Explore our foundational heavy-duty industrial racking and structural steel platform systems, precision engineered to integrate with high-density automated systems.
As global supply chains navigate labor shortages, soaring land acquisition costs, and complex inventory management cycles, traditional storage mechanisms are reaching their mathematical thresholds. The 4-Way Pallet Shuttle System (AS/RS) represents the peak of high-density automated warehousing.
Unlike traditional 2-way shuttle solutions that only traverse back and forth along single deep lanes, the 4-way shuttle moves both longitudinally and transversely. Utilizing cross-aisle transfer networks, a single fleet of shuttles can dynamically reach any storage location inside a multi-tier rack structure without forklift assistance. This structural adaptability increases floor-space utilization by up to 60% compared to selective pallet racking, and up to 30% compared to traditional double-deep layouts.
No two logistics distribution centers are identical. Ceiling heights, slab load capacities, warehouse seismic zones, SKU profiles, and operating temperatures (such as sub-zero cold food chain environments) require custom racking profiles and bespoke engineering designs.
As a premium OEM manufacturer, Shenzhen Lijin Storage Equipment Co., Ltd. offers customized structural steel thicknesses, custom-milled rail profiles with strict flatness tolerances (±0.5mm), and comprehensive sensor-integration plates to guarantee smooth shuttle travel and zero downtime.
An established global industrial infrastructure provider delivering elite-tier automated storage fabrication and structural design capabilities.
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.
Supported by a skilled team of 28 R&D engineers, Shenzhen Lijin delivers comprehensive OEM and ODM solutions tailored to unique warehouse layouts, seismic requirements, and capacity needs. Our engineering team launched over 85 new products and dynamic storage configurations last year, continuously setting new standards in space optimization and modern automated storage integration.
Backed by an experienced international trade background, 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. Our primary clients include large-scale logistics hubs, commercial distributors, third-party logistics (3PL) providers, and industrial equipment wholesalers.
Our direct export experience (over 8 years) guarantees seamless logistical management, customs handling, and structured dispatch of structural racking parts straight to job sites globally, minimizing on-site construction delays.
Every profile, upright, rail, and structural beam is fabricated using advanced automation equipment to maintain sub-millimeter tolerances required for 4-way shuttles.
Procurement directors seek more than competitive pricing; they prioritize structural reliability, material consistency, and geographical proximity to deepwater logistics hubs.
Lijin utilizes high-tensile Q235B and Q355B structural carbon steel sourced from leading domestic mills. These grades provide superior yield strength, ensuring low deformation rates and structural integrity under prolonged high stress.
Our automated electrostatic powder coating lines provide uniform coating thicknesses (>60μm), preventing rust, oxidation, and scratches. Galvanized rail options are available to handle the humidity demands of cold storage facilities.
Situated in Shenzhen, China, our proximity to major global ports (Yantian, Shekou) reduces transport times, optimizes container loading schemes, and cuts intermodal logistics freight costs.
Deploying automated high-density rack networks requires strict adherence to regional structural laws and manufacturing safety standards. Shenzhen Lijin structures are engineered using Finite Element Analysis (FEA) to confirm compliance with global and national regulatory codes.
We provide remote design validation, detailed engineering calculations, and localized layout documentation to support your building permit applications and structural approvals.
From sub-zero food warehouses to fast-moving e-commerce distribution nodes, 4-way systems maximize throughput across various industries.
Cold warehouse volume is expensive to run. Operating 4-way systems inside cold rooms reduces refrigerated air volume by minimizing overhead clearances and removing forklift aisles. Special low-temperature steel alloys and condensation-resistant finishes prevent brittle fractures.
Third-party logistics providers (3PLs) handle diverse SKU shapes, weights, and rotation profiles. Our OEM racking adjusts to varying pallet sizes and accommodates high-speed SKU rotation, supporting FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) retrieval paths.
With rapid order processing demands, e-commerce networks rely on high throughput. The 4-way layout handles deep storage and quick transport, routing items rapidly to automated pick-to-light packing desks to optimize outbound speed.
Expert structural and operational answers to common inquiries from integration engineers and warehouse designers.
To avoid shuttle slips and sensor misreadings at high speeds (up to 2.0 m/s), rail profiles require a flatness tolerance within ±0.5mm over a 1000mm length, and structural deflection limits must be designed to a minimum of L/300. Lijin achieves this precision through automated roll forming and high-precision welding lines.
Our 28-person R&D team works with system integrators to adapt rack structures to specific shuttle sizes. We customize rail widths, support bracket heights, and vertical beam connections, ensuring your proprietary robotic shuttles fit seamlessly into our racking systems.
Yes. We perform structural calculations based on regional seismic zones (using EN 1998, RMI, or AS1170.4 guidelines). Upright columns are thickened, baseplate footprints are enlarged, and heavy-duty portal braces are added to protect the racking from lateral force loads.
We supply Mill Test Certificates (MTC) matching standard EN 10204 3.1 for every batch. This guarantees chemical compositions and physical properties (tensile strength, yield point, elongation) meet our specifications before processing begins.
We recommend pre-galvanized profiles or specialized zinc-rich, low-bake powder coatings. These treatments maintain elasticity and resist cracking at sub-zero temperatures, preventing moisture from corroding the underlying steel.
Our standard configurations support payload weights of up to 1,500kg per pallet. If higher loads are needed, we customize dynamic load distributions by utilizing heavy-walled structural box channels and specialized high-strength connectors.
