Huaqisong is famous for its structural performance and beautiful appearance. When designing structures that require large wooden beams, long spans, or specially shaped arches (such as churches, bridges, and sports arenas), Douglas fir is a commonly used type of wood. In the construction of residential, commercial, public building structures, tower buildings, and water facilities, laminated beams made of Douglas fir are commonly used as horizontal load-bearing frames for roofs, floors, and pillars. When constructing industrial plants, warehouses, garages, and even building structures that require a beautiful appearance, glued laminated beams are also reliable building materials.
