Hardwood decking is what you build when you want the deck to outlast the reason you built it. A dense tropical hardwood resists rot, decay, fungus and insects because of what it is, not because of what was pumped into it — no pressure treatment, no copper, nothing to leach out or wear off. It holds less surface heat than dark composite, keeps its footing wet, and it can be refinished any number of times over a life measured in decades.
Ghent stocks five hardwood decking species: Red Balau, Golden Balau, Korina, Doju, Ipe. All of them are kiln-dried, all of them are S4S with eased edges, and all of them are priced by the lineal foot in even lengths from 8′ to 20′ — so you order the exact tally your deck needs instead of buying square footage you throw away.
The table below is the comparison most people actually come here to make. Everything in it is measured, and the prices are the live catalog price for the 5/4x6 board — the standard residential deck board, and the one profile every species shares.
Compare all five hardwood decking species
| Janka | Density | Radial shrink | CITES | Color | 5/4x6 from | |
|---|---|---|---|---|---|---|
| Red Balau (Batu) | 2,100 lbf | 850 kg/m³ | 6.3% | No | Russet red-brown, mahogany | $3.99/LF |
| Golden Balau (Bangkirai) | 1,798 lbf | 930 kg/m³ | 4.2% | No | Golden brown, ages to mahogany | $3.99/LF |
| Korina (thermally modified) | 670 lbf | 573 kg/m³ | Under 2% | No | Golden to chocolate brown, through the board | $5.35/LF |
| Doju | 3,680 lbf | 950 kg/m³ | 3.6% | No | Olive brown with grey contrast | $6.73/LF |
| Ipe (Brazilian Walnut) | 3,680 lbf | 1,050 kg/m³ | 6.6% | Yes, since 2022 | Deep brown to near-black | $9.25/LF |
Radial shrinkage is the column to read if you have been burned before. It governs how much each board moves across its width through a season — the movement that opens gaps and pulls fasteners. It is the reason Doju and Korina outperform Ipe on stability despite Ipe being the harder, denser board, and the reason quartersawn Golden Balau behaves better than its tangential figure suggests.
CITES Appendix II matters to your schedule rather than your deck. Ipe was listed at the end of 2022, so every shipment now needs export permits and source-country documentation — paperwork we handle, but it moves both price and lead time. Nothing else on this table carries it.
The five species, and what each one is for

Red Balau (Batu)
Best for: A whole deck in one species — rail, stairs and siding included
The mahogany look, the widest range of matching parts we stock — 19 profiles from deck board to porch ceiling — and the easiest of the tropical hardwoods to actually install. Fire-tested to Class A.

Golden Balau (Bangkirai)
Best for: The best value in a genuine tropical hardwood
Also sold as Yellow Balau or Bangkirai. Knot-free, predominantly quartersawn, and about half the cost of Ipe — the species we recommend for the majority of residential decks.

Korina (thermally modified)
Best for: Maximum stability, and no chemicals of any kind
Heat and steam instead of preservatives. Movement falls below 2% in both directions and the brown runs through the whole board. The stable choice — but never structural.

Doju
Best for: Ipe performance without the CITES paperwork
A close cousin to Ipe: identical 3,680 Janka, better dimensional stability than Ipe, and no CITES listing — so supply and lead times stay steady. Our pick for close-to-ground decks.

Ipe (Brazilian Walnut)
Best for: The longest-lived deck money buys, plus a Class A fire rating
The benchmark every other decking species is measured against. 40–75 years untreated, Class A fire rated, and the wood the Atlantic City and Coney Island boardwalks were built from.
Which one should you buy?
Nearly every conversation we have about hardwood decking comes down to three things: what colour you want, what you can spend, and how much the deck has to survive. Here is how we answer it.
- If you want the best value in a real tropical hardwood — Golden Balau or Red Balau, at around $3.99/LF for the 5/4x6. Golden if you want honey-gold, Red if you want mahogany. They cost within pennies of each other and either will outlast a treated-pine deck several times over.
- If the deck has to include rail, stairs, fascia and a porch ceiling — Red Balau, without much argument. It is the only species we carry in all of those profiles, so the whole structure is one wood and weathers as one wood.
- If the deck sits low to the ground, or you are somewhere the seasons swing hard — Doju. Low decks dry poorly from underneath, which is exactly where dimensional stability earns its money, and Doju is the most stable board on the table at Ipe-level hardness.
- If you want zero chemicals and maximum stability, and the deck is a surface rather than a structure — thermally modified Korina. Under 2% movement, colour through the board, nothing added but heat and steam.
- If it has to last longer than you will own the house, or it has to pass a wildland-urban-interface fire code — Ipe. 40–75 years untreated and a Class A flame-spread rating, the same class as concrete and steel. Order early; the CITES paperwork makes supply move.
Still deciding? Order sample boards — they are $5 each from any product page. A golden-brown and a red-brown look nothing alike in your own light, and no photograph settles it. Our interactive decking comparison puts every species we carry side by side on the specs.
A 25-year warranty, and someone to honor it
Every naturally durable hardwood we sell — Ipe, Golden Balau, Red Balau and Doju — carries a 25-year manufacturer warranty against rot and decay, provided the installation guidelines are followed.
Ghent stands behind it as well. If the manufacturer is ever not there to honor a claim, we will. That is the part most warranties leave you to worry about, and it is why we are comfortable putting a 25-year number in writing.
Thermally modified Korina is a different product with a different claim — properly installed thermally modified wood is generally expected to give 25–30 years or more in exterior service. Ask us and we will give you the specifics rather than a number that sounds good.
Hardwood vs composite vs pressure-treated
| Tropical hardwood | Composite | Pressure-treated pine | |
|---|---|---|---|
| Lifespan | 25–75 years depending on species | 25–30 years | 10–15 years |
| Hardness | 1,798–3,680 lbf | n/a — plastic and wood flour | ~870 lbf |
| Chemicals | None | None, but it is plastic | Copper-based preservative |
| Refinishable | Yes, indefinitely | No — scratches are permanent | Yes, with sealing |
| Surface heat | Lower | High on dark colors | Lower |
| If left alone | Silver-gray patina, no loss of strength | Fades, cannot be restored | Grays and degrades |
| Maintenance | Oil every 1–3 years, or nothing at all | Wash | Seal yearly |
| Up-front cost | $$–$$$$ | $$$ | $ |
| Cost per year of service | Lowest of the three | Middle | Highest |
Sizes, lengths and how we price decking
Deck boards are sold by the lineal foot, by length — not by the square foot and not in random bundles. Build your tally on any product page and the calculator totals the feet, the coverage and the price as you go, so you can order the exact mix of lengths your framing wants instead of cutting 20% of a bundle into offcuts.
- 5/4x6 — net 1″ × 5-1/2″, about 0.46 SF of coverage per lineal foot. The standard residential deck board and the thickness most joist layouts are designed around.
- 5/4x4 — net 1″ × 3-1/2″, about 0.29 SF per LF. Tighter board lines, better behaviour on curves and small landings.
- 1x6 and 1x4 — net 3/4″. Lighter boards for tight joist spacing, porch floors and ceilings.
- Grooved profiles in Ipe, Red Balau and Korina, milled for hidden-clip systems.
- 2x4, 2x6, posts, handrail, balusters, bullnose stair treads and fascia in Red Balau, for a deck built entirely from one species.
Lengths run even, 8′ through 20′, depending on species and profile. Long boards matter more than people expect: a 20′ run with no butt joint is one fewer seam to trap water and one fewer place for the deck to look built rather than made.
Installing hardwood decking
None of this is difficult. It is just unforgiving of the shortcuts that work on softwood, and every callback we have ever heard about traces back to one of these.
- Pre-drill and countersink every face fastener. These boards are dense enough that a screw driven straight in will split the board or snap off. Stainless steel only — plain steel will stain the wood.
- Or skip face fastening. Grooved boards take a hidden-clip system such as the ExoDek QuickClip, which sets the gap for you and leaves nothing on the surface.
- Gap 3/16″ to 1/4″ for drainage and seasonal movement.
- Ventilate underneath. A hardwood deck that cannot dry from below will cup no matter which species it is. This matters more than the species you chose.
- Seal fresh end cuts with a wax-based end sealer — every cut opens end grain the mill had already sealed.
- Acclimate on site for several days, stacked and stickered out of direct sun, before you fasten anything.
- Carbide blades, high tooth count, and expect to sharpen more often than you would on cedar.
Working out quantities? Our calculation help turns deck dimensions into a board count, and the tally calculator on each product page turns that into a length-by-length order.
Exoshield wood stain
THE LONGEST LASTING TRANSPARENT WOOD STAIN EVER PRODUCED
- Longest lasting color and protection out of any wood stain
- Highest amount of UV blocking available
- Up to 800 SF of coverage on hardwoods and up to 450 SF on softwoods
- Low VOC and made of all natural products
- Marine grade components

Exodek Quick clip
The ONLY Hidden Deck Fasteners that Allow Wood to Expand and Contract Naturally. Perfect for Hardwoods like Ipe, Batu, Cumaru, Tigerwood & Mahogany.
Typical deck boards can swell up to 3/16” in width. The ExoDek QuickClip hidden decking fastener will compress to absorb this expansion. When the wood later dries out, the hidden fastener spring clip will move the boards back into place, centered perfectly, and securely fastened to the joist below.

Hardwood decks we supplied
Hardwood decking — common questions
Which hardwood decking species is best?
There is no single answer, which is why the table above exists. Ipe lasts longest and is fire rated; Doju matches its hardness and beats it on stability with no CITES paperwork; Red Balau comes in the most profiles and is the easiest to install; Golden Balau is the best value; Korina is the most stable and entirely chemical-free. Tell us the deck and the budget and we will tell you which.
How much does hardwood decking cost?
It is priced by the lineal foot and varies by species, profile and length. For the standard 5/4x6 board the range across our five species runs from about $3.99 to $9.25 per lineal foot. Live pricing for every size is on each product page — nothing on this site is a "call for price".
Is there a warranty?
Yes. Ipe, Golden Balau, Red Balau and Doju all carry a 25-year manufacturer warranty against rot and decay when the installation guidelines are followed — and Ghent stands behind it if the manufacturer is ever not there to honor a claim. Thermally modified Korina is a different product with a different claim; ask us for the specifics.
What is Doju, and why have I not heard of it?
Doju is a dense South American hardwood traded in Europe for decades under its own name rather than as a substitute for anything. It is a close cousin to Ipe — the same 3,680 lbf Janka hardness, better dimensional stability, and no CITES listing. It is newer to the North American market, which is the only reason it is unfamiliar. Full profile here.
Do I have to oil a hardwood deck?
No. Left bare, every species on this page weathers to a silver-gray patina with no loss of strength and no loss of the natural decay resistance you paid for. Oiling is purely about colour, and it is reversible in both directions as many times as you like.
Hardwood or composite?
Composite does not rot and never needs oiling, and it cannot be refinished — a scratch or a fade is permanent, and dark boards run hot underfoot. Hardwood costs less per year of service, can be brought back to new at any point in its life, and is a natural material rather than plastic and wood flour. The comparison table above lays it out.
Do you sell Cumaru?
We will source it on request, but we do not recommend it and we do not stock it. In our experience Cumaru checks, warps, cups and moves a lot in service, and it carries the same CITES Appendix II paperwork as Ipe without Ipe’s stability or lifespan. For a value hardwood we would point you at Golden Balau; for Ipe-class performance, Doju.
What about softwood decking?
We stock that too — see softwood decking for Siberian Larch and the cedar and fir options. Softwood costs less up front and asks more of you over the deck’s life.
Can you deliver?
Yes — we ship hardwood decking nationwide, and quote freight on the real dimensions and weight of your order rather than a flat guess. Send us the tally and the delivered price comes back with it.
