Decking is a term that can be applied to numerous applications in
construction. It means building a structure with deck cover. These will usually
comprise a timber substructure with decking boards laid on top. The decking
boards can either be timber (usually pressure-treated) or be made of composite materials or
synthetic materials. Composite decking is a man-made building product made up of
mix of wood fibers, plastics and a small amount of bonding agents.
