Otherwise the depth of the stone lintel is considering. The depth of stone lintel should be at least one mm per ten mm length of the opening.
3. Generally bricks lintels are consist of bricks which are placed on one end. The bricks should be burnt well, copper in color. It is free from cracks with sharp and square edges. The wood is temporary in support which is known as a turning piece. It is used to construct a brink lintel.Lintel
