Do you handle a wide range of warehouse goods and want to know which racking system is best for you? This post discusses the main types of racks for a warehouse and highlights their advantages and disadvantages.

A warehouse rack is an industrial shelf made of steel structures used to store your goods in an organized manner, either in boxes or on special pallets. 

Your knowledge about the types of warehouse racks is key to helping you maximize your warehouse space.

Types of Racks Used In Warehouses

You can broadly group warehouse racking systems into either pallet racking or picking racks. 

If you deal in large quantities of palletized goods, then your warehouse needs a suitable type of pallet rack, such as multi-tier racking, or long-span racking, etc.

However, if you regularly pick small quantities of items to be stored, you will find suitable rack-picking solutions such as carton flow racks.

Types of Racks: Gravity Flow Rack

The gravity flow racking system relies on the gravitational force while storing and retrieving your pallet. Its subcategories are:

gravity racking

Pallet flow racks

These are racks equipped with rollers that rely on gravity to move pallets to storage positions.

Carton Flow Racks

Carton flow racks rely on gravity and have a specific design for goods ready for picking.


  1. Provides high-density storage - optimizes warehouse storage space

  2. Allows for adjustments to fit different pallets or cartons’ dimensions

  3. Reduced labor costs

  4. Allows for easy picking of boxes

  5. Easy and less costly to design and configure


  1. It is a costly investment

  2. It requires regular maintenance for smooth operation.

Types of Racks: Single-sided and Double-sided Cantilever Rack


A cantilever racking system is a warehouse solution for storing heavy and long materials. There are single-sided or double-sided cantilever racks.


single sided cantilever rack


  1. It provides an easy way to store long and heavy non-palletized items.

  2. Maximizes vertical storage space

  3. You can adjust the rack to suit the length of your material.


  1. The rack is costly to design because of its heavy-duty structure

  2. You require an extended horizontal space for its installation

  3. It cannot accommodate your palletized goods

Types of Racks: Mezzanine Storage Rack


The Mezzanine storage rack is a racking system that is elevated from the flow to increase the storage area. Its most common options are:

Rack-Supported Mezzanine:

The support structures of the lower storage racks support this type of storage space.

Multi-tier mezzanine: 

A multi-tier mezzanine has several storage floors within your warehouse space.

Multi-Floor Mezzanine Racking


  1. It maximizes the use of vertical space

  2. Allows for easy monitoring of other warehouse operations

  3. You can customize the design to suit your specific storage needs

  4. Enhances warehouse safety and easy accessibility to stored items


  1. The initial cost is high.

  2. Requires larger horizontal space

Types of Racks: Very narrow Aisle Pallet Racking


This rack system resembles a standard rack solution. However, it is customized to occupy a smaller space. The system also has a narrow aisle. Access to pallets is through special equipment.

  1. High-density storage ensures full optimization of warehouse space

  2. You can directly access all stored pallets

  3. Reduced operation costs


  1. Access to pallets is slow 

  2. The system requires special forklifts that are expensive

  3. High initial costs

Types of Racks: Selective Pallet Racking System


The designers created selective pallet racks to facilitate the easy storage or removal of pallets or a group of tied cartons without worrying about removing other pallets. 

Key Benefits:

With a proper installation layout, here are some benefits you will get from having selective pallet racks in your warehouse.

  1. You can store or retrieve any pallet at any time because it is highly selective.

  2. It is easy to install, access, and maintain without affecting other stored products

  3.  The storage and removal of pallets require less time, making it highly efficient.

  4.  Selective pallet racks allow for easy handling of different products. 



A passage space or an aisle is required between your storage rows. Therefore, the storage density of your warehouse remains lower.

  1. To compensate for aisle space, you may require a higher floor space leading to high rental costs.

  2. You are likely to incur high labor costs because of the need to use small forklifts in several narrow warehouse aisles.

  3. When the design or installation is not properly done, it can expose warehouse workers and forklift operators to risks.

  4. For goods that require high-density storage, this will not be your best racking option, because you may need to spend on renting a warehouse with high-floor space to suit your storage needs. 

  5. If you operate a large warehouse, you will spend more on acquiring several small forklifts to store and retrieve pallets.


Types of Racks: Drive-in (LIFO) and Drive-through(FIFO) Racking

Both drive-in and drive-through racks provide high-density storage with a reduced number of aisles. 

Drive-in Warehouse Rack


Drive-in racking is a one-aisle compact racking system where the last pallet to be stored is the first to be retrieved(Last in, Fast Out)

Drive-in Warehouse Rack


  1. Compact for optimized storage capacity

  2. The warehouse optimally uses the storage space, with only one aisle remaining.

  3. Easy and quick access to pallets during storage or retrieval

  4. Enhanced safety during pallet storage and retrieval

  5. Quality control of stored products is enhanced

  6. Integration with other storage areas is easy as it allows for storing different pallets.

  7. Suitable for products with expiry dates 


  1. Suitable for only one type of product

  2. Because of its LIFO system, inventory management can be a challenge 

  3. Since a forklift operator must drive when retrieving pallets, the risk of causing damage is high.


Types of Racks: Drive-through Warehouse Racking

For a drive-through rack, the last pallet stored is the first to be retrieved or last in first out. 


  1. Optimizes storage space

  2. You can access the pallets more easily than with the drive-in system

  3. The risk of goods getting damaged during access is low

  4. Suitable for high-rotation products


  1. Require two access points which reduces the warehouse’s storage density

  2. More expensive compared to a drive-in rack solution

  3. Compared to the drive-in system, inventory control poses more challenges.

Types of Racks: Push-back Pallets Racking


This refers to a racking system in which, with the help of rollers or shuttles, you stack pallets by pushing the existing pallets from two to six pallet positions deep. 


  1. Cost-effective because it allows you to double or triple your storage space

  2. The racking system allows for both high-selective and high-density storage needs.

  3. Forklifts operate only within the aisle, limiting damage risks

  4. Maintenance costs are low

  5. You can adapt the rack to suit other racking systems


  1. It is a FILO racking system. Therefore, it is not suitable for the storage of perishable goods

  2. Some goods are not robust enough to withstand the pushing technique

  3. You can only access and remove pallets at the front of the aisle

  4. Push-back racking has a depth limit


Types of Racks: Radio Shuttle Racking System


The Rado shuttle racking system is a high-density type of warehouse racking solution with special rails for the movement of a remote-controlled shuttle vehicle. 

Types of Racks Radio Shuttle Racking System


  1. It optimizes warehouse storage space because it occupies about 80% of the warehouse space

  2. Its fast operation saves you time and makes it more efficient

  3. Operators can learn and use the racking system with ease

  4. The shuttle can operate in low and high-temperature conditions than humans

  5. It ensures the precise arrangement of pallets than other racking systems

  6. The rack design is sturdy, allowing shuttles to operate inside the rack and forklifts to operate externally. 

  7. The use of shuttles eliminated damage risks

  8. You can remotely control the shuttles. So, it keeps your labor costs low. 


  1. The initial cost is high

  2. Your operator requires training to operate and maintain the system

  3. It does not support pallets or items that require random picking
