High-Density Storage Systems for Space Optimization

Very Narrow Aisle (VNA) racking is designed to increase pallet storage density by reducing aisle widths to approximately 5-8 feet. VNA systems are intended for facilities that use turret trucks (5-6 feet aisles), articulated forklifts (5-7 feet aisles), or multi-directional forklifts (6-8 feet aisles).

VNA racking allows operations to maximize both vertical and horizontal storage capacity while maintaining full pallet selectivity.

System Design and Configuration

RACKsteel engineers VNA racking systems based on site-specific operational and structural requirements. When we design VNA systems, we consider the following:

Pallet load weights and dimensions
Required clearances for safe equipment operation
Material handling equipment specifications
Vertical lift heights and mast profiles
Seismic and structural code requirements

Beam elevations and upright configurations are optimized to maximize storage density while adhering to equipment and safety limitations.

VNA Racking Performance Characteristics

VNA racking systems provide the following operational benefits:

Full selectivity to all pallet positions
Increased storage density compared to standard aisle layouts
Reduced aisle footprint and travel distance
Controlled and repeatable equipment movement
Compatibility with automated and semi-automated systems

Systems are engineered to support high-throughput environments with large SKU counts.

Guidance and Control Systems

RACKsteel integrates guidance solutions to support safe and efficient VNA operation, including:

Floor-mounted rail (bumper-to-bumper guidance)
Magnet guidance
Wire guidance
Layout coordination for guided equipment travel paths

Guidance systems are designed to align with racking geometry and material handling equipment requirements.

Applications

VNA racking systems are commonly specified for:

Third-party logistics (3PL) operations
High-turnover distribution centers
E-commerce fulfillment
Manufacturing environments with high SKU variability

These systems are suitable for facilities seeking to maximize storage capacity within existing building footprints.

Engineering, Installation, and Compliance

RACKsteel provides complete project support for VNA racking installations, including:

Optimized solutions based on SKU throughput and size
Structural and seismic compliance review
Engineering and load calculation
In-house drafting
Professional installation by trained internal crews

All VNA systems are supplied in accordance with all applicable codes, including the Municipal and National Building Code of Canada 2025, CWB, CSA, and operational safety standards.

Request a VNA Racking Assessment

To evaluate whether VNA racking is suitable for your facility, submit a request with building dimensions, equipment specifications, and storage requirements. A RACKsteel representative will review the information and provide a technical assessment and system recommendation.
