Many people prefer imported plates, such as American red oak, ash, etc. These materials are all hardwoods. For domestic purposes, what are the more common types of hardwood imported from the United States? Do you know?

Hardwoods in the United States provide a large number of woods of different colors, textures and properties to specifiers, manufacturers and end users around the world. Among them are warmer walnuts, birch, beech, cherry, and red. Oak also has lighter white oak, maple, and ash wood.

Red Oak, widely distributed in the eastern United States, is hard and heavy, has good machining performance, and is slow to dry; red oak's color, texture, characteristics and properties will change with the origin.

White Oak, North American White Oak is similar in appearance to Chinese beech wood and European white oak. It is produced in large quantities in the eastern United States. Its sapwood is light-colored, its heartwood is light brown to dark brown, and its texture is rough. Most of it is straight-grained. The ray is longer than the red oak, so it has more wood grain than the red oak, hard and heavy wood, mechanical processing performance, good dyeing and polishing performance.

White wax is also known as ash, north beak and so on. The appearance of North American ash wood is similar to that of European ash wood, and the white wood is light in color and almost white. The color of the heartwood is from brownish gray to light brown, to a brownish-yellow woodgrain change. This kind of wood is usually flat with a rough uniform texture. The color and the supply of light-colored white wood vary with origin.

Cherry, in various parts of the eastern United States, the main commercial forest is located in Pennsylvania, Virginia, West Virginia and New York. The color of the heartwood is from brilliant red to reddish brown, and the color becomes darker after sun exposure. Instead, its white wood is milky white. The cherry wood has a fine and even grain, a smooth texture, and naturally contains brown tree spots and tiny gum nests. Cherry is characterized by its heartwood. Its price is very much related to the proportion of heartwood. There is a situation where color selection is not selected. The higher the color selection ratio, the higher the price.

Soft maple, mainly distributed in various parts of the eastern part of the United States, has a relatively small number of western shores (leaf maple). It has a similar growth environment to hard maple, and most of its properties are similar to those of hard maple, and can be used as an alternative to hard maple. In general, white wood of soft maple is off-white, sometimes with deeper colored pith spots. Its heartwood color is light brown red to dark brown red. This kind of wood is usually straight wood grain.

Hard Maple, which is mainly distributed in the eastern United States, is a hardy tree that prefers the northern climate. The hardness of hard maple is about 25% stronger than that of soft maple. The white wood is milky white with a brownish-red tone. The heartwood is light brown-red to dark brown-red. The number of dark brown red heartwoods varies significantly with the area of growth. Both white wood and heartwood may contain pith spots.

Walnut and walnut sapwood are white with brown shades. The heartwood is pale to brownish red. Both sapwood and heartwood have a rough texture. The wood grain is usually ruled but it fluctuates or irregular. Walnut's density and strength vary with its growth rate, and true walnuts are generally worth more than hickory. Walnut is known for its excellent strength and shock resistance, and it has excellent steam bending resistance.

Black Walnut, Walnut's white wood is milky white, heartwood is light brown to brownish black, occasionally with purplish cracks and darker stripes. The supply of walnut wood may be steamed first to change the color of white wood before sale, or it may be sold without steam treatment. Walnut is usually a straight wood grain, with corrugated or curved wood grain, producing an attractive, decorative graphic.

Liriodendron chinense, widely distributed in the eastern part of the United States, is a milky white, white wood, may have stripes, heartwood is light yellow-brown to olive green, inherent characteristics are more heartwood. The green color of the heartwood will darken and turn brown. Liriodendron wood texture medium density, straight wood grain. The size and some of the physical characteristics of the white wood layer of Liriodendron chinense will vary with the place of production.

Alder, distributed on the west coast of the United States and the Pacific Northwest. When alder was cut down, it was nearly white and quickly turned into light brown after contact with air, with a yellow or light red hue. Older trees have heartwood formation, and there is no clear demarcation between sapwood and heartwood. The wood is straight and the texture is uniform.

Unlike China, only 27% of the United States' forest land is owned by the government, enterprises, and institutions, and the remaining 73% are private. Over the past 50 years, the US’s forest cover has risen instead of falling, and the logging rate is far away. Below the growth rate of the forest.
