So we've recently had an extension and I'm looking at putting wide shelves up (thinking 600mm deep). It's plasterboard on brick, would frame fixings work at say 50mm long, also for something like a 3500mm span how often should I put brackets, every 500mm or so?

Cheers
 
Weight wise I'm not sure ( will be a display shelf for Lego).i only suggested 50 as it have some already :). Bracket wise I'm thinking at least 300 mm deep.
Something like this https://www.ebay.co.uk/itm/6-8-10-1...hash=item33dbd14051:m:mQ5o8-Z8AryArRLWG03yWEQ

No great weight then, not like books or records for example.

I’ve had good luck with hollow wall fixings and allowing the plasterboard to take the weight. If you’re going into the brick I’d agree with 70mm or more.
 
I've used dryline pro all over my house, the only place they failed was our coat hook (pulled the fixings out of the wall)

In that particular case I just used long frame fixings.

for shelves to display lego dryline pro will be more than enough :)
 
TBH my idea was basically to use frame fixings as those dryline pro operate (unsure if the dryline pro has a steel neck or not), also those things are quite expensive (relatively) compared to frame fixings.
 
Have look at gripit fixings, they also do an under cutting tool incase you're unfortunate enough to drill a hole where there's a lump of adhesive.

Just used them to hang various bits in my new build and they're solid.
 
Frame fixings are good but the Dryline pro ones allow you to tighten something up against them as they have a fat end like a normal plasterboard plug, whereas the end of frame fixings just tend to deform. Can't argue there's a price difference though.
 
I use both Dryline Pro and frame fixings to be honest. For things that are really heavy or need to support heavy weight, I tend to put Dryline pro on the outer and a frame fixing in the middle.
 
I use frame fixings for external walls, and hollow wall anchors for internals.
I note rawlplug have a new plasterboard fixing that looks kind of interesting.

I prefer anchoring into solid breeze if I can. The problem with all fixings that directly attach into/behind plasterboard is that plasterboard is inherently quite weak when you have done this. The fixing won't fail, but the surrounding area eventually will if the thing your hanging keeps getting shocked. Eg about the worst thing I have ever seen is a coat rack. Started with small fittings, went to toggles etc. Ended up with oversize the dryline pro. They all failed eventually, kids swinging on the coats almost whilst "taking" them off. 2 super cheap frame fixings into the breeze, been there ever since.

The only issue with going into breeze is that you of course leave a very difficult to fill hole. But the the dryline pro fix ended up with a piece of plasterboard gripfilled into place.

Its also worse if you have a newer house as they are using this lightweight thinner plasterboard as well. Its even less material you are suspending from.

I have put some shelves up using them, they are fantastic. Ive used them on a dot and dab wall as well, guy used them at work and since i tried them they are so much better than the ones with the course thread. I just didnt want to use them with a really wide shelf due to the depth of the shelf.
 
Recently mounted a 42" Plasma TV and arm mount to a woodframed plasterboard wall using Gripit fixings. Went slightly overkill with them, Used 6 of them, each apparently capable of holding the weight of the TV and mount itself. Also took the time to squirt some insulating foam into the 25mm holes too. They are quite large and if you locate a dab then you'd need the back cutting tool to clear some space out for the fixing.

Would have loved to go through into the brickwork on the other side, but for whatever reason the gap is a full 4" between the plasterboard and brick.
 
I used the small (15mm) gripits to mount 32" TV and extending wall mount. Had plasterboard with few inches of polystyrene and then a gap to the brick. Seems solid enough; would feel confident to mount a shelf with them (there is a YouTube video of tjem holding up a shelf with 100kg on... Snaptoggles did the best at 20kg more).

What type of video? Official or a DIYer? The problem with all these "will hold up to" is that they rate them in specific conditions in a lab that don't take into consideration the crap walls most of us have to put up with.
 
This is a good video showing the potential of some of the plasterboard fittings, including GripIts:
- obviously, mileage may vary depending on your own plasterboard.

Dryline Pro are my go-to for dot n' dab and GripIts are my go-to for plasterboard. Massively overkill for half the stuff I put up (even a toilet roll holder got the GripIt treatment), but they're decent and not had any issues.
