Wind resistance
A test rig was set up with SkyProof roofing sheets installed on supports with a clear span of 1200mm. The panels were made of mill finish aluminum alloy 5754 with an actual thickness of 0.66mm. During the test, both positive and negative pressures were applied to the surface of the metal roofing using testing equipment. These simulated pressures represent the wind loads that would be expected to act on the roof during extreme weather events. During the course of the test, the deformation and structural behavior of the metal roofing were monitored and recorded.
Wind Uplift Test According to ASTM E1592 Standard
The ASTM E1592 test assesses the structural resistance of metal roofs in terms of deformation, bending, distortion, and potential component failure. The SkyProof roofing sheet endured 13 loadings with increasing pressure during the test before ultimately failing at 7230 Pa (approximately 737 kg/m²). This is an exceptional value for this type of roofing and with the fastening spacing of 1,2 metres unprecedented in similar products. The SkyProof roofing sheet has been tested for wind resistance in accordance with the technical standards ASTM E1592, entitled ‘Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference.’ This standard defines the test method for evaluating the structural resistance of sheet metal roofing and siding systems under uniform static air pressure difference. The test was carried out at an independent accredited laboratory.
