1. A 9-door locker refers to a locker with 9 doors at the front, which can be used by 9 people. Inside the locker, the upper part of the door is for hanging clothes, while the lower part has storage compartments.

2. Basic requirements for lockers: They are commonly made of 0.7mm or 0.8mm thick stainless steel plates and feature a 45-degree slanted top to prevent dust accumulation. Sometimes, this design also prevents employees from placing items on top, avoiding accidental drops and injuries. The locker doors are equipped with label slots, ventilation holes, and include internal clothing rods and shelves.

3. Locker room materials: The most common material is stainless steel, including the locker doors. Some locker doors can be customized with glass upon request, making them suitable for a wider range of applications.

4. Locker door locks: Mechanical locks or combination locks can be used. When the number of locker doors is limited, combination locks are preferred as they eliminate the need to carry keys, reduce the risk of loss, and minimize item contamination. Many people today prefer not to carry too many items and often misplace them, making combination locks more widely used.

5. Standard dimensions are 1000*420*1800-1950 and 1200*420*1800-1950.
