Roller shutter doors are the most popular and economic choice for goods doors. These will normally have galvanised laths and be hand operated by means of a chain. Options include electrical operation, coloured laths, Windlock guides and insulated laths, all of which incur additional cost. In general 0.6m (2ft) should be allowed above the door opening to allow space for the roller.
An alternative is the sectional overhead door, which uses hinged panels (with optional vision panels), these doors run on a track which protrudes into the building, usually horizontally, but which can be arranged to follow the internal roof line. Again, these can be both manually or electrically-operated.
