How to paint the galvanized pipes?

Preparing the pipes and fittings

1. Clean the dust or dirt on the pipes with a rag, add some detergent or vinegar if necessary. A little bit gum turpentine can remove the sticker label residue, if any.
2. If you see any rust, sand it off with 120 grit sandpaper, and clean the residue.
3. What you need to do with the fittings is wipe them with a dry rag, with rough surfaces it won’t take you much effort to paint perfectly.
Once you've prepped the pipes, most of the work is done.
Priming and Painting
It is better to paint the assembled frame than separated parts unless the frame finished is too big, because it’s possible to scratch the paint when you assemble the pipes and fittings. So try to combine as more parts as possible before you start to the job.
Priming

Anti-rust primer is always a good choice when painting on galvanized metal. Simply spray or brush a single coat of primer on the metal, check the instructions on the can that how long it would take to dry. Only start to paint after the primer is dried.

Painting

It usually takes two coats to evenly cover the whole item, whether you apply the paint by brush or spray. Apply the first coat as soon as the primer has dried, and then sand lightly with 220-grit sandpaper and apply the second coat.
