Engineered for dynamic pallet control, high load capacities, and maximum spatial layout utilization.
Established in 2015, Shenzhen Lijin Storage Equipment Co., Ltd. is a leading enterprise specializing in the design, manufacturing, and global distribution of heavy-duty warehouse racking systems, automated storage solutions, and industrial shelving. Spanning a state-of-the-art facility of 35,000 m², we have developed into a trusted global supply chain partner with over 8 years of direct export experience and more than 12 years of deep industry expertise. Driven by innovation and quality, our global revenue reached USD 22 million last year.
Our commitment to structural durability and efficiency has positioned us as the preferred choice for industrial warehousing. By utilizing high-yield strength structural steel and cutting-edge design methodologies, we engineer gravity racking solutions that minimize operational bottlenecks and optimize floor footprint density by up to 60% compared to traditional static systems.
Our core markets span North America, Western Europe, Southeast Asia, and the Middle East. We maintain strong strategic relationships with over 850 supply chain partners globally, servicing large-scale logistics hubs, commercial distributors, third-party logistics (3PL) providers, and industrial equipment wholesalers.
Understanding the physics, structural engineering, and dynamics of FIFO (First-In, First-Out) live storage systems.
Gravity racking relies on a precise gradient incline (typically between 3.5% and 4.0%) to ensure controlled movement of heavy pallets. Our structural engineers utilize customized calculations factoring in pallet composition, total load weight (up to 2,000kg per pallet), and friction coefficients to define the optimal lane incline, preventing static lockup or runaway speeds.
To protect inventory and racking structural integrity, dynamic brake rollers (speed controllers) are integrated along the lane. As the pallet rolls down under gravity, these centrifugal brake systems restrict maximum velocity to a safe, controlled speed (typically < 0.25 meters per second), ensuring steady and linear descent.
At the discharge face, a heavy-duty mechanical separator isolates the lead pallet from the hydrostatic pressure of the trailing pallets in the lane. This allows the forklift driver to safely extract the front pallet without back-pressure, preventing load damage and significantly speeding up throughput cycles.
| System Component / Parameter | Standard Specifications | Industrial High-Load Adaptations |
|---|---|---|
| Incline Slope Range | 3.0% to 4.2% (Adjustable based on load parameters) | Customized slope angles tailored for temperature-controlled storage |
| Load Capacity Per Pallet | 500 kg to 1,500 kg | Heavy-duty configurations up to 2,200 kg per pallet position |
| Braking Distance & Control | Centrifugal speed controller every 2 to 3 pallet positions | Continuous dynamic braking rollers for deep lane storage (> 15 pallets) |
| Steel Grade & Upright Options | High-yield Q235B steel, cold-rolled profiles | Q355B high-tensile structural steel for seismic & sub-zero conditions |
Procuring gravity racking systems directly from a leading Chinese manufacturer like Shenzhen Lijin delivers significant cost and quality advantages. Leveraging China's robust raw material supply chain, we secure top-grade Q235B and Q355B structural steel directly from state-owned mills, guaranteeing consistent chemical properties and mechanical performance.
Our 35,000 m² factory integrates full-process automation. From multi-station high-speed roll forming lines to automated laser cutting and robotic welding, we maintain tight tolerances within ±0.5mm. This high precision is crucial for gravity flow systems, where minor misalignment can cause pallet jams.
Additionally, our geographical location in Shenzhen, adjacent to major international deepwater ports (Yantian and Shekou), minimizes domestic transport times and global shipping costs, providing a streamlined path for efficient international deliveries.

Providing customized high-density storage solutions across diverse global industry sectors.
In high-cost, temperature-controlled facilities, maximizing spatial volume is critical. Our gravity racking systems use low-temperature grease on roller bearings and corrosion-resistant powder coatings to perform reliably down to -30°C, supporting dense FIFO inventory rotation for perishable items.
Strict batch control is vital for products with expiration dates. By providing natural FIFO (First-In, First-Out) flow lanes, gravity racking ensures that older production batches are automatically discharged first, reducing waste and simplifying warehouse inventory management.
Just-in-time manufacturing requires immediate access to sub-assembly units. Gravity racking provides designated flow lanes for quick component identification, ensuring organized replenishment cycles and keeping assembly line feeds moving smoothly.
How IoT integration, automation, and advanced structural engineering are shaping the next generation of logistics.
The warehousing industry is shifting toward full automation. Modern gravity racking systems are no longer isolated structures; they are increasingly designed to integrate with AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots).
By pairing gravity flow racks with robotic pickers, operations can run 24/7 without manual forklift intervention. Additionally, the development of smart speed controllers with built-in sensors allows managers to monitor pallet descent speeds and line capacities in real time, shifting operations from reactive troubleshooting to predictive maintenance.
Environmental sustainability is also driving the adoption of passive gravity systems. By using gravity to move pallets instead of electricity, these systems significantly reduce a facility's carbon footprint, helping businesses meet corporate ESG goals while saving on energy costs.
Ensuring safety and reliability under heavy loads, day in and day out.
At Shenzhen Lijin, safety is central to our engineering. We enforce a rigorous, multi-stage quality control system—including ultrasonic non-destructive testing, automated weld inspection, laser dimensional checking, and heavy-load endurance testing. Backed by an in-house quality inspection team of 35 dedicated professionals, every batch meets international safety and structural standards, ensuring maximum load-bearing efficiency and long-term stability.
All designs comply with major international design codes, including the European FEM 10.2.02 guidelines, American RMI specifications, and Australian AS4084 standards. Our in-house R&D team of 28 engineers uses finite element analysis (FEA) to simulate wind loads, seismic forces, and dynamic impacts, customizing each system's structural members to perform reliably in demanding operational environments.
