It is a sheet which is manufactured by binding together thin layers of wood veneers. These layers are also known as plies; hence the name plywood. It is not a normal or naturally-available product, but is a type of engineered wood. The face veneers on a plywood panel are of a higher grade as compared to the core veneers. Increasing the space between the outer layers (where the bending stress is the most) is the major function of the core layers. It makes the thicker panels stronger. Tension and compression cause bending stress on these outermost layers, where the stress is maximum. But the plywood is engineered in a way that it handles all the stress easily. Even the very thin plywood panels deliver the best of the results.
What are the types of plywood?
The plywood family is a large one as it exists in various types. The various types of plywood are different from each other in terms of materials. For example, softwood plywood which is mostly brought into construction and commercial purposes is made up of cedar, spruce, pine, fir, etc. Hardwood plywood is manufactured from angiosperm trees and is used for high end purposes like strong floor structures. Tropical, aircraft, decorative, flexible and marine are some of the popular types of plywood used in different industries and purposes ranging from light to heavy duty. Basically, there is plywood designed to meet the needs of every industry as per the demands.
The Pros and Cons of Plywood
It is one of the strongest products used in various industries. It is very popular in the business of construction. The strength that it provides is trustworthy and hence it is used in the construction of buildings, houses, offices, schools, etc. So many lives are dependent on it. But at the same time, every coin has two sides. The disadvantages of plywood cannot be neglected as well. The plywood material is porous due to the layering. It is susceptible to damage by water if exposed for a large period of time. So, proper precautions are advised and it must be kept away from moisture. But owing to the low cost and the strength that it provides in this cost, it is always a smart thing to go for it but surely with attention and full precautions.
Some plywood facts
- The outer layers are made out of expensive timber and hence give a good looking texture to it. But actually, the inner layers are manufactured out of cheap wood. Now this is a piece of information which shows that not everything that meets the eyes is true.
- If your budget doesn’t allow the use of solid timber, then plywood comes to help. But plywood has its own shortcomings, which usually do come with low prices. Its edges are not really attractive and lessen the style quotient. But if it is okay with you, then don’t mind buying it.
- The plywood is not a modern product, but its roots go back to the ancient Chinese and Egyptian civilizations.
