The lintel is the floor between wooden beams for inserting the filler material. Hinges are an inseparable part of the roofing work. This is a supporting skeleton under the roof covering. The shutter is made of wood because it offers excellent features such as lightweight machinability, low bulk density, compressive strength and bending. The design of the latch differs according to the type of ceiling and the distance of the ceilings. It is translatable, sloped or recessed from coarse, unbloted planks with sealed joints against flooding of the embankment. OSB boards are used on the roof. If the lid is used, the load on the roof will increase before the snow.
