ABSTRACT:
This invention relates to corrugated roofing sheets for building, made of a mixture of cement and inert materials, reinforced with synthetic fibers in fibrillated mesh form, characterized by having a rough outer surface due to the presence of surface granular material. The granular material is applied to the sheets during their finishing but before the cement has started to set, by simply strewing it over the sheet surface.
