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. Standard gratingsare also available with wider spacingsproviding even greater openarea, but should not bespecified withoutconsulting the manufacturer.

7 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.

Secondly,ssppaannindicates the overall finished length of thegrating panels (parallel to the bearing bars) asthey are supplied to the The overall dimension of the gratingpanel measured perpendicular to the bearing barspan is designated as the panel manufactured and stocked in 24" and36" nominal widths, grating panels can easily besupplied in a variety of widths to suit the needsof any application.

Additionally, custom widths can be shop fab-ricated to hold any specific SURFACE The excellent drainageand self-cleaning characteristics of plain surfacegrating make it suitable for the majority of appli-cations. In the presence of materials which couldcause the top surface of the bars to become slip-pery, the optional sseerrrraatteeddsurface should beconsidered. When serrated surfaces are specified,the bearing bar depth must be increased 1/4"greater than the sizes shown in the load tablesand selection guides to provide the equivalentstrength of non-serrated To enhance architectural appear-ance or to provide additional transverse stiffness,the open ends of the grating panels can be bbaanndd--eedd. This is achieved by welding a flatbar, similarin size to the bearing bars, to the cut ends of thegrating panel. Banding can reduce impact stressesby transferring loads to adjacent bars that are notdirectly subjected to service loads.

10 Trim bandingshould always be considered when the gratingpanels are designed to be removable on even aninfrequent basis. Additionally, banding shouldalways be specified when the ends of the bearingbars are unsupported or the grating is designedto service vehicular loads. Further bandingdescriptions and welding standards can be foundon page 17 of this Steel grating products are usuallyshipped with one of three standard finishes, baresteel, painted with one coat of the manufacturersred or black paint, or hot dip galvanized after fab-rication in accordance with ASTM Standard products are commonly supplied asmill finished, but are also available with optionalanodized finishes. Stainless steel products as pro-duced typically require secondary finishing suchas chemical cleaning, abrasive blasting or electro-polishing. All of our grating products can addi-tionally be supplied with specialty custom finishessuch as enamel or epoxy coatings.
