What is plywood fir?
Plywood Company is a type of composite building material that is usually produced in leaves. It consists of thin layers of wood, also known as veneers or layers, hence the name plywood. In order to be considered a plywood fir, at least part of the layer must come from the tree tree. This often leads to plywood with firms or cores covered with birch trees or other wood, but which are still known as plywood. The plywood sheet veneers are glued together and placed so that the wooden grain of each leaf is at the right angle to the leaf adjacent to the leaf, leading to a greater overall strength.
From the scientific family of Pinaceae is a tree tree, which is a type driven, which means it is that it is Jeda and remains green throughout the year. There are between 48 and 55 different types of companies, including abies balsamea , which is Balsam fir, and abies braser , Fraser Fir. Although a similar appearance and well known, Douglas fir is not really a company, because it belongs to another family, pseudotsuga.
wood from the tree tree is not considered to be usable for the general building itself. Therefore, it is usually combined with other types of wood to create plywood that is strong and durable. It is also designed primarily for the use of internal use, because the company lacks any insect resistant or disease resistant as soon as it has been affected. Plywood fir is often used inside houses and for the construction of houses.
plywood is considered engineering wood because it is generally composed of several types of wood. This combination usually leads to a stronger finished product. When a dose of plywood is produced, it usually receives a mark based on a number of nodes, distribution and other defects in the finished product. Each side of the plywood can have a different mark - with the highest quality and D Jurej lower.
Typical size and degree of plywood can be described as 3/4 ac , which means it has three quarters of PALCE (approximately 19 mm) and one side is of high quality, while the other has a medium to low quality. Plywood with class D will also sometimes follow the letter X. In general, it is for use on the outside of the house or building and should be glued.
Specialized types of plywood of the company may include sea plywood, which is used in boat construction. This type is coated with resin and has a higher quality than those used in homes. Sea fir plywood often suffers from the problem of checks , which occurs when small cracks or hair lines appear in the wood due to weather exposure and natural expansion and wood contraction. For this reason, other forests such as meranti or kumume are often preferred to the company in boat building.
