Stainless Steel Bar Grating
Product Overview
Manufactured from alloy types 304, 304L, 316, and 316L, stainless steel gratings are ideal for sanitary or highly corrosive environments and architectural applications.
Available in three different methods of construction: type “WS” welded, type SLS” swage locked, and type “DTS” dovetail. Stainless steel gratings are produced with bearing bar spacings ranging from 19/16” (1-3/16”) to 7/16” on center with cross bars at 4” or 2” on center.
Finish options are diverse and should be carefully considered. For additional information, see Surface & Finish Options.
Types of Stainless Steel Bar Grating
Type “WS” Welded Stainless Steel Grating
Our strongest and most economical stainless product, type WS gratings are made by forge welding rectangular bearing bars and drawn cross bars. The welding process provides a positive fused intersection providing years of service under the most demanding conditions.
Type WS 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 with optional 2” spacing available.
Type “SLS” Swage Locked Stainless Steel Grating
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.
The swaged cross bars sit slightly below the top surface of the grating making this product very popular for “close mesh”, ADA conforming applications. 11 space and 7 space are ideal for vault covers or entrance mats located in the public way.
Type “DTS” Dovetail Pressure Locked Stainless Steel Grating
Manufactured with deep rectangular cross bars, type DTS dovetail stainless grating is commonly preferred for architectural applications. Sunscreens, grilles, and infill panels are just some applications where this distinct egg-crate configuration is the ideal accent.
Type DTS gratings are available with bearing bar spacings ranging from 19/16” to 7/16” on center. For architectural applications where increased bearing bar spacing is desired please contact our sales department.
