Which deck type uses timber planks with wide face of the plank in the vertical position?

• A. Plan deck
• B. Nail laminated deck
• C. Stress laminated
• D. Wearing surface

Answer: (B)

Plank orientation is the key idea. In a nail-laminated deck, timber boards are installed on edge so that the wide face of each plank is in a vertical position. This creates a deck composed of narrow slats arranged side by side, with the broad side standing upright. That edge-on attachment is what sets nail-laminated decks apart from others, where boards are laid flat to form a solid horizontal surface (plan deck) or where the deck surface is created by laminated veneers bonded with glue and plates (stress-laminated). The description given—wide face vertical—fits the nail-laminated approach precisely.
