Comparing Aluminum and Steel for Residential Railing Systems
Homeowners in need of railings face several choices, such as picking a style that suits the house, selecting a color that either matches or stands out from the exterior paint, and determining whether to use aluminum or 'iron' (which is actually steel) rails. Both aluminum and steel are widely used for railing construction, and each brings its own set of benefits and drawbacks.

Choose between iron or aluminum for a classic railing for your home.
When outfitting a home with railings, several choices come into play. You need to think about which style will complement the property best. You also have to pick a color that either harmonizes with or deliberately contrasts the house paint. Then there's the decision between aluminum and 'iron' railings—though what is commonly called iron is in fact steel. Both materials see frequent use in railing manufacturing, and each offers distinct pros and cons.
Benefits of Using Steel Railings
What people often refer to as "wrought iron" or "iron" railings today are actually made of steel. In the past, these railings were truly iron, but advances in processing led to the steel now used across all kinds of railings. Steel is highly malleable, so it can be shaped in numerous ways to replicate the look of antique railings found on older buildings. Steel railings provide strength, durability, and a long lifespan. The material can be bent, cast, and formed into an endless array of designs, giving homeowners a way to showcase their personal style and find the ideal design for their property. Steel accepts paint well and can be finished in virtually any color. Installing steel railings is straightforward, and they remain sturdy and secure for decades.
Drawbacks of Steel Railings
Regrettably, both iron railings and modern steel railings are susceptible to rust. This happens when moisture chemically interacts with the iron contained in steel. The reaction produces a different compound, iron oxide, which is significantly weaker than the original metal, according to ScienceBuddies. This can lead to cracks, holes, and crevices in the steel. Left unrepaired, rust can spread through the material and cause it to break. The chemical process speeds up under conditions such as acid rain. Although manufacturers apply various coatings to slow rusting, any damage to those coatings will allow rust to begin.
Benefits of Using Aluminum Railings
Aluminum, like steel, is malleable and can be shaped into many different railing designs to fit any purpose. It offers a clean, sleek appearance that improves the look of modern residential buildings. Unlike steel, aluminum does not rust, making it a suitable option for homes in damp environments. Aluminum railings can receive powder coating in a wide range of contemporary colors. Since aluminum weighs less than iron, it is simpler to install in hard-to-reach spots.
Drawbacks of Aluminum Railings
Aluminum lacks the strength of iron or steel, according to VikingFence&Deck. It will bend when subjected to significant pressure. Although aluminum railings do not rust the way iron does, they may develop a faint whitish film in spots where moisture gets through the coating.
