304 Stainless Steel Grating/304 Welded Bar Grating

304 Stainless Steel Grating/304 Welded Bar Grating

Stainless steel grating has been the standard industrial footwalk product for severe corrosive environments and has been a popular 

grating choice for many years. We manufacture stainless steel welded & swaged bar grating from type 304 and 316 stainless steel 

bar. Stainless steel grating is used at chemical plants, food processing facilities, oil and gas producers and is also used in many 

other commercial and architectural applications.

Stainless Steel Bar Grating is manufactured from alloy types 304, 304L, 316 and 316L and available in grating types "WS" (welded 

stainless grating), "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 surface and finish options are diverse and should be closely considered.

Welded Stainless Steel Grating

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.

 Dovetail Pressure Locked Stainless

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 building accent.

Type "DTS" stainless gratings are available with bearing bar spacings ranging from 19/16" (1-3/16") to 7/16" on center.

For applications where increased bearing bar spacing is desired, consider the specialty items presented in the Architectural 

Products section of this website.

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.
