What is a factory standard division?

The factory standard pitch gives mutually dependent values from when an entrance mat is divided in width and/or walking depth. Currently, an entrance mat is split when it exceeds 30kg, or when the walking depth exceeds 2000mm or the bar length exceeds 3000mm. The division is first made in depth (if feasible), as this division is later almost invisible. If this is not possible, it is divided evenly in width.
