Anchor A device by which bar grating is attached to its supports.

Anchor A device by which bar grating is attached to its supports.

Band A flat bar welded to a side or end of a grating panel, or along the line of a cutout, and extending neither above or below the bearing bars.

Load-carrying Band—A band used in a cutout to transfer the load from unsupported bearing bars in the cutout to the supported bearing bars.

Trim Band—A band which carries no load, but is used chiefly to improve appearance and to protect open ends of bearing bars.

Bearing Bars Load-carrying bars extending in the direction of the grating span.

Bearing Bar Centers (spacing) The distance center to center of the bearing bars.

Carriers (Punched Plate) Flats or angles which are welded to the grating panel and nosing of a stair tread and are attached to a stair stringer to support the tread.

Clear Opening The distance between faces of bearing bars in a rectangular grating, or between a bent connecting bar and a bearing bar in a riveted grating.

Cross Rods or Cross Bars The connecting rods or bars which extend perpendicular across bearing bars. Where they intersect the bearing bars, they are welded, forged or mechanically locked to them.

Cross Rod or Cross Bar Centers (spacing) The distance center to center of the cross rods or 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.

End Gauge The distance from the centerline of the last cross rod to the end of the panel.

Finish The coating, usually paint or galvanizing, which is applied to the grating.

Grating An open grid assembly of metal bars in which the bearing bars, running in one direction, are spaced by rigid cross bars attached to them.

I-Bar An extruded aluminum bearing bar having a cross sectional  shape resembling the letter "I".

Length The dimension of a grating panel measured parallel to the bearing bars.

Nosing A special L-section member serving as the front or leading edge of a stair tread, or of grating at the head of a stair. Usually manufactured of checkered plate, cast iron or aluminum abrasive material.
