Will the lightning rod of the roof lead the current into the interior of the steel frame to cause electric shock?
The method of connecting the lightning rod to the wire made by the migrant workers in your country must be random and nonstandard. Your consideration is correct.
I remember the principle that I learned the lightning rod in elementary school, that is, to preach well, from top to bottom, until underground.The electrical knowledge of junior high school also can understand the principle of electric potential.
Bury ground wire with little resistance to the earth and connect directly to the lightning rod. Various standards, countries have standards.
