Raw Material
Wood is a living and evolving material.
If well treated, it restores warmth and well-being.
OAK
One of the most common trees in our woods is the oak, from which oak is obtained.

Oak Wood: Characteristics and Applications
Lightweight and strong
The Quercus genus is represented by over 500 different species, which live in all temperate zones of the earth. In Italy the most used from an industrial point of view is the Q. sessiflora (oak). It was once believed that English oak, oak and downy oak were subspecies of the Q. Kohur. Nowadays it is preferred to give a more exact botanical definition, for which the species Q. pedunculuta defines the English oak, the Q. pubescens the rovella and the Q. sessiflora the oak.
The botanical differences are however very small and also the technological characteristics of use practically common to the various species. European oak, Japanese oak and American oak, although commercially distinct, are similar in character. The best oak wood comes from trees grown in the woods, which can reach 30 meters in height and have a long and straight trunk up to one meter in diameter; the old trees of the parks sometimes have a wider trunk, often with low branches.
It has always been one of the most widely used woods in all sectors of application. From naval construction to civil constructions, for carter jobs, to furniture; both as solid and as sliced. As poles, also immersed in water, for barrels, floor boards, railway sleepers, etc. Joints with nails and screws hold well even if pre-drilling of the seats is recommended.
It is easy to work, it can be painted and varnished without any particular problems. Many fine examples of structural, carpentry and decoration uses can be seen in historic buildings. Today it is still an important structural wood when traditional looks or strength and durability are required. It is used for building boats, especially fishing boats, and for gates and poles. It is an important furniture wood and is used for joinery, paneling and flooring in homes; a special use is for whiskey barrel staves and sherry barrels.
Types
From a commercial point of view, there are three types of oak, sharing the same technological characteristics and uses. They are distinguished according to their origin:
- American oak, which includes American white oak (Quercus alba) and American red oak (Quercus rubra), which, as the name implies, differ in color.
- European oak, which like the American oak includes white oak (Quercus robur instead of alba) and red oak (Quercus rubra).
- Japanese oak, which includes Quercus myrsinifolia and Quercus glauca.
For oak intended for parquet, we have the following varieties:
- Natural oak, a classic that never sets.
- Brushed oak, with the grain in relief.
- Sandblasted oak, the right balance between classic and modern.
- Bleached oak, is the most popular because it allows you to create bright and sunny environments.
- Antique oak, with warm and traditional colors.
Uses
It is a highly valued wood for its many positive characteristics and lends itself to various uses. The main ones are:
- Construction of fine and long-lasting furniture.
- Construction of small boats.
- Construction of fine barrels for aging wines.
- Construction of load-bearing structures in buildings.
Realization of
- Firewood, produces a high amount of heat and a low smoke density.

Pros and Cons
Based on the characteristics we have already seen, oak has numerous advantages and the only "defect" that we would like to point out is the fairly high cost which, however, is repaid over time thanks to the numerous qualities. Let's summarize the main ones: High hardness and toughness, see the characteristics. High resistance to bad weather and atmospheric agents, see the characteristics. Good durability, see the features. Medium high price. Pay particular attention to parquet which, despite being very resistant, is not free from scratches and dents.

Oak wood has been highly prized since ancient times for shipbuilding, maritime, hydraulic and road construction, for load-bearing structures and various carpentry and heavy joinery in general. In addition to these uses, which are of primary importance, it is also worth mentioning the flooring, the cooper's work (tubs, barrels, various containers), the furniture (which are however very heavy), the internal and external fixtures and the railway sleepers.
This last use, for which oak wood proves to be excellent even without the application of preservation treatments, is the primary cause of the disappearance of many oak woods which occurred in the second half of the last century in conjunction with the development of railway network. A last use, of moderate economic interest, is that of decoration with cut veneers.
The substantial demand for oak wood for the various uses mentioned above cannot be covered by Italian availability and it is therefore necessary to resort to massive imports: however, this is not only a problem of quantity but also of quality since the material coming from France, the former Yugoslavia and Poland is judged to be much better than ours both in terms of workability and appearance.
Such an indisputable fact essentially depends on the oak forests of these countries being made up of Farnia and not of Rovere (sensu stricto) which, on the other hand, together with Roverella predominates in Italy. Regarding the material of Yugoslav origin, it should be borne in mind that the wording «Rovere di Siavonia» currently used in the trade is not correct, as it is actually Farnia.
