plastic never rusts leaks etc plus must be cheaper

I know some people are under the impression that plastic lasts
forever... but it gets brittle and eventually cracks. I was removing
a sink today to install granite counter tops and the brittle plastic
piece which connects to the stainless steel broke off on me instead of
unscrewing. I stored a lot of old mail rubber-banded by date and when
I went to go through it years later to throw 99% of it out all the
rubber-bands had broken by themselves. The rubber hoses in your car
eventually leak. Ultraviolet also causes many plastics to fall
apart. Many plastics are even slowly eaten by microbes. While
plastic is a miracle of "modern science" and the best choice for many
many applications it is normally not a good idea to count on it
lasting longer than concrete, stone, or metal which was properly
designed and maintained. I do not know if it is the right choice for
the OP's application, perhaps it is. It is probably the cheapest.

These things are an australian icon and take on a second life when
rusted out as wood sheds, cubby houses, dog houses, chicken sheds etc
etc.

My existing tanks have a polymer film applied to the inside called
'Aquaplate' which protects the metal from the effects of electrolysis.
The manufacturers of this steel "BHP" gaurantee itl for 25years.

You can buy this stuff in sheets so I am really thinking hard about
having a crack at it.

Also, does anyone know if solid rivets are much stronger than 'Pop'
rivets.?


I cant see how you can roll corrugated iron without a set of "corrugated
iron rollers". You can make tanks out of flat sheet but you said you wanted
it to match what you have already. Also moving and supporting a tank made
out of flat sheet is more work.

Solid rivets are stronger in sheer and tension than "normal" pop rivets.

If i was making a DIY water tank i think i would use a plastic lined hole
and put some sort of decking over the top.
