well, sort of.
I am putting a sloping covering (polycarb twin wall) over 4.5m of my side passage , it's a span of about 1m and I'm putting a 4x2 batten on the side wall of my garage as a joist, another 4x2 batten onto the concrete posts that make up the chainlink that is my boundary and 8 2x2 joists across to support the PC using joist hangers.
If the joists are 2" thick, what do i need in the wall - I'm thinking another 2" so 100mm frame fixings? Probably five along that length? I want to have enough in the brick but it's only single skinned and don't need 5 new coat hooks on the other side
Re drilling into the concrete fence posts..... I googled to find advice / what bit to use and was shame faced to find the best info was on a site called STW, where some chancer called theotherjonv had asked exactly that question SIX YEARS AGO

Any one else got a longer gap between thinking of a basic DIY project and finally getting wood to carry it out?
I'd go for 75mm into the brick i.e 125mm fixings through your 50mm timber.
A brick is 102.5mm thick and to want to get as much grip into it as you can without spalling the opposite face

I bought a tin of red paint to paint my back door in September 1997. The door is still green
Depends on era, 60-80mm. The imperials that my house is built from are nominally 68, but vary from 65-71.
That's a heck of a timber for a bit of light weight plastic. The 50mm into the brick should be more than adequate to hold the timber in place and whatever you fix the poly with is like as not to tear through that before the timber comes off the wall in the wind.
Just use decent anchors in the brick.

Nope, I usually go for some DIY as soon as I get wood.
reminds me off my father in law last year, i went to the builder merchant to buy 8 bricks we needed to brick up where an electric fan fire we had ripped out, i said to him before setting off what size bricks are they, i'll go measure them and he said 'dont be daft they only come in one size'.
so i went and got the 8 bricks, got back and was told "they aint the right size"
i said you said they only made bricks in 1 size, he said yeah they do metric and imperial, i replied aint that 2 siuzes then :0), he was adament, only one size
Drilling concrete fence posts is an arse, these should work though
Bricks have been metric 35 maybe 40 years, you may get ye olde heritage company that still make old imperial size. 102.5 mm you need good eyesight to see 0.5 of a mm
If your less than 50 mm you might burst the brick with plugs better using resin vials from toolstation
@dangeourbrain, the place I got the polycarb from suggest cross joists at 600mm spacing, but it does seem a lot, I'm thinking one each end and then four more would be enough (that's 5 spans then @ 900mm)??
@scaled, there's only three holes in the concrete posts and the other thread reckoned it should be ok, but they could be plan B
Always resin and threaded bar. Seemed has it.
In know someone who can tell you...
I'd be looking at 25x38mm battens every 400 (or 600) just because that's where battens should be.
I'd be using the same on the wall though.
Oh and to fix to the posts something like these of they'll fit

(ideally if recommend two bits of unistrut bolted/clamped together from either side of your fence post but it looks a bit of a pig)
