Decks

Decks are flat, horizontal surfaces used in a variety of contexts. In architecture, a deck is a raised outdoor platform connected to a building, designed for leisure, dining, or access to gardens. It usually consists of a structural frame of joists and beams, a surface made of boards, and a railing. Materials range from pressure-treated wood and tropical hardwoods to composite and vinyl products. Design considerations include load-bearing capacity, moisture management, weather resistance, and compliance with local building codes, as well as integration with stairs, railings, and built-in lighting. Maintenance requirements vary by material.

In card games and gaming culture, a deck refers to a complete set of playing cards used for play. A standard modern deck contains 52 cards in four suits, plus sometimes Jokers. There are numerous variations, including tarot decks, collectible or trading card game decks, and specialized decks tailored to particular games. Decks are shuffled and dealt according to game rules, and players may construct or modify decks in many games through rules such as deck-building.

In maritime use, a deck is a floor or platform that forms a discrete level of a ship. The main deck is typically the principal continuous surface, while other decks are mounted above or below. Decks must support occupants, equipment, and cargo, withstand weather and sea spray, and provide access via stairs or ladders and watertight hatches. Nautical terminology distinguishes decks such as foredeck, middeck, and weather deck.
