Explore our high-performance, heavy-duty warehouse structural platforms, racking systems, and dynamic storage configurations engineered for industrial durability.
In the era of hyper-velocity order fulfillment, e-commerce escalation, and third-party logistics (3PL) optimization, traditional static shelving is rapidly becoming an operational bottleneck. Carton Flow Storage Systems—also known as gravity-fed flow racks—represent a high-density, dynamic storage solution designed specifically for split-case picking, high-throughput assembly lines, and order consolidation zones.
Utilizing a sloped frame equipped with high-durability roller tracks or wheel beds, Carton Flow Systems leverage gravity to automatically slide inventory from the loading aisle (replenishment face) to the picking aisle (discharge face). This structural design secures strict First-In, First-Out (FIFO) stock rotation, minimizing product deterioration, preventing stock obsolescence, and reducing internal travel times for picking personnel by up to 40% compared to traditional static racking configurations.
As a leading OEM and ODM manufacturer, our structural configurations are engineered to operate seamlessly with standard warehouse racking, conveyor pick interfaces, pick-to-light setups, and autonomous mobile robot (AMR) fleets. We specialize in tailoring custom slopes, impact decks, and roller divisions to ensure compatibility with varied packaging types—including corrugated cartons, plastic bins, and heavy-duty industrial totes.
By eliminating multiple service aisles, carton flow systems compress floor footprints by up to 50%. The continuous presentation of pick faces maximizes vertical clear space and increases SKU density per square meter.
Operations personnel spend up to 75% of their shift walking when retrieving from static layouts. Carton flow brings stock directly to the pick face, dramatically minimizing unproductive travel time.
Particularly critical in cold storage, food & beverage, pharmaceuticals, and high-tech manufacturing, where expiry dates and batch serialization require absolute chronological picking order.
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. Backed by over 8 years of direct export experience and more than 12 years of deep industry expertise, we maintain strong strategic relationships with over 850 supply chain partners globally.
Engineered to withstand rigorous daily logistics operations, our systems integrate high-grade materials and structural engineering.
We manufacture roller tracks using virgin HDPE, polypropylene, or galvanized steel. HDPE wheels are fitted with precision bearings to maintain minimal rolling resistance, allowing cartons to flow smoothly even on gentle slopes (2% to 4.5% grade).
Our uprights and beams are fabricated from premium Q235B or Q345B carbon steel. Our roll-formed upright structures undergo strict dimensional verification, ensuring load capacities of up to 4,000 kg per bay depending on profile configurations.
Every structural steel component is subjected to a multi-stage pre-treatment wash followed by a thermosetting epoxy electrostatic powder coating (thickness > 60 microns), guaranteeing superior wear, scratch, and corrosion resistance.
No two warehouse operations are identical. Our dedicated engineering department leverages advanced CAD and 3D modeling tools to design customized carton flow configurations, providing tailormade options for:
| Frame Load Capacity | 1,000 kg - 4,000 kg per bay |
| Roller Material Options | HDPE, Polypropylene, Galvanized Steel |
| Roller Track Widths | Customized from 300mm to 1200mm |
| Incline Angle range | 2° to 6° (Adjustable) |
| Seismic Configurations | Custom structural engineering (AS4084 / RMI compliant) |
| Corrosion Protection | Electrostatic Powder Coating (RAL colors customizable) |
From standard high-grade raw steel sourcing to automated electrostatic powder coating lines, witness our transparent manufacturing steps.
Analyzing challenges and providing tailored strategic architectures for high-capacity warehouse hubs.
Fast-moving, multi-SKU picking is standard in e-commerce fulfillment. Our carton flow racks integrate seamlessly with pick-to-light technology, reducing picking errors and optimizing rapid transit cycles. By minimizing the travel footprint, our systems enable lightning-fast order fulfillment rates.
Cold storage volume is expensive. Carton flow racking compresses the footprint while maximizing inventory density. This structural design ensures pharmaceutical batches and temperature-sensitive food items move in chronological order, reducing the risk of stock loss from expiration.
In manufacturing assembly operations, kitting carts and components must reside within immediate reach of technicians. Carton flow tracks deliver heavy-duty components right to the assembly point, promoting ergonomic safety and reducing operator fatigue.
Exporting structural steel systems globally demands deep structural compliance knowledge. At Shenzhen Lijin, we prioritize quality assurance protocols that meet strict European (FEM 10.2.02, EN 15512) and North American (RMI, ANSI MH16.1) safety standards.
Our quality control program enforces a rigorous, multi-stage inspection scheme. Every production batch is subject to ultrasonic non-destructive weld testing, paint thickness gauges, laser coordinate dimension checks, and load deflection tests. We guarantee that all structural members exhibit minimum deflection under full rated capacities.
Our raw structural steel profiles are fully traceable. We source exclusively from tier-1 steel mills, matching international ASTM, EN, and GB raw material criteria.
With an established international network, we offer comprehensive customs clearance preparation and container consolidation. Our products arrive with assembly instruction layouts to guarantee quick installation by local contracting crews.
Pioneering smart technologies and environment-friendly production processes for next-generation warehousing.
Development of smart weight-sensing rollers utilizing low-power Bluetooth grids. These tracks notify control panels when replenishment is needed or if a carton is jammed along the dynamic slope.
Implementing new polymer composites for rollers to eliminate ball bearings entirely, reducing system weight, lowering rolling noise, and maintaining high roll rates at sub-zero cold storage zones.
Transitioning to zero-VOC waterborne powder coating systems and integrating solar-powered manufacturing lines to slash carbon footprint by up to 35% on structural fabrication.
Quick answers to key technical, custom, and logistical questions.
Typically, the ideal slope angle falls between 2% and 4.5% (approx. 1.2 to 2.5 degrees). However, this depends on package weight, carton composition, and the type of rollers utilized. We perform trial flow testing using client packaging samples to identify the optimal incline that ensures smooth transit without impact damage.
We source high-grade Q235B and Q345B steel directly from major Chinese steel manufacturers. Mill test certificates are acquired for each batch. Furthermore, our 35-person quality inspection team performs chemical composition testing, thickness checks, and stress-deflection tests before roll forming begins.
Roller lanes utilize full-width cylindrical steel or plastic rollers, which are ideal for heavy cartons or weak-bottomed boxes. Wheel beds (or span-track designs) utilize multiple columns of staggered polycarbonate wheels, offering higher flexibility to adjust lane spacing and accommodate varying box widths on a single shelf.
Yes. All OEM/ODM shipments are accompanied by comprehensive engineering blueprints, layout configurations, and 3D assembly guides. For large-scale integration projects (over 5,000 sqm), we can send senior installation consultants to guide local operations crews on-site.
