Method for distinguishing the quality of warehouse shelves.wire shelving units on wheels maker

　　(1) The materials used for warehouse shelves are generally cold rolled steel profiles, preferably using national standards. However, there are few manufacturers using national standards (mainly due to their high prices), so the simplest inspection method is to conduct tests based on the agreed bearing capacity between both parties. The material for heavy-duty warehouse shelves should be the best for Baosteel.

　　(2) The structure of warehouse shelves. The structure of the columns of the shelf depends on whether the bending of the cross-section is becoming more uniform, and a more uniform and symmetrical shelf indicates a good structure. The crossbeam of the shelf depends on the hook structure of the crossbeam and the form of the crossbeam hanging on the column: the more hooks on the crossbeam, the better, and the greater the force, the better; Hang the hook of the crossbeam on the column to see if the contact between the hook and the column is tight and consistent. The inner side of the hook should be close to the side of the column without gaps, so that the structure can be stable, stressed, and durable.

　　(3) The welding process must be based on the uniformity and fullness of the joint (fish scale is the best), and there must be no indirect welding or leakage welding.

　　(4) Surface treatment of warehouse shelves. The spraying treatment of shelves should be uniform and have strong adhesion. Check if the surface of the shelf is evenly sprayed and if there are any omissions on the inner edge of the shelf column holes. If it easily falls off, it means that the shelves are prone to rusting.
