In one connotation of the word, the term timber refers to wood that has yet to be harvested — meaning that it is still in the form of an undisturbed erect tree whose roots are seated in the ground.
Once the tree has been cut down and is removed from its root structure, the transformation begins into other processed forms of wood products.
A second connotation of the term timber relates to a form of wood which still retains its original bark. There are cases where it is desired to maintain the wood in as close to its original state and appearance as possible, for design aesthetics.
So timbers may also, in that case, retain more of the variations in size that reflect their growth patterns, rather than being sawn to specific dimensions. And yet there is still another connotation of the word timber that places it closer to lumber — and that is defining timber by its dimensional characteristics. One such definition considers timbers to have sizes that are no less than 5 inches, as contrasted with smaller sizes of sawn wood.
An example of where this might apply is in timber frame construction for use in timber frame homes , characterized by the use of these larger beams and posts which are referred to as timber. There are other uses of the term timber. It is often applied when referring to the boat building industry, where boat timbers is a common phrase for the material used in the construction of wooden boats, which includes hardwood such as teak.
Timbers may also go through additional processes to be creosoted or chemically treated to preserve their ability to survive environmental exposure and to prevent rot. A common use of these techniques is to produce wooden railroad ties or for external applications of woods in landscape timbers.
Plywood can be produced from either hardwood or softwood, and both types have advantages and disadvantages. Hardwood plywood typically has excellent strength and stiffness, making it ideal for demanding uses such as heavy-duty floor and wall structures.
Softwood plywood is used for construction and industrial purposes as well, although usually in less demanding situations than hardwood plywood. Although it varies depending on local timber markets, ply logs often fetch a value that is equal to or slightly higher than sawtimber.
Sawtimber, or sawlogs, refers to logs or trees that are large enough, and of a high enough quality, to be sawn into lumber. Just like with ply logs, when classifying trees for sawtimber, a logger or forester will look for:.
Once the trees are selected and cut down, they are taken to the mill and sawn into lumber. The waste products are converted into chips for fuel, or pulp for paper production.
Sawtimber products can be cut from both softwood and hardwood trees. So how does a mill turn a round log into square boards, while minimizing waste? The difference between the three is the resulting angle of the grain, with quartersawn being closer to 90 degrees, and riftsawn being closer to degrees.

Although overall value for sawtimber depends heavily on the tree quality, sawtimber products are usually valued higher than Chip-n-Saw, and lower than pine poles. Trees or logs that are too small to be turned into poles or sawtimber are instead processed by a method called Chip-n-Saw, or CNS. The milling process for CNS is very similar to the other products, although the end result is slightly different.
Logs are sent to the sawmill where the outer layer is ground away. Larger logs are slabbed and sawn to create 2x4s and other small dimension lumber. Smaller logs in the load are chipped for fuel or paper pulp.
Pulpwood can be produced from either hardwood or softwood. So how do wood chips get turned into pulp, and how does that pulp get turned into paper? There are a couple different ways. With mechanical pulping , machines are used to grind wood chips into pulp, creating a pulp that retains most of its lignin a natural glue that binds plant cellulose fibers.
Bamboo is a natural organic material. It is one of the most unique plants on earth. Bamboo is grown in abundance in many parts of the world, especially in tropical and subtropical regions. Most timber producing bamboos are from South Asia. The color of bamboo timber is pale yellow to almost gold. It is an industrial material also identified as the most promising building material.
Bamboo timber is an alternative to tropical hardwoods in recent years. It is available in many forms. Birch is a great craft-wood. It is an important source of hardwood timber.
Birch is of many types of like-yellow birch, white birch etc. Yellow birch is commonly used which is also known as gray birch, or swamp birch. It is light reddish brown color. Birch gives low natural luster. Cedar is a timber of high quality. It comes from several different trees known as cedars. Where both strength and appearance of the exposed wood beams are important, cedar is the only savior and perfect fit for this.
It is used in for-landscape, park, garden structure. Its moderate strength and softness make it unique. Cedar offers the advantage of the natural advantage. Basically, it is a workable material. Cherry timber is grown as a tree plantation timber.
Among different types of cherry timbers, black cherry timber is the largest of the native cherries and the only of commercial value. It is found throughout the Eastern United Nations. In cherry timber, the grain is generally straight.
