Bonding clamp for steelwork

[dg2908]

I need to bond an installation in a sectional building. The structure is made from several I-Beam arches joined by timber purlins so I need to bond each arch. I can't find these clamps mentioned much online, are they just called "I beam bonding clamps" or do I need to ask for something else?

There is one separate piece of steel in the building that supports the side of a gate - this is steel box section - how would people normally bond box section without drilling it?

Regarding the welding of structural as I recall you need to be fully competent in welding to structural work as a poor weld or even an incorrectly position weld can weaken the metal ... it also applies when cutting off unused sections with the old acetylene set-up ... if the metal heats up too much it can do alot of damage to its integrity.
Its sometimes the better option to drill but has others have pointed out - if in doubt get a Structural Engineer in.

The joys of demarcation, I would have to get one of the welders to do the job.

I drilled and tapped an 8mm hole in the steelwork of an industrial warehouse unit a few years ago.

The building was built in the 1940's as a munitions factory. Seeing as it was built to stand up to the Dorniers, Heinkels and Junkers it didn't worry me a great deal, to be truthful.

That’s perfectly safe Glenn, sat on a bench it’s doing nothing.

Sorry Dw my bad carry on mate!!

LOL ... joking aside if any 'I' steels are under so much stress you can't pop a <10mm hole in the centre third of the web then you really want to be getting out of the building, older builds are massively over compensated for their structural integrity but the new architech flamboyant designs that are cost cutting at every corner that you should think twice about.

Oh and those sweat shops that are built on a shoestring and always keep falling down because they add extra floors without assessment.

Which is all well and good until the next person comes along and just pops another 10mm hole through.
It is safer to forbid the practice.

One of the joys of working for multinationals is if I needed a structural engineer I only had to make a phone call.

Stud Welder Hire, all your equipment needs, one company | A-Plant... All your equipment needs, one company
Try one of these. Not difficult to use, though not the cheapest bit of kit to hire!

A bit on the expensive side for a few studs but a nice idea.

As I said I’d get one of the welders to attach 12mm bolts to the inside of the web where it’s out of harms way. These bolts would be positioned on the stanchions where there was to be cable ladders attached.
