CLIMATES NOT TO USE COR-TEN®:
COR-TEN® steel requires alternating wet and dry cycles to form a properly adhered protective layer. Areas that have salt laden air, high rainfall, humidity, or persistent fog are typically not the proper environment for COR-TEN®.
The new bridge is made of marine-grade aluminum.

Galvanization was popular for a brief time while the industry was still trying to find replacements for lead in paint that didn't have crap performance.
Cold galvanization is expensive and involves nasty chemicals. Hot galvanization is cheaper but not as cheap as paint and involves equally nasty chemicals and molten metals.
Basically paint is cheap and good enough.

The number of times I have to manually edit a wikipedia URL every day to remove the ".m" part is getting frustrating. I'm sure there's a browser extension for that but really, I blame wikipedia's poor ergonomics.

It actually does, but only when deciding to show the terrible mobile site instead of the desktop one. Even on a bloody iPad.
really seems much ado about nothing.
Either you increase the number of 'machines' (lines in this case) or you increase your drying area foot print to compensate.
Once you do the latter you can produce at the same rate assuming all products produced are identical) since you the ones coming out the dry end do so at the same speed as the input end.
Edit: This does assume production demand is constant, longer pipelines make responding to demand more difficult.
* Water based paintings dry much faster than oil based paintings
* The durability is pretty much the same
* The scratch resistance of oil based paintings, once fully dried, is light years better than that of water based paintings.
In some aspects the green movement has brought us water based colors where you could water your home plants with but are inadequate for some (read: wide) range of application.
You're right. There isn't. It's taken for granted that you are aware of the fate of unpainted steel in a salt air environment.
Those things are not painted and google told me that you can calculate how much is oxidized in a year.
I would really love to know how a shipping container is so much more fragile.
Perhaps it is not that relevant but in masses it makes a relevant amount of money. Like steel container 20 years and with color 25 years and that makes it just better.
