Fitting Blinds to Fabricated Metal Lintel

[topgazza]

So I have discovered I have metal lintels under the plasterboard in my window recess. I want to fit some roller blinds is it correct to drill through the fabricated, not solid steel, lintels with a small HSS drill and just use long self tapping screws to provide a decent hold for the blinds ?

Thanks

Your going to have masonary right ontop too.

Its plasterboard and a very thin skim of masonary, no more than a couple of mm. Then the pre fabricated lintel.

Yes hss bit Should do it, fixing will be very strong so you can use just one screw per fitting.

Thanks. I was fairly confident but always wise to check here. I could get away with wood screws but proper job is self tappers. Need 70mm to sure to allow for platerboard and skim before lintel. And of course drill a small hole and let the self drillers do their job

I was meaning ontop of the lintel. There's blocks ontop of my lintels so I'd probably drill an 8mm hole in the lintel then 6mm into the block above and fix with a red plug.

I Understand. This is recessed in the window space so is fitted underneath the lintel into metal. So I'll use some 1 1/4 self tappers
