Browse our industry-leading range of heavy-duty industrial shelving, retail display racking, and high-density warehouse storage systems engineered to optimize space and streamline workflows.
The global warehousing landscape is undergoing an unprecedented shift. Driven by skyrocketing real estate prices, complex multi-channel e-commerce models, and strict labor management paradigms, traditional storage structures are hitting physical limitations. Modern warehouse operators are moving away from passive static storage racks toward dynamic systems like Flow Racking, which combine gravity-driven transport with smart space management.
By leveraging dynamic physics, flow rack systems—both pallet flow and carton flow—create an automatic stock rotation model operating under First-In, First-Out (FIFO) principles. This eliminates redundant forklift travel, optimizes space utilization up to 60% compared to standard selective racking, and reduces energy consumption in cold chain operations.
For multinational purchasing directors and supply chain engineers, selecting a reliable flow rack systems supplier is no longer a simple transactional purchase. It is a strategic infrastructure investment that directly impacts operational throughput, warehouse safety metrics, and return on investment (ROI).
Nanjing Ciho Racks Co., Ltd. is a specialized global designer, manufacturer, and supplier of heavy-duty industrial racking and smart storage systems. Armed with deep engineering capabilities and years of structural design experience, we specialize in high-capacity pallet flow racks, gravity-driven carton flow racks, and highly integrated multi-tier mezzanine layouts.
Headquartered in Nanjing, China’s industrial steel fabrication hub, Ciho Racks leverages high-grade raw steel (such as Q235B and Q355B), state-of-the-art automated roll-forming machines, and advanced robotic welding lines. This ensures every rack, beam, upright frame, and dynamic flow bed conforms to international safety standards, including the RMI, FEM 10.2.02, and AS4084 specifications.
We perform rigorous FEA (Finite Element Analysis) to simulate seismic loads, wind pressures, and structural stresses, ensuring long-term reliability under heavy industrial conditions.
From CAD layout design and pitch adjustments to dynamic roller selection, our engineers work alongside your operation team to customize the system to your specifications.
Our automated powder-coating lines apply a heavy-duty, impact-resistant epoxy-polyester powder layer. This prevents rust, scratches, and chemical degradation in humid and sub-zero environments.
Quality and precision are the bedrocks of Nanjing Ciho Racks Co., Ltd. Below is a detailed view of our automated manufacturing process, from raw steel sheet inspection to custom robot welding, precise bending, and final shipping preparation.
Dynamic flow rack systems rely on basic physics to move inventory along inclined roller lanes. While simple in concept, the engineering details determine whether a system will operate smoothly or cause inventory blockages, safety hazards, and accelerated wear. When designing an industrial system, we evaluate three primary technical criteria:
Pallet Flow (Gravity Flow) Racks: Designed for heavy, palletized loads (typically 500kg to 1,500kg per pallet). These setups feature heavy-duty steel channels and inline roller beds with dynamic speed controllers. As a pallet is loaded at the charge end, gravity drives it toward the pick face. Dynamic brake rollers prevent runaway pallets by keeping speeds below 0.3 meters per second.
Carton Flow Systems: Ideal for high-density carton pick modules and split-case picking. These utilize lightweight aluminum or plastic skate wheels arranged in customized flow beds. These tracks are often integrated directly into selective pallet racks or multi-tier pick towers to simplify fast-moving SKU fulfillment.
The incline of a flow lane is a critical variable. An angle that is too steep will cause impact damage at the pick face, while a shallow angle can cause stalls. Our engineering team calculates the ideal pitch—typically between 3% and 4.5%—based on specific product characteristics, packaging materials, and environmental factors like humidity and cold-room temperatures.
| Parameter | Carton Flow Systems | Pallet Flow Systems |
|---|---|---|
| Load Range | 5 - 50 kg / box | 300 - 1500 kg / pallet |
| Incline Rate | 3.0% - 5.0% | 3.5% - 4.2% |
| Roller Types | PP, PE, Alu Skate Wheel | Galvanized Steel Rollers |
| Braking Mechanism | Manual Entry Guides | Centrifugal Speed Controllers |
| Standard Material | Q235B / Cold Rolled | Q355B High Tensile Steel |
Different industries require unique flow rack configurations to meet their specific storage and operational demands. We tailor our engineering designs to match the requirements of several key sectors:
In cold storage environments where operating costs are high, space utilization is critical. Our low-temperature grease-lubricated steel bearings operate reliably down to -30°C without seizing. The high-density storage layout reduces the overall air volume that requires refrigeration, lowering energy overheads.
To support high-velocity piece picking, our carton flow tracks integrate pick-to-light systems and barcode scanning arrays. This layout separates loading operators from pickers, minimizing traffic conflicts and picking errors.
In just-in-time (JIT) production lines, components must feed assembly stations without interruption. Heavy-duty custom flow tracks handle heavy containers, automotive components, and metal bins, keeping operations moving smoothly.
The rise of automated material handling is transforming traditional gravity flow installations. Nanjing Ciho Racks Co., Ltd. is actively designing systems that bridge the gap between mechanical gravity layouts and automated logistics:
Deploying storage infrastructure requires strict adherence to local building codes, fire safety rules, and structural guidelines. As an experienced exporter, Nanjing Ciho Racks Co., Ltd. ensures all deliveries comply with local structural requirements:
