What material is NOT typically specified on a rope tag?

The material that is typically not specified on a rope tag is plastic. Rope tags are important for providing essential information about the type, manufacturer, and specifications of the elevator ropes, specifically for safety and compliance purposes.

Steel, aluminum, and fiber materials correspond to the traditional categories of rope used in elevator applications, which usually include wire ropes made of steel for durability and strength, aluminum for lightweight applications, and fiber for certain types of lifting and rigging where flexibility is required.

Plastic, on the other hand, is not a material commonly associated with the construction of elevator ropes. While plastic may be used in other elevator components or tagging methods, it does not fulfill the same mechanical properties or safety requirements needed for the ropes themselves. Thus, it would not typically be listed on a rope tag.
