Classiko Roofing Sheet is lightweight but due to high-tensile long span sheets, it is the safest and strongest roof for modern building concepts. For an average roof area of 215M 2 [2,300 ft 2 ] the loading weight on the building is only 1 m.ton as compared to approximately 5m.tons when using traditional concrete tiles on the same area. With Classiko Roofing Sheets , the common risk of wall cracking and sinking will be greatly reduced.
