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

June 08 01:06:50, 2025

The storage shelving unit is made up of column sheets, beams, and laminates. The primary distinction between the main frame and the sub-frame lies in the number of column sheets they contain. 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 that the sub-frame only features a single column, it needs to be used in combination with the main frame, which can stand independently. We usually refer to each row of shelves as a main rack, while the remaining sections are considered sub-frames. Beyond saving on materials like columns and reducing costs, shelving units with both main and sub-rack structures offer several benefits: 1. They are easy to install and can be quickly assembled or adjusted as needed. 2. These shelves boast strong load-bearing capabilities, making them ideal for use in large-scale warehouses. 3. They help save space, providing a tidy and efficient arrangement that enhances operational efficiency. 4. The shelves are modular, allowing for easy assembly and disassembly, while also maintaining an elegant appearance that ensures safety and reliability. 5. The column and pillar designs are carefully engineered based on mechanical principles and formed through roll molding, offering excellent value for money. 6. All shelf components undergo surface treatments such as rust removal, degreasing, pickling, phosphating, and spraying, ensuring durability and longevity. In practical applications, this design not only optimizes resource utilization but also ensures that the shelving system remains robust and adaptable to various storage requirements. This combination of functionality and cost-effectiveness makes these shelves particularly appealing for modern warehouse management.
