Explore our highly customized, heavy-duty narrow aisle storage configurations engineered to maximize space utility in high-cost land corridors.
Turkey has firmly established itself as a critical bridge between Europe, Asia, and the Middle East. With major industrial zones situated in the Marmara region (Istanbul, Kocaeli, Bursa), the Aegean corridor (Izmir), and central hubs like Ankara, industrial land prices have skyrocketed. Supply chain organizations are forced to seek methods to maximize volumetric storage efficiency within existing structural footprints.
Conventional pallet racking systems require aisle widths ranging between 3.2 and 4.2 meters. In contrast, Very Narrow Aisle (VNA) racking systems restrict aisle widths down to just 1.5 to 1.8 meters. This structural migration allows distribution centers to reclaim up to 50% of wasted aisle floor space, turning it into dynamic storage area, whilst retaining 100% individual pallet selectivity.
A technical layout analysis demonstrates how VNA transforms warehouse floor efficiency compared to traditional Selective pallet racking systems.
| Metric Indicator | Selective Racking | VNA System |
|---|---|---|
| Aisle Width Required | 3.5m - 4.0m | 1.5m - 1.8m |
| Storage Floor Yield | Approx. 35-40% | Approx. 60-65% |
| Maximum Height | Up to 8-10m | Up to 15-18m |
| Pallet Access Rate | 100% Immediate | 100% Immediate |
| Forklift Systems | Reach / Counterbalance | Turret Truck / AGV |
Global expertise meeting localized structural demands. We provide industrial-grade warehouse systems configured to survive tough heavy-duty applications.
Nanjing Ciho Racks Co., Ltd. is a leading manufacturer specializing in industrial warehouse storage solutions. Leveraging advanced manufacturing capabilities and structural design software, our systems are engineered to optimize floor layouts and improve logistics flow on a global scale.
Our extensive product line includes selective pallet racks, drive-in systems, cantilever racks, mezzanine structural platforms, longspan shelving, and highly advanced automated VNA storage structures. From initial project evaluation and FEA (Finite Element Analysis) structural simulation to cold-roll forming, automated welding, and powder coating, we handle the entire workflow to guarantee performance safety.
Partnering with engineering design offices globally and serving specialized supply chains across Turkey and EMEA markets, we ensure our structures accommodate customized material handling equipment, such as wire-guided turret trucks or autonomous mobile robots (AMRs).

VNA Racking requires precise engineering to maintain stability under high loads at extreme vertical reaches. Below are the core technical design properties we apply.
| System Attribute | Technical Design Standard & Spec | Practical Advantage for Operations |
|---|---|---|
| Seismic Compliance | TS EN 15512, Eurocode 3, AFAD Seismic Guidelines | Prevents buckling under harmonic oscillation during seismic activity. |
| Vertical Deviation Limit | H/1000 max deviation under full-load condition | Crucial for high-lift turret forklifts to prevent mast-to-beam collision. |
| Safety Factor | 1.5 minimum yield safety multiplier | Protects integrity against accidental load drops or dynamic overloading. |
| Guide Rail Profiles | Steel guide rails (100mm x 50mm C-channel) or electromagnetic wire tracking | Restricts horizontal truck travel variance, preventing upright scraping. |
| Finish Coating | Electrostatic powder coating (thickness > 80 microns) or Hot-Dip Galvanizing | Resists mechanical abrasion, dampness, and chemical exposure. |
Operating at heights exceeding 10 meters within narrow aisles requires precise synchronization between the racking structure and the materials handling machinery. Our VNA racking frames are built with custom tolerances to accommodate Man-up and Man-down Turret Trucks, as well as state-of-the-art Automated Guided Vehicles (AGVs). Floor leveling parameters and guide rail straightness are validated using optical laser measurement instruments during final commissioning.

From shipping to major ports to site coordination, we streamline custom import channels.
Direct ocean freight shipping to primary Turkish maritime gateways including Ambarli Port (Istanbul), Gebze/Yilport, Izmir (Alsancak/Aliaga), and Mersin. We manage packing to maximize container utilization and eliminate transit damage.
We provide comprehensive technical documentation, raw material mill certs, and structural calculations to assist your engineers in passing municipal site safety inspects within local Turkish free zones (OSB).
Detailed CAD drawings, assembly manuals, and direct remote engineering guidance. We collaborate with local Turkish assembly crews to ensure guide rails, anchor bolts, and frame tolerances conform strictly to standard limits.
Expert technical answers addressing design requirements, forklift interfaces, and local structural compliance.
Our VNA racking systems can be designed to reach structural heights up to 18 meters. The maximum limit is governed by the structural load ratings of your warehouse floor slab, local seismic zone parameters, and the maximum lift capabilities of your turret truck or automated stacker crane.
Every VNA system engineered for Turkey undergoes strict finite element analysis (FEA) based on the Turkish Building Earthquake Code (TBDY 2018) and European standards (EN 15512). We adapt frame profiles, thickness, and base plate dimensions depending on the specific seismic ground acceleration values of your site.
Steel guide rails are highly durable physical barriers that actively protect the upright structures from accidental impact. Inductive wire-guided systems eliminate physical floor rails, allowing easier cleaning and reducing localized debris buildup, but require precision floor excavation and specialized forklift sensors.
We strictly manufacture using certified Q235B and Q345B high-tensile structural steel. Our standard finish is an automated electrostatic powder coat, cured at high temperatures to offer maximum impact and scratch resistance. For cold-chain environments, we provide hot-dip galvanized components.
Production lead times generally range between 20 to 30 days depending on project size and degree of customization. Ocean transit from China ports to major Turkish destinations (such as Ambarli, Gebze, or Izmir) takes approximately 25 to 35 days, resulting in a total timeline of 8 to 10 weeks from deposit to port delivery.
Whether you are engineering a new distribution center in Kocaeli or optimizing an existing retail storage facility in Izmir, our structural engineers are here to assist with layouts, load calculations, and competitive pricing.
