1) Bearing Bars - Load-carrying bars made from steel strip or slit sheets or from rolled or extruded aluminum and extending in the direction of the grating span.
2) Cross Bars - The connecting bars that extend perpendicularly across the bearing bars. Where cross bars intersect the bearing bars, they are welded, forged or mechanically locked to the bearing bars.
3) Grating - An open grid assembly of metal bars, in which the bearing bars running in one direction are spaced by rigid attachment to cross bars running perpendicular to them or by bent connecting bars extending between them.
