I'm making a 9 metre long fence from 25mm diameter galvanised water pipe and want to fix 2 metre high corrugated iron sheets with aluminium rivets. Is there any problem using the dissimilar aluminium rivets into iron?

Wouldnt think so. No rust.

Don't use aluminium. You risk having your rivets corrode. Best to use ferrous with ferrous whenever possible.

Yep, when wet the ally will react with the galvanising on the iron, and will corrode the aluminium. Then the iron sheets will fall off, or blow off and injure somebody. My choice would be monel metal or stainless steel, but they are hard rivets to set unless you have a lazy tongs riveter.

Are your corrugated sheets galv or zincalume?
12 x20 tek screws would be stronger than rivets

He is using pipe for nthe framework. Do tek screws screw into pipe?

Pilot hole, then the metal drilling tek screws.

Using steelteks you don't need the pilot hole.

I would use steel teks as well. If the pipe is thick, use superdrive screws

What are superdrive screws? and if I use them or steel tek screws can I use a normal drill to install them or do you need a special drill to install tek screws?

A decent powered battery drill will do it. Avoid a cheapie. Superdrive are tek screws that will go through thicker materials. Get them from Steel and tube roofing. You will need a 3/8ths hex head on your drill

The reason I suggested a pilot hole is to avoid the tek screw wandering whilst it gets seated, especially on a smallish diameter tube.

You don't need pilot holes with zip screws, they bite and go straight in.

Will a tek screw go through the water pipe which I think is 3 to 4 mm thick?

yep, but to be sure use the superdrive version. It's a bit more expensive but works as well as a drill bit.
