300 series Stainless Steel Bar Grating - RQL-M20

Stainless Steel Bar Grating is manufactured from alloy types 304, 304L, 316 and 316L and available in grating types welded stainless grating, dovetail stainless pressure locked and 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.

Our strongest and most economical stainless product, type 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.
Type 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 Dovetail Pressure Locked Stainless

Manufactured with a deep rectangular cross bar, type 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 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.

Type Swage Locked Stainless

Hollow tube cross bars are hydraulically swaged into pre-punched holes in the bearing bars to make type 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.
