Two metals that termites cannot eat and humidity cannot swell — but they are not interchangeable. Here is what each costs per foot run, how they behave over a wok burner, and where a tiled concrete base still beats both.
Both stainless steel and aluminium exist in Malaysian kitchens for the same reason: they are inorganic. Termites cannot eat them, humidity cannot swell them, and a leaking trap under the sink does not turn them into a soft, smelly ruin. In a country where the two commonest cabinet complaints are kembang and anai-anai, that alone is a strong argument. The question is which metal, and the answer usually comes down to how hard the kitchen is worked.
Aluminium at RM400–RM700 per foot run is the volume choice: lighter, cheaper, available in powder-coated colours and convincing wood-grain finishes, and easy to fabricate into a full kitchen. Stainless steel at RM650–RM1,000 per foot run is the heavy-duty choice: stronger, genuinely heat-tolerant, hygienic enough for commercial and clinical use, and effectively permanent — at a price that only makes sense where the kitchen is punished. If you are comparing metal against timber-based cabinets rather than metal against metal, start at the aluminium kitchen cabinet cost guide.
A stainless cabinet is a carcass and doors folded from steel sheet, usually over an internal frame, with the visible faces in a brushed or hairline finish. The critical specification is the grade. Grade 304 is the usual choice for kitchen surfaces because its chromium and nickel content gives it good resistance to the acids, salt and moisture a kitchen throws at it. Cheaper grade 201 substitutes manganese for much of the nickel; it costs less and is more prone to surface tea-staining and pitting in humid, coastal or chlorinated air. Neither is “stainless” in the sense of being unable to mark — the term describes resistance, not immunity.
Sheet thickness is the second specification, and it is what separates a solid cabinet from a tinny one. Thin sheet oil-cans — it flexes and pops under hand pressure — and dents on the first trolley knock. Ask which grade and which sheet gauge is quoted, and ask whether the doors are single-skin or a double-skin panel with an infill, because a double-skin door is dramatically quieter and stiffer. Ask, too, what the internal frame is: some “stainless” kitchens are a stainless skin on a timber or particleboard core, which reintroduces every problem you were paying to avoid.
A full aluminium kitchen is built from extruded aluminium profiles making up the frame, with panels — aluminium composite, solid sheet, or glass in a framed door — filling them. The doors are the part most people recognise: the 3G, 4G and 5G framing systems that dominate Malaysian showrooms are all aluminium door constructions, and they are covered in detail in the 3G vs 4G vs 5G guide.
Aluminium’s corrosion resistance works differently from stainless steel’s. It oxidises instantly on exposure and that thin oxide layer protects everything beneath it — which is why bare aluminium does not rust in the way steel does. On top of that, cabinet aluminium is almost always powder-coated or given a wood-grain thermal-transfer coating, so the metal you see is a coated surface, not raw metal. The coating is the wear layer: it is what fades, chalks or scratches, and it is what you should ask about. Aluminium is also the softer metal, so it dents more readily than a decent stainless sheet, and it conducts heat readily, which matters right beside a burner.

Aluminium overlaps heavily with a good plywood-and-laminate kitchen at RM350–RM600 per foot run, which is the real decision most households face — and the ten-year answer usually favours the metal in a wet kitchen and the timber-based build in a dry one. Put whichever you choose against the whole-kitchen budget in the kitchen cabinet cost guide.
This is the round both metals win against timber-based cabinets, but they win differently. Aluminium does not rust; its oxide layer is self-repairing, so a scratch through the powder coat does not start a spreading corrosion front the way it does on steel. What aluminium dislikes is galvanic contact — aluminium bolted directly to dissimilar metal in a wet environment corrodes at the join — and prolonged contact with wet cement or lime, which attacks it. Both are installation details rather than material flaws.
Stainless steel resists corrosion through its passive chromium oxide film, and it repairs itself too, provided oxygen can reach the surface. Where it gets into trouble is under things: a wet cloth left folded on a shelf, a steel wool pad left on a counter, or standing water in a corner starves the surface of oxygen and leaves a rust-coloured stain. Iron particles from the wool pad are the classic cause of what looks like “rusting stainless” and is actually contamination sitting on the surface. Neither metal cares about a leaking trap the way a particleboard box does — but fix the leak anyway, because the countertop and the wall behind still do.
Here stainless steel pulls clearly ahead. It tolerates direct heat that would blister a powder coat or a laminate face, which is why commercial kitchens are made of it and why a stainless surround beside a high-output burner is a genuinely practical choice in a Malaysian wet kitchen. Grease wipes off it, degreasers do not harm it, and nothing on its surface can scorch or discolour permanently the way a resin-based finish can.
Aluminium handles a hot kitchen well but not direct flame contact: sustained high heat can discolour or blister a powder-coated finish, and the metal conducts heat quickly, so a panel immediately beside a burner gets hot to the touch. That is a comfort and finish issue rather than a safety one, but it argues for a stainless or tiled surround at the hob even in an aluminium kitchen. Both metals are non-combustible, which is one quiet advantage over any timber-based cabinet in a room with an open flame — and if you cook with a gas cylinder, the ventilation requirements for the cylinder cabinet are their own topic and should follow your gas supplier’s and Suruhanjaya Tenaga guidance rather than a showroom’s.
| Everyday factor | Stainless steel | Aluminium | Concrete base with metal doors |
|---|---|---|---|
| Dent resistance | Good in a proper gauge | Softer — dents more easily | Base is immovable; doors as per metal |
| Noise | Can clatter; needs dampers | Lighter, thinner, more resonant | Quietest — mass absorbs sound |
| Fingerprints | Very visible on brushed faces | Depends on coating; wood-grain hides most | Depends on tile and door choice |
| Colour options | Essentially one | Wide — colours and wood grains | Tile choice is wide |
| Cost per foot run | RM650–RM1,000 | RM400–RM700 | Wet works plus doors — quoted per job |
The two complaints that actually reach us about metal kitchens are noise and fingerprints, not durability. Both are solvable: soft-close hinges and buffer pads take the clatter out of doors, drawer boxes with dampers take it out of runners, and a wood-grain or textured coating on aluminium hides marks that a mirror-brushed stainless face advertises. Ask the showroom to open and close a door hard before you buy — that sound is what you will live with.
“Outdoor cabinets” in the Malaysian context usually means a covered back porch, a rear service yard or an extended wet kitchen that is roofed but open at the sides — not genuinely exposed. That distinction matters enormously, because a covered installation and an exposed one are different projects.
The failure most people do not anticipate outdoors is the hardware, not the box. Ordinary hinges and runners corrode long before an aluminium carcass does, so specify stainless or purpose-rated hardware and expect to service it. Getting the roof and drainage right first is what makes the rest last.
The traditional Malaysian wet kitchen is not a cabinet at all. It is a brick or reinforced-concrete base, rendered and tiled, carrying a cast or tiled counter, with doors hung on the front to close off the storage underneath. Those doors are increasingly aluminium or PVC rather than timber, and the combination is quietly one of the most durable kitchens you can build in this climate: nothing under the counter can swell, termites have nothing to eat in the structure, a lesung batu can be used on the counter without anyone flinching, and the whole thing shrugs off water.
The trade-offs are equally real. It is permanent — changing the layout means demolition, not unscrewing. Drawers are difficult, so storage tends to be deep open cavities behind doors, which is less usable than a drawer stack. It needs wet works, curing time and a competent tiler, so the programme is longer than a cabinet installation. And grout lines need cleaning. It pairs naturally with a poured or tiled counter rather than engineered stone — the cost comparison against quartz and sintered stone is in the quartz countertop price guide. A common and sensible compromise is a concrete base in the wet kitchen and conventional cabinetry in the dry one.
Metal doors weigh more than melamine ones, and hinges are rated by load. Under-hinged heavy doors sag, and a sagging door misaligns against its neighbour, which is the single most common metal-kitchen complaint after noise. The fix is specification, not brand loyalty: enough hinges for the door’s weight and size, mounted into the frame properly. What that costs, and how to fix doors that have already dropped, is covered in the soft-close hinge price and repair guide.
Repairability differs between the two metals. A dented or scratched stainless panel can often be blended by a metalworker, and a badly damaged panel can be replaced without touching the frame. Aluminium’s powder coat cannot really be spot-repaired to an invisible finish, so a deep scratch means living with it or replacing the panel — another argument for wood-grain and textured coatings, which disguise damage far better than a flat gloss colour. In both cases, ask before you buy whether individual doors and panels can be reordered later, and note the profile system used.
Stainless steel dominates commercial and clinical settings for reasons that also apply at home. It is non-porous, so there is nothing for bacteria to soak into; it tolerates strong degreasers and hot-water cleaning that would strip a coated surface; welded joints can be made seamless, removing the crevices where grease and pests accumulate; and it does not absorb odour. Coved, seamless corners and legs that lift the unit off the floor are the details that make a stainless kitchen genuinely cleanable rather than merely metallic.
For a home cook who fries hard daily, that translates into a practical hybrid: a stainless run at the cooking and washing zone, aluminium or laminate elsewhere, and a countertop chosen for heat rather than looks in that one stretch. If you are specifying for a commercial unit, a cafe or a food business rather than a home, the fit-out considerations sit alongside the commercial fit-out conversation and the standards your local authority applies.
Choose aluminium if you want a metal kitchen at a sensible price, care about colour and wood-grain options, are fitting a normal domestic wet kitchen, or are working in a termite-prone landed home where timber is the risk you are buying out of. Choose stainless steel if you cook hard and hot every day, want a surface that cannot scorch, need a genuinely cleanable food-prep environment, or are fitting a commercial or semi-outdoor kitchen where the extra spend is repaid in service life. Choose a concrete base with metal doors if the layout will never change, you want the cheapest genuinely permanent wet kitchen, and you are comfortable with wet works.
The most common good answer is a mix. Metal where it is wet and hot, timber-based cabinetry where it is dry and seen, and the money spent on the carcass rather than the door face — because the box is what fails.
