Many people prefer imported boards, such as red oak and white Ash wood in the United States. These materials belong to hardwood. As far as China is concerned, what kinds of hardwood are commonly imported from the United States, do you know?
Broad-leaved wood in the United States provides a large number of different colors, textures and properties of wood for specification makers, manufacturers and end users around the world, including walnut, birch, elm, cherry and red oak with darker warm tones, as well as lighter white oak, maple and white Ash.
Red oak, widely distributed in the eastern part of the United States, is hard and heavy wood with good machinability and slow drying. The color, texture, characteristics and properties of red oak vary with the origin.
White oak, North American white oak, similar to Chinese oak and European white oak, is widely produced in the eastern United States. Its sapwood is light-colored, its heartwood is light brown to dark brown, its texture is rough, most of them are straight lines, and its pulp ray is longer than red oak, so it has more wood grain than red oak, its wood is hard and heavy, its mechanical processing performance, dyeing and polishing performance is good.
White Ash is also known as Fraxinus mandshurica and Sophora japonica. The appearance of North American white Ash wood is similar to that of European white wax wood. The white wood part is light in color and nearly white. The color of heartwood varies from brown gray to light brown, to light yellow with brown wood grain. This wood is usually straight and has a rough, even texture. The chroma and supply of light white wood vary with the origin.
Cherry, in various parts of the eastern United States, is the main commercial forest in Pennsylvania, Virginia, West Virginia and New York. The color of heartwood changed from bright red to brown red, and became darker after sunshine. On the contrary, its white wood is milky white. Cherry trees have fine, uniform, straight lines, smooth texture, inherently Brown heart spots and small gum nests. Cherry is characterized by heartwood. Its price is closely related to the proportion of heartwood. There are color selection and non-color selection. The higher the color selection ratio, the higher the price.
Soft maple, mainly distributed in the eastern part of the United States, has a small number in the West Bank (Daphne maple). It is similar to hard maple in growth environment. Most of its properties are very similar to hard maple and can be used to replace hard maple. Generally speaking, the white wood of soft maple is grayish white, sometimes with dark pulp spots. Its heartwood color ranges from light brown red to dark brown red. This wood is usually straight grain.
Hard maple, mainly distributed in the eastern United States, is a cold-resistant tree, preferring a northern climate. The hardness of hard maple is about 25% stronger than that of soft maple. The white wood is milky white with brown-red tone and the heartwood is light brown-red to dark brown-red. The number of dark brown-red heartwood varies obviously with the growing area. Both white wood and heartwood may contain pulp spots.
Walnut wood, walnut wood sapwood is white, with brown tone, its heartwood is light white to brown red. Both sapwood and heartwood have rough texture, and the wood grain is usually straight, but it will fluctuate or irregular. The density and strength of walnut wood vary with its growth rate. The value of real walnut wood is usually higher than that of Pecan wood. Walnut wood is famous for its excellent strength and seismic performance, and has excellent steam bending resistance.
Black walnut, walnut white wood is milky white, heartwood is light brown to brown black, occasionally with purple cracks and dark stripes. The walnut supplied can be sold only after steam treatment to discolor the white wood, or without steam treatment. Walnut is usually straight wood grain, but also with corrugated or curved wood grain, producing attractive, decorative graphics.
Liriodendron chinensis, widely distributed in the eastern United States, has milky white wood and may have stripes. Its heartwood is pale yellow-brown to olive-green, and its inherent characteristics are more heartwood. The green color of the heartwood darkens and turns brown when exposed to light. Liriodendron chinensis has medium texture density and straight grain. The size and some physical properties of the white xylem layer of Liriodendron chinensis varying with the origin.
Alnus alba is distributed on the west coast of the United States and in the Northwest Pacific Ocean. When Alnus Alba has just been cut down, it is almost white and quickly turns pale brown with yellow or reddish hues after air contact. Older trees have heartwood formation, no obvious boundary between sapwood and heartwood, the wood is quite straight and the texture is uniform.
