Why the span matters more than the area
A warehouse is sold in square meters but earns money in pallet spaces. A column in the middle of a span takes up not only its own spot but also the aisle for vehicles around it.
That’s why options should be compared by the price of a pallet space, not of a square meter. Often a building that costs 8% more gives 15% more storage spaces.
Where steel consumption grows
Up to 24 meters, steel consumption grows almost linearly. Beyond 30 meters the truss gets heavier faster: a 36-meter span in snow region III needs 20–25% more steel per square meter than a 24-meter one.
In snow regions IV–V the break-even point shifts toward smaller spans: the snow presses harder, and every meter of span costs more.
How to decide
Start with the layout of racks and aisles: it will suggest the column spacing. Then calculate two or three span options in the calculator and compare the price of a pallet space.
