Warehousing is all about making the best use of available storage space. With that, you also have to focus on keeping the space functional.
But while trying to maximise storage capacity, other factors such as affordability and accessibility might often be undermined.
In this scenario, your first step should be to analyze what type of warehouse racking system works best for your storage needs.
So in this blog, we will be talking about two high-density storage – drive-in rackings and double deep rackings. Furthermore, we’ll be understanding the comparison based on different factors. Let us dive right in:
Key Takeaways
- Drive-in rackings offer the highest storage density, similar for storing similar products in bulk.
- Double deep racks offer high storage and as well higher selectivity than drive-in racks.
- Both systems operate on Last-in-first-out (LIFO) systems.
- Drive-in racks require greater structural strength and more frequent maintenance.
- Double deep racks are more cost-effective than drive-ins due to the latter having higher upfront costs.
What is drive-in pallet racking?
Drive-in pallet racking is a storage system where stock keeping units (SKUs) are accessed through a forklift truck. The truck is driven into racking, thus it is named ‘drive-in’ racking. Since they use forklifts for access, the need for aisle space is also minimised.
The key characteristics of drive-in rackings are as follows:
High storage density: Drive-in rackings take the benefits of pallet rackings to the next level by maximising both floor and ceiling space. Relative to standard selective rackings, it increases storage capacity by up to 60-80%.
LIFO system: These rackings follow last-in-first-out inventory management system i.e. the stock that goes in last is the first to be taken out.
Protection of goods: Pallets are stored within a high structure which is surrounded by steel frames, keeping them protected from any accidental impact or damage.
What are they suitable for?
Consider the above mentioned characteristics, here are some options drive-in pallet rackings are suitable for:
- This warehouse racking system is ideal for storing large quantities of homogeneous products where selectivity is less of a priority.
- These are suited for warehouses situated in expensive areas where every metre of space matters.
What is double deep pallet racking?
Double deep pallet racking is a racking system which stores goods two pallets deep in a single rack, and can usually be accessed only from one side.
Following are some key features of this type of racking:
Higher storage density: It increases the storage density of the SKUs, these rackings provide 30%-40% more storage space from normal selective rackings.
Selectivity: Since they have increased storage space, selectivity of the inventory is compromised, making quick access difficult.
LIFO system: These rackings also operate on the last-in-first-out (LIFO) system, because pallets are stored one after another with access from only one side so the stock that goes in last is taken out first.
What are they suitable for?
The characteristics of double deep racking system make them ideal for the following situations:
- Double deep racks are suited for warehouses that need more storage space and only moderate access to the stock.
- Warehouses that store goods with long shelf lives can also use double deep pallet rackings.
Now that you understand both drive-in pallet rackings and double deep pallet rackings, now let us compare the two in the next section:
Drive-In Pallet Racking vs Double Deep Pallet Racking: A Comparison
Each storage system has its pros and cons. And the best for you depends on the circumstances. The comparison between drive-in and double deep rackings is not an absolute answer, your choice should be based on what is best for you.
Now, let us help you get an idea of what might be a good choice based on the following factors:
Costs
Double deep rackings are a more affordable option since drive-in rackings require deeper structural engineering, while the latter has moderate upfront costs. So, for high storage density on a constrained budget – double deep rackings may provide better returns.
Storage density
Both of these types provide high storage density, but double deep rackings do not match the depth and minimal aisle benefit of drive-in rackings. If you prioritise absolute maximum capacity, then drive-ins are your match. But if you might require a balance of density and accessibility, go for double deep racks.
Maintenance
Since forklifts operate in the rack bays of a drive-in system, there is a risk of collisions with the uprights. Henceforth, they might require more frequent maintenance. On the other hand, double deep racks are easier and safer to maintain.
Accessibility
Even though both the racks follow LIFO system, access to the stock is significantly easier in the double deep system since it is only stored two pallet deep. It also requires less time. So if you need access to varied stock keeping units, double deep rackings will suit your purpose more.
Conclusion
In summary, there are no one-size-fits-all racks. Each type of racking is suited for specific purposes, as is the case with double deep and drive-in rackings. Your decision should depend on a combination of factors like the type of product you are warehousing, your budget and the overall turnover of your business.
The choice of what racking you should use is a crucial one. And by making the right choice, you set the pace for the steady growth of your business. Check out our ‘what is pallet racking’ blog to develop a foundational understanding of the subject.

Frequently asked questions
- When to use double deep racking?
Double deep racking is suitable when storing large quantities of slow turnover products where slightly reduced accessibility is acceptable.
- What are the different types of pallet racking?
There are various types. Some of the common ones include selective, drive-in, double deep, push-back, and pallet flow racking systems.
- What is double deep pallet racking?
Double deep pallet racking stores pallets two positions deep, making more storage for goods within the same floor space. Gold Coast Racking offers all forms of pallet racking for your needs.
- What is the difference between drive in and drive through racking?
Drive-in systems have a single entry point, while drive-through systems allow forklift trucks to access from both ends.
