Engineered for maximum spatial efficiency, safety compliance, and robust loading capacity.
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.
Lijin's engineering excellence is focused on solving vertical space constraints. By implementing structural steel mezzanine floor systems, we assist industrial plants, logistics hubs, and commercial centers to expand their usable area by 100% to 300% without structural expansions.
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.
Supported by a skilled team of 28 R&D engineers, Shenzhen Lijin delivers comprehensive OEM and ODM solutions tailored to unique layouts, seismic requirements, and capacity needs. Our team launched over 85 new products last year.
Bridging spatial architectural gaps across global logistics networks, automated fulfillment hubs, and heavy assembly lines.
In modern third-party logistics, utilization of vertical cube space is directly tied to profit margins. Our rack-supported mezzanines integrate seamlessly with vertical conveyors, spiral chutes, and AGV (Automated Guided Vehicle) runways, creating multi-tiered processing zones that handle thousands of picks per hour.
Integrating dynamic assembly lines on elevated steel platforms requires precise deflection controls. Utilizing structural H-beams and hot-rolled components, we design rigid, vibration-isolated manufacturing platforms capable of handling static machinery and dynamic crane operations safely.
Designed for high-density storage of mixed-size items, our multi-level shelving mezzanines leverage customized configurations. By adding tire racks, small-part bins, and long-span levels on a single mezzanine base, automotive distributors can consolidate operations and scale storage SKU density by up to 200%.
From high-grade raw steel inspection to state-of-the-art automatic powder coating lines, discover our comprehensive fabrication lifecycle.
Lijin mezzanines are built using high-strength carbon structural steels, specifically Q235B and Q355B. These steel classifications are widely preferred in heavy-load manufacturing for their superior yield strengths, excellent weldability, and structural ductility.
Our columns are fabricated from heavy-gauge structural square tubes or hot-rolled H-beams. These elements are designed using advanced structural calculation software (such as ANSYS and AutoCAD) to withstand rigorous static and dynamic load distributions. We calculate structural deflection limits strictly based on the L/240 or L/360 criteria (maximum displacement limits), ensuring our platforms prevent structural fatigue, even under continuous forklift or heavy material handler movements.
The floor choices include solid steel plates, perforated grating panels, or heavy-duty wood composites. Perforated gratings offer a dual advantage by promoting optimal air circulation and enabling fire sprinkler systems to function across all levels without obstruction, conforming strictly to NFPA safety standards.
Exporting globally requires meeting diverse local construction, mechanical, and safety regulations. Lijin designs and manufactures systems following regional load codes, wind velocities, and seismic zoning maps:
Pioneering spatial digital twins, modular structural designs, and sustainable warehouse engineering.
We are developing bolt-together mezzanine designs that minimize on-site welding by up to 95%. This drastically cuts installation downtime and allows systems to be dismantled, expanded, or relocated as businesses grow.
By utilizing Building Information Modeling (BIM), our clients receive precise digital twins of their mezzanine systems. This enables automated clash detection with overhead HVAC, lighting, and electrical mains prior to manufacturing.
Lijin is transitioning to zero-VOC electrostatic powder coatings and sourcing carbon-efficient recycled steel. This helps clients achieve LEED certifications for green warehouse operations.
