Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
The steel tube seems to be used only as a lightning rod and must be galvanized steel pipe. As for lightning belts... How expensive ah, it does not say, galvanized steel tube bending with large area, not fixed, and each tube about 2m, every 2m connection also can not afford ah. Feel even if there is excess steel pipe, it is better to buy round steel to cost-effective.
Other examples are not used, mainly because the price of steel pipe is more expensive than flat steel and round steel
Steel pipes can be used instead of flat steel or round steel, and some of the structures on the buildings are connected and grounded by using steel pipe handrails on the walls of their daughters.
