Explore our high-performance structural steel pallet storage, engineered for safety, density, and swift logic cycle executions.
Shenzhen Yuanzhang Trading Co., Ltd. is a global benchmark in industrial warehousing optimization.
Established in 2015, Shenzhen Yuanzhang Trading Co., Ltd. is a leading manufacturer and exporter specializing in heavy-duty warehouse racking and customized industrial storage systems. Operating out of a state-of-the-art 35,000 m² production facility, we bring 12 years of deep industry expertise and 8 years of dedicated international trade experience to global logistics and commercial storage projects.
Driven by technical excellence, our operations are backed by a robust research and development center staffed with 25 expert R&D engineers. Demonstrating our strong commitment to innovation, we launched over 150 new storage solutions last year alone. We offer fully versatile OEM/ODM custom options, including specialized dimensions, weight capacity adjustments, surface coatings, and modular structural designs to meet diverse client requirements.
Quality and reliability form the foundation of our business. We enforce strict multi-stage quality control—utilizing advanced automated ultrasonic testing, raw material stress analysis, and load-bearing fatigue assessments executed by a dedicated team of 45 QA/QC inspectors.
Gravity flow racks, also known as pallet flow racks, leverage gravity to automate inventory rotation. Our proprietary structural engineering translates potential energy into seamless dynamic motion, guaranteeing 100% FIFO (First-In, First-Out) operations.
The declination angle of our flow tracks is calibrated between 3% and 4%. This gradient maintains torque on heavier pallets without causing excessive acceleration. Under Euler-Bernoulli beam theory, our upright frames resist vertical deflection to ensure consistent pitch across multi-level racks.
To eliminate unsafe descent velocities, self-adjusting speed controllers are installed at fixed intervals (typically every 1 to 2 pallet lengths). These dampers generate an internal magnetic opposition matching the kinetic input of the pallet, ensuring a controlled, uniform crawl.
Our racks feature mechanical separators at the picking face to isolate the pressure of the remaining queued pallets. Removing the front pallet unlocks the mechanism, releasing the second pallet. Upgraded end stops absorb residual impact forces safely.
We engineer purpose-built, high-density storage solutions to solve space constraints, optimize throughput, and reduce operating costs across diverse sectors.
Cold storage is highly resource-intensive. Gravity flow systems maximize volume density, minimizing the energy footprint of temperature-controlled air. With a design operational threshold of -30°C, our steel racks utilize specialty structural components that resist low-temperature embrittlement.
Compliance with FDA, WHO, and local pharmaceutical standards requires strict product rotation. Our 100% FIFO gravity systems ensure that batch numbers and expiration dates are distributed in the exact order of receipt, minimizing waste and product expiration risks.
For high-throughput distribution hubs, gravity flow lanes serve as high-capacity buffers. By segregating loading aisles from picking aisles, we decrease forklift travel times and eliminate structural interference, increasing replenishment speeds by up to 35%.
Our 35,000 m² manufacturing plant in Shenzhen integrates automated production processes to deliver structural integrity, anti-corrosive finishes, and rapid lead times.
Deploying large-scale industrial racking globally requires strict alignment with structural design codes and regulatory frameworks.
We engineer and verify our gravity systems in accordance with key global regulatory frameworks: ANSI/RMI MH16.1 (USA), EN 15512 (Europe), and AS4084 (Australia). Each customized system includes detailed calculations verifying wind loading and seismic drift tolerances.
Long-distance maritime shipping exposes metal components to salt corrosion and physical impact. We protect our uprights and beams using multi-layer polyethylene wrapping, heavy-duty edge guards, and custom steel-strapped pallets to guarantee scratch-free delivery.
Through our network of global partners, we provide structural consulting and installation guidance in over 30 countries. Our expert field engineers review site leveling, floor anchoring limits, and provide step-by-step assembly oversight for rapid, compliant sign-off.
The future of material handling lies in real-time tracking, structural health monitoring, and seamless hybrid automation. We are shaping the next generation of gravity-driven storage systems.
By integrating wireless sensors into our roller units, we track rotational speed and detect pallet stalls. The system automatically alerts the warehouse management software (WMS) when maintenance is required on specific storage lanes.
Combining gravity rails with battery-operated radio shuttles maximizes lane depths up to 40 meters. Shuttles manage deep pallet transfers, while gravity slopes feed picking tunnels, providing high throughput and storage density.
Strain gauge sensors placed on the main support columns continuously monitor dynamic loads and beam deflection. If structural thresholds are exceeded, the system flags the issue to prevent failure.
