Commonly known varieties are the [[European beech]] tree (''F. sylvatica'') and the [[American beech]] (''F. grandifolia''). The pale reddish-brown, close-grain beechwood is hard and heavy. It bends well, is durable under water, and gives a smooth shiny finish. Beech is a commonly used timber for flooring, cabinetry, furniture (especially bentwood chairs), veneer, plywood, tool handles, and turnery. It was used in panel paintings in western Europe. Beech nuts provide forage for game animals and yield an edible oil. | Deciduous, smooth-bark trees of the genus ''Fagus'' native to temperate regions of the northern hemisphere.

Description
Deciduous, smooth-bark trees of the genus Fagus native to temperate regions of the northern hemisphere. Commonly known varieties are the European beech tree (F. sylvatica) and the American beech (F. grandifolia). The pale reddish-brown, close-grain beechwood is hard and heavy. It bends well, is durable under water, and gives a smooth shiny finish. Beech is a commonly used timber for flooring, cabinetry, furniture (especially bentwood chairs), veneer, plywood, tool handles, and turnery. It was used in panel paintings in western Europe. Beech nuts provide forage for game animals and yield an edible oil.

Risks
Skin contact and dust inhalation may cause irritation and allergies.
May evolve volatile organic acids.
Physical and Chemical Properties
Large trees growing to 35 m. Bark=smooth, gray. Leaves=simple with veins and toothed edges. Fruit=Large husk containing 2 shiny brown edible nuts.
Wood is acidic. Color: Pinkish brown with dark brown rays. Rings: obscure. Pores: diffuse, fine. Grain: faint. Rays: distinct. Hard, strong and heavy. Specific gravity = 0.7-0.9. Density = 43-56 ppcf
Paper fiber type: hardwood, diffuse porous. Using transmitted light microscopy, pulp is identified by medium to long vessels with elongated, alternate pitting. Perforations are simple, but smaller vessels can have scalariform on one end . Appearance with Graff "C" stain: dark blue, but varies with bleaching. Average dimensions of fibers: length, 1.2mm. 21μm wide. Common pulping method: kraft.
