Rusted Metal Stair Restoration

Hello DIY forums. I need to know the best inexpensive way to restore the metal stairs that lead to my backyard. The paint and metal are chipping pretty badly and I think it would be a bad idea to just paint over it. How should I prep it? (Sand?, scrape?) Should I use a primer after prepping? What kind of primer should I use? What kind paint should I use after that?
Sorry for my ignorance and all the questions. I just want to do this the right way so it won't happen again. Thanks.

Can you include a few pics? Take one from a distance and another close up.

The experts will be along shortly, but yes I think a good scrapping (sandblasting would be in order. Then a good high end primer. Followed by your color of your choice. Is this domestic to US or are you non-US?

Ideally sandblasting or otherwise getting back to shiny metal is best ..... but maybe too expensive
I'd use a wire cup on a grinder and clean the best I could then apply a coat of a rust inhibitive oil base primer followed by 1-2 coats of oil base finish paint. If for some reason you need/want to use latex for the top coat - apply 2 coats of primer!

Thank for the advice!

How about this for the primer?
Rust-Oleum Stops Rust 1-qt. Flat Rusty Metal Primer-7769502 - The Home Depot

A finish paint similar to this?
Glidden 1-qt. Just Teal Interior/Exterior Oil Paint-GL 310 04 - The Home Depot

Any significant advantages latex has over oil based?

Should do fine ...... but you'll need more than a quart of each

The only advantage that latex has [other than quick dry and easy clean up] is it's less likely to fade in the sunlight. Given a choice, I'd use oil base.

If it was me, I would first treat the rust after scraping with Ospho Ospho Rust Treatment - Since 1947 Ospho changes the chemical makeup of the rust and preps it to receive the top coating. Ospho used to be sold by Duron, which was bought out by Sherwin Williams - so that is where to begin your search. I think that if you do not treat the rust now, it will just bleed back through in time.

I would then use a direct to metal coating such as Devflex https://www.norkan.com/pdfmanuals/De...ex-4206-qd.pdf It dries exceptionally hard and I use it to paint metal stair railings at a local hotel as well as the exterior room doors that get lots of sun exposure. Previous oil based paints faded and got hazy, I painted the doors with Devflex 4 years ago and they still look great. Devflex is purchased at a PPG/Glidden Professional store - Formerly call Dulux Paints.
