1.The material of the warehouse pallet racking systems: There does not seem to be a set of strict and complete shelf industry standards in China, but the material of the shelf is preferably SS400 steel.

2.The structure of thepallet racking storage: the shelf column depends on whether there are many and uniform bends in the section. The more uniform and symmetrical the structure, the better.

3.The beam of the heavy duty pallet rack shall be subject to the hook structure of the beam and the form of the beam hanging to the column: it is better to have more hooks on the beam, and the more forces the better. The hook of the beam shall be hung on the column according to whether the contact between the hook and the column is close and consistent, and the inside of the hook shall be close to the side of the column without clearance, so that the structure can be stable and durable under stress.

4.Surface treatment of the shelf: the surface of the shelf shall be sprayed evenly with strong adhesion. Whether the surface of the shelf is sprayed evenly depends on whether there is any omission at the inner edge of the shelf column hole. The shelf is easy to rust if it is easy to fall off by tapping hard objects during inspection.

5.Welding process: This is the best identification.

Handling operation: mainly refers to the horizontal or vertical movement of objects by human or mechanical force

Characteristics of handling operation: the handling shelves and goods are not fixed, and the site is not fixed.
