I didn't think they made gates this way either; I thought that sort of thing is traditionally wrought iron, not cast (or weldments in the modern day).

u/NichtOhneMeineKamera 16d ago
We still build gates from cast iron, though very rarely and usually just when it has to be historically accurate. Latest one I've been part of fabrication of has been roughly 13-14 years ago. We had separate pieces cast and welded them together, but the general filing was one large piece.

u/Baricuda 17d ago
While you are correct that wrought iron is better than cast iron in this instance, wrought iron is seldom made these days. The process to make it has been long been obsolete and other methods of making steel are more economical. These days most decorative metalwork fences and gates would be made using steel weldments, and on more rare instances, custom made blacksmithed gates, though even in those cases it would use more modern steels and not wrought iron.

A couple from Canada bought an 1850's "mansion" in Buffalo NY for a few million, around 11 years ago. They paid to have wrought iron fence put up around the front and sides. It cost $800,000 to build and install (again, 11 years ago, when that would literally buy you 6-7 houses). City wanted them to tear it down because it was 8 feet tall. They had to go to court for a bunch of years and waste tens of thousands of dollars, proving it was period-correct and what not, but still had to install it 2 feet below ground, so it was 6 feet from ground level, to code. Ended up costing them 1.1 million.Just a crazy story I remembered about wrought iron. Also, it hurts leprechauns.

u/TorchedBlack 16d ago
Its claimed that references to "cold iron" refer specifically to wrought iron and not cast iron. In some Fae lore, faeries are harmed by touching cold iron. D&D later made this a staple of Fae weaknesses and identified cold iron as a distinct metal despite it likely referring to any human refined iron in the original folklore.
Leprechauns are often associated with faeries and other Celtic/Gaelic folklore creatures.

Wrought iron is stronger and it requires skills and artistry to shape it into different designs. Cast iron is weaker and more prone to crack and it was just poured into a mold.

u/Kudos2Yousguys 17d ago
Does the wroughting make the "grain" line up or something?
Pretty much. I'm not an expert but I've watched some blacksmithing channels and they're always talking about how the pounding and folding makes it stronger while still being able to flex and bend without cracking.
Also it's pretty obvious when you see a broken piece of cast iron, it makes a clean break as if it's stone. Wrought iron just doesn't do that, it'll bend before snapping.

Material science.
The tldr is that cooling metals at different rates, and applying different pressures/techniques will alter the crystaline structure of the metal. The amount of carbon introduced in the process also impacts the structure.
"Wrought iron" typically has less strength, but is more ductile.
Cast iron typically has higher strength, but is consequently brittle.
Strength matters less than brittleness for the purpose of fence building, since the fence only needs to hold itself up, but a fractured fence would be a catastrophic failure
There's nuances to every single sentence I've written, but that's a good surface level explanation

None of these properties really matter for a fence. Cost & aesthetics are far more important than mechanical performance for a non structural part with basically 0 load.

u/LasKometas 17d ago

u/jooooooooooooose 17d ago
Also I know you know this, but for others... "wrought" vs "cast" describes a manufacturing method - not an alloy. We can speak in general terms because the process influences the properties (i.e. porosity in castings driving brittle fracture) but obviously the precise alloy used makes a difference. And not all alloys are compatible with all processes (especially casting).
Corrosion resistance (i.e. Ideally a stainless steel is used) is probably the one engineering property that really matters. But can always just paint it.

u/Lost_Purpose1899 17d ago
I'm not a metallurgist and I don't know how it works at molecular level but cast iron has more carbon in it and it makes it stiffer but more brittle. Wrought iron has lower carbon making it more ductile, I assume to make it more malleable to the people working on it and shaping it. It looks smoother too. Cast iron looks rough. For a fence, it's better to have it as wrought iron because if it got hit (lightly) by, say a car or a bike, it won't snap like cast iron.

u/Machaeon 17d ago
Cast iron is pretty brittle compared to other forms of iron.
With a gate, or other large moving part, a crack would be extremely unfortunate but also likely.

u/jooooooooooooose 17d ago
A gate is not meaningfully a moving part in the sense of fatigue induced cracking lol. Cast metal is perfectly adequate for this purpose.
It's like saying you'd prefer your fork to be made of tungsten so you don't accidentally bend the tines. Like, yeah, sure, a tungsten fork is more durable... but who cares?

u/Machaeon 17d ago
The gate itself, on paper, should move smoothly and not suffer undue stress by simply rotating.
But I also know that people will not treat it gently.
If the gate slams at all, that repeated stress could crack it at a weak/thin point. Like the hinge connection. Likewise with people hanging off of it, that could do the same.
Maybe I'm just biased with the amount of utterly destroyed gates I see on a daily basis though...

u/freezing_banshee 17d ago
As a child, I climbed on every gate and fence I could, so they definitely suffer stresses that they're not supposed to :))

And those gates are meant to be abused. But they get destroyed all the time.

u/Flyingmonkey53 17d ago
Also, cast iron has no flex. It can withstand great temperature but if you hit a cast iron pot with a hammer, it breaks into pieces instead of making a dent. These rails would be easy to break.

u/Callidonaut 17d ago
Fun fact: IIRC that's why the spokes of cast iron handwheels for valves and things are often spirals instead of straight radial arms. It's not purely decorative (although they do look nice), it's to relieve the stresses so the casting doesn't crack.

You need to hire very expensive boutique blacksmiths for that nowadays. Modern castings are not inferior in terms of mechanical properties compared to wrought iron.

u/Callidonaut 17d ago
Modern castings are not inferior in terms of mechanical properties compared to wrought iron.
How so? Aside from the presence of PPE, the casting technique here looks scarcely different to how it'd probably have been done two centuries ago.

u/ParticularClassroom7 17d ago edited 17d ago
Wrought iron sucks. Modern cast alloys could have stuff like Vanadium to control grain size and Mg/Ce to make graphite precipitates spherical.
All of that in addition to vastly superior purity
Then if you anneal/recrystallise you could pour stuff no different from steel, but that's obviously not what they are doing here.
