Definition
The flat boards that form the top and bottom surfaces of a pallet. Top deck boards provide the platform on which goods are placed, while bottom deck boards (also called bottom boards) provide stability and allow the pallet to be stored on flat surfaces. Deck board thickness, width, and spacing directly affect a pallet's load capacity and suitability for different applications.

Pallet
A flat transport structure, typically made of wood, that supports goods in a stable fashion while being lifted by a forklift, pallet jack, or other jacking device. Pallets are the foundation of modern material handling and logistics, enabling efficient storage, stacking, and transportation of goods. The most common pallet size in North America is the 48x40 inch GMA pallet.
Lead Board
The outermost deck board on each end of a pallet, running perpendicular to the stringers. Lead boards are critical structural components because they are the first point of contact when a pallet is pushed into racking or engaged by automated handling systems. Lead boards should be made from strong, defect-free lumber because damage to a lead board can compromise the entire pallet's integrity and cause handling problems.
Stringer
A continuous, longitudinal solid or notched board that connects and supports the deck boards of a pallet. Stringers are the structural backbone of stringer-style pallets, running the full length of the pallet and providing the framework that holds deck boards in place. Most standard 48x40 pallets use three stringers — two along the outer edges and one down the center.
Board Foot
A unit of lumber volume measurement equal to a board that is 1 inch thick, 12 inches wide, and 12 inches long (144 cubic inches). Board feet are the standard unit for measuring and pricing lumber in the pallet industry. The board footage of a pallet determines its lumber cost, and optimizing pallet designs to minimize board footage without sacrificing performance is a key cost reduction strategy.
