What is Plywood?
Plywood is a forest product that is widely used in the construction industry. Its water resistance and high strength are important for this sector. It is mainly used for the preparation of concrete formwork. It is a very suitable material for plasterless mold systems, which is also called gross mold.
Plywood is a panel consisting of layers of wood. It is a material that is lightweight, although it has very good mechanical strength. The number of layers is usually generated in such a way that it is an odd number. The outer layers are usually parallel to the long dimension of the panel. Successive layers are glued so that they are perpendicular to each other. This form of production is a structure that resists the shock effects that will occur with vibration, which increases resistance.
Today, Plywoods, the use of which is increasingly becoming a formwork material, have replaced traditional wooden formwork for receiving gross concrete. As you know, Plywoods are divided into film-faced and filmless.
Contrary to what is known, the difference between them is not related to durability but only affects the concrete surface. It is correct to use film materials on surfaces that will not be plastered, and it allows you to get shiny gross concrete. On the surfaces to be plastered, it is necessary to use filmless plywoods. The concrete surface obtained in filmless materials is again gross, but not glossy. Thanks to this feature, it allows plastering.
You may encounter additional costs later on due to not using the right material in the right place. Even though plastering will be done, due to the use of film material, some chemicals will have to bear an additional cost again.
As a result, it is suitable to use film materials to create surfaces that will not be plastered, and non-glossy and plastered surfaces without film are used where desired.

Plywood differs from MDF, high-density fiberboard (HDF), block, and particleboard. Others are cheap materials and their durability cannot be compared to Birch Plywood varieties.

Machinability of Plywood
When driving a screw on the edge of the MDF, the soft tissue is easily separated. When the countersink drill bit is not used, it can be inserted before the head of the screw sinks, or it can push the chips. Conversely, the diagonal parting of plywood slightly reduces the tendency to split when nailed at the edges. Plywood holds nails. It does not dissipate.
MDF is widely used in affordable, low-end furniture parts. Due to the non-directional grain structure of MDF, it is ideal for cutting, processing, and drilling without chipping or shredding.
The smooth surface of MDF makes it ideal for simple interior design parts to be painted, while plywood adds some durability to parts that need to be stronger. Both can be relatively easy for experienced DIYs to use and are found in affordable furniture products.
Machinability of Plywood
- The Construction Stage of Plywood
- The felled tree logs are soaked.
- The bark and other materials on the logs are peeled off and the tree is uncovered.
- A cutting plan is made by measuring the logs before they are cut.
- Logs cut to the calculated extent are sent to the stripping machine.
- With the help of special machines, layers are created by peeling thinly by blades parallel to the log.
- The cut layers are left to dry.
- The layers are placed so that the fiber directions are perpendicular to each other. There is always an odd number of layers on the panel so
- that the fiber direction of the lower and upper surface layers is the same.
- The layers combined with glue are sent to pressing.
- The glued and superimposed layers are pressed according to the thickness requirement.
- The panels are cut to the desired sizes.
- The panels are sanded on top. Palletized sheets are made suitable for transportation and storage conditions.
- It's light.
- The wood fibers that make up the layers are durable materials as they are combined in different directions (90 degrees to each other). It
- doesn't break easily.
- It can be produced in desired sizes with thicknesses of 6-30 mm.
- It is widely used in many sectors.
- It is resistant to cracking.
- Screw holding is high.
- It is easy to process and environmentally friendly.
- It's economical.
- Plywood surface can be polished. Paintable.
- It has a high resistance to water.
- It is an environmentally friendly product.
