Wood raw material is widely used in construction, where it is used as a building material. In addition, some types of roofs are made from wood, wood is indispensable in finishing works, as well as in the production of floors and parquet. Various elements of furniture, stairs, gazebos, windows, entrance and interior doors are made from this raw material. The main raw material in the woodworking industry is sawn timber. Their use in construction has reached a significant scale. Hardwood lumber is ideal for joinery and furniture work, while softwood lumber is used for windows, doors and floors.
Lumber is called wood products obtained as a result of longitudinal sawing of round wood, which in practice means performing the process of sawing wood with a tool parallel to its longitudinal axis. The production of lumber takes place on vertical or band saws designed for logs. The former are used for group sawing, which significantly increases the efficiency of the work compared to the old method, which results in only one piece of lumber.
For group friction, a given saw coupling is used, that is, a set of gang saws that are spaced enough to obtain a given thickness of lumber. As a result, the elements are produced with the least loss of sawn material. /p>
Wood for lumber production
Lumber can be divided by the type and type of wood from which they are made. Depending on the species of trees used, there are:
- oak lumber;
- birch lumber;
- spruce lumber;
- beech lumber;
- pine lumber.
Drying and storage of lumber
Before wood goes on sale, it goes through a thorough drying process. As a result, the lumber reaches a moisture level similar to that in which it will eventually be used. The hardness of the lumber increases, the quality of processing improves and its high resistance to external factors is achieved. origin.
In order for wood raw materials to retain their original properties and not to deform, and also not to be adversely affected by weather conditions, it must be properly stored. Otherwise, it will not be suitable for further use. Building lumber should be stored in piles outdoors or in a specially adapted room with an air flow. The stacks are built on concrete�
