Load bar direction (span)
It is important to check the load bar direction (span) when ordering aluminium grating as it needs to be supported in a specific way. The load bars are the flat bars standing on their edge in which the grating is manufactured from.The supports need to be at 90° (perpendicular) to the load bar direction.
