Wind resistance of aluminum-magnesium-manganese alloy profiled roofing panels

- Aug 21, 2019-

As a traditional pressed metal sheet roof, its backward fixing method determines its wind resistance, such as the use of a screw-through fixed roof panel, the contact between the screw cap and the roof panel.The area is small. In the event of high winds, due to repeated positive and negative wind pressures, the roof panels create stress concentrations at the nail holes, causing tearing. Although the screws remain on the purlins, the roof panels have been blown away.

The roofing system adopted by K-HOME color steel YX65-420 lead magnesium-manganese alloy profiled board is fundamentally different from the traditional sheet metal construction in the fixing method. It is fixed by high-strength aluminum alloy fixing seat and purlin, and then the roof panel is stuck. Fix the seat on the plum head, and then use the electric sewing machine to lock the rib to the fixing seat. This fixing method does not need to penetrate the board surface, so the roof panel does not have any damage, and of course, there is no problem of stress concentration. .

This system has been tested for wind resistance in domestic authoritative testing institutions. In the repeated loading test of 7.0KPa, the test piece including the roof panel, the fixed seat and the screw is not damaged, which proves the superiority of the wind resistance performance of this roofing system. YX65-420 aluminum alloy hammered straight roof slab, the ribs are upright, so that the drainage section is almost unaffected by the ribs, effective drainage. The section is larger than the ordinary plate type, and the plate ribs are up to 65mm, which can guarantee the house. The panel is waterproof in the case of lateral tilting (curved roof), and it is more adaptable to the long roof with gentle slope.
