Cholla Powder coating

[dirtsurfer]

Even stainless-depending on the grade, can be rusty junk in a few years. Regarding rusting rebar, from my own experience and from closely watching construction in Mexico most rebar is rusty before it enters the walls. Somewhere on this site we discussed methods to relieve the rusty rebar problem and in some projects in the U.S. Teflon coated rebar is used. I have also seen fiberglass rebar which is pretty rare.

I use a concrete sealer on all my exterior concrete and that seems to help. I also finished my home

My cousin Jose says good contractors in Penasco will charge a bit more and paint all rebar with anti-rust paint before using it.

Funny, the "stainless" hardware that I used on my 52qt marine cooler for the jet ski was more expensive than the cooler itself and after 3 years now it's so rusted I would have to cut it out if I wanted to replace anything. Obviously it's made in China (Donald Trump china voice).

I talked to a guy in Santo Tomas that bought a stainless barbecue and got two seasons out of it before it fell apart.

The difference in Stainless Steels are amount of nickle added in the mix. The more nickle the less a magnet will stick to it and the better rust Resistance. I normally use 316 stainless.

Powder coating does not work well on vehicles either. It looks great just after going on but the vibration of driving causes small cracks and then yes rust grows. The next issue is what is required to repair rust under powder coating? Had a large security/screen door done here.. Lots of little welds. In a few months, rust.
I have seen different examples of 'stainless steel' parts attached next to each other at the same time with one piece still shiny and the other rust.
I want to put good stainless hinges on the screens beachside. The aluminum ones available here last maybe a year even after I paint them front and back before installing. what grade would you suggest? assuming I can find them.

Galvanized might last longer

Galvanized might last longer

That will help cover up the pin holes that start the rust bleed.

Normally the only way to make powdercoat last is to hot dip galvanizing before powdercoating.

One thing about galvanizing is if you are using tubing you have to have weep holes for the galvanize to enter and exit the tubing. At least 3/8” holes. We used to use a 45 caliber bullet to plug the hole then file to smooth.

Can't you just buy already galvanized steel tube? I've heard you can get pretty sick off of the smoke if you mig weld galvanized steel.

MJ your are correct. Ventilation is key when welding galvanized

you can buy stock pieces of tubing and then have it galvanized. After cutting it and welding it together you can use a galvanizing spray. It’s not the same as having the welded product galvanized. Drink a quart of milk before you weld galvanize and yes ventilation is key

Like trying to get your air conditioner panels powder coated, I did have a reem air conditioner last 15 years, unbelievable the other a York had the bottom rot off everything fell through and it kept working lol, so should I get the new ones powder coating, they did paint the new ones haha.

I have a Mirage mini-split that sits on my roof still doing pretty well avoiding rust since 2012.
Trick is, I keep it covered when we're gone with a vinyl/leather look cover made in Penasco.
I'm also pretty close to the water and the cover is off at least 50 days per year.
I would like to know how it was painted to stay that good for over 8 years.
I'm glad that Mexico sells mini-splits that cost less than $500 and last awhile.

Once they get from Mexico to Canada there cost just to buy a bare bones unit is $1500 to $2000. Installation extra

Pretty amazing they are so much in Canada. I see people selling Mirage units in Phx for $50-100 more then Penasco does.
All 3 of my units were installed for an average of $50 each. In Phx they want $500+ to install.
