Explore our diverse manufacturing capabilities, ranging from high-capacity industrial shelving to specialized heavy-duty commercial display racks.
In the contemporary landscape of global logistics, space optimization is no longer just a warehouse design consideration; it is a critical competitive lever. Pallet Flow Storage, also known as gravity flow racking, represents the pinnacle of high-density dynamic storage. By utilizing a slight incline (typically 3% to 4%) and roller tracks, these systems leverage the natural force of gravity to automatically move pallets from the loading aisle (charge face) to the picking aisle (discharge face).
Unlike standard selective racking, which requires multiple aisles and sacrifices up to 60% of potential floor space to forklift pathways, pallet flow systems achieve unparalleled density. They operate on a strict First-In, First-Out (FIFO) protocol, making them indispensable for industries handling perishables, high-turnover consumer goods, and temperature-sensitive chemicals. From a macro perspective, the global rise of automated distribution networks and the surging cost of cold storage real estate have positioned dynamic gravity flow solutions at the heart of modern supply chain architecture.
Guarantees absolute stock rotation. The oldest inventory is always presented first, eliminating product expiration risks and streamlining batch tracking.
Saves up to 60% of floor space compared to selective racking by consolidating storage lanes. Can support layouts ranging from 2 to over 20 pallets deep.
Equipped with centrifugal speed controllers to ensure pallets travel at a safe, controlled speed, preventing impacts and cargo damage.
Shenzhen Runda Racking Manufacturing Co., Ltd.
Established in 2015, Shenzhen Runda Racking Manufacturing Co., Ltd. is a premier manufacturer specializing in heavy-duty industrial shelving and high-density warehouse storage solutions. With over 11 years of deep industry expertise and 9 years of active global export experience, we deliver tailored racking systems to logistics hubs, distribution centers, and manufacturing plants worldwide.
Operating from a modern 35,000 square meter production facility, our operations are powered by a robust network of over 1,200 trusted supply chain partners. This enables us to achieve an annual export turnover of $28 million. Our primary markets span North America, Western Europe, Southeast Asia, and the Middle East, where we proudly serve industrial distributors, large-scale third-party logistics (3PL) operators, and direct enterprise buyers.
Quality and innovation drive our core philosophy. We maintain strict quality control through full-process sampling inspection, raw material stress testing, and load-bearing verification, backed by a dedicated team of 35 QC professionals. Innovation is led by our 18 experienced R&D engineers who continuously refine structural efficiency—releasing over 120 new and upgraded storage products last year alone.
We offer comprehensive OEM/ODM and full custom manufacturing services, including tailored load capacities, custom dimensions, corrosion-resistant powder coatings, and specialized seismic structural designs. Supported by our experienced international trade background, Shenzhen Runda provides seamless end-to-end service, from technical layout design to reliable global shipment execution.

From raw materials verification to automated coating and load-bearing QC, view our end-to-end manufacturing pipeline.
Ongoing structural load verification and structural component stress testing at Shenzhen Runda Laboratory.
We engineer systems to satisfy the most demanding regulatory frameworks across different target markets.
Our structures conform strictly to the Rack Manufacturers Institute (RMI) MH16.1 specifications. This includes full structural analysis for welded frames and beam-to-column connections, ensuring dynamic stability under seismic events (Seismic Design Categories A through F).
Engineered to comply with the European Federation of Materials Handling (FEM) and standard EN 15512 rules, verifying structural deflection profiles, safety coefficients, and minimum factor limits under maximum payload states.
Tested and audited under Australian Steel Storage Racking standards. This structural protocol ensures robust tolerance limits, column upright protection design, and mandatory safety labels identifying safe operating load metrics.
Different industries demand distinct parameters. We custom-engineer layouts to solve specific flow and environment constraints.
Operating inside temperatures down to -30°C. Runda uses structural low-temperature steel (Q355D/E) and grease-free, stainless-steel roller bearings that resist freezing to prevent roller seizure.
For high-throughput warehouses requiring quick dynamic stock rotation. Fast-rolling inline separations and safety ramps speed up staging operations, keeping materials moving smoothly.
Designed for dense weight loads. Heavy steel split-roller lanes and reinforced guide plates absorb the mechanical shock of heavy steel parts pallets dropped by forklifts.
As logistics operations transition toward total automation, Runda Racking is leading the research in integrating smart technology into traditional gravity-fed platforms. The future of pallet flow involves smart monitoring and safety feedback arrays. Our technical roadmap highlights two major areas of focus:
By blending traditional structural steel metallurgy with these emerging technologies, Shenzhen Runda guarantees that our storage designs remain a future-proof investment for modern logistics hubs.
Technical clarifications on system calculations, manufacturing options, and installation planning.
We primary source high-strength structural carbon steel Q235B and Q355B (equivalent to ASTM A36 and ASTM A572 Grade 50). This guarantees structural load reliability under high bending stresses and maintains structural stiffness for multi-level structural configurations.
Typically, the incline is set between 3.5% to 4% for standard wood pallets. However, the precise calculation depends on the pallet bottom condition, materials, and total weight. We conduct pre-shipping test runs using physical samples of your pallets in our testing bays to determine the optimal slope angle prior to structural fabrication.
We integrate centrifugal speed controllers at fixed intervals along each lane. These rollers exert a braking force that increases proportionally to the pallet's speed, keeping the descent controlled. At the exit face, we install structural pallet separators that isolate the first pallet from the pressures of the accumulating pallets behind it, ensuring safe extraction by forklifts.
Yes, we provide full custom layout configurations. Our 18 R&D engineers use Finite Element Analysis (FEA) software to design specialized uprights, custom beam sizing, custom colors, and special coatings. Contact us with your warehouse footprint and pallet drawings to receive a custom CAD layout.
Our 35 QC professionals conduct rigorous inspections, starting with incoming raw materials inspections, ongoing welding inspections, powder coat thickness checks, and load test verifications. Every structural component batch is tracked, ensuring absolute material traceability and adherence to industry regulations.
