Bonding steel frame?

[rocker]

I've been looking at some work in a little steel framed prefab bungalow (you know the type, corrugated tin jobbies). The frame seems to run through the entire house and is used for all the architraves round the doors etc, i.e. the frame is visible, just painted over. I'm not totally familliar with the construction of these buildings, but I'm assuming the steel frame goes into the foundations, so is this eligible for bonding? If so, how would you guys go about doing it?

Any help appreciated as always.

Assuming it is (electrically) continuous steel then only one main protective bond will be required, sized as usual.

You can, if you wish then link from the steel frame to other extraneous-conductive parts like gas and water supplies.

Hi IQ do you know how to actually bond to it? I'm really not sure about drilling structural steel, and even getting continuity is going to open it up to rust, surely?

Have a look at this catalogue: https://www.electriciansforums.net/attachments/erclamp-pdf.120203/

There's normally something in there to suit.
