Iron or wood
| Iron | Wood | |
|---|---|---|
| Look | Slim profile, many decorative shapes | Classic turned or square profiles |
| Finish | Factory finishes such as satin black or bronze | Paint or stain |
| Changing later | Swap style by replacing balusters | Repaint or replace |
Common iron styles
- Plain square bar
- Single twist
- Double twist
- Single or double basket
- Single or double knuckle
- Hollow versus solid bars
Patterns
Many stairs alternate two styles, for example plain and twist, or place a decorative baluster every few positions. Pattern choice changes the parts list. Spacing requirements are a question for your contractor, not this guide.
Questions
Can I mix iron balusters with a stained wood rail?
Yes. This is a common combination.
