There are many manufacturers of storage shelf racks. Many customers may not be able to understand how to control the quality of products in the inspection and acceptance process. Today, We will lead you to understand the difference between the quality of the shelf racks and the craftsmanship.

1. Regarding the choice of steel, you must choose a big factory!

The materials of storage shelf racks are generally cold-rolled steel profiles, preferably national standard, but few manufacturers use national standard (mainly price issues), the easiest way is to carry out an experiment according to the agreed load of both parties. The material of the shelf rack in China should be SS400 steel from Baogang's original factory and Shanghai Steel No. 1 Factory. There seems to be no set of strict and complete shelf rack industry standards in China, and there seem to be few shelf racks that can meet the European FEM shelf rack standards.

2. The structure of the shelf rack

The structure of the storage shelf rack, the shelf rack column depends on whether the cross-section is bent more and evenly, and the shelf rack is about a uniform and symmetric structure, the better. The crossbeam of the rack 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 , The inner side of the hook must be close to the side of the column with no gap so that the structure can be stable and durable.

3. Shelf rack beam welding process

It must be seen that the weld is uniform and full (fish scale is the best), no indirect and no missing welds.

4. Whether the surface treatment of the shelf rack is good

The surface treatment of storage shelf racks, the surface spraying treatment of storage shelf racks should be uniform and strong adhesion. Whether the surface spraying of the shelf racks is even depends on whether there are any omissions on the inner edge of the shelf rack column holes. You can tap with a hard object during inspection. If it falls off easily, it indicates that the shelf rack is easy to rust.
