Lightning protection
Thread Content
Today, on the roof of the pharmaceutical manufacturing facility, I saw many cubic blocks made of cement, arranged in rows and columns; each of these blocks was approximately 100*100*100 mm in size； What is this? Is it used for lightning protection?
Are the cement blocks fixed or movable? It is recommended to provide a picture
Are there rebar on the cement connected to form a line? Is it a lightning protection pier?
The function of the rebar at the upper part of the parapet wall is to provide a cap. One purpose of this rebar is to ensure a stable and secure connection, thereby helping the parapet wall to remain integral as a single unit; another purpose is to enhance the durability of the wall under conditions of exposure to sunlight and rain over time, as well as extreme temperatures in winter and summer
