In the process of carrying out a wide variety of construction work, a wide variety of lumber is used. Usually, wood is sold in an already dried state, but sometimes raw wood can be seen in specialized retail outlets. Based on what exactly has to be done, you can buy lumber in the form of a ridge or solid round wood, a garter, a handrail, plates, quarters, a leg of a bar, an edged board.
If a carpenter or a worker places an advertisement for the purchase of lumber, then he is primarily interested in the type of wood that was used in the process of making the lumber. And this point is very important, since wood of different species has different operational properties, therefore it can be used for different purposes..
As a rule, all types of lumber that are used in the construction process have their own specific names. Such materials also vary in thickness and in width-to-thickness ratios. For example, boards should be made taking into account this proportion of at least two and a maximum thickness of no more than 100 mm. For sawn timber made from hardwood, the maximum length is set at 5 meters. Softwood lumber can be slightly longer — up to 6.5 meters.
As noted earlier, lumber is used for the manufacture of a wide variety of structures. Based on their purpose, certain size requirements are imposed on them. So, rafters, basement beams and interfloor floors, stair treads are usually made of wood of the second or third grade, having a thickness of about 50 mm, a width of 150 to 180 mm and a length of 4 to 6.5 meters.
As for the finishing of elements made of wood, the best option in most cases is a shalevka, which has a thickness of 7 to 19 mm, a thickness of wood in the range of 22-35 mm and different thicknesses of boards. Boards can be used as clean-edged, with a rectangular cross-section along the entire length, and with a sharp or blunt wane. Quite often, unedged boards can be used for this kind of purposes, which have a sufficient level of workmanship, but the cost of which is somewhat lower.
