The corrugated sheet is made "collaborante" with the casting by means of impressions capable of anchoring the casting itself, preventing lengthwide sliding and vertical separation. This is a draft table by way of indication. The possible presence of an electrically welded network laid before the casting is not considered. It is the planner's responsibility to check correctly each single case for what concerns the casting phase (sheet cribbing) and the working phase.
