The aisle width in warehouse design is one important factor in order to maximize storage capacity. Compared to standard pallet rack, very narrow aisle racking system has made some adjustments by placing more racks closer. The storage capacity has increased while the opration convenience may be interfered.

Features of very narrow aisle pallet racks
1. Mostly, very narrow aisle racking systems are designed with high bay for fully vertical space utilizaiton.
2. The initial investment for VNA is relatively large with high quality steel and special VNA forklifts for material handling.
3. The whole working difficulty has risen since forklifts have to work in narrower aisles dealing with higher bays.
4. The VNA aisle width is about 8’ to 10’, while aisle width of standard pallet racking systems is commonly ranged from 12’ to 14’.
5. 100% selectivity and full accessibility just like conventional selective pallet racks since the basic configuration remains same.
6. Obeying First-in/First-out (FIFO) stock rotation, VNA system is suitable for fast turn-over items.
7. VNA systems can function as the basic storage units for ASRS system and can also be compacted with other storage solutions in large distribution centers.
Components for VNA racking system
Upright frames
⇒ consisting of two columns and several horizontal and diagonal bracings
⇒ powder-coated, galvanized or mixing of the two for surface treatment
⇒ several row-spacers are necessary for adjacent two frames to increase structure stability
⇒ expanded baseplates are optional for particular high rack structure or in seismic zone

Guide rails
Guide rails are important safety accessory that differs from traditional pallet rack. The higher structure has blocked some of the field of vision from forklift operators so the installation of guide rails will facilitate the safe and efficient material handling.
Lacking enough space for commodities storage may become a block that may slow down your business growth. Creating extra space for more pallets, high-density very narrow aisle pallet racks offer you an alternative that is more economical compared to building a new warehouse.
At the same time, the warehouse workflow and productivity are preserved thanks to constantly updated VNA forklifts. If you are not sure if VNA pallet racking is the right choice for your facility, you can always turn to Ironstone professional rack engineers for consultancy.
