The Difference between VNA Racking and Pallet Racking

In daily warehouse operations, the coordinated use of pallets and racks, often complemented by equipment such as forklifts, forms a systematic warehouse rack operation. Among the various types of storage racks, standard pallet racks are commonly used in typical warehouses. They are considered as beam-type racks or heavy-duty racks, given their relatively modest size compared to high-rise racks. How do they compare to Very Narrow Aisle (VNA) racks, and what are their similarities and differences?

Let's first delve into the characteristics of Very Narrow Aisle (VNA) racks. Also known as heavy-duty narrow aisle racks, they are essentially a variation of beam-type racks, resulting from specific improvements and targeted design modifications. While they share some similarities with standard heavy-duty pallet racks, there are notable differences.

Similarities between Pallet Racks (Beam-type Racks) and Very Narrow Aisle (VNA) Racks:

1. Basic Structure: Both types of racks have a similar basic structure. VNA racks are essentially a reimagined version of traditional beam-type racks, incorporating their fundamental structure and characteristics.

2. Forklift Operation: Both standard pallet racks and VNA racks typically utilize forklifts for operations, and the layout of each pallet position in both types of racks is generally similar.

3. Load Configuration: The selection of pallets for loading in both types of racks is based on similar considerations, taking into account the attributes and stacking requirements of the goods.

4. Heavy-Duty Application: As heavy-duty racks, both are designed for the storage of industrial goods, requiring skilled forklift operators and warehouse management personnel.

Differences between Traditional Pallet Racks and Very Narrow Aisle (VNA) Racks:

1. Storage Level and Operation: Standard pallet racks are low-level storage racks, often operated by standard forklifts or manual labor. In contrast, VNA racks are high-rise racks, typically requiring specialized forklifts for operation.

2. Number of Levels: While heavy-duty racks typically have 3-5 levels, VNA racks are much taller, reaching 10 meters or more. This allows for more dense storage of goods.

3. Aisle Width: VNA racks have narrow aisle widths, as the name suggests, facilitating efficient space utilization. In contrast, standard heavy-duty pallet racks allow for wider aisles to accommodate standard forklift turning widths.

4. Structural Configuration: VNA racks are visually characterized by two parallel beam-type racks connected together. Standard heavy-duty pallet racks are usually standalone units, and at most, the main and secondary racks can be separated and reconfigured.

In summary, while pallet racks and VNA racks share some structural similarities, they each have distinct storage characteristics. Customers might need to consider their warehouse attributes and equipment configurations to determine the most suitable storage rack.
