Which type of railing is better, aluminum or wrought iron?

Neither is better for every project. Aluminum is better for low maintenance and lower cost, while wrought iron is better for strength and a traditional, ornate look.

Aluminum does not rust, weighs less, and usually costs less to buy and install. It is softer than iron, though, and can dent. Wrought iron is very strong and suits detailed custom designs, but it can rust if the coating wears through, so it needs repainting or recoating over time. Many railings sold as “iron” today are actually mild steel, so ask what you are getting.

A quick way to choose:

• Pick aluminum for decks, patios, and balconies where you want little upkeep

• Pick iron or steel for heavy-duty use, custom scrollwork, or a classic look
