In the joinery workshop, which has a daily production capacity of 85 windows, the desired thickness, size, threading, grooving and planing operations are performed by fully automatic machines.

The logs that enter Semitaş’s integrated facilities as raw materials are processed and impregnated in the cutting and joinery workshops and then made ready for use. Here, ecological furniture, which is many times more durable and ergonomic than the furniture made of unimpregnated wood, is produced and all kinds of wooden materials are manufactured and applied.

Profiling machine: The fully automatic CNC profiling machine can plan and shape four surfaces of the wood material at the same time.

Minimum waste rate: In the plant, where fully automatic CNC machines are in operation, which give geometrical size, shape and dimension to the wood, the production is carried out by expert teams with the minimum waste rate.

Drying oven: In the drying process, which is realized by giving hot steam, the moisture content of the wood material is reduced from 40-60% moisture content to 10-12% without deformation and cracking.

Impregnated Wood: The wood manufactured in the art and joinery workshops of Semitaş Anonim Şirketi is impregnated according to its intended use. Impregnation, which is the process of extracting the sap that causes bacterial growth and decay from the wood and replacing it with protective substances impregnated under pressure, makes the wood stronger than concrete and more durable than steel.

The impregnation, which penetrates at least 4 cm into the wood from all sides, prevents rotting and protects the wood from pests such as fungi, insects, termites and sea worms, increasing its life span tenfold. Semitaş carries out three different impregnation processes, which are applied with a vacuum-pressure system and are named with their colors in the sector, according to the area of use of the wood: Green Impregnation, Brown Impregnation and Natural Impregnation.

Green Impregnation: Wood materials impregnated in a vacuum-pressure unit, which gives the wood a light green color, have a wide range of uses. Green impregnated wood materials are used in parks and gardens in contact with soil and water, exterior construction of villas and similar residences, farm buildings, barns, roofs, greenhouses, sea piers, electric and telephone poles, bridges, pergolas, sheds, terraces and swimming pools, interior and exterior spaces of tourist facilities in contact with water, environmental furniture used in areas such as urban forests and recreational areas, poles used to support trees in vineyards and gardens, and garden fences.

Brown impregnation Brown impregnation is applied to the wooden materials that are used in the interior and exterior to give an air of old age, such as ceilings, roofs, balcony pergolas. While the brown impregnation prolongs the life of the used wooden material many times over, it adds a different beauty to the rooms with its different color.

Natural Impregnation: Natural impregnation is used for doors, window joinery and interior wood materials in Semitaş integrated facilities. The natural color of natural impregnated wood material does not change. It serves for many years without the need for painting and maintenance.

Laminated and Solid Wood

Wood is more resistant to disasters such as earthquakes and fire than concrete and steel. Laminated wood is made by gluing the wood material together with cold glue and pressing. The strength of the laminated material, which

allows the desired length and dimensions to be achieved, increases by 50-75% compared to normal wood material. The strength of the wood material glued and pressed together and produced as a laminate

is increased by up to 50%. It is also possible to produce straight or curved beams. The logs delivered to the wood shop are first debarked. They are then cut into lamellas of the desired size and sent to the drying oven.
