What is lintl?

A lintel is a horizontal beam or support structure that spans an opening, such as a doorway or window, to support the weight of the structure above it. It is typically made of wood, stone, concrete, or steel and is placed above the opening, creating an arch or a flat surface. Lintels are important components of buildings as they help distribute the weight of the structure across the opening and prevent any collapses or deformations. The proper design, installation, and maintenance of lintels are critical to the safety and longevity of a building.
