What is the difference between the main rack and the secondary rack of the storage shelf

June 08 01:10:57, 2025

The storage shelving system comprises column sheets, beams, and laminates. The primary distinction between the main frame and the sub-frame lies in their structural components, particularly the number of column sheets. A main frame typically includes two column sheets along with multiple layers of beams and laminates, whereas a sub-frame consists of just one column sheet. Given its single-column design, the sub-frame cannot function independently and must always be paired with a main frame, which can stand alone. We commonly refer to the collection of shelves in each row as the main rack, while the remaining sections are termed sub-frames. Beyond reducing material usage and cutting costs, this main-sub frame structure offers several additional benefits: 1. **Ease of Installation**: These shelves are designed for flexibility, allowing users to quickly assemble them at will and adjust heights effortlessly. 2. **Robust Load Capacity**: Their sturdy construction makes them ideal for heavy-duty use in large-scale warehouses. 3. **Space Efficiency**: The organized layout ensures optimal space utilization, making operations more efficient and enhancing overall warehouse aesthetics. 4. **Durability and Safety**: Assembled with precision and using high-quality materials, these shelves are both visually appealing and structurally sound. 5. **Cost-Effective Design**: The columns and beams are engineered based on mechanical principles, ensuring durability without compromising affordability. 6. **Longevity**: Each component undergoes rigorous surface treatments like rust removal, degreasing, pickling, phosphating, and spraying, guaranteeing extended service life. This shelving system not only meets practical needs but also reflects thoughtful engineering, making it an excellent choice for modern warehouse management.
