Z40-Z275 Roofing Sheet

Brief Introduction：

Roof panels are panels that can directly withstand roof loads. After the roof panels are assembled on the sloping beams of the gable walls on the top floor of the house, the wing panels are overlapped to cover multiple individual box shaped roof panels without visible vertical joints, forming a well integrated sloping roof.
