Edged board in construction

One of the most common specieslumber is edging board. It is made by cutting from a solid log. At the same time, the edges are cut in such a way that they do not have a crust (survey). In some cases, such a defect is present in a small amount. Most often its magnitude is regulated by the GOST standards. This type of sawn timber is widely used in construction.

In Russia, the sale of edged boards is carried out inseveral standard sizes. So, the product is produced with a thickness of 22, 25, 30, 40, 50, 100 or 150 mm, width 100, 150 and 200 mm, and the length can be 3, 4 or the most common option - 6 meters. At performance of works the most optimum variant of dimensions which allow to use as much as possible effectively an edging saw timber, ensuring thus necessary reliability of a design is selected. It is also worth noting that it is possible to produce boards for individual orders in case a certain size is required.

In addition to the differences in size, the edged boardis also characterized by wood species, surface cleanliness, the number of completed processing processes. Together, all these indicators determine the grade of lumber. And it is this criterion that mainly shapes the cost of the product and, of course, the quality.

Edged board is divided into five varieties, namely: the best (the best) and the 1st, the 2nd, the 3rd and the 4th. The indicator is assigned to the lumber according to GOST 6564-84.

In construction, boards frompine, spruce, larch, birch, etc. Each of these types of wood has its own specific pluses and minuses. The choice largely depends on the area of ​​application of lumber, operating conditions, design.

In many respects the quality of edging boards is determinedconditions of their storage. Most often they are stacked. In this case, it is necessary to ensure good air circulation, in particular - its inflow inside the laid sawn timber. Due to this, drying of the wood is carried out, and the boards do not rot.

In addition, in order to preserve the original form andquality, the edging board is processed by special antiseptics, protecting from decay, defeat by fungi, wood-breaking insects. Manufacturers, as a rule, carry out such treatment under high pressure, resulting in a deeper penetration of the composition into the material. That, accordingly, leads to better protection of the material. The product treated in this way will last long and reliably.

The edging board is widely used inconstruction both in the performance of certain works, and for the creation of concrete structures, both for interior decoration and for exterior. Most often, the edging board is used for the installation of floors, as well as for the erection of the roof, the manufacture of ceilings, skeleton for partitions, rough floors and much more. It finds its use of lumber in the production of furniture. For rough finishing, the boards of a lower grade are selected, for the important elements of the building the best quality sawn timber is used.
