Cast Iron shelf brackets versus Wrought Iron brackets; the difference
So what is the difference between wrought iron and cast iron shelf brackets? Good question. Most people know there are two types but don’t know the difference. While both can be used in a decorative way in your home they are actually different. The difference is the structure of the metal. Cast iron is more brittle, so if you drop it or knock it with something else the risk it will break is huge. Wrought iron is strong and can be used for more heavy jobs. The reason is the way in which they are made. In the first case the metal is melted with a high temperature so it becomes liquid. It is then poured into a mold, becomes solid again and voilà there is your bracket. In the second case the metal is slowly heated and then gets worked by a blacksmith (or nowadays often in a machine hall). So that explains why wrought metal is often called “worked metal”.
Wrought metal brackets tend to be better suited to withstand the weather without showing effect of rust or corrosion. You should use antique cast iron brackets inside your home, not outside. Modern cast iron brackets are not pure iron, they are mixed with some other metals. This gives them more strength and you should be able to use them outside to.
Today, both wrought iron and cast iron shelf brackets are hugely popular for both decorative and practical purposes. (although if practical purpose is your main reason I would still choose the wrought version). Let me sum up some of the possibilities:
Antique cast iron shelve brackets – Are often more sturdy build then the Victorians.
Victorian cast iron shelve brackets – these have a few types like the Gothic, the symbolic decorated Victorian and the vine brackets.
Romanesque cast iron brackets – Have a simple clean design, for the more modern styles.
Dutch cast iron brackets – My favorite. I’m originally from Holland so I like tulips and delfts blue, they make me think back to my childhood.
Most are coated black or white, not only for the looks but also to prevent corrosion. Today you can use them to support heavy items, But you should use longer screws. Well I hope this article explained you something so you can make an informed choice about which material to use.
