Good question. There is a lot of weight hanging up there and one turn to much on the screw can strip the thread and one day down it all may come. Having worked on steel framed apartments I was not impressed, the product may be o.k but it was the building crew that weren't up to it, mainly keen labourers.

Had a similar issue with mounting 60 inch display screens in a commercial building with steel framing partitions. Tek screws have little holding power on panel steel and proved to be next to useless. Ended up attaching the mount to a square piece of 5 ply that was glued to the gib and attached through to the steel studs with gravity toggles, worked a treat.

Cut a hole behind the TV and put in some timber, have done it before on a massive TV that was pretty heavy.

After the Canterbury earthquakes most of the steel framed homes flexed and bent and stayed that way.Wood framed flexed and bounced back and were easy repair.

I think #5 and #6 are right, no way would i trust screwing into lightweight steel framing. Personally i would probally go with ply, covering at least 2 studs width, but also put screws thru into both studs, rather than rely on just gluing to gib. And as #7 said, once bent if you get it wrong, there is no recovering from it with out replacement. What is other side of wall? could you fit bracing ply that side and bolt thru.

bridge a piece of 18mm melamine edge taped spanning 2 studs , then fix to that
+1 use these in a steel stud and won’t be coming out in a hurry. Best to use the tool to fit them
