The chestnut is a strong core tree, semi-hard, family of hardwoods. White or yellowish brown, slightly tinged with many nodes. The wood is elastic and durable, compact and with very low specific weight. Chestnut trees must be cut at the appropriate time, between two hundred and three hundred years. The too old chestnut trees are susceptible to diseases that deteriorate wood. It is used for internal and external joinery, cabinet making. For its excellent moisture resistance (if not subject to changes of environment and temperature), window frames, piles, barrels, vats and tubs.

The fir is a soft wood, the family of resins. It grows in the northern hemisphere, in temperate and cold zones. Its trunk can be as high as forty feet in height.

Two main varieties are known, said, the color of bark, fir and spruce. The fir is the quality less valuable. Its trunk is higher, but the fiber is coarser, it deteriorates rapidly and moth. It has high specific weight and is full of knots. The color of the wood is white, with reddish veins. It is used for packaging, scaffolding, beams, floors and frames inside, in a dry environment.

The spruce is typical of northern Europe. The wood is white when fresh. Seasoning becomes pale yellow. It has a low specific gravity, it works easily, is robust, flexible and can finish well. It ’more resistant than white fir wood and moisture from both the mechanical point of view. Its very straight trunk to recommend their use for masts, antennas, trees, boats, ships and buildings in general. Can be machined on the lathe and used for furniture, picture frames and musical instruments.

The Douglas fir wood belongs to medium heavy (dry density 470 kg/m3) with regard to the hardness is positioned just above the limit of soft wood (Brinell hardness of 20 N/mm2). The workability depends on the width of annual rings. The wood is easy to work with narrow rings, the rings it is often difficult to machine and crack easily, a pre-drilling before inserting nails and screws is absolutely necessary. The wood is easy to dry (after which we recommend as a seasoning as long as possible before the final processing), the paint and polish well. With regard to the natural durability Douglas falls in Class 3 and 4 (from an average of slightly durable), the impregnabilità is very scarce in the heartwood is medium to low in the cortex

The sycamore is a bit ’lighter than maple curl, dry density of 590 kg/m3 the first, the second 620 kg/m3. The wood is hard sliceable, his workmanship is problematic.The timber of all the maples can be easily cut. The flexural strength is good in the case of straight fiber. In particular, the sycamore is suitable to be milled, turned, drilled and carved. Its wood can soak well and can be subjected to any process of surface treatment. During the drying must be avoided to maintain long-moisture on high temperatures, as this may lead to the formation of unwanted colors. For the wood pile, you should use small strips and you should leave sufficient open space for good ventilation of the pile. The maple wood is not durable (durability class 5), it is well soaked, and attacked by termites (Anobium).

The maple wood is suitable for decorative veneer, veneer (plywood), furniture, flooring (parquets, wood floors and tables) and stairs. It is used in the construction of wind instruments (flute, bassoon, etc..) And the base of stringed instruments. Other areas of use are children’s toys, kitchen utensils (spoons, trenchers, etc..), Wood carving and sculptures.

Main physical and mechanical properties:
