Once the framing and decking are decided, railing is the next big choice on a Danville, KY deck project — and it’s the one most homeowners haven’t researched, because five materials can all look reasonable in a showroom photo but perform very differently outdoors.
What are the main deck railing options?
Pressure-treated wood, aluminum, composite, cable, and black metal baluster systems are the five options we install most, and each trades off cost, maintenance, and view differently.
- Pressure-treated wood — the cheapest option and matches a PT deck, but needs the same staining/sealing schedule as the decking itself
- Composite railing — matches composite decking and needs no finishing, at a higher upfront cost than wood
- Aluminum — thin, strong balusters that open up the view more than wood, low maintenance, holds paint well long-term
- Cable rail — the most open view of any option, but it needs a stiffer post and frame to keep the cables from sagging over a wide span, which adds engineering and cost
- Black metal balusters with a wood or composite top rail — the most common look on newer Kentucky decks, mixing a low-maintenance baluster with a warmer top rail material
Which railing material costs the most?
Cable rail and aluminum typically sit at the top of the range because of the hardware and post engineering involved; pressure-treated wood sits at the bottom. Across a typical Danville deck, railing adds roughly $30-$75 per linear foot installed depending on material, labeled as typical, on top of the framing and decking cost covered on our deck cost page.
Which one should I actually pick?
If the deck looks out over a yard, tree line, or view worth showing off, cable or aluminum earns its higher cost. If the deck is close to a neighbor’s fence line or the view isn’t the point, a wood or composite baluster system does the same job for less. Composite and aluminum both make sense if you’re already tired of the maintenance schedule on a wood deck elsewhere in the project — see our note on how often a wood deck needs resealing before you decide.
Common questions
Can I mix railing materials with a different decking material?
Yes — a composite deck with aluminum or black metal railing is common and often looks cleaner than matching composite railing to composite decking.
Does cable rail really need a stiffer frame?
Yes. Cable under tension pulls posts inward, so cable systems need larger or reinforced posts and closer post spacing than a baluster system to stay code-compliant and avoid visible sag over time.
Do all these options meet Kentucky guard height code?
The material doesn’t determine code compliance — height and baluster spacing do, and that applies the same regardless of material. See our railing height code guide for the specifics.
