What's the name of the stone above the door during the renovation?

Generally, there will be bricks on the upper part of the door, so a small beam is needed as a support to avoid crushing the door. This kind of trabecula is called lintel. 1. When there are doors and windows on the wall, and the hole of the wall is more than 300mm, in order to bear all kinds of loads from the upper masonry of the hole and transfer these loads to the walls on both sides of the hole, such as doors and windows, beams are often set on the doors and windows, which are called lintels. 2. The lintel forms are reinforced brick lintel, brick flat arch lintel, brick arch lintel, reinforced concrete lintel, brick wedge arch lintel, brick semicircle arch lintel and wood lintel.
