Pallet Flow Racking System
High-density gravity-fed FIFO pallet storage that automatically rotates inventory — loaded from the back, picked from the front. Zero energy, zero forklift entry, 100% date-code accuracy for perishable, pharmaceutical, and high-throughput distribution operations.
What Is Pallet Flow Racking?
Pallet flow racking — also known as gravity flow rack, live pallet racking, or dynamic pallet storage — is a high-density storage system that uses inclined roller or wheel tracks to move pallets automatically from the loading end to the picking end using gravity alone. This ensures perfect First-In, First-Out (FIFO) inventory rotation without any mechanical power or forklift lane entry.
Pallets are loaded at the higher back end of the lane and glide forward on roller conveyors at a controlled speed (regulated by speed controllers and brakes) to the lower front face for picking. When a front pallet is removed, the next pallet in line advances automatically — providing a continuous, self-replenishing pick face with zero energy consumption.
Gieantech designs and manufactures custom pallet flow racking systems for cold storage warehouses, food and beverage distribution, pharmaceutical logistics, and high-volume 3PL operations across 57+ countries worldwide.

Automatic FIFO Rotation
Gravity ensures the first pallet loaded is always the first picked — critical for perishable goods, pharmaceuticals, and date-sensitive inventory management.
85% Space Utilization
Deep-lane storage with only 2 aisles (one loading, one picking) delivers 85%+ space utilization — far superior to selective racking's 45-50%.
Zero Energy Consumption
100% gravity-powered operation — no motors, no electricity, no batteries. Roller tracks and controlled incline move pallets automatically with zero energy cost.
Speed Controllers & Brakes
Integrated centrifugal speed controllers and end-of-lane braking systems regulate pallet speed for safe, controlled flow regardless of pallet weight.
Cold Storage Optimized
Engineered for -30°C environments with low-temperature rated rollers, galvanized steel, and stainless steel options. Minimize freezer door openings.
Separate Load/Pick Aisles
Loading and picking happen in different aisles — eliminates forklift congestion, improves safety, and doubles throughput versus single-aisle systems.
Self-Replenishing Pick Face
When a pallet is picked, the next pallet automatically advances to the pick face — no waiting, no manual replenishment, continuous workflow.
WMS Integration Ready
Lane-level inventory tracking with barcode and RFID compatibility. Real-time stock visibility per lane for warehouse management system integration.
Pallet Flow Configurations
Choose the right gravity flow system for your warehouse layout, pallet type, product weight, and temperature requirements.
Full-Width Roller Track
Heavy-duty steel rollers spanning the full pallet width on inclined steel channels. Best for heavy pallets (1000-2000 kg) and uniform pallet sizes. Robust, low-maintenance, and ideal for high-weight food and beverage distribution.
Skate Wheel Track
Inline skate wheels mounted on steel channels provide smooth, low-friction pallet movement. Lighter duty (500-1200 kg), lower cost, and excellent for lighter pallets and ambient temperature warehouses.
Cold Storage Pallet Flow
Specially engineered for -25°C to -30°C environments. Low-temperature rated rollers, galvanized or stainless steel components, and sealed bearings. Maximizes cubic storage in expensive cold storage space.
Multi-Level Pallet Flow
3-5 flow levels stacked vertically for maximum storage density. Each level operates independently with its own roller tracks, speed controllers, and braking system. Best for high-throughput distribution centers.
System Components
Every Gieantech pallet flow racking system is built from precision-engineered components for reliable, maintenance-free gravity flow operation.
Roller / Wheel Tracks
Heavy-duty galvanized steel roller conveyors or skate wheel lanes mounted on inclined steel channels. Multiple track widths (70-120mm rollers) matched to pallet size and weight.
Speed Controllers
Centrifugal speed regulators integrated into the roller tracks control pallet descent speed (typically 0.1-0.3 m/s) regardless of pallet weight, ensuring safe, consistent flow.
End-of-Lane Brakes
Hydraulic or mechanical pallet separators and braking devices at the pick face bring pallets to a controlled stop, preventing impact damage and ensuring safe picking.
Racking Frame Structure
Heavy-duty upright frames (2.0-2.5mm gauge) and step beams form the structural backbone. Adjustable beam heights accommodate different pallet heights and flow level configurations.
Entry Guides & Rail Guards
Flared pallet entry guides at the loading end and side rail guards along lanes prevent misalignment and keep pallets centered during gravity descent.
Pallet Stops & Backstops
Rear pallet stops prevent overloading, while front pallet stops position the pick-face pallet precisely. Optional lane-full indicators alert operators when lanes reach capacity.

How Pallet Flow Works
A gravity-powered FIFO system — pallets are loaded from the back and automatically flow to the front pick face for retrieval.
Load from Back Aisle
Forklift places pallets onto the elevated back (loading) end of the inclined roller lane. Entry guides center the pallet automatically.
➔Gravity Flow Forward
Pallets glide forward on roller tracks at a controlled 3-5% incline. Speed controllers regulate descent to 0.1-0.3 m/s regardless of pallet weight.
➔Controlled Braking
End-of-lane brakes and pallet separators bring each pallet to a safe, controlled stop at the front pick face — preventing impact and product damage.
➔Pick from Front Aisle
Forklift retrieves the front pallet from the lower pick-face end. The next pallet in the lane automatically advances to the pick position — FIFO guaranteed.
True FIFO — Zero Manual Rotation
Unlike push back racking (LIFO) or drive-in racking (LIFO), pallet flow guarantees First-In, First-Out rotation automatically. The oldest pallet is always picked first — critical for perishable goods, pharmaceuticals, and any inventory with expiration dates. No forklift enters the lanes, and no manual stock rotation is ever needed.

Frequently Asked Questions
Everything you need to know about pallet flow racking and gravity-fed FIFO storage systems from Gieantech.
The key difference is inventory rotation method. Pallet flow racking provides FIFO (First-In, First-Out) — pallets are loaded from the back and picked from the front, ensuring the oldest stock is always picked first. Push back racking provides LIFO (Last-In, First-Out) — pallets are loaded and picked from the same front aisle, meaning the most recently stored pallet is picked first. Choose pallet flow when date-code accuracy and expiration management are critical (food, pharma, dairy). Choose push back when FIFO is not required and you want lower cost per pallet position.
Standard pallet flow lanes range from 2 to 20+ pallets deep. The optimal depth depends on your SKU velocity, daily throughput, and warehouse layout. High-volume, low-SKU operations (beverages, dairy) often use 10-20 pallet deep lanes. Multi-SKU warehouses may use 3-6 pallet deep lanes. Our engineers will calculate the ideal lane depth based on your inventory turnover rate and picking frequency to avoid dead stock at the back of lanes.
Our pallet flow systems support pallet weights from 500 kg to 2,000 kg. The roller track type, speed controller specification, and braking system are all sized according to your maximum pallet weight. Heavier pallets (1,500-2,000 kg) typically use full-width steel rollers, while lighter pallets (500-1,200 kg) can use skate wheel tracks for lower cost. All systems include speed controllers calibrated to your specific pallet weight range.
Speed controllers are centrifugal braking devices integrated into the roller tracks at regular intervals. As a pallet moves over them, centrifugal force activates a braking mechanism that limits the pallet speed to 0.1-0.3 m/s — regardless of pallet weight. Heavier pallets generate more braking force, so the speed remains constant. This is a purely mechanical system requiring zero electricity or maintenance, and it prevents pallets from accelerating uncontrolled down the inclined lane.
Yes, pallet flow is one of the best systems for cold storage and freezer environments (-25°C to -30°C). Benefits include: maximizing expensive cold storage cubic space (85%+ utilization), separate loading and picking aisles that reduce freezer door openings, zero energy consumption (no batteries to charge in the cold), and sealed bearings that perform reliably at low temperatures. We use galvanized steel or stainless steel components for cold storage applications.
Pallet flow systems work with standard EUR pallets (1200×800mm), US pallets (48×40 inch / 1219×1016mm), and custom pallet sizes. The critical requirement is that pallets have smooth, flat bottom boards that interface cleanly with the rollers or wheels. Plastic pallets work well due to their consistent dimensions. Damaged or warped wood pallets can cause flow issues — we recommend GMA Grade A or Grade B pallets for optimal performance.
Pallet flow racking is very low maintenance. The gravity-powered system has no motors, no electrical components, and no batteries. Recommended maintenance includes: visual inspection of roller tracks and speed controllers every 6 months, checking for damaged or stuck rollers, cleaning debris from lanes, inspecting end-of-lane brakes, and verifying structural bolt tightness annually. Speed controller replacement is typically needed only after 10+ years of heavy use.
Minimum order quantity is 30 lanes (negotiable for first-time orders). Standard lead time is 25-40 days from order confirmation to factory dispatch, depending on system size and roller specifications. We support T/T (30% deposit, 70% before shipping), L/C at sight, and Alibaba Trade Assurance. Shipping terms include FOB Dongguan, CIF, and DDP delivery to your warehouse door.
In some cases, yes. If your existing selective pallet racking has sufficient upright frame capacity and depth, roller flow tracks can be installed into the existing bay structure. This requires engineering analysis of the existing frame capacity, beam connection compatibility, and floor slab adequacy for the additional load concentration. We offer retrofit assessment services — send us your existing racking details and we will evaluate feasibility and provide a conversion quotation.
