Which way does grating span?
Grating should always span in the direction of the bearing bars. The bearing bars are the primary load-carrying elements and must be oriented so that they rest on the supports. The cross bars, which connect the bearing bars, provide lateral stability but do not carry the primary load. Therefore, the span direction refers to the direction in which the bearing bars run across the supports.
