Different Types Of Wood

A discussion on different types of wood available and their special uses in different areas of carpentry.

Which wood would you choose? When attempting to complete a wood project you must be careful of your choice of wood. Numerous species take on different characteristics. All are composed of 60% cellulose and 28% lignin. These substances make up the fibrous and woody cell walls of plants and trees and are held together by cementing properties. The individual consistencies and colors are the elements remaining of about 12%. Other characteristics are due to the way that the wood is sawed and cured. There are hardwoods from deciduous trees and softwoods from coniferous trees.

There are two basic wood grades. Select lumber is excellent quality for use when appearance and finishing are important and common lumber that has defects used for construction and general-purpose projects. The grades of the select lumber are: B and Better grade, which has minute or no blemishes; C Select grade which has some minor defects such as small knots; D select grade that has larger imperfections, which can be concealed by paint. The grades of common lumber are No. 1 grade containing tight knots and few blemishes. No. 2 grade that has more and larger knots and blemishes. No. 3 grade that has loose knots, knotholes, and other flaws. No. 4 grade that is low quality and No. 5 grade where the appearance is not important. The following are species, their characteristics and best uses taken from Readers Digest.
