Stainless Steel Bar Grating
Stainless Steel Bar Grating is manufactured from alloy types 304, 304L, 316, or 316L and available in grating types "WS
" (welded stainless), "DTS
" (dovetail stainless pressure locked), and "SLS
" (swage locked stainless). Popular for highly corrosive environments and long-lasting architectural applications, stainless steel bar gratings are available with bearing bar spacing ranging from 19/16" (1-3/16") to 7/16" on center and with cross bars at 4" or 2" on center. Each product is available with standard plain or optional serrated or Algrip surfaces. Finish options are diverse and should be carefully considered.
Type "WS" Welded Stainless
Our strongest and most economical stainless product, type "WS
" gratings are manufactured by forge welding rectangular bearing bars and drawn cross bars. This welding process provides a positive fused intersection providing years of service under the most demanding conditions.
" stainless gratings are available in "19 space" (1-3/16"), "15 space" (15/16") and "11 space" (11/16")
bearing bar centers. Standard cross bar spacing is 4" on center and the optional 2" cross bar spacing is also available.
Type "DTS" Dovetail Pressure
Manufactured with a deep rectangular cross
bar, type "DTS
" dovetail stainless grating is commonly preferred for architectural applications. Sunscreens, grilles and infill panels are just some of the applications where this distinct "egg-crate" configuration is the ideal accent.
" stainless gratings are available with bearing bar spacings ranging from 19/16" (1-3/16") to 7/16" on center.

Type "SLS" Swage Locked Stainless
Hollow tube cross bars are hydraulically swaged into pre-punched holes in the bearing bars to make type “SLS
” swage locked stainless grating. This type of construction provides a secure bearing bar/cross bar intersection and products are available with bearing bar spacings ranging from 19/16" (1-3/16") to 7/16" on center.
This attractive grating, with the swaged cross bars slightly below the top surface of the grating, is very popular for “close-mesh”, ADA conforming applications. Consider “11 space” or “7 space” gratings for vault covers or entrance mats located in the public way.
Stainless Steel Finishes
As produced, stainless steel products typically display discoloration caused by the introduction of heat during welding, cutting, or grinding processes. If appearance is important to your application, consideration should be given to secondary cleaning or electro-polishing.
Products will display discoloration from welding, cutting, and grinding. Satisfactory for industrial or process applications where appearance is not a consideration.
A uniform, matte finish is achieved by abrasive blasting followed by passivation to remove manufacturing contaminants.

A bright, chrome-like appearance achieved by immersion in chemicals that clean and “polish” the base metal.
