Engineered to handle extreme loads, maximize warehouse height utilization, and streamline retrieval cycles.
Founded in 2015, Shenzhen Lijin Storage Equipment Co., Ltd. has grown to become a premier designer, manufacturer, and global exporter of high-load industrial warehouse storage systems. Operating from our state-of-the-art 35,000 m² manufacturing facility, we integrate structural engineering, automated production, and comprehensive logistics modeling to deliver world-class OEM and ODM solutions.
With more than 12 years of core industry expertise and over 8 years of dedicated direct export experience, we support global enterprise clients across North America, Western Europe, Southeast Asia, and the Middle East. Through strict adherence to ISO 9001:2015 standards and structural engineering principles, our solutions ensure optimal load distribution, spatial efficiency, and workplace safety.
Driven by product innovation, advanced structural design, and robust supply chain integration, our global export revenue reached USD 22 million last year, establishing us as a highly trusted strategic OEM partner for multi-national distribution hubs and logistics operators.
Retractable storage rack systems represent a pinnacle of space optimization for heavy, high-value, and awkwardly shaped industrial goods. Unlike standard static pallet racking, retractable systems incorporate mechanical slide-out shelves (often utilizing high-grade telescopic linear bearings and heavy-duty steel tracks) that allow individual drawers or shelves to be pulled clear of the rack structure. This design enables overhead cranes, hoists, and material handling equipment to easily access materials without requiring forklift maneuvers inside narrow aisles.
Our OEM retractable racking solutions are constructed with structural hollow section profiles and hot-rolled profiles (Q235B and Q355B steel grades) that offer a safety factor of 1.5 to 2.0 under full load capacity. The roll-formed frames and vertical supports are engineered to handle dynamic loads of up to 3,000 kg per shelf, reducing deformation and minimizing aisle blockages. When integrated into advanced manufacturing facilities, tooling storage layouts, or aerospace assembly floors, retractable racks can recover up to 70% of floor space otherwise lost to forklift clearance zones.

A multi-stage quality control workflow ensuring every component exhibits superior structural integrity.
Leveraging high-end automated machinery to secure repeatable dimensional tolerance within ±0.5mm.
Sourcing your storage infrastructure from Shenzhen Lijin grants you unparalleled access to the world’s most robust industrial steel supply chain and shipping networks. Based in the Pearl River Delta industrial cluster, we obtain high-tensile structural steel from top-tier mills under favorable material agreements. This ensures that even during global commodity price surges, we maintain highly competitive factory prices.
Additionally, our close proximity to the Port of Shenzhen (one of the largest container ports globally) reduces internal haulage costs, minimizes transit damage risks, and speeds up custom clearance cycles. We leverage Guangdong's dense network of specialized coating vendors, fastener manufacturers, and structural testing labs, allowing us to source premium auxiliary components with short lead times.
With 28 dedicated R&D engineers, we specialize in customizing structural configurations for unique warehouse footprints, low-ceiling basements, and high-security zones. Whether your storage setup must withstand seismic category D criteria or requires integrated mechanical lockouts to protect technicians from heavy loads, our R&D team can model the stress and deflection limits using FEA (Finite Element Analysis) software prior to mass production.
Last year alone, we developed over 85 customized configurations, including dynamic pipe cantilever systems, adjustable sheet metal drawer units, and motorized roll-out heavy mold platforms. This rapid modeling capacity allows us to transition from structural layout approval to sample fabrication in as little as 14 business days.
Operating a warehouse system requires strict alignment with localized safety and structural codes. At Shenzhen Lijin, we engineer our rack solutions to satisfy international guidelines, including the Rack Manufacturers Institute (RMI) standards in North America, EN 15512 standards in Europe, and AS4084 regulations in Australia. We provide certified calculations for floor slab load bearing, anchor pull-out capacity, and seismic drift ratios.
To assist your project from drawing to handover, we offer global local-support frameworks, including:
Our quality department is staffed by 35 certified QA/QC professionals who carry out multi-stage testing before dispatch. Raw steel sheets and tubes undergo ultrasonic thickness testing and chemical composition analysis upon entering our warehouse. During fabrication, we inspect welding penetration levels via non-destructive dye checks and laser dimensional analysis.
Additionally, each rack project is subjected to load-testing on our custom static-load test rig. Here, frames are loaded with up to 1.5 times their rated load limits to verify deflection calculations. Our powder coatings are tested for thickness (minimum 70-80 microns), adhesion strength (cross-cut test), and salt spray resistance, ensuring our racking systems can endure decades of industrial usage without peeling or oxidizing.
The industrial storage landscape is moving rapidly toward automation, safety, and floor density optimization. In high-cost urban zones, building traditional warehouse extensions is no longer financially viable. As a result, businesses are utilizing taller spaces, and incorporating overhead cranes and specialized hoist-retrievable cantilever systems. The integration of IoT sensors within heavy-duty racking allows real-time monitoring of shelf weight limits and detects structural shifts caused by collision, improving safety standards in modern facilities.
Furthermore, ESG (Environmental, Social, and Governance) targets are driving the demand for sustainable, long-cycle storage assets. Shenzhen Lijin addresses this trend by utilizing recyclable structural steel, eco-safe powder formulations, and designing our racks for modular redeployment, meaning you can easily reconfigure shelf heights or expand your layout as your inventory footprint changes.
Automotive stamping presses require heavy molds and dies (often weighing over 2 tons each) stored within arm's reach. Retractable roll-out shelves allow overhead cranes to pull the tool straight up, cutting die-change time from hours to minutes.
Traditional pipe bundles require significant floor space. Our customized cantilever racking systems allow long tubes and bar stock to be kept vertically or in high-density bins, preventing deformation and simplifying sorting.
Cold storage facilities operate at high energy costs, demanding maximum volume density. Our galvanized drive-in and dynamic platform racking systems prevent structural freezing failures and perform reliably down to -30°C.
