Dear Mr Ghali.
Thanks for the additoinal informations.
i am also Concerned about the Lightining protection.
I want to know how i can calculate the maximum covereage of lighting arrestors in high rise buildings and in those builidings in which the
lightning protection device is provided at the highest point of the building like church towers.(as there is a maximum area any lightning
protection device can cover).
Thanks again in advance.
Hope to hearing from you soon.
