Alright, let’s talk about this electro galvanized and hot-dipped galvanized stuff. I ain’t no fancy engineer, but I’ll tell ya what I know, the way I understand it.
So, you got these two ways to make steel last longer, ya know, keep it from rusting all to pieces. They call it galvanizing. Sounds fancy, but it ain’t. It’s just puttin’ a coat of somethin’ on the steel, like paintin’ a fence, but better.
First, we got this hot-dipped galvanized thing. Imagine you got a big ol’ pot of melted zinc, like when you’re meltin’ wax for candles, only hotter. They take the steel, whatever it is, a pipe, a sheet, whatever, and dunk it right in that hot zinc. It’s like dippin’ a donut in glaze, only this ain’t sweet, it’s tough.
This hot-dipped way, it makes a thick coat, real thick. It’s kinda dull lookin’, not shiny or nothin’, but it’s tough as nails. Good for big stuff, stuff that’s gonna be out in the weather, rain or shine. You know, like fences, or those big metal sheds they put up on farms now.
- Hot-dipped is thick and tough.
- Good for big stuff and outdoor use.
- Looks kinda dull, not shiny.
Then there’s this other way, this electro galvanized. This one’s a bit different. They don’t dip it in hot stuff. Instead, they got this liquid stuff, like water but with chemicals in it, and they put the steel in there. Then they got this other piece of metal, zinc, and they run electricity through it. It’s like magic, but it ain’t. The electricity makes the zinc stick to the steel, real thin-like.
This electro galvanized coat, it ain’t as thick as the hot-dipped kind. It’s smooth and shiny, looks nicer, ya know? But it ain’t as tough. It’s good for small things, things that don’t need to be super strong, like little screws and bolts, or maybe those fancy metal things they put on furniture.
They say electro galvanized is made by puttin’ zinc on cold rolled steel. That cold rolled stuff, it’s already kinda strong, and the zinc just helps it last longer. And because it’s done at a low temperature, it don’t mess with the steel, keeps it strong the way it’s supposed to be. This zinc coat, it’s even all over, not thick in some places and thin in others, which is good, I reckon.
So, which one’s better? Well, it depends on what you need it for. If you got somethin’ big and tough that’s gonna be out in the weather, go for the hot-dipped. If you got somethin’ small and pretty, the electro galvanized will do just fine. It’s like pickin’ between work boots and dress shoes, ya know? Both got their place.
I saw somethin’ once, a chart or somethin’, showin’ the difference. It said hot dipped is thicker and lasts longer, but electro galvanized looks better and is good for small parts. It all makes sense when you think about it. Thick and tough for the big jobs, thin and pretty for the little ones.
You can buy all sorts of galvanized stuff, you know. Bushings, unions, pipes, elbows, all sorts of things. They even got plates, thick ones too. Price is different dependin’ on what you get and how big it is. But one thing’s for sure, galvanized steel lasts longer than plain steel, that’s the whole point.
And that’s about all I know about it. Hot-dipped for tough stuff, electro galvanized for pretty stuff. Thick coat, thin coat. Dull finish, shiny finish. It ain’t rocket science, just common sense, if you ask me.
Remember, this is just how I see it, plain and simple. Someone else might tell you different, use fancy words and all. But this is how I understand it, and it works for me.
