The width of the edging boards and beams measured anywhere in length, with no wane, but no closer than 150 mm from the ends. The width of the edging boards and beams with non-parallel edges, measured at mid-length. The width is measured on the boards unedged middle of the length of the floor as the sum of the widths both layer (bark and phloem). The measurement result is rounded up to 10 mm to 5 mm fraction does not take into account the shares of 5 mm or more say over 10 mm '. In Estonia and other Baltic countries there is a reverse situation, which can not be called fraud, but rather a manipulation. Most exporters of sawn timber and saw familiar paid sizes, which indicate in their procurement specifications, their partners from abroad. In fact, this is reason: lumber natural moisture and lose moisture during the drying process, reduces the width and thickness.
Foreign consumers say they do not want to pay for water. It is therefore indicated and saw paid sizes. No trick here is complete. The thing is that very often the size of transcripts slightly less than the size of lumber after drying. These 1-2 mm immediately become super profit for the importers of sawn timber. Recipe counteract this phenomenon is simple – to require foreign partners specify in the contract prices saw the size of which will be at the same time and scoring. Not to be trapped, we must remember the most important rule: purchase Edged board, timber and other timber with no arms, not 'cheap' and reliable and proven timber processing companies, where you will talk about all the competence of the acquired products.
