  • Patent number: 10400455
    Abstract: A metal roofing member 1 is disposed side by side with another metal roofing member on a roof base. The metal roofing member 1 has a box-shaped front substrate 10 made of a metal sheet, a rear substrate 11 disposed on the rear side of the front substrate 10, so as to cover an opening of the front substrate 10, and a core material 12 made from a foam resin and filled in between the front substrate 10 and the rear substrate 11. The front substrate 10 results from forming the metal sheet into a box shape. The front substrate 10 has a side wall portion that is continuous in the circumferential direction and is formed by performing drawing or bulging processing on the metal sheet. The front substrate 10 has a height of 4 mm to 8 mm.
