Warehouse space is expensive — and in many cases, underutilized due to wide aisles.
The VNA (Very Narrow Aisle) system is one of the most effective ways to maximize storage density.
Aisle Width Comparison
- Standard pallet racking: 3.2–3.5 meters
- VNA racking: 1.5–1.8 meters
This reduction can save nearly 50% of aisle space, significantly increasing storage capacity.
Key Benefits of VNA
- Storage capacity increased by 30–50%
- Warehouse height utilization up to 12–15m+
- Improved operational efficiency
Critical Design Requirements
1. Floor Flatness
VNA systems require high floor precision (FF/FL standards).
2. Guidance System
- guide rails or magnetic guidance
- Ensures precise forklift movement
3. Installation Accuracy
- Millimeter-level precision is required
Shitong Racking Capabilities
- Integrated racking + rail system design
- Warehouse layout optimization
- Coordination with VNA forklift suppliers
VNA is not just a product — it’s a complete system solution.
