1. WHAT IS PROFILE 3? Profile 3 or Profile 130/35 is a profile with small pitch and low overall depth . This profile is popular in Japan and Korea. Profile 3 with pitch of corrugation is 130 mm and overall depth is 35 mm (without thickness of sheet) (see in below photo).
2. WHAT IS PROFILE 7? Profile 7 or Profile 177/51 has a very broad appeal. This profile is most popular in the world which is widely used in residential building, agriculture and industrial application. Profile 7 with pitch of corrugation is 177 mm and overall depth is 51 mm (without thickness of sheet) (see in below photo). DURAGREEN Profile 7 is designed for roofs of 5° slant and over. It is a high strength fibre cement sheet with variety in length and width and thickness that is easy to choose for your roofs and projects.
The reason for the distinction between profile 7 and profile 3 is due to the difference in pitch of corrugation and overall depth. Profile 7 (177/51) is with longer pitch and higher depth than Profile 3 (130/35).
