Birch plywood is commonly used as the substrate in engineered flooring due to its strength, durability, and waterproof properties. It is composed of several thin layers of birch veneer core glued together. It is well-suited for commercial vehicle flooring and trailer decking for its flexibility and ability to endure heavy foot traffic. [5]
