A lintel is a horizontal structural element placed over an opening, such as a door or window, to support the weight of the wall or structure above it. Typically made from materials like wood, steel, or reinforced concrete, lintels help distribute loads evenly, preventing the wall from collapsing. They are essential in both residential and commercial buildings. In architecture, lintels can also serve decorative purposes, enhancing the aesthetic appeal of a structure. Different styles of lintels, such as architraves or keystones, can be used to complement various architectural designs, contributing to the overall character of a building.
