When manufacturing rabbet roofing it is possible to change the sheet coating width from 220 to 880 mm, but in practice most people use 545 mm width.

The sheets are cramped by metal cramps or “clampers”. It means that metal sheet is not sticked through. Cramping cramps to the board zinked screws or nails are used. A minimal quantity of cramps is 5 pcs/m2. An average distance between cramps is 400 mm. If building roof is located in a windy place, a recommended distance between cramps is 300 mm.
