Type "SL" Swage Locked Steel Grating
Type "SL" steel gratings are manufactured by inserting hollow tube cross bars into pre-punched holes in the bearing bars and swaging the cross bars forming a positive mechanical connection. The cross bars are recessed below the top surface of the bearing bars providing a uniform and attractive architectural appearance. Swage locking is a particularly efficient process for the production of close mesh gratings. Type 7-SL-4 with 3/16" thick bearing bars provides a net 1/4" clear opening between the bearing bars. This narrow opening is often preferred in public areas where concerns of drainage and the presence of high heeled shoes converge.
SWAGED PRESSURE LOCKED GRATINGS:
Pressure Locked Gratings manufactured by swaged are designated by the profile "PS." Swaged gratings are assembled by inserting hollow tube cross bars into pre-punched holes in the bearing bars and then swaging the cross bars (similar to the aluminum gratings). This permanently locks the entire cross bar/bearing bar intersection within the interior of the bearing bar.
