Best way to remove nail plate

[-Martin-]

Hello!
As the title suggests; what’s the smartest way to remove factory-installed nail plates? I'm moving some supports in the rafters and need some tips!

It's likely anchor nails or anchor screws there, and they are ribbed and of high quality to prevent breaking and are almost impossible to remove. Maybe by prying out the sheet so the heads come out, then putting the sheet back and using a pry bar. Otherwise, it's probably best to cut the sheet with a reciprocating saw at the joint between studs/rafters. The blade will probably pinch if you cut, as there is tension from above. And make sure nothing sinks down, especially thinking about the rafters.

You can remove factory-installed spikplåt with a crowbar and hammer but should not do so.

Factory-made roof trusses usually have pressed nail plates https://www.mitekab.se/product/spikplat-gnt-150s/

Why not?

I would assume that the truss is calculated and designed as it is to hold, have you calculated if the truss can be modified and if so, how?

Do you think you could answer the original question instead?

I did in post #3.
Tap in the crowbar with the hammer and break!

The smartest thing would be to calculate how the new truss should look and provide support where needed during the renovation. I believe that changes to load-bearing structures should be reported to the municipality. Then, I guess a crowbar is suitable for removing the pressed nail plate.

Hi
Let the spikplåt stay and notch the rule instead, given you're going to put something else in the same place.
Otherwise, specially grind a crowbar so you can grip the heads of the anchor nails. You can also split the spikplåt with an angle grinder, but I guess the fire risk might be high.
Feel free to provide more info as there are different techniques given the situation.

Brilliant! Short and concise.

As mentioned, these are punched plates that are factory-mounted. I'm considering proceeding with a solution using a slide hammer since the previous suggestions with a crowbar etc. cause too much damage to the studs.
