Standard warehousing column (Steel or RC) grids (Europe, Asia and almost the entire world) are:

6meter (centerlines)
with 12m and 24m spans of the roof trusses,

and 6m and 12 spans to any Mezzanines (flooring if required for offices usually front elevation) above Zero level.


6m is the standard size due to the way the racking is arranged within the warehousing, pallet size and forklift trucks.
