Drive-In & Drive-Through Racking: Maximum Density for Bulk Storage
Maximum density for bulk storage. Store more pallets in less space when you're working with fewer SKUs.

Pallet positions than selective rack in the same footprint
Drive-in racking is a high-density warehouse storage system that eliminates aisles by allowing forklifts to drive directly into the rack structure to load and retrieve pallets. It is designed for facilities storing large quantities of the same SKU using a last-in, first-out (LIFO) inventory method. Drive-through racking is the same structure open at both ends, so pallets are loaded from one side and retrieved from the other, first in, first out (FIFO).
The Right Application
Built for Deep SKU Quantities, Not SKU Variety
Seasonal and Bulk Storage
When you're receiving and storing large quantities of a single SKU (seasonal product, raw materials, finished goods awaiting shipment), drive-in rack maximizes the number of pallet positions in your available footprint.
Cold and Freezer Storage
Refrigerated and freezer facilities pay a high cost per square foot. Drive-in rack eliminates aisles and significantly increases the pallet positions available in the conditioned footprint, reducing the cost per pallet stored.
LIFO Operations
For products where lot rotation isn't required (raw materials, bulk commodities, packaging), LIFO access is not a disadvantage. Drive-in rack trades access flexibility for density.
FIFO Lanes With Drive-Through
When pallets need to leave in the order they arrived, a drive-through layout opens the back of each lane. Pallets go in from one aisle and come out from the other, which suits staging between production and shipping and product with a date on it.
Technical Specifications
Key Specs & Configuration
| Storage Depth | 3–10+ pallets deep per lane |
| Load Capacity | 2,000–4,500 lbs typical per pallet position |
| Upright Heights | Up to 40'+ depending on facility ceiling and pallet stack |
| Inventory Method (Drive-In) | LIFO: last in, first out from the lane face |
| Inventory Method (Drive-Thru) | FIFO: load from one end, retrieve from the other |
| Lane Access | Drive-in: one entry face, often set against a wall. Drive-through: open at both ends, with an aisle on each side. |
| Best For | Bulk storage, limited SKU count, cold/freezer environments, seasonal product |
| Structural Notes | Engineered pallet rails and upright bracing, impact protection standard |
| Fire Code Notes | Dense storage triggers fire code review; in-rack sprinklers may be required depending on commodity and height |

How It Works
High Density With the Right Operational Tradeoffs
Drive-in rack replaces individual aisles with lanes that a forklift enters to place and retrieve pallets. Each lane holds one SKU; the forklift drives in to the last available position and retrieves from the front of the lane. The result is significantly more pallet positions in the same floor footprint, typically 40–60% more than selective rack in equivalent space.
The tradeoff is access flexibility. Every position in a lane is behind the positions in front of it, so SKU segregation is by lane, not by position. For operations storing large quantities of a limited number of SKUs (cold storage, seasonal distribution, beverage warehousing), that tradeoff produces real density gains without meaningful operational cost.
Drive-in systems need precise engineering. Miscalculated rail depth, inadequate bracing, or poor floor anchoring leads to structural issues. We conduct site visits, engineer for real-world forklift loads and impact forces, and handle fire code and permitting challenges, including in-rack sprinkler requirements where applicable.
Drive-through racking is the same structure with the back of each lane left open. Pallets are loaded from one aisle and retrieved from the other, so the oldest pallet in a lane is always the next one out. That FIFO rotation costs floor space: a drive-through block needs an aisle on both sides, where a drive-in block can sit against a wall, so in the same footprint drive-in holds more. Choose drive-through when rotation matters more than the last few positions, and drive-in when it does not. Our comparison of selective vs. drive-in racking covers where either one beats selective in the first place.
What You Get
Built In, Not Bolted On
Structural Steel Rails
Pallet rails run the depth of each lane, supporting pallets without beams across the aisle face. Rail height and spacing are engineered for your specific pallet profile and load weight.
Upright Protection Standard
Drive-in rack uprights take more forklift contact than selective systems. We specify column guards, end-of-aisle protectors, and base protection as standard, not as add-ons.
Stamped Drawings & Permits
Full engineering documentation, stamped drawings, and permit coordination included. Seismic compliance engineered in for your local requirements.

We Handle Design, Installation & Permitting
Hammerhead Warehouse Systems did an incredible job installing both selective pallet rack and a drive in rack system for our new distribution center! The pallet rack layout helped us maximize our storage density, streamline our picking operations and improve warehouse organization. The installation crew was hardworking, efficient, and safety focused.

Common Questions
How do you mitigate the damage risk that drive-in systems are known for?
Drive-in racking takes more forklift impact than selective systems. It's a known tradeoff of the design. We address it by specifying upright column guards, base frame protectors, and end-of-aisle impact protection as standard. We also engineer lane rail heights and depths for your specific forklift make and pallet dimensions, which reduces contact risk significantly. Regular inspections catch damage before it becomes structural.
When does drive-in make sense vs. selective racking?
Drive-in is the right answer when you have large quantities of a limited number of SKUs, LIFO rotation is acceptable, and density is more important than access flexibility. If you have many SKUs that all need direct access, selective rack is usually the better fit. We'll evaluate your product mix and storage goals before recommending anything.
Do drive-in systems require in-rack sprinklers?
It depends on your jurisdiction, building height, and commodity classification. High-density storage systems in California frequently trigger fire code review, and many installations require in-rack sprinkler protection. We coordinate with your local fire marshal during the permitting process to determine what's required, and we design around those requirements from the beginning, not after the rack is installed.
What is the difference between drive-in and drive-through racking?
Access. Drive-in racking has one entry face, so the forklift loads and retrieves from the same side and the lane runs last in, first out. Drive-through racking is open at both ends: pallets go in from one aisle and come out from the other, first in, first out. Drive-in can sit against a wall and holds more in the same footprint, while drive-through gives up an aisle to get FIFO rotation.
Is drive-through racking FIFO?
Yes, when it is run that way. Loading from one end and retrieving from the other means the first pallet into a lane is the first one out. Each lane still holds one SKU, so rotation is managed by lane. If you need FIFO with many SKUs, or need every pallet accessible, pallet flow racks or selective racking are usually the better fit.
