Do single-row high-rise shelves need walls? Are there any relevant standards?

Yes, there are no relevant standards. Single-row high-rise shelves need to be connected with the wall during installation, which is helpful to improve the stability and safety of the whole shelf system. Special connectors, anchor bolts or welding can be used to connect the shelf with the wall. There are corresponding building codes and safety standards in various places, including the requirements for the installation and connection of shelf systems. You can consult local architects, engineers or relevant regulatory agencies to obtain more accurate information and follow the applicable building codes and standards to ensure the correct installation and use of shelves.
