Lumber can be qualified on the method of processing, size, shape and wood species. Knowing these qualifying features, you'll be able to pick up those construction materials that are most appropriate to solve your goals. In addition, the type of the selected materials will be directly affected their qualitative characteristics. In this regard, it is important to know what types of timber can be produced by the manufacturers.
The materials according to the method of treatment can be circumcised and the uncircumcised. In the truncated products of all four sides of the Board or timber are processed, the purpose of which is to create a level surface. As a rule, such wood is used for interior decoration. Uncircumcised materials after cutting the logs do not undergo additional processing and are used to generate designs, which do not need to have a clean, smooth surface.
Choosing timber, you probably first of all pay attention to what he has the shape and size. Currently, the most widely forms, such as slats, boards, rods and bars, sleepers, quarters and half-logs. The most common material by far are the Board. They may have a thickness up to 100 mm and a width of twice the thickness.
No less popular in the construction and Assembly of various structures used by the timber. He may have a width and a thickness over 100 mm and characterized by high resistance to mechanical loads. Croaker is waste wood, which are quite frequently used when building different structures. For example, if you want to build a temporary forest or to put the fence, then slab it will fit perfectly.
The wood species of the considered materials can be softwood or hardwood. As has become clear from the title, softwood lumber made from softwood: spruce, pine, larch, cedar, fir. After cutting out the deciduous oak, aspen, birch, beech, poplar, maple etc. Each type of wood has its own specific properties. For example, oak has a high hardness, and El contains in its structure a large number of resins.
