Oak is the common name for about 400 species of trees and shrubs belonging to the genus Quercus of the Fagaceae family. It is an evergreen and deciduous species grown mainly in the Northern Hemisphere.

The Oak tree has rounded leaves, with lobed margins in many species; some have serrated or whole-shaped leaf blades. Its flower has squirreltails form, blooming in the spring. Its fruit is known as an acorn, which grows in a cup-shaped structure; each acorn contains 1 seed (rarely 2 or 3) and takes 6–18 months to ripen, depending on the species. A mature Oak tree can grow up to 100 feet high and 50 inches in diameter. They are full-grown and begin to flower around 20 years.

Oak wood is usually imported officially from the US and European countries such as the Czech Republic, England, France, and Germany. Furniture products made from Oak always create a sense of harmony with natural light, youthfulness, warmth, and modernity.

It is not always easy to tell the difference between many types of Oak based on color. A piece of natural Oak can have minimal color variation; they mainly have pale yellow (beige) to dark brown color. While white Oak color tends to look more like beige, the color of red Oak is brown, which looks more ruddy. Furthermore, an Oak log can have contrasting shades of color throughout a log. Both red and white Oak can hold color well when coated.

The tom of Oak wood is usually smooth and striped. In the normal coating process, a wood tom filling liquid must be used to finish. The Oak grain has the ellipse (ovan) shape and the wood-fibre has tiny crevices just like falling raindrops. The parts with eyes or near the root of the tree are often large, and looks quite similar to the grain of ash wood.

In terms of hardness, through the Janka durometer, white Oak has a hardness of 1360 lbf; red Oak is 1290 lbf. Compared to common woods in Europe, such as walnut, cherry, and maple, Oak is much harder.

Oak has a "bottle-like" structure so that the wood cells attach firmly together, which is also waterproof. With this feature, Oak wood is often used to make wine barrels and outdoor furniture. In addition, Oak is tough to be rotted, so it is used to build boats, containers, and wharves.

Oak has an excellent overall compression resistance, and the impact resistance is high. The wood has medium hardness but strong bearing capacity, especially since it can be easily bent by steam while processing furniture.

The Oak core has good resistance to termites, making Oak furniture always long-lasting and beautiful.

Good mechanical resistance and good adhesion to the nail even when drilling right before the time of nailing.

Good resistance to harsh environmental conditions due to being grown in regions with a cold climate.

The grain is even and beautiful with a pleasant scent.

Oak wood is relatively slow to dry and easy to crack when drying.

The wood is easily deformed when dry because of its significant shrinkage.

This wood line reacts with an iron saw blade which might create color stains.

Wood dust may cause mild eye and skin irritation.
