Pallet racking is the most fundamental and widely used heavy-duty mechanized storage system in modern logistics and warehousing.
Designed specifically for storing goods on standard pallets, the system utilizes forklifts for loading and unloading operations; it maximizes vertical warehouse space, significantly enhancing both space utilization and material turnover efficiency.
Core System Type – Selective Pallet Racks:
Features: The most basic and versatile type of racking. Each pallet load faces the aisle directly, allowing forklifts 100% free access to select any pallet without the need to move other goods.
Applications: Suitable for warehouses with a large number of SKUs, low inventory levels per item, and a requirement for frequent, random access.

Regarding structural connections and hole patterns, the shape of the holes on the uprights of pallet racking determines system compatibility.
Common hole patterns found in North American and international markets include:
Teardrop Style: Currently the most popular and widely used hole pattern globally. The beam connectors are tapered; they slide into the teardrop-shaped holes on the uprights and lock automatically without the need for bolts.
This style offers a high degree of interchangeability between different brands.
Structural Bolt-In: Beams are secured directly to uprights using high-strength bolts. This design offers superior impact resistance and higher load-bearing capacities, making it ideal for heavy-duty applications in harsh environments where frequent forklift impacts occur.
Proprietary Hole Patterns: These are patented designs specific to individual manufacturers; beams and uprights must be purchased as a matched set, and components are not interchangeable between brands.
