Heavy-duty configurations engineered for high-density FIFO cold storage and industrial warehousing needs.
The Rajshahi Division, long recognized as the agricultural powerhouse of Bangladesh, is transitioning from traditional farming practices to a sophisticated agri-industrial and logistics hub. The region dominates the country’s mango, potato, and grain production. Crucial infrastructure expansions—including upgraded highways, the Padma Bridge rail link connectivity, and the development of BSCIC Industrial Estate-II in Rajshahi—have created a critical need for modern, scalable storage solutions.
For decades, warehouses in the Rajshahi district operated on traditional static racking or floor stacking. These outdated layouts suffer from significant drawbacks: high product spoilage due to poor First-In, First-Out (FIFO) control, low space utilization, and damage to fresh produce from excessive manual handling. Food processing enterprises, seed distributors, and cold storage facilities require dynamic storage systems that maximize volume while keeping logistics operations moving efficiently.
Nanjing Ciho Racks Co., Ltd. delivers custom-engineered Pallet Flow Racking Systems tailored to Rajshahi's unique operating environment. Our systems feature gravity-driven roller lanes that utilize the warehouse's vertical space, cutting forklift travel times and keeping storage density high. Whether storing perishable fruit pulp in cold rooms or raw material pallets in dry warehouses, our gravity flow systems keep operations running smoothly, safely, and efficiently.
Also known as gravity flow racking, pallet flow racking utilizes dynamic flow lanes set at a fixed incline. The system uses gravity to automatically move pallets from the loading side (entry) to the picking side (exit). While simple in theory, building a safe, reliable system requires precise engineering calculations that take into account load weight, pallet quality, roller design, and velocity control.
The standard incline angle for gravity flow lanes is set between 3.5% and 4.0%. A shallower slope might cause pallets to stall along the lane, while a steeper slope can accelerate heavy loads too quickly, posing safety risks at the exit face. Nanjing Ciho uses variable roller gradients matched to your specific pallet profiles. Centrifugal speed controllers are integrated every 1.5 to 2 meters inside the lane to keep pallet speeds under a safe 0.3 meters per second.
Depending on pallet quality and load profiles, we offer two main roller configurations:
To protect workers at the discharge face, we install automatic pallet separators. These mechanical separators isolate the first pallet (at the picking position) from the pressure of the following pallets in the lane. This allows forklift operators to remove the front pallet without facing back pressure, minimizing damage and ensuring a safer workspace.
| System Parameter | Technical Specification | Operational Benefit |
|---|---|---|
| Load Capacity | 500 kg to 1,500 kg per pallet position | Supports heavy agricultural yields and industrial goods |
| Lane Depth | 2 to 20 pallets deep (customizable) | Maximizes warehouse volume and storage density |
| Steel Grade | High-tensile structural steel (Q235B & Q355B) | Provides high structural rigidity and seismic safety |
| Operating Temperature | -30°C to +40°C | Optimized for cold rooms and blast-freezing facilities |
| Finish Options | Electrostatic epoxy powder coat or Hot-Dip Galvanized (HDG) | Prevents rust in high-humidity or cold environments |

To maintain consistent quality, we utilize advanced production machinery and automated manufacturing processes. Below is an overview of our production line, demonstrating our commitment to quality from raw steel to finished racking components:
Every warehouse operates differently based on its industry. We customize our racking designs to meet the specific storage, sanitization, and throughput demands of Rajshahi's core sectors:
Perfect for storing potatoes, mango pulps, and frozen foods. High-density storage reduces the total footprint of cold rooms, lowering electricity consumption while keeping FIFO rotation consistent to prevent product spoilage.
Designed to support high-throughput, multi-level lines that feed raw materials directly into processing systems. Automatic speed controllers prevent pallet damage, keeping operations running safely and efficiently.
Streamlines case picking by dedicating lower racking levels to carton flow tracks, while upper levels store reserve pallets. This organization simplifies inventory management and speeds up order fulfillment.
Bangladesh falls into active seismic zones (with Rajshahi located in Seismic Zone II/III). Under the Bangladesh National Building Code (BNBC 2020), racking systems must be engineered to withstand lateral seismic forces. Nanjing Ciho designs structural frames using high-tensile steel, thick baseplates, and dual anchor bolts to ensure the racking stays stable and safe during seismic events.
Purchasing heavy industrial racking internationally requires clear communication and a reliable supply chain. By partnering with Nanjing Ciho Racks, customers in Rajshahi benefit from our direct factory supply model, structured manufacturing processes, and experienced logistics handling:
