Drive-In / Drive-Thru Rack
Imagine walking into your warehouse on Monday morning and finding that pallets are once again stacked in the aisles. Overwhelmingly, your team is playing warehouse Tetris to fit new inventory. And if the surprise isn’t enough, your boss is asking how you can squeeze 20% more storage out of the same space without breaking the budget.
As SRS-i, we’ve been there with hundreds of warehouse managers who face this exact challenge. The math is brutal—inventory demands never stop growing, commercial rent keeps climbing, but your building stays the same size. And worse, those wide aisles are eating up vast floor space, and bottlenecks slow everything down.
That’s where SRS-i’s drive-in racking and drive-thru racking come to the rescue.
Both systems are storage density champions, but they work differently depending on how your inventory flows through your operation.
Drive-in racking allows forklift access from one side only, creating a Last-In, First-Out (LIFO) storage system. It’s ideal for large quantities of the same SKU, where you don’t need to worry about rotation. Think raw materials that don’t expire, bulk goods that sit for months, and seasonal merchandise that moves in waves.
Drive-thru racking allows access from both ends. It enables First-In, First-Out (FIFO) inventory flow. This is your go-to for date-sensitive products that absolutely must be rotated properly—food products, beverages, pharmaceuticals, and anything where expiration dates can turn into expensive disasters.
| Feature | Drive-In Racking | Drive-Thru Racking |
| Forklift Access | One-sided entry | Two-sided entry |
| Inventory Method | LIFO (Last-In, First-Out) | FIFO (First-In, First-Out) |
| Best For | Bulk, low-rotation inventory | Perishables and high-rotation stock |
| Aisle Requirements | Minimal aisles, maximum density | Slightly more access space is required |
Our high-density storage systems deliver benefits that’ll make your accountant do a happy dance:
Boost storage density by up to 75% compared to traditional selective racking—we’re talking about dramatically more inventory capacity in the same footprint. Deep storage lanes and minimal aisle requirements mean you can store significantly more pallets without the expense and headache of facility expansion.
This space efficiency is crucial in cold storage facilities where every BTU costs money, or high-rent markets where every square foot feels like it’s made of gold.
Fewer aisles translate directly to spending less money on lighting, heating, cooling, and cleaning per pallet stored. Your utility bills will thank you. And so will your budget.
Shorter forklift travel distances mean lower fuel consumption, reduced battery usage, and faster pick speeds. That boosts overall productivity. The Warehouse Education and Research Council reports that optimized warehouse layouts can slash operational costs by 15-25% annually—money that goes straight to your bottom line.
These pallet racking solutions simplify the management of large volumes of identical stock-keeping units (SKUs) by creating dedicated storage zones for specific products. No more hunting through random aisles, wondering where someone stashed that critical inventory.
Choose LIFO for bulk storage where rotation doesn’t matter. Or FIFO when product expiration dates can make or break your operation. This flexibility allows you to align your warehouse racking strategy with your actual business needs, rather than forcing your operations to work around storage limitations that don’t make sense.
You can even use both systems in different areas of the same facility to optimize flow for various product types, because one size doesn’t fit all.
Available in structural or roll-formed steel configurations, these systems are fashioned to handle the most challenging warehouse environments and the heaviest loads.
Add pallet stops, seismic supports, and guide rails to meet strict safety standards while customizing dimensions to match your specific requirements.
Properly designed storage systems extend equipment life while significantly improving safety outcomes.
Refrigeration costs money. Drive-in racks excel at storing identical frozen items in ultra-high density, while drive-thru configurations support a first-in, first-out (FIFO) flow for perishables.
Drive-thru racking enables efficient turnover for items with short shelf lives, allowing for quick replenishment and preventing spoilage disasters. Drive-in systems handle non-perishable bulk items that move in large volumes without time pressure.
Keep materials organized with fewer aisles and better batch separation. Clear production areas and create efficient inventory zones for repeat builds.
Dense storage for high-volume SKUs makes managing seasonal surges more manageable without the need for costly facility expansion.
Perhaps you’re tired of explaining to upper management why you can’t accommodate more inventory, or frustrated by watching your team navigate crowded aisles during peak season. SRS-i’s drive-in racking and drive-thru racking systems have helped operations just like yours transform cramped warehouses into streamlined storage powerhouses.

Drive-in racks offer single-sided access with LIFO (Last-In, First-Out) flow, making them perfect for bulk storage where rotation doesn’t matter. Drive-thru racks allow access from both ends, enabling a FIFO (First-In, First-Out) flow that’s essential for perishables and items with expiration dates.
Absolutely. We design systems tailored to your needs. Our warehouse layout services team creates solutions that integrate seamlessly with existing operations.
Essential features include guide rails, pallet stops, reinforced entry points, and regular inspections. Comprehensive operator training is crucial since forklifts enter the rack structure directly.
