1. Structural characteristics of Douglas fir
Douglas fir is world-famous for its good strength weight ratio. Its high proportion can provide good nail holding force and fixation force, and is suitable for making wooden frames for residential buildings, small commercial buildings, multi-storey buildings and industrial buildings.
Among the soft wood species in North America, Douglas fir not only has a high elastic modulus, but also has excellent external bending fiber stress, tensile force along the grain, transverse shear force, transverse pressure and pressure along the grain. Because Douglas fir has these physical characteristics, as well as the durability of heartwood and excellent physical stability, many construction companies around the world use Douglas fir as the standard for judging all framing wood.
Douglas fir is famous for its structural performance and beautiful appearance. When large wooden beams, long-span or special shaped arches (such as churches, bridges and stadiums) are required for the design of structures, Douglas fir is often used as a wood species. In residential buildings, commercial buildings, public building structures Pagoda In the construction of buildings and water facilities, structural glued laminated beams made of Douglas fir are often used as horizontal load-bearing frames for houses, floors and pillars. Glued beams are also reliable building materials when building industrial plants, warehouses, garages and even building structures with beautiful appearance
2. Characteristics of appearance grade Douglas fir wood
Douglas fir has a light rose color and beautiful straight texture, and the color becomes dark after being exposed to the sun. The tenacious fiber of Douglas fir is not easy to cut or carve by hand, but only by using sharp electric tools and Machine tool You can get a smooth cutting face. This kind of wood can be processed into a variety of products along the shape of the grain, the surface is easy to paint, and can maintain various dyeing and varnish 。
3. Structural materials with a wide range of uses.
Douglas fir has a variety of uses. It is a structural material widely used by * * *, and is favored by engineers and builders. It is especially suitable for structural parts and heavy wood structures. It is also widely used in timber piles, * * * sleepers, sawmills, warehouses and countless other fields that focus on structural performance. Douglas fir, as a hard and stable wood, can be used to build wood frames for light and heavy buildings.
Because of its high strength and good bonding property, Douglas fir is often used to make gluing beams for various structures, including indoor sports fields, swimming pools, churches and supermarkets.
Douglas fir has a good appearance and is easy to process, which is very suitable for processing into window Box and door Frames, wood lines, cabinets and other joinery products. The hardness and strength of Douglas fir also increase the durability.
Douglas fir has high corrosion resistance and good structural performance, so it is also the main wood for making industrial liquid tanks, barrels and other storage containers. Its stability and ease of processing also make it a material choice for manufacturing industrial parts.
