The common thickness of roof and wall is 0.4~1.6 mm; Thickness of 2~3 mm or more when used for load-bearing floor or silos. The wave height generally varies from 10 to 200 mm. When not reinforced, the height to thickness ratio should be controlled within 200. When the roof slab with long length is used, the slope can be 2~5%, and the deflection shall not exceed L /300(L is the calculated span). See figure for some waveforms currently used in buildings
