aerial pole will be made of ally, so no it wont rust, if its chrome its more than likely one of the wardrobe poles or towel rails, not good enough for
coolant in my eyes. 
or theres that chrome water pipe like you use in showers etc i suppose that would work, you'd maybe want to flare the edge to keep your rubber
hozes on.

the aerial pole at B&Q doesnt say alloy on it it I think? just says chrome plated metal
I have what seems the same chrome tubing but its in the metal section so presume its steel which I dont htink I should use

Yes lots of production cars use steel pipe only problem is corosion from the outside due to road salt. The inside is well protected by
antifreeze/coolant.
Exhaust pipe works just fine -- at least one of my racing imps was plumbed up using new old stock exhaust pipe -- mainly ISTR early 60s Hillman Minx
tail pipe and a Morris Oxfords exhaust..

Interesting that you are concerned about using iron / steel in a cooling system 
Most blocks until recently were made of cast iron / steel.
Rust needs the presence of moisture and oxygen to form so within a relatively closed cooling system there will be a small degree of rust formation
until the free oxygen dissolved in the coolant has been used up, after that no further rust will form.
Also modern anti freeze solutions contain rust inhibitors.
If I found a pipe I liked the look of, I would use it and just keep an eye on it initially.

The stuff I used from B&Q was deffo aluminium, very light, cut dead easy, able to bend with bare hands and a knee (25mm dia).
They may have changed the spec now, but they had two sorts, a straight length and a one with 2 x 45 degree bends in it, about a year ago.

I've never seen a chrome plated steel aerial pole, they are always alloy for the lighest weight IME.

I personally wouldnt use a steel pipe if there's no other steel / iron in the cooling sysmte (ie if you have an ally head / block).
I had a steel T-Piece in my original blade plumbing and that rusted a bit from the inside and quickly discoloured the coolant, Im not sure if it was
sufficient to do any significant damage over time or not, but I've swapped it for an ally part for peace of mind and since then, the coolant
stays very clean.
