[[Hardwood]] from North American trees has a variety of commercial uses, including in furniture, [[carpentry]], tools and musical instruments. Some timber is [[Sawmill|milled]] for [[plywood]], [[wood veneer]] and [[Framing (construction)|construction framing]], including structural support beams and [[Wall stud|studs]]. Logs can be fashioned into [[Post (structural)|posts]] and poles. Less sturdy timber is often ground and processed into [[pulpwood]], principally for [[papermaking]]. [[Resin]]s from sap yield [[wood tar]], [[turpentine]] or other [[terpene]]s. Some resins and other tree products contain dangerous toxins (not generally listed below). Much of the economic value of trees comes from [[orchard]]s and [[ornamental plant|ornamental]] uses.{{sfn|National Plant Data Team|2024|loc=[https://plants.usda.gov/assets/docs/PLANTS_Help_Document.pdf#page=35 Help Document] }}
