Specifying overhead and coiling doors
Sectional overhead door systems (sometimes referred to as ‘panel doors’), as well as coiling (i.e. ‘rolling’) and high-speed door systems can be found on most commercial, industrial, and institutional buildings. Material options for these doors vary so much one regularly sees different thicknesses with steel, and aluminum in four finishes (i.e. mill, clear, coloured-anodized, and powder-coated). High-speed doors will be either fabric or rubber.
