Metal roofing system with standing seam interlock
Standing seam interlock is the core part of metal roofing system. On the basis of special profiled metal plate of standing seam design, this interlock can be applied mainly for long-span tight interlocking system on point support. No any perforated hole can be seen on the roofing, because the supporting is hidden under the plate. Roofing metal plates of occlusive seam are closely connected by special aluminum fixed support. The occlusion can be mechanically achieved in no need of manpower. And the occlusion can absorb the plate stress caused by heat expansion and contraction. The advantage of this occlusion is longitudinal over-length plate can be made unaffected by plate stress.
Suitable material for roofing plate: Aluminum-Magnesium-manganese alloy plate, Galvanized aluminum steel plate, Stainless steel roofing plate;
Suitable thickness for roofing plate material：0.6mm-1.2mm
Roofing standing seam height: 65mm
Roofing standing seam distance: 300-400mm (sector plate with reducer can be made, plate width depends on processing machinery)
