Trusses are structural elements, usually made of wood, steel or concrete, which form the skeleton of the roof, transferring loads from the roofing to the load-bearing walls of the building. They consist of beams connected in triangular arrangements, which gives them great strength and stability. Trusses are primarily used in residential and industrial construction, and their design allows for the construction of long-span roofs without the need for internal supports. As a result, truss-based roofs are more economical and easier to install.
