Installation Instructions

 

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.

Finish - The coating, commonly paint or galvanizing, which is applied to the grating.
Flush-Top Grating - A type of pressure-locked grating in which the cross bars and bearing bars are in the same plane relative to the top surface of the grating.

The steel grating must be installed with both ends being placed on supporting base like wide flange beam, stringer.
