Birch plywood is a type of engineered wood made from thin layers of Birch wood veneer that are glued together in alternating directions. The WG 1300 x 3030 18mm specification refers to a single sheet of birch plywood that measures 1300 millimetres in width, 3030 millimetres in length, and 18 millimetres in thickness.

The “WG” in the specification stands for “Whole Grain,” which means that the grain pattern of the Birch veneer runs continuously across the full width of the sheet, creating a consistent and uniform appearance.

Birch plywood is known for its strength, durability, and resistance to warping and cracking. It is commonly used in construction and woodworking projects that require large, sturdy panels of plywood. Birch plywood is often used in furniture-making, cabinetry, flooring, and structural applications due to its strength, stability, and attractive appearance. The larger size of the WG 1300 x 3030 18mm sheet makes it suitable for larger projects and applications that require a larger surface area of plywood.
