Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other manmade structures. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects.

Each type is made from several components which often include:

• A base jack or plate which is a load-bearing base for the scaffold.
• The standard, the upright component with connector joins.
• The ledger, a horizontal brace.
• The transom, a horizontal cross-section load-bearing component which holds the batten, board, or decking unit.
• Brace diagonal and/or cross section bracing component.
• Batten or board decking component used to make the working platform.
• Coupler, a fitting used to join components together.
• Brackets, used to extend the width of working platforms.
