What is a plywood?
Plywood is a sheet material that is manufactured from piles of the veneer of wood that are stuck together with piles that are adjacent layers and have the rotation of about 90 degrees of their wood grains. It is nothing more than an engineered wood from the family of manufactured boards which includes medium density fire board and particle board. All plywood basically have the same time of composition that is having to bind wood and also resin fibre sheets to help in the formation of a material that is composite. The alteration described is known as cross graining. The splitting tendency of the wood is reduced by it and it also it reduces contraction and expansion, providing god dimensional ability and makes a consistent power and strength of the wood. Smaller thin plywood and plywood of low quality may only have their piles which may be arranged 90 degrees from one another, though some plywood of good quality will be having steps which will be around 45 degrees
Types of plywood
There are various plywood types available in the market categorized into different types according to various criteria.
Softwood plywood- Cedar, pine and fir are the main constituents and this is one of the most used category for construction of buildings and various other activities. It has the property of varying in thickness and the distinct number of its piles. So this thinner plywood is more common than the other types of plywood found. Tropical plywood- Mixed species of tropical wood make up this cost efficient variety of plywood. It is considered generally superior to softwood plywood because of its better strength higher quality and also far better density.
Hardwood plywood is derived from angiosperm trees and is stronger than the former discussed type. And is looked up on due to the quality of durability and hardness. Hardwood plywood is the best type of plywood when it comes to strength and density and does is the most sought after type of plywood.
So these are the different types of plywood, among which hardwood plywood is most commonly used whenever the builder feels the need to have a plywood which is better in strength, density and the best endurance and the great quality of durability. So that is the reason why hardwood plywood is in so much demand.
