safety pivot gate.

Rack Supported Mezzanine Safety Netting

Safety Netting: The netting can ensure the safety of your stored materials and employees. The netting can stop your stored items from falling off the upper level to the lower level

Flue Space Keeper

Flue Keepers: Flue keepers can be attached to the uprights to maintain correct transverse flue space. The flue keepers will prevent pallets and cartons from impinging into the transverse flue space.

Rack Supported Mezzanine Kick plates

Kickplates: Can be Implemented to prevent personnel traveling on the upper levels from tripping by eliminating space along aisles and row ends. Kick plates are recommended to be installed on the upper levels of the system at all aisle row ends and along all main aisles.

Is Your Operation A Fit for A Rack Supported Mezzanine System?

There are many operations that are a good fit for a rack supported mezzanine.

As discussed, these types of systems allow you to utilize unused vertical warehouse space, thereby increasing your storage footprint in the same space. Because of this, if your operation is considering moving buildings to add storage space, this system may be a good alternative.

If you store many cartons, this type of system is typically a good fit. This type of system allows for high density and selectivity of carton storage on all levels.

The third point we’ll touch on is if you have certain types of bottlenecks in your picking process, this type of system may be right for you. For example, if pickers are often waiting on other pickers to complete a pick. This type of system will allow your pickers to be in the same aisle at the same time. Also, due to the increased space utilization you can better separate SKUs based on what items are typically picked together.
