What lumber is considered low grade

click fraud protection

To determine what sort of lumber, you need to divide the whip into 3 sections: middle, edging and vertex. Higher rates are usually observed with charcoal wood. This is due to the fact that there are no longer live knots on the sides of such logs, which cannot be said about the middle, where the largest number of different flaws are usually found. According to the assessment of the quality indicators of wood, wood is assigned one of four varieties.

An ordinary builder rarely has to deal with wood of the 1st grade, because it is usually used in the construction of ships, in aviation, of which the highest quality veneer is made. The second grade is usually used in the construction of barges, engineering and the construction of various buildings. The third grade is suitable only for railway sleepers and transfer bars for railways. It happens that such wood enters the furniture industry. The lowest quality of wood implies the cheapest boards from which various containers or furniture can be made.

The type of wood is determined depending on uniformity, strength, flaws and degree of moisture. When evaluating, attention is drawn to the worst part of the log.

Wood of low quality, for example, of the third grade, is used to create low-voltage cladding and flooring for installation. Visually, one can distinguish deep waves on it, signs of rot, fungal and other biological damage. The lowest grade option is used to create various containers and rough works during construction. A variety of defects can be detected in such wood. The main thing is that they do not violate the integrity of the material. Even when choosing draft material, it is worth avoiding rotten specimens, since it is pointless to cut it out, because a considerable area is infected with the fungus.

The crucial part of wood grade assessment is moisture measurement. There are special devices for this. However, you can cope with this task yourself. All you need is a planer. It is necessary to remove a couple of layers of chips, mash it in your hands, and if it breaks easily enough, then the wood can be considered dry. Excessive brittleness is observed when the material is overdried. In the course of work, many cracks may appear on it, especially if bolts and screws are screwed into the tree.
