What Kind of Metal Handrail Should I Use for a Spiral Staircase?

Steel

• Steel is the most common handrail metal because it's inexpensive and can easily be shaped to fit the curve of your staircase. Steel handrails are usually finished, either painted or powder coated, but an unfinished steel can add a raw industrial look to an urban-chic loft. Tubular steel handrails work well with Art Deco looks, and ultra-modern designs incorporate thin steel cables into the support system for a lighter-than-air look. Steel is also a good choice for outside, because it is quite weather resistant when properly finished. Most prefabricated spiral staircase handrails are made of steel.

Iron

• Iron is more expensive than steel, but cast iron is more affordable than wrought iron. Iron handrails are heavy, so they may not work well on a rickety wooden staircase. They frequently include decorative scrollwork and intricate designs, and can be as simple or ornate as you'd like. Designs can be light and airy like the famous French Quarter railings, or heavy and baroque like the gates at an old cemetery. Iron handrails are generally left unfinished except for a protective oil rub, but can be painted if the natural black is too dark for your taste.

Copper/Bronze/Brass

• Copper, bronze and brass are probably your most expensive options, but they can be incredibly beautiful. These metals develop a gorgeous patina when exposed to the elements, or you can keep the original color with regular cleaning and polishing. All three work well in antique decor styles, but make sure the handrail is the same metal used for the hardware in the rest of the room. Copper and brass are very bright and provide an instant focal point, but bronze can be more subdued, allowing a more ornate design without becoming tacky.

Mixed Metals

• If you simply cannot decide on a metal, consider a mixed metal handrail. It may be as simple as a steel structure with brass accents, or you could go the full-inlay route if your budget allows. Don't use more than three metals at a time, and use the decorator's proportion rule: 70 percent of the railing should be one metal, 25 percent should be a secondary metal and the remaining 5 percent should be an accent metal. A ratio of greater equality would likely result in a jumbled, gaudy design.
