The most common general-purpose steel bar grating spacing in North America: 19 bearing bars on ~1-3/16" centers with cross bars every 4".
In the name 19-W-4, the first number is the bearing bar spacing in sixteenths of an inch (19/16" (1-3/16") on center), W means welded, and 4 is the cross bar spacing in inches.
~1-3/16" bearing bar centers (19 bars per section)
Cross Bars
4" cross bar centers
Typical Use
General industrial platforms, walkways, and mezzanines
Load Profile
Balanced load capacity and open area for the widest range of foot-traffic and light-vehicle applications.
