Birch plywood is a versatile material that has become increasingly popular over the years due to its unique properties, such as durability, strength, and flexibility. It is made by bonding together thin layers of birch veneer, using a specialized adhesive that creates a strong and stable panel. Birch plywood is widely used in various industries, from construction to furniture-making to interior design, due to its exceptional qualities.

One of the key features of birch plywood is its grading system, which enables users to identify the quality of the plywood at a glance. According to the current standards GOST 3916.1 – 2018 and DIN EN 636:2015-05, birch plywood is divided into five grades, each represented by a particular letter or number code. Understanding the grading system is essential when purchasing birch plywood, as it ensures that you select the right grade of plywood for your intended use.

• Elite, highest – E, A;
• The first one – 1, I, B;
• The second – 2, II, BB;
• Third – 3, III, CP;
• Fourth – 4, IV, C.

The Elite grade is the highest quality birch plywood available, with minimal defects and deviations from the standard. It is perfect for use in high-end furniture, interior design, and construction projects, where the highest standards of quality are required. This grade is characterized by its smooth surface, uniform color, and lack of knots or voids. Elite grade plywood is ideal for applications that require a high-quality, flawless appearance, such as high-end furniture, cabinets, and decorative wall paneling.

The First grade of birch plywood is suitable for a wide range of applications, such as furniture production, flooring, and wall panels. It has a slightly lower quality than the Elite grade, but it is still a high-quality product. This grade may have some slight defects, such as small knots, minor discolorations, and minor surface irregularities. First grade plywood is ideal for applications that require a high-quality appearance, but where some minor defects are acceptable.

The Second grade of birch plywood is suitable for use in applications where the appearance is not as important, such as packaging, crates, and pallets. This grade may have some defects, such as larger knots, small splits, or discolorations, but it is still a sturdy and reliable product. Second grade plywood is ideal for applications where strength and durability are more important than appearance.

The Third grade of birch plywood is suitable for use in applications where the plywood will not be visible, such as the construction of formwork for concrete. This grade may have defects such as large knots, splits, and other blemishes, but it is still a strong and durable product. Third grade plywood is ideal for applications where strength and durability are the primary considerations, and appearance is not important.

Finally, the Fourth grade of birch plywood is suitable for use in applications where the plywood will be used for temporary purposes only, such as hoardings, signs, and fences. This grade may have significant defects, such as large knots, cracks, and discolorations, but it is still a functional and cost-effective product. Fourth grade plywood is ideal for applications where appearance and strength are less important than cost-effectiveness.

Apart from the five grades of uncoated birch plywood, there are also other types of birch plywood available, such as Birch Wire Mesh Plywood (F/W) and Birch Film Faced Plywood (F/F). Birch Wire Mesh Plywood is a type of birch plywood that has a wire mesh pattern embedded in the surface, providing additional strength and durability. It is ideal for use in applications such as flooring, ramps, and scaffolding. Birch Film Faced Plywood is a type of birch plywood that has a thin film layer applied to the surface, providing additional protection against water and moisture. It is ideal for use in applications such as concrete formwork, where water resistance is essential.

In conclusion, birch plywood is an excellent material for a wide range of applications, from furniture-making to construction to packaging. Its unique properties make it a popular choice for various industries. By understanding the grading system of birch plywood and the different types available, you can select the right grade and type of plywood for your intended use, ensuring that your project is completed to the highest standards and that it will last for many years to come.
