Blockboard plywood is a type of engineered wood panel made by sandwiching a core of solid softwood strips between two layers of veneer or plywood sheets. The core strips are placed edge-to-edge and glued together, giving the board good strength and stability while remaining lightweight. Blockboard is ideal for making doors, tables, shelves, and partitions due to its resistance to bending and warping. It is especially preferred for furniture pieces with long spans.
