Sandrini Metalli SANDgraf

Standing seam sheets have always represented one of the most versatile and long-lasting traditional roofing systems.‎ The absence of holes and the particular type of junction make it the roofing system for excellence.‎ This particular type of roofing is used mainly for its characteristics of extreme safety, in critical contexts such as high mountains or where rainfall is abundant and often violent, both on the roof and on the facade.‎ We recommend the choice of this type of coverage for roofs with a slope 7%*.‎ We also recommend paying maximum attention to thermal expansion depending on the material.‎ Main benefits of standing seam SANDgraf are: - Simplicity of laying: through double seamin, that is, overlapping the edges of two sheets and folding them twice together; - Versatile use: from pitched roofs to complex constructions such as domes or large roof areas, thanks to the possibility of profiling on site; - High security: thanks to fixing without holes and the special jointing method; - Resistance to rust: there are no uncovered cutting points (if the installation is done properly); Sandrini Metalli can supply the necessary accessories for the installation of the system: fixed and sliding staples, snow stops, photovoltaic clamps, etc.‎
