For construction and repair, high -quality lumber are always in demand, which are represented not only by a fresh cut. Harvesting of natural wood, specially dried in drying chambers, where wood humidity is brought to indicators of 8-9%, can be purchased from the warehouse, selecting the required items and the corresponding parameters in the price of building materials. It should be noted that the beam, which is usually made of spruce or pine, is considered to be in the form of a workpiece made of wood, with the corresponding cut on four sides (usually starting from 100×100 mm in cross section).Choosing a high -quality material necessary for repair or construction, among which many order a beam, for internal work it is fundamentally important, like the reproductive board, to choose well and qualitatively dried blanks, which will avoid warping and other deformations of operated products. Thus, cracking can be avoided, as well as when performing various works regarding repair or construction, to withstand the approved parameters in particularly accurate structures. This also applies to furniture production, where a beam is usually used in the construction of various frames for upholstered furniture.
