Once the grill is chosen, the next question on every outdoor kitchen project is what the box around it is made of. For most of our clients it comes down to powder-coated aluminum cabinetry, stainless steel cabinetry, or a masonry island fitted with stainless doors and drawers. We sell and install all three across Queens, Long Island, Westchester, New Jersey and the Palm Beach to Stuart stretch of Florida, so this is not a sales pitch for one material. It is the comparison we walk through at the showroom, with the islands and storage components we actually stock.
The short answer
Powder-coated aluminum cannot rust, weighs a fraction of steel, comes in colors, and is the right call for roof decks, coastal Long Island and Florida. Stainless is heavier, harder, and the classic look, but standard 304 will tea-stain and pit near salt water; specify 316 within a few miles of the coast. A masonry island with stainless doors and drawers is the most permanent and the most customizable, and the slowest to build.
Key takeaways
- Aluminum cannot rust; it oxidizes into a protective layer. Stainless resists rust through a chromium film that salt attacks, so grade matters: 304 inland, 316 within a few miles of the ocean.
- "Powder coated" does not tell you the metal underneath. Challenger is aluminum; Brown Jordan and Danver are powder-coated stainless. Ask.
- Aluminum is about a third the weight of steel, which is why it is the answer for roof decks, terraces and anywhere without crane access.
- Both metals are non-combustible, so neither needs the insulated jacket a wood-framed island requires; vent panels are still required wherever gas sits inside a cavity.
- Pick the material for the salt, not the snow. Cold does nothing to either metal; a bayside yard in Massapequa corrodes more than a Scarsdale yard in a decade.
- Masonry with stainless components is the most customizable and permanent path, and the slowest; order every component before the mason frames.

What are the three ways to build the box?
| Approach | What it is | Examples we stock | Strongest where |
|---|---|---|---|
| Powder-coated aluminum cabinetry | Welded aluminum cabinet boxes with a baked powder coat, joined on site, real drawers and doors | Challenger Coastal islands; Blaze Sunset and Golden Hour islands (Urban Bonfire aluminum cabinetry) | Coastal sites, rooftops, color-matched designs, fast installs |
| Stainless steel cabinetry or island | 304 (or 316) stainless boxes, either bare brushed or powder coated; prefab stainless islands | Mont Alpi islands; Blaze stainless islands (Danver and Brown Jordan style cabinetry is not stocked online) | Inland yards, the pro-kitchen look, heavy daily use |
| Masonry island with stainless components | Steel stud or block frame, cement board, stone veneer, stone top, stainless doors and drawers set into it | Blaze, Summerset, Twin Eagles, XO and Delta Heat doors, drawers, trash and pantry units | Custom shapes, matching the house, permanent patios |
Brand names confuse this market. Challenger Designs builds powder-coated aluminum cabinetry, and it is what our crews install most. Brown Jordan Outdoor Kitchens and Danver, two names people ask about, build stainless steel cabinetry (304, with 316 available) and then powder coat it in dozens of colors. So "powder coated" does not tell you the metal underneath. Ask. Mont Alpi builds complete prefab islands from 304 stainless with a granite top. The Mont Alpi islands and the Challenger islands are on our site; Danver and Brown Jordan style stainless cabinetry is not, so ask us if a project calls for it.
Which one rusts? Aluminum, 304 and 316 stainless
Aluminum does not rust. Rust is iron oxide; aluminum has no iron in it. What aluminum does is oxidize, forming a thin, hard, self-healing oxide layer that protects the metal underneath. Bare aluminum left outside goes dull grey and chalky; powder-coated aluminum does not, because the coating takes the weather and the oxide layer backs it up if the coating is scratched. This is why aluminum is the standard for boat hardware, patio furniture and coastal railings.
Stainless steel resists rust; it does not ignore it. Stainless relies on a chromium oxide film. Chlorides, which is what salt is, attack that film. The grade decides how well it holds up:
- 304 stainless is roughly 18 percent chromium and 8 percent nickel with almost no molybdenum. It is what nearly every grill, door, drawer and prefab island is made from, and it is fine in most backyards. Near salt water, or where road salt and pool chemicals hit it, 304 develops "tea staining": a brown surface discoloration, followed by pitting if it is left alone.
- 316 stainless adds 2 to 2.5 percent molybdenum, which specifically resists chloride pitting. It costs more because of the nickel and molybdenum content. Metallurgy references suggest 304 for sites more than about 5 miles from the ocean and 316 inside that band. Kalamazoo, which offers both on its grills, says the same thing in plainer terms: 304 is sufficient for most environments, 316 for oceanfront homes.
In practice, almost no outdoor cabinetry is sold in 316 at a price most people will pay. Grills are a different story: Blaze builds marine grade versions of its Premium LTE+ grill and sells a marine grade flame tamer upgrade for its Professional LUX line, and the Blaze Golden Hour 10 foot island pairs that 316L grill with a marine grade aluminum Urban Bonfire cabinet in a gunmetal powder coat under a Dekton top. That combination, aluminum box plus 316 grill, is what we specify for Long Beach, the Hamptons and anything east of the Intracoastal in Florida.
From our install team
Tea staining on 304 is cosmetic at first and it comes off with a stainless cleaner and a nylon pad, in the direction of the grain. Pitting does not come off. If you are on 304 near the water, wipe the doors down with fresh water every couple of weeks in summer and after every nor'easter. It is cheaper than 316.
How do weight, heat near the grill and hardware compare?
Weight. Aluminum is about a third the density of steel. On a ground-level patio that is a convenience: two installers can walk a Challenger Coastal 81 inch island with sink base through a side gate. The 8 foot Coastal package is 93 1/4 inches wide, 25 deep and 36 1/4 high, and it ships as one assembled piece with the trash pull-out, the fridge opening and the grill base already in it. On a roof deck, a Brooklyn terrace or a raised wood deck it is the deciding factor. A stainless island with a granite top and a 32 inch grill is a crane or a stair crew and a structural letter; the same kitchen in aluminum with a thinner porcelain top is a hand carry.
Heat. This is where people worry about aluminum, and the worry is mostly misplaced. Both metals are non-combustible, so neither needs the insulated jacket that a wood-framed island requires; Blaze requires the jacket only when the island is combustible. Manufacturers size the grill bay with the air gap the grill manual calls for, and the grill's own body carries the heat. Where aluminum does differ is thermal conductivity: it moves heat faster than stainless, so a cabinet face next to a grill that runs hot all afternoon will be warmer to the touch. Powder coat is cured at high temperature and handles that. What neither material tolerates is a grill forced into a cutout that is too small, or a side burner installed without the manufacturer's clearance. That is an install problem, not a material problem.
Dents, scratches and hardware. Stainless is harder. A dropped cast-iron skillet dents aluminum more readily than steel, and a scratch through powder coat shows the silver metal underneath until it is touched up. Stainless scratches show too, but they blend into brushed grain. Drawer slides, hinges and pulls on good cabinetry are stainless regardless of the box material; ask what grade the slides are, because that is where coastal rust shows first on cheap product.
Which looks better, and how does each one age?
Aluminum cabinetry is a color decision. Challenger's Coastal line is finished in neutral powder coat tones with a shaker door style that reads like indoor cabinetry next to stone and pavers. Blaze's aluminum islands come in gunmetal and architectural bronze, as on the Blaze Sunset 10 foot island in bronze. Stainless cabinetry from Brown Jordan and Danver is where the 50-plus color charts and wood-grain finishes live, if a designer wants a navy or a white kitchen.
Powder coat lifespan. Powder coat is an electrostatically applied polyester or hybrid powder baked into a continuous film. It is far tougher than paint and resists chipping and fading well, but it is not immune to UV. Darker colors and south-facing installs in Florida will fade a shade over years; textured finishes hide it better than gloss. A quality coat on a properly prepped substrate outlasts any paint by years, and chips are touched up with the manufacturer's kit. Manufacturers typically warrant the finish separately and for a shorter term than the cabinet box; read both terms.
Bare stainless ages by patina. Brushed 304 picks up fingerprints, water spots and, near salt, tea staining. Kept clean it looks the same in year ten as year one. The look is the look: industrial, bright, matches the grill. If you want the grill to disappear into the cabinetry, a brushed stainless island does that better than anything.
Maintenance. Aluminum with powder coat: mild soap and water a few times a season. Stainless: a dedicated stainless cleaner, wiped with the grain, more often near the coast. Both: cover the grill, not the whole island, over winter, so the cabinets can breathe and the covers do not trap moisture against the metal.
Not sure what fits your space? Tell us how far you are from salt water, whether the kitchen sits on grade or a deck, and what color the house is, and we will tell you which material we would put our own name on. Book a free design consultation and we will help you narrow it down.
Which costs more and takes longer?
We do not print prices in a guide because they change, but the order is consistent. A prefab stainless island like a Mont Alpi 400 Deluxe is the lowest total cost for a complete kitchen, because the grill, top and cabinets are one SKU. Powder-coated aluminum cabinetry sized for your own grill, such as the Challenger Coastal 83 inch island for a 32 inch grill and a kamado, sits in the middle and climbs with length and the appliances you drop in. Custom stainless cabinetry from the Danver and Brown Jordan tier is the top of the range, and the masonry route costs whatever the mason and the stone fabricator cost, plus the components.
Lead times follow the same order. Mont Alpi and the stock Challenger Coastal configurations are usually available quickly, and the pre-assembled Challenger packages are built and shipped as a unit. Custom-configured aluminum and any custom stainless cabinetry run several weeks from order. Masonry is a construction schedule: footing, frame, veneer, template, stone, then the appliances, and in New York the gas and electric permits run alongside.
One cost that is easy to miss: the countertop. Challenger Coastal islands ship with an aluminum top that many clients keep; upgrading to granite or porcelain means a template visit and a fabricator. Mont Alpi includes granite. Blaze's Sunset and Golden Hour islands come with a Keon or Aeris Dekton slab already fitted.
Which material holds up in your climate?
| Where you are | What the weather does | Our pick |
|---|---|---|
| NYC, Westchester, inland Long Island and NJ | Freeze and thaw, snow sitting on the top, road salt tracked onto patios | Any of the three. 304 stainless is fine. Keep salt and ice melt off the cabinets. Masonry needs a proper footing or it heaves. |
| South Shore and East End of Long Island, Rockaways, coastal NJ | Salt air every day, wind-driven spray in storms, the same freeze cycle | Powder-coated aluminum cabinetry with a marine grade grill, or 316 stainless if you want bare metal. Rinse 304 components often. |
| Rooftops and terraces anywhere in the city | Weight limits, no crane access, more wind and sun than a yard | Aluminum. It carries up a stair and a lighter top keeps the structural math simple. |
| Palm Beach, Jupiter, Stuart | Salt, humidity, intense UV year round, hurricane season | Aluminum in a lighter color, or 316 stainless. Masonry with stainless doors is common there too; use 316 components near the water and anchor the island. |
The thing that surprises Northeast clients is that winter is not the enemy. Cold does nothing to either metal. Salt does. A Massapequa backyard four blocks from the bay sees more corrosion than a Scarsdale yard sees in a decade, and a Jupiter patio sees more than both. Pick the material for the salt, not the snow.
When is masonry with stainless components the right call?
The built island is how outdoor kitchens were done before modular cabinetry existed, and it is still the right answer when the kitchen has to match a stone house, wrap a curved patio or carry a pizza oven and a 48 inch grill. The frame is steel stud or block, never wood if you can avoid it, skinned in cement board and finished in veneer stone, stucco or brick with a stone top. Into it go stainless access doors and drawers, which is where the stainless question comes back.
Nearly all of these components are 304 stainless. Choose by what you need behind each opening:
- Under the grill: a door and drawer combo sized to the grill. The Blaze 32 inch door and double drawer combo pairs with the Blaze Premium LTE+ 32; the Summerset 33 inch flush mount combo and the XO 42 inch Pro-Grade combo cover other widths. The door gives you the gas valve; the drawers hold tools.
- Trash: a roll-out trash drawer such as the Delta Heat 18 inch double trash drawer.
- Sealed dry storage: a gasketed pantry such as the Twin Eagles 36 inch sealed pantry or the Blaze 32 inch dry storage pantry keeps paper goods dry inside a masonry box that otherwise sweats.
- Vent panels: a masonry island is a sealed cavity. Two Blaze 6 by 14 vent panels on opposing faces, low for propane and high for natural gas, are not optional.
Flush-mount versus raised-frame doors matter more on masonry than on cabinetry. A flush door sits inside the stone with a clean reveal and needs a square, accurate opening; a raised frame overlaps the stone and forgives a rough cut. Tell the mason which you bought before the veneer goes on.
From our install team
Order every stainless component before the mason frames. The cutout sheets ship with the parts, and a door that is a half inch off from the opening is the single most common reason a masonry kitchen stalls for two weeks.

Aluminum and stainless islands
Stainless components for a masonry island
Which should you choose?
Choose powder-coated aluminum if:
- You are within a few miles of salt water on Long Island, the Jersey Shore or in Florida.
- The kitchen goes on a roof deck, a terrace or a raised wood deck where weight and stair access decide the job.
- You want a color that matches the house and a fast, pre-assembled install.
Choose stainless steel if:
- You are inland (Queens, Westchester, central Nassau, Bergen County) where 304 holds up with normal cleaning.
- You want the bright pro-kitchen look where the grill disappears into the cabinetry.
- You want the lowest total cost for a complete kitchen (a prefab Mont Alpi), or the widest color range (Danver and Brown Jordan tier, specified in 316 near the coast).
Choose masonry with stainless components if:
- The kitchen must match a stone house, wrap a curved patio or carry a pizza oven and a 48 inch grill.
- You have a slab or will pour a footing, and a construction schedule does not bother you.
- You are happy with 304 doors and drawers and will rinse them if you are near the water.
For most coastal and rooftop projects we put our name on powder-coated aluminum, usually a Challenger Coastal island or the Blaze Golden Hour with its 316 grill. For an inland yard where budget and speed matter, a Mont Alpi stainless island is the kitchen that gets used the same weekend it arrives. Build masonry when the design demands it, frame it in steel stud, and order the stainless components first. Whichever you pick, choose for the salt, not the snow.

Frequently asked questions
Is aluminum or stainless steel better for an outdoor kitchen?
Neither is better everywhere. Powder-coated aluminum cannot rust, weighs about a third as much as steel and comes in colors, which makes it the pick for coastal sites, rooftops and color-matched designs. Stainless is harder, dent resistant and the classic look, and 304 stainless is fine inland. Near salt water, bare stainless should be 316.
Does aluminum outdoor cabinetry rust?
No. Rust is iron oxide and aluminum contains no iron. Aluminum forms a thin protective oxide layer instead, and the powder coat sits on top of that. Scratches through the coating show silver metal but do not spread the way rust does on steel.
What is the difference between 304 and 316 stainless steel?
316 adds 2 to 2.5 percent molybdenum, which resists the chloride pitting that salt air and pool chemicals cause on 304. Both look the same. 316 costs more. Metallurgy references generally suggest 316 within about 5 miles of the ocean and 304 beyond it.
Will powder coat fade or chip outdoors?
Quality powder coat resists chipping and fading far better than paint, but strong year-round sun, especially on dark colors in Florida, will soften the color over many years. Chips are touched up with the manufacturer's kit. Expect the finish warranty to be shorter than the cabinet warranty.
Can I put a gas grill directly into aluminum cabinetry?
Yes, in cabinetry designed for it. Aluminum and stainless are both non-combustible, so the insulated jacket required for wood-framed islands is not needed. The grill bay must match the grill manufacturer's cutout and clearance dimensions, which is why we size the cabinet to the specific grill.
What stainless grade are access doors and drawers?
Almost all built-in doors, drawers, trash pull-outs and pantries from Blaze, Summerset, Twin Eagles, XO and Delta Heat are 304 stainless. Near the water, rinse them with fresh water regularly and clean tea staining with a stainless cleaner before it pits.
Which is best for a Long Island beach house?
Powder-coated aluminum cabinetry with a marine grade (316) grill, such as a Challenger Coastal or Blaze Golden Hour island paired with a Blaze marine grade grill. If you want bare stainless, specify 316 for the grill and plan on regular rinsing of any 304 components.
Do I still need vent panels with metal cabinetry?
Yes if there is gas inside an enclosed cavity. Check the island manual for where its openings are, and add vent panels to any masonry island, low for propane and high for natural gas, per the grill manual.
