Which of the following is NOT true about typical elevator door entrance frames?

Elevator door entrance frames are critical components designed with specific safety and operational standards in mind. When considering the assertion that they are always fire rated, it's important to note that while some elevator door entrance frames do have fire-resistant qualities, it is not universally required for all frames. Fire ratings depend on factors such as the building’s design, local codes, and the specific type of elevator installation. Therefore, it is inaccurate to claim that all frames must possess a fire rating, making the statement that they are always fire rated not true.

In many cases, elevator door frames can receive different ratings, like the 'B' label rating, which indicates a certain level of fire resistance, and they are predominantly made of durable materials such as steel due to its strength and safety properties. Furthermore, the design of these frames is often intended to enhance fire protection, further emphasizing the variances in requirements and applications across different scenarios. Understanding these distinctions helps clarify that the assertion regarding universal fire rating does not hold true for every elevator door entrance frame.
