How Durable Is a Wrought Iron Railing?

Indoors, an iron stair railing will last for decades. Today’s iron balusters are low-carbon steel with a powder coat or faux finish, so they bend instead of breaking and don’t need painting. They’re made for indoor stairs only. Our iron balusters aren’t galvanized, so they can rust outside. For porches, decks and exterior steps, use stainless steel like our AXIA railing.

How Long Do Iron Railings Last?

Indoors, as long as the house. The steel doesn’t wear out, and the finish only needs attention if it gets scratched or chipped. The thing most likely to need work over the years is the installation, like a baluster that wasn’t set in epoxy working loose. See how to fix loose metal balusters.

Does Wrought Iron Bend or Break?

Steel balusters bend before they break. That’s one reason steel replaced old cast iron, which is hard but brittle and can crack. A hard hit can bend a hollow baluster, while solid balusters are stiffer. See solid vs. hollow balusters and steel vs. wrought iron vs. cast iron.

Will Iron Balusters Rust?

Not indoors under normal conditions. The powder coat or faux finish seals the steel. Rust can start where the finish is scratched or chipped and the bare steel gets wet, so:

• Touch up scratches with a touch-up pen or touch-up spray can.
• Don’t clean with soaking-wet rags, and dry around the base shoes.
• See how to clean and care for iron railings.

Can You Use Iron Balusters Outside?

No. Our iron balusters are made for indoor stairs and aren’t galvanized, so rain and humidity will rust them over time. For outdoor railings, use stainless steel. See the best railing for outdoors.
