Does wrought iron rust? Yes. Wrought iron is an iron alloy, so it rusts when bare metal is exposed to moisture and air. Aluminum does not rust because it contains no iron. That one difference shapes most of the choice between wrought iron and aluminum railings for a Connecticut porch, deck or set of front steps.
Both metals make a long-lasting, good-looking porch or deck railing. Here is how they compare on rust, upkeep, looks and cost.
Does Wrought Iron Rust, and Why?
Rust forms when iron reacts with oxygen and water. A wrought iron railing is protected by its finish, usually a powder coating. As long as that coating is intact, the metal underneath stays dry and sound.
The trouble starts with chips and scratches. Once bare iron is exposed, rain, snow and humid summer air go to work on it, and rust can creep under the surrounding finish. Road salt and ice melt used on steps in a Connecticut winter speed the process up.
How to keep a wrought iron railing from rusting
Inspect the railing every year for signs of deterioration in the powder coating. Look closely at welds, joints and the base of each post, where water tends to sit. Have any problem areas repaired or touched up right away so rust and corrosion do not get a foothold. Caught early, a small spot is a simple fix.
Wrought Iron Railings
Wrought iron is strong, heavy and durable, and it has a classic look that suits many older and traditional homes. It is often paired with wood to create a warm, rich appearance. The wrought iron produced today also contains steel, which makes it less expensive than the wrought iron of the past.
The trade-off is the yearly attention described above. If you like the look and do not mind an annual inspection, wrought iron will serve you well for a long time. You can read more about the benefits of wrought iron handrails and porch railings.
Aluminum Railings
Aluminum railings are made with small amounts of copper, magnesium and silicon for additional strength. Instead of rusting, aluminum forms a thin oxide layer that protects the metal underneath, and a powder coat finish adds color and more protection.
Aluminum is durable, weather-resistant and requires minimal maintenance. An occasional wash with mild soap and water is usually all it needs. It is available in many standard and custom designs, and it is generally the most economical choice for a porch railing.
Wrought Iron vs. Aluminum: How to Choose
Both wrought iron and aluminum railings come in a variety of attractive colors, and both are durable and impact-resistant. Aluminum is generally slightly less expensive than wrought iron and asks less of you over the years. Wrought iron offers weight and a traditional character that some homeowners prefer.
Think about how much upkeep you want to take on, the style of your house and how exposed the railing is to weather and salt.

If you are redoing the whole entrance, a new railing also pairs well with storm doors and door canopies and window awnings that keep rain and snow off the steps.
Frequently Asked Questions
Does wrought iron rust outdoors?
Yes, wherever the protective finish is damaged and bare metal is exposed to moisture and air. A sound powder coating prevents it.
Do aluminum railings rust?
No. Aluminum contains no iron, so it cannot rust. Its natural oxide layer and powder coat finish protect it from corrosion.
Which railing needs less maintenance?
Aluminum. Wrought iron should be inspected every year and touched up where the finish is chipped, while aluminum mostly just needs cleaning.
