Abstract
Roofing is a part which is act as shelter for a house. There are many type of roofing such as tile roof, thatched roof, fiberglass roof and metal roof. For this project, to study about mechanical properties of Aluminum-Zinc, Alu-Zn sheet metal roof and Galvanized Iron, GI sheet metal for roofing system. Specimen for tensile testing prepared according to ASTM E8 with dimension of 165 mm × 19 mm × 0.3 mm in dog bone shape. For fatigue testing were prepared according to ASTM E467 with dimension of 117 mm × 26 mm × 0.3 mm in dog bone shape. For the tensile testing, mean value show that Alu-Zn specimen is higher compare to GI specimen by 347.46 MPa or 53.81%. This condition appear due to Martensite phase occur in Alu-zn specimen, from 600 °C. Meanwhile appear in GI specimen is Bainite phase when quench at room temperature from 450 °C. Fatigue testing showed cycle count of 5 cycles is the limit for Alu-Zn specimen with force applied is 14.187 MPa. At this stage, phase changes occur from elastic to plastic deformation. On the other hand, GI specimen also showed cycle count of 5 cycles is the limit with force applied is 6.959 MPa. On the top phase changes, factor that influence different force applied by 50.98% to Alu-Zn specimen and GI specimen in fatigue testing is bonding. Alu-Zn specimen consists of covalent and metallic bond, whereas GI specimen consists of covalent bond only. Hence, this project provides a clear mechanical property of Alu-Zn and GI specimen. This study has identified that Alu-Zn show higher tensile strength by 347.46 MPa. Fatigue testing show cycle limit at 5 cycles with force applied is 14.187 MPa.
