CROSS GRAIN

When a board of wood is cut so that the growth lines in the wood are diagonal to the long edge of the board, it is called cross grain. Plywood is a common type of cross grain wood that is often used in kitchen cabinetry construction. Interestingly, cross grain wood is known for its strength and durability compared to solid wood. Solid wood tends to expand and contract based on environmental factors such as temperature and humidity, even after painting or finishing. This can result in changes in shape and size, weakening joints and leading to splitting and cracking. Cross grain wood, on the other hand, is less affected by moisture fluctuations and temperature changes, leading to fewer structural changes. This is why plywood is often used in the construction of cabinet frames and substructures.
