Default Cleaning and painting galvanised steel

Hi

To cut along story short I need to build a structure in my garden which
is built out of scaffolding. I have bought some poles and connectors.
They were second hand so need to be cleaned and painted.

A cuple of questions

With regards to cleaning I am planning on sanding them down and then
using sugar soap to wipe them down. I have had good results with sugar
soap for cleaning some iron weights. Will suagr soap help or is there
something better? Its just to get the dust and stuff off really.

http://www.screwfix.com/p/no-nonsens...der-430g/21982

The connectors are pretty filthy, some of them are just covered in dirt.
I will probably leave them in a solution of sugar soap and then wire
brush them. Any other ideas?

Secondly I need to paint the scaolld poles.

I have used Hammerite for another job recently and whilst it does the
job the stuff is far too expensive for the quantities I will need,

Therefore I plan on using anjormal metal primer and probably using gloss
or silk paint.

The structure will be left outside in all weather but not abuse so I
need paint that can stand weather but not necessarily 'use'. I
understand as long as I prime is properly the paint should just go
straight on.

Anyone know the cheapest way to paint galvanised steel? Hammerite or
using a seperate paint primer method?

If I can get them shiny and clean and silver I may not even need to
paint but that looks unlikely.

I would hire a grit blaster. They are ideal for complex shapes and a lot
faster than sanding. You won't need to soak first either.

Excellent bits of kit, very, very effective.

I can't remember what we actually used, but when we painted the then new
hot dip galvanised fittings on the boat, we used a suitable,
for-galvanised primer followed by the same marine gloss paint that we
used on the rest of the boat ( I put my hand up at an auction and got
many cans of unknown colour paint - turned out to be all the same decent
colour for, I think, a fiver).
That was 25 years ago. We have only repainted where chains have run over
it. It is now a bit matt.
