Raker beams are angled, notched beams that support stadium riser units. They are used universally in outdoor stadiums and arenas and in many indoor arenas and performing-arts theaters.
Sizes can vary as required structurally and to match varying riser sections that they support. They typically are made 16 to 24 inches wide and are cast either upside down, on their side or upright, depending on the manufacturer’s preference.
Typically, three sides will have an “as cast” finish that results in a smooth, hard finish. The fourth side is troweled by the finishing crew to match the other sides as closely as possible.
