8 Typically manufactured from mild carbonsteel, 6000 series aluminum and 300 series stain-less steels, bar gratings are also available in spe-cialty metal alloys to suit nearly any BARS The vertically positioned barsare designated as the bbeeaarriinngg barsrange in size from 3/4" x 1/8" for light pedestri-an traffic to 7" x 1/2" for extreme vehicularloads. Typically, the spacing of the bearing barsis indicated in sixteenths of an inch, measuredfrom the center of one bar to the center of theadjacent bar. This center-to-center or oonn cceenntteerrspacing ranges from 7/16" to 19/16" (1-3/16") onstandard grating products.

Heavy Dutygrating products are commonly manufac-tured with bearing bar spacings rangingfrom 15/16" to 38/16" (2-3/8") on BARS The bars used to securethe position of the bearing bars are com-monly designated as the ccrroossss Crossbar profiles vary according to the method ofassembly and material selected. As withbearing bars, cross bar spacing is measuredas oonn cceenntteerr spacing. The customary crossbar spacing is 4" on center.
