Key takeaways
- Wood is classic and flexible, but needs care.
- Aluminum is low-maintenance and strong.
- Cable and glass keep the view open.
- All railings must meet local height and spacing rules.
Wood railings
Wood railings are the traditional choice. They can be built in many styles, painted or stained to match the house and repaired easily. They need sealing and occasional replacement of posts or balusters.
Posts should be anchored to the frame, not just bolted to the deck boards.
Aluminum railings
Powder-coated aluminum does not rot or rust and keeps its color well. Slim balusters give a clean look, and sections install quickly. It is a strong choice for owners who want low upkeep.
Cable and glass
Stainless cable is thin, so views stay open, and glass panels block wind and give the clearest sightline. Both suit modern homes and homes with a view. Cable needs correct tensioning and strong end posts. Glass needs cleaning.
Check the rules
Local codes set minimum guard heights and limit the gap between balusters. Cable and glass need special attention to spacing and engineering. Your builder should follow the rules for your area.
