Deck Railing Materials Comparison: 6 Options for BC Decks in 2026
Deck railing materials comparison, straight up: aluminum wins on cost and zero maintenance, glass wins on the view, and wood, composite, cable and vinyl all cost less up front but ask more of you later. We only build aluminum and glass. Here’s the honest case for all six.
Every aluminum and glass railing we build is designed, made and installed in-house by our own West Kelowna crew.
Deck Railing Materials Comparison: 6 Options for Every Okanagan Deck
Six materials show up on Okanagan decks: aluminum, glass, wood, composite, cable and vinyl. Pick the wrong one and you’re out staining every spring, or replacing posts in ten years instead of thirty. We build aluminum and glass ourselves, in-house, with our own crew. The other four have real uses too, so here’s the straight comparison before you decide.
| Factor | Aluminum | Glass | Wood | Composite | Cable | Vinyl |
|---|---|---|---|---|---|---|
| Maintenance | Annual rinse | Wash for clarity | Stain yearly | Occasional wash | Periodic tensioning | Occasional wash |
| View | Partial (pickets) | Unobstructed | Partial | Partial | Near-clear | Partial |
| Typical lifespan | Long | Long | Shortest | Long | Long | Moderate |
| We build it | Yes | Yes | No | No | No | No |
| BC code compliant | Yes | Yes (12 mm tempered) | Yes | Yes | Yes, with spacing | Yes |
Aluminum Deck Railing: The One We Build Most
Aluminum deck railing is what we install more than anything else, and there’s a reason for that. Heavy-gauge aluminum pickets, powder-coated, with custom color matching, and it doesn’t need much from you. An annual wash with soapy water is the whole maintenance routine.
Metal Deck Railing That Doesn’t Rust
Aluminum develops a thin oxide layer that protects it from the inside out, so it doesn’t rust the way bare steel does. It handles Okanagan freeze-thaw cycles and 35C summer afternoons without expanding or cracking. The one honest downside: pickets block part of your view, so if you paid for a lakefront lot, aluminum alone won’t show it off the way glass does.
Deck Glass Railing: Built for the View
Deck glass railing is the other half of what we build, and it’s the only material that actually disappears. We use 12 mm tempered safety glass in frameless or semi-frameless aluminum frames, so the lake or the valley stays the focal point instead of a row of pickets.
Frameless means the glass sits in a base shoe with no top rail, so there’s nothing at all between you and the view. Semi-frameless keeps a slim top rail for extra rigidity on longer runs. Both use the same 12 mm tempered glass and both meet BC code. See more glass styles on our glass deck railing page.
Glass asks a bit more of you than aluminum. Fingerprints and water spots show up faster, especially with spring pollen, so plan on wiping it down more often than you would an aluminum picket. On a backyard that looks at a fence, that extra cleaning isn’t worth it. On a deck that looks at Okanagan Lake, it is.
Attaching Deck Railing to Meet BC Code: Wood, Composite, Cable and Vinyl
Whatever material you land on, attaching deck railing in BC means meeting the same code every time. Guards need to be 900 mm high (about 35.5 inches, usually just called 36 inch) where your deck surface sits 1.8 m (6 ft) or less above grade, and 1,070 mm (42 inches) above that. No gap in the guard can let a 100 mm (4 inch) sphere pass through, and a guard is required at all once the deck surface is more than 600 mm (24 inches) above grade.
Wood Deck Railing
Wood deck railing is the cheapest option up front, and it still suits a cabin or craftsman-style home better than anything else here. The tradeoff is annual staining and sealing, and the Okanagan’s dry summers and swings from -15C to 35C crack and check wood faster than most climates. It’s a fine choice if you’re handy with a stain brush and don’t mind the upkeep.
Composite Deck Railing
Composite deck railing makes the most sense if you already have composite decking and want everything to match. No staining or sealing, and it resists rot and insects, but it’s heavier than aluminum and solid profiles block the view just as much as a picket would. We don’t install it ourselves.
Cables for Deck Railing
Cables for deck railing give you a near-clear view at a lower cost than glass, which is why they’ve gotten popular on contemporary Kelowna and West Kelowna builds. Cables need periodic tensioning as they stretch, and some municipalities flag horizontal runs as a climbing hazard for kids, so check with your building department first. We’ve worked alongside cable installers without installing the systems ourselves.
Vinyl shows up on a lot of decks too, usually where budget matters more than the view. It doesn’t need painting, but it can look plasticky up close and gets brittle faster in our dry heat than most sellers admit. If low upfront cost is the whole goal, we’d still point you at aluminum for the long run.
Installing Decking Rails: Mistakes We Get Called to Fix
- Wood posts buried in snow all winter. Snow sitting against the base rots the post from the bottom up, right where you can’t see it.
- Cable spacing that fails the sphere test. If a 100 mm ball fits through, it fails inspection. Measure before you build, not after.
- White aluminum frame on a lake view. The frame becomes what you notice. A slim black frame disappears instead.
- Composite railing on a span it can’t support. Composite is heavier than aluminum and needs reinforced framing on longer runs.
- Guard height measured from the wrong point. It’s measured from the deck surface, not the ground, and the 1.8 m threshold catches people off guard every year.
Deck Posts and Railings: Which Material Fits Your Deck?
After building deck railings across Kelowna, West Kelowna, Vernon, Penticton and Lake Country for years, the decision usually comes down to two questions: do you have a view worth showing, and how much maintenance are you willing to do? Here’s how we’d point you.
| Your deck | Go with |
|---|---|
| Faces a lake or mountain view | Glass, frameless or semi-frameless |
| Faces a backyard or a fence | Aluminum |
| You want zero annual maintenance | Aluminum or glass |
| You already have a composite deck | Composite, to match |
| Budget is the main driver | Wood or vinyl, eyes open on upkeep |
| You want a modern look under glass pricing | Cable, with posts anchored for tension |
A hybrid works too. We’ve put glass on the view-facing side of a deck and aluminum on the rest, keeping the sightline where it matters and the cost down everywhere else.

Deck Railing Materials Questions
What are the best railing materials for decks?
For most Okanagan decks, aluminum and glass are the best deck railing materials. Aluminum needs almost no upkeep and never rusts, while glass is the only material that doesn’t block your view. Wood, composite, cable and vinyl all have their place, but each asks more of you in maintenance, tensioning or view obstruction.
Which decking balustrade solutions require the least maintenance?
Aluminum and composite require the least maintenance of the six options here. Aluminum needs an annual soapy-water wash and nothing else. Glass needs more frequent wiping to stay clear, cable needs periodic tensioning, and wood needs annual staining and sealing, by far the most work of the group.
What’s the Difference Between Aluminum Deck Railing and Deck Glass Railing?
Aluminum deck railing uses heavy-gauge pickets that are nearly maintenance-free but block part of your view. Deck glass railing uses 12 mm tempered glass in a frameless or semi-frameless frame that disappears entirely, so it’s the better pick on a lake or mountain view. Plenty of our Okanagan decks use both, glass on the view side, aluminum on the rest.
Are cables for deck railing allowed under BC code?
Yes, as long as the spacing stops a 100 mm (4 inch) sphere from passing through, and the guard meets the standard 900 mm or 1,070 mm height. Some municipalities look more closely at horizontal cable runs because they can be climbed, so call your local building department before you commit to a cable system.
How do you attach deck railing to meet BC code height rules?
Guard posts need to be anchored into the deck framing, not just the decking boards, at the required height: 900 mm where the deck surface sits 1.8 m or less above grade, and 1,070 mm above that. No opening can let a 100 mm sphere through, and height is always measured from the deck surface, not from the ground below it.
Is wood deck railing a good choice for Okanagan decks?
Wood deck railing works if the budget is tight and you don’t mind annual staining and sealing. It’s the cheapest option up front and suits a rustic or cabin-style home well, but the Okanagan’s dry heat and winter freeze-thaw cycles are harder on wood than most climates.
