Timber is a type of wood which has been processed into beams and planks. It is also known as “lumber” in US and Canada. Basically, timber or Lumber is a wood or firewood of growing trees. Any wood capable of yielding a minimum dimensional size can be termed as a timber or lumber. It is a stage in the process of wood production. Timbers are used for the structural purpose. Those woods which are adapted for building purposes are timbers. Finished timber is supplied in standard sizes for the industry. Timber is used for building houses and making furniture.

Types of Timber and Lumber
Timber can be divided into two categories – hardwoods and softwoods. There are many types of timber under these two categories. They are-

*Bamboo
*Birch
*Cedar
*Cherry
*Cross-laminated
*Glulam
*Green timber
*Lime
*Mahogany
*Oak
*Pine
*Plywood
*Sapele wood
*Tulipwood
*Walnut
*Wood ash
*Spruce
*Fir

The followings are the advantages of Plywood:

1.An alternation of the grains is done inside plywood which is called cross-graining. It bears
importance for some reason which increases the facility of plywood. Such as
*Cross-graining in plywood helps to avoid the possibility to split while the edges are nailed.
*It increases the strength of the material.
*It helps to bind the grains more tightly.
*Unnecessary expansion and wood shrinkage are avoidable for cross-graining.
*Gives enriched spatial stability.
*Board consistency remains firm in all directions due to this.
2.Plywood has a reduced possibility to bend because odd numbers of plies are attached
maintaining balance inside plywood.
3.The stiffness of plywood has made it hard to bend and inflexible.
4.Plywood helps to contribute to the economy.
5.While solid wood is heavy, furniture made from plywood is comparatively lighter to transfer.
6.Plywood has ecological importance.

Plywood is a versatile material that can be used for a variety of applications. The thickness of plywood is determined by the number of layers, or plies, of wood veneer that is glued together. The more layers there are, the thicker the plywood. The most common thicknesses of plywood are 3/4 inch, 1/2 inch, and 1/4 inch.

The different types of Plywood.
Softwood Plywood
Hardwood Plywood
Tropical Plywood
Aircraft Plywood
Decorative Plywood
Flexible Plywood
Marine Plywood
Some of the uses of Plywood are:
1. Exterior Wall Sheathing
2. Interior Walls
3. Roofing and Flooring
4. Construction Material
5. Furniture
6. Cabinets
7. DIY Projects
8. Space Shipping and Aviation
9. Ship Construction Material
10. Surfaces Shaped Curved, U, or Folded
11. Interior Surface of the Skating Ground Material
12. Different Interior Games Stadium

Plywood is an engineered wood sheet material made up of fine layers or flimsy strands of wood veneers attached together placing wood grains 90 degrees to one another. It is one type of manufactured board which can be described as a mixture of Medium Density Fibreboard (MDF) and Chip Board (Particle Board). It is a complex material and attaches resin and fiber sheets of wood.
Plywood has become popular through this decade because it’s relatively low moisture content which makes various tasks easy to perform with this.
