1. What is Radiata Pine Plywood?

Radiata Pine Plywood is a type of engineered wood made from thin layers of Radiata Pine veneer. These layers, or plies, are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. This cross-graining technique enhances the strength and stability of the plywood, making it resistant to cracking, shrinkage, and warping.
