• Stage units are called risers or rostra.
  • They're modular and screw together to make almost any size or shape stage - straight, angular, curved, circular, tiered, or can be custom-made to specific measurements.
  • The standard riser size is 2.4m x 1.2m. They're also available in some fractions, eg 1.2m x 1.2m, 2.4m x 0.6m.
  • Heights are in increments of 300mm;- eg 0.3m, 0.6m, 0.9m, 1.2m, with some in-between sizes of 0.15m, 0.45m and 0.75m.
  • They are made of 70mm x 30mm timber with 17mm ply lids, and are collapsible for storage (see diagram).
  • One-tonne load limit per unit.
    The stage framework is normally covered in stage skirt (see 'drape' pages) attached by plastic capping called stripping. Stage steps are called treads. The stage surface is usually painted in matte black but any colour or effect can be done to order, or it can be covered in shoe-kid, a soft vinyl that comes in a variety of colours (good for runway modeling, etc).
