The metal skin on the outside of the frame is typically made from steel, although aluminum and other metals can also be used.

Hollow metal doors are designed to be strong and durable, making them ideal for high-traffic areas and environments where security is a concern. They are commonly used in commercial buildings, schools, hospitals, and industrial facilities.
