The teak-or-aluminium question comes up in almost every commercial specification, and it is usually framed as a matter of taste. It is not. It is a decision about weight, maintenance ownership, colour consistency across phased purchases and how the furniture behaves in a specific micro-climate. This guide is written for procurement directors, FF&E buyers and landscape architects specifying for hotels, resorts and multi-residential developments, and it deliberately ends with a recommendation to use both.
The short answer
Choose solid teak where guests touch the furniture, where the natural warmth is part of the design intent, and where the property will accept a cosmetic colour change. Choose powder-coated aluminium where the furniture will be moved constantly, where weight matters structurally, where the property will not run a maintenance programme, and where a reorder three years later must match the original exactly.
Solid teak: what you are actually buying
Why it survives
Teak carries a high natural oil and silica content. The oil resists moisture ingress and fungal growth; the silica makes the surface hard-wearing and gives it the slightly abrasive feel that makes it comfortable wet. It is one of very few timbers that can be left outside, unfinished, for decades and remain structurally sound. That is not marketing — it is why historic teak decking is still in service.
What it costs you over time
Left alone, teak weathers from honey to an even silver-grey over roughly nine to eighteen months depending on UV exposure. This is a surface change only and does not affect strength. If the design intent requires the original tone, budget for a water-based teak sealer once or twice a year. Never use bleach or a high-pressure washer — both destroy the surface fibres and accelerate greying rather than preventing it.
Teak is also heavy. On a roof terrace or a suspended slab, weight may be a structural constraint rather than a preference, and this is often the deciding factor that has nothing to do with appearance.
Powder-coated aluminium: what you are actually buying
The coating is the product
With aluminium, the frame is only as good as its pre-treatment and coating. Frames should be degreased and chromate pre-treated before the powder is applied and cured, so the coating keys into the metal chemically. Done properly, a finish survives scratch-and-salt exposure for years; done poorly, it starts lifting at the weld edges after two seasons. When you compare quotes, you are often comparing pre-treatment, not powder.
Weight, handling and repeatability
Aluminium is roughly a third of the weight of an equivalent teak frame, which matters for any area that gets re-set daily — pool decks, rooftop bars, event lawns and restaurant terraces that flip between layouts. It needs no oiling, sealing, sanding or varnishing: a freshwater rinse a few times a season and a mild soap wash is the entire maintenance list.
It is also uniquely repeatable. Because a RAL number is a number, a reorder in year three matches the year-one delivery without the natural variation you get when specifying timber. For properties phasing a purchase across multiple budget cycles, that consistency is worth more than it appears on a spreadsheet.
Side-by-side comparison
| Consideration | Solid teak | Powder-coated aluminium |
|---|---|---|
| Weight | Heavy — check slab loading on roofs | Approx. one third of teak |
| Maintenance | Optional sealing for colour; no structural need | Rinse and mild soap wash only |
| Appearance over time | Weathers to silver-grey (cosmetic) | Stable; no colour change |
| Colour consistency on reorder | Natural variation between batches | Exact match via RAL number |
| Coastal / salt air | Excellent — natural oil content | Excellent with 316 stainless fixings |
| Best for | Statement pieces, loungers, guest-contact areas | High-turnover dining, rooftops, staff-moved items |
Where each one belongs on a property
A useful way to allocate is by turnover rather than by aesthetics. Teak belongs in the areas where guests linger and touch: pool loungers, daybeds, the villa terrace, the sunset deck. Aluminium belongs wherever staff move furniture daily: the breakfast terrace, the rooftop bar, the event lawn, the poolside dining set that is stacked and re-set every evening.
On a typical resort this produces a split of roughly 40/60 in favour of aluminium by piece count, and closer to 60/40 in favour of teak by visual impact — because the teak sits exactly where the photographs are taken.
Specifying both into one container
This is more common than buyers expect and it is not administratively difficult. Because we build both materials in-house, we issue one loading plan and one set of documents for a mixed shipment, and we can weight the packing so the heavy teak and the lighter aluminium balance correctly in the container. Mixing also lets you test a material choice on a small area before committing the whole property — order a handful of aluminium dining sets alongside the teak loungers, run them for a season, and let the maintenance team tell you which one they prefer before the second container.
Questions buyers ask us most
Can aluminium look warm enough for a five-star property?
Yes, but it needs specifying. A wood-grain or textured powder finish over a warm RAL base reads very differently to a flat grey, and pairing aluminium frames with teak arm caps or table tops gives the tactile warmth at the point where guests actually touch the furniture. The frame can be aluminium while the surfaces people notice are timber.
Will teak really last outdoors without any treatment?
Structurally, yes — the natural oil and silica content is what makes teak one of the few timbers that can be left unfinished outside for decades. What changes is appearance: it moves from honey to silver-grey over roughly nine to eighteen months. If that is acceptable to the design intent, teak needs no treatment at all beyond cleaning.
Which one is actually cheaper?
Up front, powder-coated aluminium is usually the lower unit cost. Over a ten-year service life the comparison narrows considerably, because teak's higher initial price is offset by a very long service life and strong salvage value, while aluminium's lower price comes with a finish that is eventually the wearing surface. The honest answer is to price both against your replacement cycle rather than against each other.
Can we use both and still get one warranty?
Yes. When both materials come from the same factory, one warranty and one spares schedule cover the whole shipment, and the loading plan accounts for both. Mixing across two suppliers is where mixed-material projects become administratively painful — not the mixing itself.
Questions worth asking before you choose
- Is there a slab loading limit on any terrace or roof in scope?
- Who owns furniture maintenance after handover — and will they actually do it?
- Will this purchase be phased over more than one budget cycle?
- Is the site coastal, and if so how exposed to salt spray?
- How often will staff move each piece?
Answer those five and the material decision usually makes itself. If you would like us to work through them against your drawings, send the areas and quantities and we will come back with a material allocation, trade pricing and 3D files for each position — usually within one working day.
