Different Types Of Plywood And Its Machining Process

Wood veneers are glued together to form plywood. Thin sheets are used for making plywood. The width of the sheets will be approximately 0.2 mm to 3.2 mm. Moreover, the sheet’s grains are superimposed in the perpendicular direction. Different types of plywood have a different number of sheets. For example, when it comes to birch plywood type it has an unusual number of sheets. So on both surfaces, the direction of the grain will be the same. If you notice plywood sheets for sale, ensure to check thoroughly before buying.

Even the number of sheets is used for making conifer plywood type and for joining the sheets phenolic adhesive resin is used. This adhesive is resistant to extreme weather conditions. The colour of the conifer plywood is darker when compared with the veneering wood. Plywood’s properties are similar to wood.

Based on the manufacturing process the plywood has many advantages. Some of the main advantages are its strength, with the help of plywood you can form a rigid structure. Plywood are resistant to shock and dense. They are used for multiple purposes.

Different types of plywood sheets for sale:
Basic plywood type:
Plywoods are classified into three main categories. They are birch plywood, mixed plywood, and conifer plywood. Birch plywoods are used for applications which need strong and good quality plywood. Some of the applications of birch plywood are interior lining and special flooring. Mixed plywoods are used for multiple purposes. They are used as concrete moulds and also as basic boards. The quality of mixed plywood is similar to birch plywood. In combi plywood type both the surface is made up of birch plywood and the internal part is made up of both conifer and birch plywood.

The next type of mixed plywood is mirror image combi type plywood. In this type, the surface veneers are made up of birch and the internal part with alternative birch and conifer. Another type of mixed plywood is twin plywood. In this type, the surface is made up of birch plywood and the internal veneers are made up of conifer plywood. Conifer plywoods are used in the construction industry. Conifer plywoods are made up of spruce.

Special plywoods:
If the basic plywood is made for some special purpose then it is called special plywood. Special plywoods have standard dimensions and they are coated with different materials based on its purpose. Plywood coatings are resistant to chemicals, weather, shock and wear. It will also improve the friction property of the plywood. The edge of the plywood is protected using edging colour paint. The protecting edge colour paint will protect the plywood from moisture.

Flame retardant plywood:
The plywood is made resistant to fire by treating it with the flame retardant. The surface of this plywood type is treated at the factory. This plywood type is used for structural applications. The flame treatment will not affect the basic properties of the plywood.

Applications of plywood:
Plywoods are used for making wallboard, roof structure, subfloor board, wall lining, panelling for a half wall, and ceiling wall. Plywoods are suitable for interior lining also.
