General information of steel grating
Bearing bar - A flat bar withstanding the main load is in
consistent with the span direction .
bearing bar pitch - the distance center to center of the two
bearing bars.
Cross bar - the connecting bars , made from twisted bar ,round bar
or flat bar, which extend across the bearing bars .
Cross bar pitch - the distance center to center of the two adjacent
cross bars.
Length (span)- the maximum dimension of a grating panel ,measured
parallel to the bearing bar ,and in the same direction as the
baering bars .
Width - the maximum dimension of a grating panel ,perpandicular to
the bearing bars .and in the same direction as the cross bars.
