Optimal Height Utilization
VNA systems utilize vertical warehouse height up to 17 meters, utilizing special turret trucks or articulated forklifts guided by floor rails or inductive wire systems.
Up to 40% Space Savings
Reduces aisle width to 1.5m–1.8m, maximizing overall storage cubic meter capacity.
100% Pallet Accessibility
Combines maximum storage density with immediate, direct access to every single SKU.
DIN EN 15512 Certified
Structural calculations and design built strictly according to European engineering codes.
Engineered Storage Solutions
High-Density Storage with 100% Direct Selective Access
Very Narrow Aisle (VNA) racking systems manufactured by StahlRack Intralogistics GmbH are designed for industrial logistics facilities where floor space is premium and high SKU selectivity is mandatory. By reducing operating aisles down to 1.5–1.8 meters, VNA racking increases floor space utilization by up to 40% compared to standard adjustable pallet racking.
Lower Cost per Pallet Position
By dramatically increasing floor density without sacrificing individual pallet access, total infrastructure and operational costs per pallet position are significantly lowered.
Enhanced Safety & Guidance
Integrated mechanical guide rails or wire-guidance paths prevent forklift collisions with racking uprights, safeguarding inventory and reducing maintenance overhead.

System Components
Key Structural Components of StahlRack VNA Racking
Every VNA racking system manufactured by StahlRack Intralogistics GmbH utilizes certified high-grade structural steel and specialized protection accessories engineered for heavy industrial duty.
1Precision Upright Frames
Cold-rolled profile uprights with 50mm adjustability pitches, designed with high structural rigidity to meet tight deflection limits under heavy loads at height.
2Heavy-Duty Box Beams & Connectors
Interlocking structural box beams equipped with multi-claw safety connectors and safety pins to prevent accidental disposition during high-reach operations.
3Integrated Truck Guide Rails
Heavy steel angle floor-guided rails anchored into the concrete floor slab to lead VNA turret trucks smoothly and safely down long aisles.

Technical FAQ
Frequently Asked VNA Questions
Key information for warehouse directors, industrial engineers, and procurement teams planning a Very Narrow Aisle installation.
Need a VNA Layout Proposal?
Send us your warehouse CAD drawing or pallet specifications for a free calculation.
VNA operating aisles typically range from 1,500 mm to 1,800 mm, depending on the chosen turret truck, VNA forklift, or articulated truck model. This compares to 3,000 mm–3,500 mm required for standard reach trucks.
We supply floor-anchored steel angle guide rails (mechanical guidance) or design the system layout to integrate with in-floor inductive wire guidance lines, ensuring precise and safe truck travel down long aisles.
Due to elevated storage heights (up to 17 meters), floor slab flatness and levelness must meet DIN 18202 or VDMA / FEM 9.831 standards to prevent mast sway and ensure operational safety.
Yes. StahlRack VNA systems are routinely configured for EPAL Euro pallets (1200 x 800 mm), industrial pallets (1200 x 1000 mm), or custom non-standard load dimensions.
Standard manufacturing timelines range from 15 to 25 days depending on total tonnage. Full delivery and installation schedules are provided upon final approval of CAD drawings.
