The panel can be sized such that the parallel length of the straight pipe lines is 300 to 5000 mm, and the perpendicular span of the straight pipe lines is 100 to 4000 mm. The piping arrangement may have a hot-dip galvanized layer or a highly corrosion resistant galvanized layer formed or provided only on the outer surface of the piping arrangement. For example, the gap between adjacent pipes in the straight pipe lines is 100 to 300 mm. In addition, the straight pipe lines and the bend sections can be made from a single long pipe. The piping arrangement may be made from a steel pipe with a silicon content of less than 0.05 wt %, or not less than 0.15 wt % and not more than 0.20 wt %.
