Plywood is one of the most versatile components used in woodwork. While it has roots in the ancient Egyptian empire, the version we encounter is relatively modern. In modern plywood making, numerous steps are involved. While there are standard steps followed, the best plywood manufacturers have the ability to make unique plywood types, as plywood also has artistic value. Being a highly versatile material, we can find it everywhere. However, there is no one-size-fits-all solution for plywood applications. In this blog, we will learn about different plywood grades and their applications.
Why Plywood is Graded?
Plywood is graded as there are many manufacturing variables involved in its making. The strength of the veneer, moisture content, its resilience to impact, type of adhesive, layering techniques, and variations in manufacturing steps create a world of difference in two distinct plywood types. Moreover, it has aesthetic value in many applications. Therefore, grading plywood helps in deciding what type of manufacturing approach is adopted by the best plywood manufacturers. The plywood is graded by judging its appearance and also its moisture resistance capacity.
Different Plywood Grades
A Grade: This is the highest quality of plywood, both in terms of strength and visual appeal. It has no flaws like cracks, knots, or blemishes on its face and back veneers. Gurjan, Birch, or Eucalyptus are hardwood trees used in this plywood grade. Its applications are in high-end interior furniture like cabinets in living rooms, wall panels, modular kitchens, TV cabinets, mandir cabinets, and outdoor furniture in open cafes.
B Grade: In b grade, there are slight imperfections that can be ignored and used in similar applications as A grade but more affordable. The quality and durability of the b grade are excellent. Extracted from Okoume trees, these are used in bookshelves, countertops, room dividers, accent walls, etc.
C Grade: C grade plywood has larger imperfections and is therefore not used for aesthetic purposes. Made from softwood pine, fir, or cedar trees, these plywood types are used in areas of hidden regions of the architecture like roof sheaths, and general construction works.
D Grade: This plywood has the most visible knots, splits, and blemishes. It is only used for its strength and low cost. These are used in construction works like concrete formwork, sheathing, and also in material packaging. Shuttering plywood is one great example of d grade plywood with no aesthetic value but is vital for its resistance to heat and moisture.
Special Plywood Grades
Apart from appearance, there is another grading method in plywood where it is graded according to its moisture resistance capacity, fire resistance and
Moisture Resistant (MR) Grade: Moderate moisture resistance. Used in dry interiors like lower kitchen cabinets, furniture, wardrobes, bookshelves.
Boiling Water Resistant (BWR) Grade: Great resistance to water as it is tested with boiling water. Used in marines as flooring, decks, and patios, and also in coastal areas for woodwork.
Boiling Water Proof (BWP) Grade: Best resistance to water. Suitable for swimming pool enclosures, outdoor furniture, saunas, bathroom panels, and dressing cabinets.
