Band – A flat bar welded to the end of a grating panel, or along the side of a cutout, and extending neither above nor below the bearing bars.
Load Carrying Band: A band used to transfer load between bearing bars.
Trim Band: A band which carries no load, used primarily for appearance and closing open ends.
Bearing Bars – Load carrying main elements made from steel, aluminum, or stainless steel, extending in the direction of the grating span.
Bearing Bar Centers – The distance center-to-center of the bearing bars.
Carriers – Flats or angles which are welded to the grating panel and nosing of a stair tread and are bolted to a stair stringer to support the tread.
Clear Opening – The distance between faces of bearing bars in rectangular gratings, or between a bent connecting bar and a bearing bar in a riveted grating.
Cross Bars – The connecting bars which extend across the bearing bars, usually perpendicular to them. They may be bent into a corrugated or sinuous pattern and, where they intersect the bearing bars, are welded, forged or mechanically locked to them.
Cross Bar Centers – The distance center-to-center of the cross bars.
Curved Cut – A cutout following a curved pattern.
Cutout – An area of grating removed to clear an obstruction or to permit pipes, ducts, columns, etc. to pass through the grating.
Electro-Forged – A process of combining hydraulic pressure and heat fusion to forge bearing bars and cross bars into a panel grid.
