Why can roll forming of aluminum profiles and aluminum plates improve the load-bearing performance of RC-H Heavy Duty Aluminum Storage Box?

The RC-H heavy-duty aluminum storage box uses aluminum profiles as the main frame structure. The advantage is that the profiles are usually designed as hollow or multi-cavity forms, which can significantly improve the overall bending and compression resistance through geometric shapes (such as ribs or honeycomb structures) while ensuring lightweight. This structural design enables the box to more evenly distribute the load when bearing heavy objects, avoiding local stress concentration, thereby greatly improving the overall load-bearing performance. In addition, the standardized production of aluminum profiles ensures accurate box dimensions and more stable structures when spliced, further enhancing durability.

The roll forming process gradually cold-presses the aluminum plate into a specific shape through multiple rollers, so that the plate forms a rib structure, thereby greatly improving the rigidity of the box. Compared with traditional welding processes, roll forming can reduce the number of welds, avoid stress weak points in the welding parts, and make the box more sturdy and durable. At the same time, the process can accurately control the thickness and shape of the plate, increase the material strength at key stress-bearing parts (such as edges and joints), avoid redundant weight, and achieve a balance between lightweight and high load-bearing.

Aluminum alloy has an excellent strength-to-weight ratio. Under the same load-bearing requirements, aluminum boxes are lighter than steel boxes, making them easier to carry and stack. In addition, the oxide film naturally formed on the surface of aluminum alloy gives it excellent corrosion resistance. Even if it is used for a long time in moisture, salt spray or harsh outdoor environments, it will not reduce its load-bearing capacity due to rust. This feature makes the RC-H storage box particularly suitable for harsh application scenarios such as industry, military, and marine transportation.

The rigid structure of the box is rolled and formed, combined with aluminum cast corner guards, which further enhances the load-bearing capacity during stacking. The corner guards are located at the four corners of the box, directly bearing the pressure of the upper box, and evenly distributing the load through the overall structure of the box to avoid local deformation or collapse. This design not only increases the load-bearing limit of a single-layer box, but also ensures the stability of multi-layer stacking, allowing the RC-H storage box to safely carry heavy items during storage and transportation.
