What is High Density Racking
High density racking is one of the ideal solutions to increase your warehouse space by up to 75%. As a result, the expenses of managing your existing storage unit get reduced as these racks compactly organize a high number of SKUs. You can find high density racks in various types and sizes for your needs. Moreover, they are often grouped based on their specific features. Some of the most common subcategories of high density shelves are Drive-In, Push-Back, Flow Rack, and Pallet Shuttle.
Regardless of your choice, all high density rackings share some unified characteristics. For instance, these systems are exemplary for warehouses that deal in a high number of pallets and inventory but without excessive rotation of the SKUs. This trait makes high density racking a reasonable solution for the First In, First Out (FIFO) management system. Besides, these racks also demand the use of forklifts to handle the load.
Different Types of High Density Racking
As established earlier, high density racking includes a wide range of storage solutions. Here are the most popular and well-known racking systems, which are considered as the types of these racks.
The drive-in racks are erected from the floor to the ceiling of your warehouse. Their main components are rails and steel racks, which can be used to stockpile ten pallets deep. This type of high density racking can be utilized for limited SKUs or identical palletized products. These racks are best considered for the LIFO inventory system. Drive-in high-density racking ensures there is minimal selectivity. This leads to storing more pallets under one roof.
Pushback high density racking has a similar design to drive-in racking, making it suitable for LIFO. But you can only use two to six pallets deep. Such racking’s primary components include carts, beams, and rails. Moreover, they are built sloping at the front side of the racking system to allow pallets to travel to the pickup area using gravity instead of electric power. This type of high density racking is based on a different number of levels. Each level creates a lane and is instilled with an upward slope consisting of rolling carts.
Pallet flow is a great example of high density racking with FIFO management. One noticeable factor is that both pushback and pallet flow have a similar working mechanism as the pallets come to the front. However, you may find components like wheel beds and roller lanes attached to robust steel racks, making all the pallets move quickly toward the pickup point in this high density racking.
Pallet shuttle racks offer deep lanes for storing inventory. This type of high density racking can be completely or partially automatic. Therefore, you may not require a forklift operator to access the storage area. These racks are best for consistently loading and unloading high-volume palletized inventory.
VNA stands for Very Narrow Aisle high density racking solutions. These racks save space by storing pallet loads vertically with ease of selecting the inventory. This type of high density racking is widely used in warehouses with small aisle space. Moreover, it is a flexible storage solution where the depth and height of racking can be customized as per needs.
These are back-to-back selective racks comprised of two rows. However, this system is different in its layout design, as each pickup point gives access to the front and back pallets. Making it convenient for the forklift to reach inventory.

Perfect for small warehouses, the mobile pallet racking systems are movable on the floor since they consist of wheels. Mobile racks can be further divided into light-duty, heavy-duty, and high-bay mobile racking. Light-duty mobile racks are best for small spaces. Contrarily, heavy-duty mobile racking facilitates manufacturing, cold storage, and other gigantic warehouses. High-bay mobile racks are used for offsite storing units as they provide a vertical storage capacity of up to 35 feet.
Carton flow racks fill the space left after removing an existing pallet at the pickup spot by automatically bringing the next-in-line pallet forward. Carton flow racks are great for the FIFO inventory system. In such solutions, boxes or cartons are stored on the back so they can flow to the pickup-facing side of the system when the most recent box is already unloaded.
Features of High Density Racking




Advantages of High Density Racking
The high density pallet racking system provides multiple advantages, including:
- Improved ROI
- Fast access to SKUs
- Well organized inventory
- Maximum space optimization
- Welded carriage bases for extended durability
- Cost-effective storage system per square footage
- Compatibility with different pallet racking systems


Standard Size of High Density Racking
The size of high density racking may not be limited to any particular value. But for an idea, here are the standard sizes:
- Height: Extendable up to 30ft
- Depth: 42-inch, 48-inch, 54-inch, and 60-inch
- Width: 72-inch, 96-inch, 108-inch, and 140-inch
OKE Storage can manufacture high density racking up to 30 meters tall. We can also build racking solutions according to your warehouse area if you have customized height, width, and depth requirements.
Working Principle of High Density Racking
Unlike conventional storage systems, high density racking generally requires a single movable aisle, which saves around 50% of floor space. As a result, this racking doubles the storage capacity. Besides, when considering different types of high density solutions, mobile shelving creates more space and demands less-to-no forklift interference.
The drive in high density racking requires a forklift. The vehicle enters one end of this system and stores a pallet at the back of the rack. This process continues until the lane is filled with all the pallets and the most recently stored palled is ready to be picked up.
Conversely, the working method of high density racking, like push back, is more straightforward. The forklift operator stores a new pallet on the rack lane. Once it is loaded, the new pallet pushes the existing pallet to its back. This is one primary reason why push back racks are used in warehouses with LIFO system.
But if you see the working mechanism of a pallet flow high density racking, you will notice that the forklift loads the pallet on the lane. It automatically travels back to one side of the lane and appears at the front. Once it is picked, only then does the forklift have access to retrieve the next pallet.
On the other hand, pallet shuttle high density racking store pallets in the first available location with the help of integrated sensors. In contrast, cantilever high density racking consists of roll form or structural columns with a solid base to keep heavyweight items using a forklift.


High Density Racking Mode of Operation
When it comes to high density racking, the owners of these racks can operate it either manually or with the help of a mechanical assistant. However, it also depends on the type of aisle you have in your warehouse. Generally, high density racking permits users to access aisles regardless of time and place. But if your aisles have a PIN or swipe access system, only specific aisles will be reachable. Typically, if your shelving has controls, you can open the aisle by pressing the button. In another case, you may need to turn the handle to open the aisle. Lastly and the most common method of operating is pushing the shelves alongside the rails.
What Type of High Density Racking is Right for Your Warehouse?


As established earlier, the high density solutions are best for bulk storage, where you are required to store items in larger quantities, usually on pallets or original containers. Let’s overview the major types of high density systems suitable for your warehouse facility.
If you want to save time loading and unloading goods through the LIFO system and create unlimited storage vertically, the drive-in high density systems can be ideal for your needs. It can be a cost-effective option to maximize your current space. But, they do require forklift operators to keep and pick up the items safely.
Likewise, drive-thru systems are also a kind of high density racking, similar to drive-in. However, they need more space for installation and successful operations and are suitable for the LIFO inventory system.
Choosing push-back systems means making more space for storage with 100% inventory selectivity and enhanced capacity in your warehouse. But due to their nature, you can only use them for certain inventory. Also, they require experienced forklift operators to load and unload inventory carefully because they offer limited accessibility to the pallets.
Contrarily, you can choose pallet flow high density racking solutions due to their high storage capacity. They are best for accommodating heavy-duty perishable products. Moreover, these racks provide fast and effective rotation of inventory due to deep lane space for maximum storage. However, these racks require high maintenance and are limited to selected inventory types.
Nevertheless, if you have a big warehouse floor space and cost is not an issue, selecting pallet shuttles as your high density shelving can be an absolute option. These are even supreme storage solutions for storing high-volume cartons with ease.
Last but not least, you can opt for mobile storage high density systems if you have a limited warehouse space.

Warehousing
Best for warehouse facilities since the high density racking helps enlarge vertical space for storing products. Also, these racks save traveling time from one place to another due to well-organized inventory.

High-bay Storage
Since high bay facilities are tall, you can use high density racking and customize its height up to 30+ meters. These racks can be ideal for storing heavy and long materials, such as pipes, as well as temperature-sensitive products.

Food and Beverage
High density racking can be a smart choice for storage facilities that deal with canned food and drinks with limited expiry dates for inventory rotation through the LIFO system. Contrarily, you can also store raw food items in bulk, such as grains, wheat, and rice, for extended periods without restricting other loading and unloading activities due to the maximum availability of space.

Distribution Centers
With high density racking, your distribution center can become more profitable. As these racks magnify the storage space, you can offer a wide number of shelves to more wholesalers and factories.

Retail and Bulk Storage
If you are in a wholesaling business and your major clients are retailers, you can use high density racking as your primary storage system. As a result, you can purchase products in bulk from the factory at low cost, stock them on high density racks, and sell them to more retailers.

Narrow Aisle and Spaces
If your warehouse has a narrow aisle, these racking systems can be an optimal solution to improve your storage capacity vertically. You can install high density racking to keep inventory of cosmetics, small electric gadgets, circuit boards, jewelry, and similar items in greater quantity.

Heavy and Light-Duty Shelving
Notably, the high density racking is suitable for both light and heavyweight stocks. From pens, headphones, and towels to power drills, palletized goods, and tires, you can store all these products within this shelving system.
