Which is cheaper, glass or metal railing?

While glass railings do come with a higher upfront cost compared to iron railings — especially straightforward, no-frills designs — they tend to be the smarter long-term investment. Iron railings, particularly in humid climates or coastal areas, demand ongoing maintenance like repainting and rust prevention treatments, which adds up over time. Glass railings, on the other hand, are much easier to maintain down the road — they won't rust, and they hold up significantly better against corrosion, making them a more hassle-free choice in the long run.
