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.
