Very Narrow Aisle (VNA) flooring is engineered for facilities where MHE operates in narrow, defined aisles while stacking material at heights of 12 to 13 metres. At these lift heights, even small floor irregularities are magnified, making precise flatness and levelness essential for safe, efficient operation.
International Compliance
- • TR34 4th Edition Code
- • ASTM E 1155 Levelness
- • DIN 18202 Precision
- • EN 10025-2 Duraplate
Key Benefits
- Best-suited flooring solution for ASRS (Automated Storage & Retrieval Systems)
- Aisle space engineered with no joints, enabling maximum rack utilisation
- Precise flatness and levelness for stable high-lift operation
- Reduced risk of equipment strain and product damage at height
Target Facilities
- Very narrow aisle (VNA) warehousing
- High-bay racking facilities
- Automated Storage & Retrieval Systems (ASRS)
- Cold storage and logistics hubs with high-density racking
