Center to Center Bearing Bar Spacing

Center to center bearing bar spacing is the of distance from the center of one bearing bar to the center of the next bearing bar.


Center to Center Cross Bar Spacing

Center to center cross bar spacing is the distance from the center of one cross bar to the center of next cross bar.



The bearing bars run parallel to the length or span of a standard grating panel and are responsible for the product's load bearing capabilities. The cross bars, which run parallel to the width of the span, are primarily responsible for holding the bearing bars together. However, they also play a factor in deflection characteristics, especially for concentrated loads which are not distributed across the span of the grating.




Welded bar grating is available with the following surfaces:

· Smooth - Standard surface.
· Serrated - Serrations are cut into the grating’s bearing bars surface


Bearing Bar Height

The bearing bar height, also known as bearing bar depth, is measured from the bottom of the bearing bar to the top.


Bearing Bar Thickness

The bearing bar thickness, also known as bearing bar width, is the measurement of distance between the left surface of the bearing bar to the right surface of the same bearing bar.



The span of the grating is the length of the grating between grating supports. In order to perform in accordance with its design loading characteristics, grating must be installed so that the bearing bars are parallel to the span. This is necessary because bearing bars are the primary elements which support the load applied to the grating.
