Gravity Flow Rack Systems

It’s a high-density storage solution that uses gravity to do the heavy lifting. Products load at one end and move automatically to the other, so your team gets to stock faster, with less walking and no extra equipment.

Here’s how it works:

• Sloped, inclined lanes carry product on rollers or wheels from the load end to the pick end
• New stock loads at the back and feeds forward automatically as items are picked
• Built-in first-in, first-out (FIFO) rotation keeps older inventory moving first
• Less bending, reaching, and unnecessary movement for your team

Gravity flow racks are a strong fit for operations handling palletized loads or individual cartons at high volume.

What Are the Benefits of a Gravity Flow Rack System?

Space efficiency. Gravity flow lanes store product multiple pallets or cartons deep in a single lane, so you pack more SKUs into less floor space than static shelving allows.

Labor reduction. Automatic feed means less forklift travel and re-handling. Pickers work the front of the lane while replenishment happens from the back, cutting the walking and searching that eats into a shift.

Automatic FIFO rotation. Stock rotates itself in load order, so older inventory always picks first. That matters most for perishables, temperature-sensitive goods, or anything with a shelf life.

Ergonomics and safety. Fewer manual lifts and shorter travel distances mean less strain on your team. OSHA identifies reduced bending, reaching, and repetitive motion as a direct way to cut warehouse injury risk, and a gravity-fed system does that by design.

What’s the Difference Between Pallet Flow and Carton Flow Racks?

Two smart systems—one shared goal: efficient, organized, FIFO-based storage. The key difference? What you’re storing and how you’re handling it. Both systems use gravity and rollers, but one is built for heavy-duty pallets, the other for smaller, faster-moving items.

Pallet Flow Rack: For Bulk Loads and High-Volume Operations

Pallet flow racks are built to handle full pallet loads with ease. Using heavy-duty roller tracks, they create a seamless flow from loading to picking, cutting down forklift travel and speeding up throughput. These systems are a go-to for distribution centers, cold storage, and manufacturing environments where volume and rotation matter.

Use it when you:

• Store bulk or palletized inventory
• Run a high-volume facility
• Need FIFO storage for perishables or time-sensitive goods

Carton Flow Rack (aka Case Flow Rack): For Small Units and Fast-Pick Operations

Carton flow racks are designed for order picking, especially in e-commerce, retail, or fulfillment centers. They handle smaller boxes, cartons, or individual items, keeping them neatly organized and easy to access. With high-density lanes, they help streamline picking and reduce walking time.

Use it when you:

• Handle piece-picking or fast-moving SKUs
• Work with smaller cartons or cases
• Want faster, more accurate picking

Common Questions About Gravity Flow Racks

What Is a Gravity Flow Rack?

A gravity flow rack is a storage system that uses sloped, roller-equipped or wheel-equipped lanes to move product automatically from the load end to the pick end. It’s built for FIFO rotation and works for both palletized loads (pallet flow) and cartons or individual items (carton flow).

What’s the Difference Between Pallet Flow and Carton Flow Racks?

Pallet flow racks handle full pallets and bulk loads. Carton flow racks handle smaller cartons, cases, and individual items for order picking. See the breakdown above for which one fits your operation.

How Much Does a Gravity Flow Rack System Cost?

Cost depends on lane depth, load capacity, materials, and how much customization your layout needs, so there’s no single set price for a gravity flow system. For a broader sense of what drives pallet racking costs, see our pricing guide.
