A plank of wood being used in the repair of a ship.

A plank is a piece of timber that is flat, elongated, and rectangular with parallel faces that are higher and longer than wide. Used primarily in carpentry, planks are critical in the construction of ships, houses, bridges, and many other structures.[1]

Usually made from sawed timber, planks are usually more than 1 12 in (38 mm) thick, and are generally wider than 2 12 in (64 mm). In the United States, planks can be any length and are generally a minimum of 2 in (51 mm) deep by 8 in (200 mm) wide, but planks that are 2 in (51 mm) by 10 in (250 mm) and 2 in (51 mm) by 12 in (300 mm) are more commonly stocked by lumber retailers. Planks are often used as a work surface on elevated scaffolding, and need to be wide enough to provide strength without breaking when walked on. The wood is categorized as a board if its width is less than 2 12 in (64 mm), and its thickness is less than 1 12 in (38 mm). also serve as supports to form shelves and tables.

The plank was the basis of maritime transport: wood floats on water from its inception, as abundant forests meant wooden logs could be easily obtained and processed, making planks the primary material in ship building. However, since the 20th century, wood has largely been supplanted in ship construction by Iron and Steel, due to the two metals being less costly and having greater durability than wood.[2]
