How to distinguish the quality of the stacking rack

1. Material of stacking frame: It seems that there is no set of strict and complete industry standards in China.

2. Its surface treatment: The surface spraying treatment should be uniform and strong adhesion. Whether the surface spraying of the shelf is even depends on whether there are omissions on the inner edge of the shelf column hole. Easily fall off indicates that it is easy to rust.

3. Its structure: the column depends on whether the cross section is bent more and evenly, and the structure should be more or less uniform and symmetrical, the better. The crossbeam depends on the hook structure of the crossbeam and the form of the crossbeam hanging to the column: the more hooks of the crossbeam are better, the more the force is to be agreed; the hook of the crossbeam hangs on the column depends on whether the contact between the hook and the column is close and consistent. The inner side of the column must be close to the side of the column without a gap so that the structure is stable and durable.

4. Its welding process: This is one item that is relatively easy to identify.
