Swage Steel Grating/Press-locked Steel Bar Grating
Swage Steel Grating is popular for the manufacture of aluminum,
stainless steel and close mesh gratings. Cross bars are inserted
into pre-punched holes in the bearing bars and then hydraulically
deformed (or welded) to lock the bars in place.
Swage-Locked I-Bar Grating is the most widely used and provides the strength equal to a
rectangular bar of the same depth, but at far less weight and cost.
The I-bars are permanently locked to the cross rods (positioned
every 2" or 4") by a swaging process.
Swage-Locked Rectangular Bar Grating uses the swaging process to permanently lock the cross rods
(positioned every 2" or 4") to the rectangular bars.
