Compression tank: galvanized or painted?

Replacing a old Thrush compression (no bladder) tank. I believe it's plain steel. Any issues with going with a galvanized tank? Or should I just go like for like.

Thanks!

    Galvanizes will not hurt anything. Steal is also fine. Whatever you can get easily and economically.

    After you make that expensive repair and you still have the same problem, What will you check next?

    don’t screw copper directly to galvanized metal. No glycol allowed in galvanized metal.

    Does the tank have air tube fitting into it? B&G Airtrol as an example? An air purge fitting on the boiler?

    Why not a diaphragm tank at a fraction the size and cost?

    All iron pipe. Has an Airtrol,so I'm good.

    I'm going with plain steel , in another 60 years I won't be in a position to care.

    Hat's off to Quality Tanks! Got my tank in ONE DAY after the local distributor said 3-5 days and "we don't sell a lot of those, just get it from the manufacturer". Sweet little 8 gal. tank.
