lintel

This term describes a specific architectural element that bears the weight of a structure above an opening. It is most commonly associated with traditional masonry, where a heavy stone or wooden beam is required to prevent the wall from collapsing into the void of a door or window. In modern construction, the term remains standard regardless of the material used, whether it be reinforced concrete or steel. It is a technical term used primarily by architects, masons, and builders to specify the load-bearing component of a portal.
