Aesthetically, wrought iron always looks good. It just does. But a few people might claim that it rusts easily, which is not true if the product is finished and maintained properly by a manufacturer. Other than those considerations, wrought iron products are virtually impervious to rain, snow, or heat without a finish, and so does wrought iron rust?
Yes, wrought iron can rust if exposed to moisture or air. In oxygen and water, wrought iron will rust due to oxidation. Wrought iron rusts if it is continuously exposed to humidity and precipitation.
With air and moisture coming in contact with the iron, it is only a matter of time before corrosion sets in.
Also, as one of the most popular building materials on the market, wrought iron is both strong and attractive. Most consumers are familiar with the ornamental iron used for outdoor gates, fences, and decorative elements, but not everyone knows if it will corrode or rust.
This article provides a helpful overview of wrought iron to help you decide if it’s the right material for your next project.
About Wrought Iron
The notion people have about wrought iron is not always correct. When some people hear of wrought iron, what comes to mind is early iron works, while some think that early ironworks measure human creativity. A knowledge of this kind of metal will set these notions straight.
Compared to pure iron, wrought iron has a higher carbon content.
There are interesting differences between wrought-iron and cast
iron. One difference between wrought iron and cast iron is that while cast iron is melted and poured into a mold, wrought iron is heated and worked. If you want to make an item from wrought iron, you will heat it and use tools to work it into whatever shape or design that you want.
To create an item with cast iron, the iron will be melted and poured into a mold having the shape of the item. But to create an item from wrought iron, you will heat the iron and, while it is still hot, you will work it into the shape of the item using a hammer or other tools.
How To Protect Wrought Iron Items Against Rust
The high level of carbon present in wrought-iron makes it less susceptible to rust than pure iron. However, it can rust. But there is a lot you can do to protect your wrought iron item from rust. Here are some suggestions:
Galvanizing your wrought iron item is one way to protect it from rust. Galvanization is a process that guarantees your metal item is safe from direct contact with elements like moisture and air that can cause corrosion. Through galvanization, zinc is applied to wrought iron to protect it from direct contact with water, moisture, and other elements that can cause rust and other elements that can harm the wrought iron. The wrought iron will not rust if the galvanization is well done and the zinc layer does not go off.
Surface plating is another way to protect your wrought iron item from rust. Treating your wrought iron surface with chrome or nickel is a sure way to protect it from the elements and corrosion. The lack of iron in nickel and chrome makes them act in protecting wrought iron from corrosion.
Painting your wrought iron is another way to protect its surface from direct contact with the environment and elements such as humidity and air. When painting your wrought iron, ensure to choose a paint that is made from metals. If possible, see professional advice to help you make the right choice. When painting your wrought iron, apply the paint generously but not too thick. If the layer of paint on the wrought iron is too thin, it may not protect the iron from direct contact with oxidation agents. Ensure that the paint dries according to the manufacturer’s recommended time. The thing with painting is that it does not protect the wrought-iron surface for as long as other treatments do.
If your wrought iron metal is outdoors and it is susceptible to some elements, powder coating is a smart choice. Powder coating prevents your furnishings from corrosion-causing elements. One good thing with powder coatings is that it is reputable for longevity. It will not fade or crack for a long time. If you do not want to think of your wrought-iron items needing your attention so often, powder coating is one of the best options you can go for.
The way you store your wrought iron item will determine how much exposure it will have to corrosion-causing elements. For instance, keeping your equipment and tools made of wrought iron outdoors exposes them to elements such as humidity, air, and moisture. Keeping your items in a shaded area is preferable to keeping it in the open. Shielding them from continuous and direct contact with the element will make them more susceptible to corrosion. Also, storing your items in a place with improper drainage can also expose them to water. If you have heavily built items made of wrought iron, keeping them in a solid floor or a place with proper drainage is preferable. This will prevent standing water from the area and make them less susceptible to contact with water and oxygen.
Very importantly, if items are not in use, it is better to keep them indoors in a safe and dry place. Items you rarely use should also be stored indoors in a place with controlled humidity. While storing these items, covering them up with plastic covers, for instance, is advised.
Proper maintenance of your wrought iron items will also prevent them from rusting. Clean them regularly. If you notice any rusted spot, take care of it before it spreads to other areas.
Like every other metal, wrought iron will rust if it is exposed to moisture and air. But there is a lot you can do to prevent your wrought iron from rusting, like galvanizing in painting it, for instance. Storing your items properly is essential for keeping them from corrosion-causing elements.
