Maximize volumetric capacity with our engineering-certified Very Narrow Aisle (VNA) and heavy-duty industrial shelving setups.
Nanjing Lush Rack Co., Ltd. is a professional manufacturer specializing in industrial storage racking systems and warehouse storage solutions. The company is dedicated to the research, design, production, and installation of a full range of warehouse racks and shelving systems, providing efficient and reliable storage infrastructure for modern logistics and supply chain operations.
With strong engineering capabilities and advanced manufacturing equipment, Nanjing Lush Rack Co., Ltd. is able to deliver complete warehouse racking solutions from concept design and structural calculation to production, quality inspection, and installation guidance. Our engineering team works closely with clients to analyze warehouse space utilization, material flow, and load requirements, ensuring that each solution is safe, stable, and cost-effective.
In the landscape of modern supply chains, the cost of warehousing real estate requires optimum volumetric density. Traditional selective pallet racking systems require aisle widths ranging between 3.5 to 4.5 meters to accommodate standard counterbalance forklifts. This layout sacrifices up to 40% of horizontal surface area purely for vehicular maneuvering.
Very Narrow Aisle (VNA) racking systems solve this inefficiency by reducing operating aisles to between 1.5 and 1.8 meters. By shrinking the aisle footprint, VNA racking systems free up critical floor space, enabling companies to increase storage capacity by up to 60% without expanding the physical footprint of their facility. Operating at heights up to 15 meters, VNA racking relies on dedicated materials handling equipment (MHE) such as wire-guided or rail-guided 3-way selective turret trucks or man-up order pickers. This allows safe, rapid access to every pallet position while maintaining selective accessibility.
A comparative engineering breakdown highlighting why structural rigidity and steel grades dictate system safety in high-bay applications.
| Racking Feature / Metric | Standard Selective Racking | Double-Deep Racking | Very Narrow Aisle (VNA) Racking |
|---|---|---|---|
| Typical Aisle Width | 3.2m – 4.5m | 2.8m – 3.2m | 1.5m – 1.8m |
| Cubic Space Utilization | ~40% - 45% | ~50% - 55% | ~60% - 65% |
| Pallet Selectivity | 100% (Immediate Access) | 50% (Last-in, First-out) | 100% (Immediate Access) |
| Guidance Systems Required | None | Optional (Camera Assist) | Yes (Wire / Mechanical Guide Rails) |
| Maximum Height Potential | Up to 8-10m | Up to 10m | Up to 15m+ |
| Steel Grade Preference | Q235B Carbon Steel | Q235B / Q355B | Q355B High-Strength Structural Steel |
We build our upright structures using high-tensile Q355B steel, ensuring minimum yield strength to resist buckling stresses. With columns reaching up to 15 meters, the vertical tolerance must withstand static loads and dynamic operational stresses.
To eliminate collision risks in narrow channels, our systems integrate seamlessly with both mechanical steel guide rails and electromagnetic wire guidance systems. This enables high-speed travel and safe retrieval cycles.
VNA systems are highly suited for cold storage environments. By compressing the cubic space required for aisles, the system minimizes the volume of air that requires active cooling, reducing energy consumption and operational costs.
Inside the Nanjing Lush Rack production facility: How raw steel is engineered into structurally certified warehouse components.
The durability of a warehouse racking system depends on its manufacturing quality. From cold rolling to robotic welding and electrostatic powder coating, Nanjing Lush Rack employs advanced production machinery to guarantee structural integrity and precise tolerance levels across all systems.
The company maintains a strict quality control system throughout the production process, from raw material selection to final product inspection. All racking systems are designed and manufactured to meet international safety and durability standards, ensuring long service life and reliable performance even under heavy industrial use.
Nanjing Lush Rack Co., Ltd. has a skilled technical team and an experienced sales department that provides responsive communication and professional support. With stable production capacity and efficient supply chain management, we are capable of handling both standard orders and large-scale customized projects with consistent quality and on-time delivery.
Ensuring safety and reliability across global logistics centers through certified designs and calculated engineering models.
For installations in active seismic zones, standard structural formulas are insufficient. At Nanjing Lush Rack, our engineering team uses Finite Element Method (FEM) analysis software to simulate seismic loads and dynamic structural behaviors. This structural assessment informs base plate dimensioning, frame bracing configurations, and upright profile choices, ensuring compliance with local codes (such as RMI in the US and EN 15512 in Europe).
Properly engineered diagonal and horizontal bracing profiles dissipate kinetic energy, safeguarding personnel and keeping stored assets secure during seismic events.
Very Narrow Aisle racking projects require high precision in floor levelness. Standard industrial concrete slabs often have surface variations that, while negligible for typical forklifts, can cause noticeable sway at high mast reaches (12 to 15 meters).
Nanjing Lush Rack coordinates with site planners to ensure alignment with TR34 (FM1/FM2 specifications) or DIN 18202 tolerances. We also offer mechanical adjustments in our footplate assemblies to accommodate minor floor variations.
Our products are widely used in industries such as logistics and distribution, e-commerce fulfillment centers, manufacturing, automotive parts storage, cold chain logistics, and retail warehousing. We have established a strong customer base across domestic markets in China, and our products are also exported to Southeast Asia, Europe, North America, and other international regions.
As a trusted partner in warehouse storage solutions, Nanjing Lush Rack Co., Ltd. is committed to delivering high-quality racking systems, innovative storage concepts, and long-term value for our customers. We continue to focus on improving warehouse efficiency, reducing operational costs, and supporting the development of modern intelligent logistics systems.
We provide comprehensive consulting services including 3D AutoCAD design, structural load capacity calculations, and material flow optimization layout configurations at no extra cost to our B2B procurement partners.
