Having never worked with steel in my life (apart from when I made a small hammer in CDT in school) I'm just trying to prepare myself for the worst and have a few questions:-
(I could probably have found out 3,4 & 5 by bothering my arse to search the net, but hey...)

How big?
Yes, but far more sensible to buy them cut to the right length.
Bingo!
Not sure yet, but say 10mm holes through 8mm RSC.
I'm just wondering if stock lengths will be cheaper than custom-cut lengths. What would you use to cut, say, the above?
Aye, cheers... :-) Found this site anyway, which might be useful for others...
Drill a ring of holes, then join them using a larger bit, or use a tank cutter type saw.
Yes. Hacksaw or angle grinder, go through both flanges and stop cutting 3/4" before the two cuts meet on the web, twist each end and the steel will shear.
J.B.
A normal drill with a decent drill bit will do this fine. If you have lots to do, then a magnetic clamp drill will make doing them accurately much quicker.
What do you have available to you? A 9" angle grinder will work well.
I was thinking Royal Horticultural Society.

With a drill bit soaked in oil. Start small and go slow and keep it well lubed in oil and you should cut it quite well. Well at least I have:)
Yes with a flame cutter, you can do it with an angle grinder use a 9 inch 'tho I have cut the off large steel section with a smaller one. Or you could use a hacksaw just apply a lot of elbow grease!..
Better still get the supplier to cut to length.
Pass on this one..

======Blacksmith's drills 14 to 20mm from:
======Yes, if you can get access to a mechanical hacksaw or bandsaw - both from:
=======Don't know!
=======Durbar plate - 1/4" thick steel or aluminium plate with anti-slip tread pattern
========Rectangular hollow section as far as I know, such as 1" square tube.
I prefer to buy them with holes pre-drilled, but up to about 1/2", I've simply used a HSS drill in a heavy duty hand-held electric drill. Take it slowly and lubricate well, preferably with a purpose-made drilling lubricant, but a 50/50 paraffin / oil mix works quite well. You do need a BIG tap wrench to hand tap 1/2" holes in them though.
The steel fabricators around the corner do it every day, so it must be. I wouldn't bother to try it myself as it is much easier to buy them cut to length.

Have these done by the supplier.
Rolled Steel Angle.

Yes, but I'd rather get someone else to do it

ITYM Durbar, which is steel plate made for flooring which has anti-slip pattern rolled on one side.
Depending on the context, rolled hollow section or rectangular hollow section.
============= Could that really be 'steel reinforced anchors'? - i.e. concrete blocks / foundations reinforced with steel. Just a thought....

Standard HSS drill. Not a blunt one. It'll do several holes with any electric drill. If you want to do many holes, the drill should be going under 500RPM, and you should use oil, or you'll burn out the drillbit.
(spray-on cooking oil is acceptible)
Be careful when close to break-through. If you are pushing too hard, then the bit can catch, which may shatter the bit (unlikely, but wear safety glasses) or more likely really hurt your wrists.
If you want to do many holes, then buy some 5mm drillbits, and use these to make a pilot hole. This will also let you locate the hole more accurately.
At the moment... a junior hacksaw?
Seriously, don't have an angle grinder but was considering buying one - will be useful for other stuff anyway. Hopefully I'll be able to get the stuff cut to length and pre-drilled relatively cheaply, but if I can get it significantly cheaper off-the-shelf then I'll just cut / drill it myself.
On a separate note, saw an RSJ nail gun on Grand Designs a while ago - don't
*really* need one BUT... ;-)Cheers for all the replies!

That would be SRA. Trust me, it is Rolled Steel Angle. RSC Rolled Steel Channel RSJ Rolled Steel Joist Baz
I had need to cut through two 200x8mm flitch plates. The first before it was installed, did that with a 9" angle grinder - easy enough. The second needed a short section trimmed flush to a surface after it was installed. I used an Axminster reciprocating saw with a long hacksaw blade on it. Also easy enough probably took a little longer but gave a more precise cut.
Hmm...
Even if you are going to buy an angle grinder, unless the price diff is huge (which it won't be), go for pre cut/drilled. Cutting an RSJ is not a good place to start learning to use an angle grinder, and starting with a 9" is a bad idea in any case.
