decking(redirected from Deck (building))
Also found in: Dictionary, Medical, Wikipedia.
a structural component that is installed on the supporting parts of a building or structure (such as walls, crossbars, beams, or girders). It is the foundation for building floors and roofs, bridge roadways, and operating platforms for equipment in industrial shops. The types of decking most widely used in modern construction are reinforced-concrete (cast slabs or panels or precast coffered or corrugated slabs or panels) and metal (made of steel sheets). Wooden decking (planks or logs) is used less frequently. Decking made of corrugated steel or aluminum sheet is suitable as a roofing material for industrial buildings; the use of such decking reduces the weight of structural members and the labor required for installation.
