Anonymous users2024-01-23Balcony railings don't need to think about grounding protection! The reason is that it is an independent body, and it is not connected to a large area of metal, so the possibility of receiving lightning strikes is very small! It does not pose a threat to people.

Anonymous users2024-01-22？？Do you want the railing to be used as a lightning rod? Presumably the effect is not too good! No one has ever done that! I've also been doing renovations for several years!
Whether you need to do lightning protection grounding, you should look at the geographical location of the villa, whether there are tall buildings around, if there is and can protect it, you don't need to do it;If the villa area is located on higher ground, it is best to install grounding. Because lightning induction is the same as direct lightning, it is also a type of lightning disaster.
To be grounded welded.
Strictly speaking, the bay window belongs to the exterior wall, although the internal metal railing is not on the window, but it is very close to the window, and it must be equipotential connection and grounding, the simple way is to connect the two ends of the wall and the window, and then connect it to the steel bar in the wall together. >>>More
Yes. If there is no lightning rod on the roof.
According to the explanation of the provisions of the GB50057 lightning protection code, the part of the high-rise building that exceeds the radius of the rolling ball (30 meters for the first class, 45 meters for the second class, and 60 meters for the third class) may occur if the lightning strikes its side, especially the protruding sharp objects, wall corners, and edges. The external metal objects on the side of the high-rise building should be equitently connected with the lightning protection device, beyond the radius of the rolling ball and at the top end of the building height of 20%, and flash receivers should be set up in the corners, edges and prominent positions (balconies, viewing platforms, etc.). >>>More
The railings of many balconies are not connected by internal steel bars, which basically cannot be used as ground wires, and the heating pipes can also be made of metal.
