Zinc coating for mild steel 1

[Znjmech]

Hi all

I'm wondering if someone could tell me where could I find the specs for sn10/cu10/Fe zinc coating for mild steel, which is exposed to a humid ambient but not directly with the fluid. And what are the methods it could be done to withstand 100 hrs in saline water, and what could be an alternative less costly coating method for the same result?

I tried to use the American galvabizers association table in their website but noticed that I need to know a lot of details

Thank you very much for your answer. But the test specifications didn't help me resolve my first problem. As I indicated, I first need to know what is the current process that I named as: sn10 cu10 Fe. It's not mentioned in those standards. The name is just absurd.
And how can I find an alternative solution for that?

Thank you again

Dhoooo... sorry... I was thinking alternative-to your 10copper-10tin-?iron-zinc [very unusual] hot-dip coating alloy.

I am having a hard time understanding your answer, shall you please elaborate?

Why do you think it is unusual?
It's important to me to know that

 

[Znjmech]

Why did you put the ? mark before Fe? Should it also have a coefficient?

 

[Znjmech]

Is there anyone else with some information on this process?

You asked, "...and what could be an alternative less costly coating method for the same result?"

And then having been presented with the alternative, less costly method (hot dip galvanizing) that everyone knows about instead of the unknown one that you asked about, YOU then AGAIN asked "...And how can I find an alternative solution for that?"

That alternative, again, is the well known hot dip galvanizing process.

Now it's your turn, to explain to us why the well known hot dip galvanizing process is not acceptable.

Thank you for your answer, I didn't get him!! cause the answer wasn't clear for me. I didn't say it's not acceptable that time. hot dip might be the alternative.

In my first question I also have indicated that the treatment name is strange for me: sn10 /cu10 /Fe
My question is: if it is a zinc coating, why doesn't it have the Zn in its name?
