The critical integration of dynamic, gravity-driven flow systems in modern warehouse networks.
As modern distribution models migrate from simple storage to high-speed order fulfillment, traditional static shelves often become operational bottlenecks. Carton Flow Storage Systems represent a paradigm shift in density and cycle speed, utilizing inclined roller beds or wheel tracks to feed goods from the loading aisle (replenishment) to the picking aisle (discharge). Relying entirely on gravity, this system guarantees a strict First-In, First-Out (FIFO) inventory flow, essential for dated products, perishable food items, pharmaceutical lines, and high-velocity consumer goods.
By splitting feeding operations away from direct pick-faces, travel times for picking personnel are reduced by up to 40%. The result is a dramatically compacted facility footprint and a significant drop in operational labor costs. In an era dominated by rapid e-commerce expansion and high SKU diversification, carton flow lanes serve as the mechanical backbone for Pick-to-Light (PTL) setups and automated carton consolidation loops.
Under the hood of Dongguan Durack Logistics Equipment Co., Ltd.’s 35,000 m² Advanced Production Facility.
Founded in 2014, Dongguan Durack Logistics Equipment Co., Ltd. is a premier Chinese storage racking system manufacturer operating a 35,000 m² facility. Backed by 12 years of industry experience and 8 years of global export history, the company generates $28 million in annual export revenue. Our operations are supported by a strict quality assurance system using full-spectrum ultrasonic testing and load-bearing stress evaluations, overseen by 45 dedicated QC specialists. Building on a strong international trading background, our core markets span North America, Europe, and Southeast Asia. We maintain a reliable supply chain network of over 850 partners, catering primarily to third-party logistics (3PL) providers, automated warehouses, and large industrial distributors. Driven by an active R&D division with 65 specialized engineers, Durack offers full OEM/ODM customization options—including bespoke beam profiles, structural steel grades, and dynamic layout designs—launching over 120 new storage products last year.
Witness our vertically-integrated production pipeline, ensuring material stability, high precision tolerance levels, and surface protection.
Decoupling the mechanical calculations and profile configurations that support high-load dynamic gravity storage.
Our engineers adjust standard slope angles between 2.5% and 4.0% depending on carton weight and material friction levels. This eliminates packaging compression risks while ensuring consistent forward travel.
Deploying specialized high-density polyethylene (HDPE) wheels, or galvanized steel rollers for extreme loads, to minimize friction coefficients. Wheel tracks are engineered to fit standard structural shelf beams seamlessly.
Integrating mechanical separators keeps cartons in defined channels. Heavy-duty structural steel end-stops decelerate packages at the picking face to prevent product bounce and operational wear.
Designing structures compatible with pick-to-light, voice picking, and automatic guided vehicle (AGV) systems. This prepares standard operations for transitioning into fully computerized automated warehouses.
Adapting dynamic storage systems to target localized regional supply chain challenges and storage setups.
Integrating carton flow racks within assembly lines provides immediate parts access. This enables Just-In-Time (JIT) replenishment and clear Kanban system operations for fast-moving automotive parts.
High-density dynamic lanes operating in sub-zero environments maximize cold room density. This reduces cooling volume losses while preventing perishables from expiring, thanks to strict FIFO product rotation.
Structuring multi-tier carton flow pick modules allows processing of split-case orders. It integrates smoothly with belt conveyor loops to manage fast-moving SKUs during high seasonal demands.
Our commitment to safety and manufacturing precision is backed by strict engineering benchmarks.
Structural reliability in high-capacity warehouse racks is critical for operational safety. Our manufacturing processes utilize rigorous testing protocols, including ultrasonic weld inspections and load-bearing stress evaluations, overseen by our team of 45 quality control specialists.
Every structural system complies with global standards, including Europe's EN 15512 and the United States' RMI (Rack Manufacturers Institute) guidelines. This guarantees that our load ratings and material properties deliver safe, reliable performance under full structural loads.

Technical answers to help buyers and logistics engineers specify the right storage systems.
A: Standard installations use an incline between 2.5% and 4.0% (approximately 1.5° to 2.3°). Lighter carton boxes require a slightly steeper slope (up to 4.5%) to maintain rolling momentum, while heavier, rigid plastic totes roll smoothly at angles closer to 2.5%.
A: We integrate continuous full-length guide rails within each lane. Using staggered roller setups or plastic wheel lanes ensures the carton stays aligned, preventing skewed boxes from wedging against side profiles.
A: Yes. For variable SKU sizes, we recommend using full-width roller mats rather than single wheel tracks. This creates a continuous rolling surface, allowing cartons of different widths to travel down the same dynamic channel.
A: We offer hot-dip galvanized steel components, pre-galvanized profiles, and electrostatic powder coatings cured at 200°C. These treatments prevent oxidation, even in harsh cold storage facilities down to -30°C.
A: By presenting SKUs along a clean, dedicated picking line, carton flow systems organize inventory logic. When integrated with Pick-to-Light (PTL) systems, it reduces search times and helps keep order picking errors below 0.1%.
A: We install custom deceleration ramps and heavy-gauge mechanical end stops at the discharge point. For deep-lane configurations, we add impact-reducing rollers and lane-break separators to manage pressure from trailing boxes.
