yes, as said above resin fixing gives a more precise and predictablly accurate positioning ime.
variations on this make are good, external being important i guess.
and for structural rsj like you mention something like this size of ..

1 tube but get 2 to be safe. use HDG studs not BZP. or if you are tight like me buy a 3m length of HDG threaded rod and cut to length. drill size is 2mm larger than whatever threaded rod you are using. make sure to galv spray the ends of the rods.

one tube of the 360 ml carton will be enough, just get a few extra nozzles as it can go off quick, with that in mind get prepared for 4 of holes at a time in order to not be panicking if youve got help lift the rsj on to the 4 bolts before they go hard as then there s a bit of movement iyswim, that is thye big difference to thunder blots , with them there no movement either way ,they have to be spoton drilled etc.

remember if using threaded bar , after cutting it, grind or file off the burrs and thread on and off a few times nut as a practice run, as it might be easier to do that then rather than after its in situ.

Thanks for all the feedback. Would a week be long enough to leave concrete to cure before drilling and using chemical anchor

If you are pouring new concrete, why not just incorporate the fixings into it using a jig to get bolt spacings correct. You then just lower the uprights onto the bolts and screw them down with the nuts......

that would be the best professional way yes ideal, youre right

but getting the positioning right is harder done like that and will be not so straight forward to lay the concrete ... if youre not experienced in practice than when the concrete is laid and line up the 2 stanchions on it in place move to fine tune to perfection iyswim .....then drill the concrete bolt holes through the steel holes in the perfect positions,pop in the bar and resin spot on....and it doesnt sound like its a big building
.....that is when done as a dIY type job.

couple days would be enough, just dont do them up that tight. come back a few weeks later and tighten them right up properly
