A trusted global partner specializing in heavy-duty warehouse storage designs and advanced racking engineering.
Nanjing Ciho Racks Co., Ltd. is a leading professional manufacturer and exporter in China, specializing in heavy-duty warehouse storage systems and smart industrial racking solutions. Leveraging state-of-the-art cold-rolled steel manufacturing technology, we provide global logistics systems with the critical hardware needed to scale efficiently.
Our expansive product portfolio spans selective pallet racks, drive-in racks, structural cantilever racks, custom mezzanine structures, highly versatile longspan shelving, steel mezzanine platforms, heavy-duty carton flow tracks, and bespoke storage structures. Engineered strictly to maximize overhead density while protecting human safety, our systems are widely utilized by top-tier global distribution centers, e-commerce giants, high-output manufacturing lines, cold chain warehouses, and high-density archive centers.
Underpinned by rigorous compliance and engineering safety protocols, our QA process manages every detail from steel alloy inspections to structural load verification. Backed by a responsive international support team, we deliver high-performance racking on budget, on time, and certified to meet regional building codes worldwide.
Manufactured from high-grade Q235B and Q355B structural carbon steel to withstand extreme environments.
FEA-backed calculation reports ensuring alignment with FEM, RMI, and AS4084 regulations.
Tested strictly for static and dynamic load capacity, seismic stability, and impact tolerance.
Reliable logistics and packing protocols servicing Europe, North America, Middle East, and APAC.
Understanding the critical trends shifting spatial storage requirements to multi-tier longspan configurations.
Across the globe, rapid e-commerce expansion, rising industrial land costs, and SKU multiplication are forcing logistics managers to rethink traditional warehouse plans. To control overhead, modern warehouses must convert wasted vertical height into active inventory zones. Here, Industrial Longspan Racking serves as an essential link between small carton shelving and heavy industrial pallet racks.
For hand-loaded goods, small components, and mid-sized cargo (e.g., automotive spares, online retail apparel, boxed electronics), longspan racks offer the perfect configuration of high load capability and structural versatility. Optimized for quick access, they are highly compatible with warehouse management systems (WMS), carton flow modules, and automated vertical picking tools.

| System Component | Material Class / Grade | Dimension & Depth Options | Structural Load Rating |
|---|---|---|---|
| Upright Frames | Q235B / Q355B Steel (Cold-Rolled) | Widths: 50 | 55 | 60 mm; Thickness: 1.5 - 2.0 mm | Up to 4,500 kg per bay |
| Z-Beams / Step Beams | High-Tensile Cold-Rolled Carbon Steel | Profiles: P50 | P60 | P80; Length: 1000 - 2700 mm | 300 - 1,000 kg per level (UDL) |
| Shelf Inserts | Galvanized Steel / MDF Panel / Wire Mesh | Thickness: 0.6 - 1.2 mm (Steel); 15 - 18 mm (MDF) | Supports matching beam capacity |
| Hardware & Anchors | Class 8.8 High-Tensile Zinc Plated Fasteners | M8/M10 Expansion Anchors & Safety Pins | Seismic-resistant rating |
We run finite element analysis (FEA) to simulate load configurations, deflection ratios, and seismic activity. This ensures our designs maintain a structural safety factor of 1.5+ under full load.
Our advanced electrostatic powder coating protects profiles from scratches and chemical exposure. Pre-galvanized options are also available for cold-room and outdoor storage applications.
Every warehouse layout is unique. Our CAD design team tailors frames, shelves, and upright heights to balance storage density, ceiling height, and floor space perfectly.
Combining raw material access, advanced robotic production lines, and strict quality control.
Nanjing is the epicenter of the global steel racking industry. By centering our manufacturing here, we integrate several key advantages:
At Nanjing Ciho Racks, we enforce a strict quality control loop. We verify every production run against three core standards:
Adapting physical racking configurations to meet regional codes and specific industry operational flows.
Designed for high-density carton pick tunnels, combining steel levels with mesh shelves. Includes labels and safety barriers for fast, manual cart picking.
Features deep shelf dimensions (up to 1200mm) and adjustable dividers to store heavy exhaust pipes, brake rotors, and gearboxes safely.
Heavy-duty layouts optimized for file boxes. The flame-resistant steel design complies with strict national fire code regulations.
Ensuring structural reliability that stands up to international engineering audits.
Our systems meet major global racking structural design standards, including AS4084-2012 (Australia), FEM 10.2.02 (Europe), and RMI Guidelines (United States). This design compliance ensures fast local permitting and structural engineering approval.
We provide full technical documentation, detailed structural drawings, and installation guides. For large-scale projects, we offer virtual video support and can send field engineers to help manage setup safely.

Longspan shelving is designed for manually loaded, light-to-medium-weight hand-picked items (typically ranging between 300kg and 1,000kg per level). Pallet racking is designed to hold heavy, palletized loads loaded by forklifts (often reaching 1,000kg to 4,000kg per level). Longspan frames are lighter, easier to configure, and can use steel, wire mesh, or wood/MDF decking.
We use Q235B and Q355B structural steel alloys. Q355B has a higher yield strength, which allows us to design slimmer profiles that support heavier weights without bending. All materials undergo tensile and elongation testing to ensure they perform reliably under load.
Yes. If your facility is located in a high-seismic zone, we customize the upright profiles, widen the footplates, and increase floor anchor points. Our structural team calculates these designs using seismic simulation software to ensure they meet local building safety requirements.
We offer three main decking types: powder-coated or galvanized steel shelves (for durability and fire protection), wire mesh decking (to improve water flow from overhead sprinklers and airflow), and heavy-duty MDF panels (a cost-effective choice for dry, climate-controlled environments).
Standard orders are manufactured and ready for export within 15 to 25 days, depending on the volume. Custom projects that require engineering validation or custom-sized tooling may require an additional 5 to 10 days.
