The Use of Plywood in Construction
Plywood has become one of the most popular building materials, thanks to its useful properties such as ability to withstand moisture and high strength. Despite being robust and versatile, plywood remains affordable and durable for small businesses. A quick glance at the different types of plywood will reveal their importance.
From kitchen cabinets, floorings, and walls to furniture: the entire construction industry revolves around plywood. The use of plywood will only continue to increase as the global market grows because of lack of affordable and reliable alternatives.
Use of Plywood in Construction Engineering
Plywood is considered to be the cheapest and the best alternative to wood for making furniture, cabinets, paneling and even in industrial applications. It is because plywood is strong and impact resistant to a certain extent and it is available in easily workable sheet form when compared to wood.

What is commercial plywood?
There are different grades of plywood. The commercial plywood is the standard plywood that you can access in any hardware store when you ask for plywood. The commercial plywood is usually a grade of plywood that is quite cheap because it is manufacturer out of veneers or slices of woods called the ply which is glued or bonded together under high pressure. The commercial plywood is also termed MR plywood where MR denotes moisture resistant. This means that the plywood can withstand a fair amount of dampness, humidity, and moisture. The commercial plywoods are made with different types of veneers that are popular in a particular geographical location. You have commercial plywood made of Rubber veneers in the south whereas, you have veneers made of eucalyptus in some other place.
Fancy plywood is much more expensive than ordinary commercial plywood. In general, the price of fancy/back veneer (outer veneer) is 2~6 times that of ordinary hardwood/back veneer (such as red hardwood veneer, Okoume veneer, red Canarium veneer, poplar paste) Face, pine veneer, etc.). In order to save costs, most customers only require single-sided plywood to face fancy veneers, while the other plywood needs to face ordinary hardwood veneers.
Fancy plywood features
Fancy plywood is used where the appearance of the plywood is most important. Therefore, fancy veneers should have good-looking textures and become top-level (Grade A). Fancy plywood is flat and smooth.
The fancy veneers can be plain slices, quarter slices or rotary cuts (eg, rotary cut fancy birch veneers). Usually, fancy wood is natural wood. However, artificial (artificial) fancy veneers (also known as engineered wood veneers) are also available. Artificial fancy veneers look similar to natural wood veneers but are much cheaper.
Unsaturated polyester resin decorative plywood, also known as polyester board, is based on ordinary plywood, pasted with a layer of decorative board, and then coated with an unsaturated polyester paint on the paper surface after curing. The product is beautiful, bright in color, with a variety of fine patterns and high transparency, thick coating, high hardness and wear resistance, has a certain water resistance, resistance to a variety of chemicals and pollution resistance, therefore, it has been widely used.
Its production process is roughly as follows:
Plywood substrate coating decorative paper drying or hot pressing coating unsaturated polyester resin drying trimming grading inspection finished products.
The plywood base material requires good quality, and the surface of the plywood should fully meet the decorative quality requirements.
