A lintel is a horizontal structural element placed over openings such as doors and windows. It supports the weight of the wall or structure above, distributing the load to the adjacent walls. Lintels can be made from various materials, including wood, steel, and reinforced concrete, depending on the building's design and requirements. In architecture, lintels are essential for maintaining the integrity of a building while allowing for openings. They come in different styles and sizes, often designed to complement the overall aesthetic of the structure. Proper installation of a lintel is crucial for safety and stability in construction.
