Weather-Resistant Outdoor Furniture: Aluminium vs Resin
How aluminium and resin each handle sun, rain and salt air, plus where teak, rope and Sunbrella fit in.
Outdoor Furniture Ideas · 9 min read

Aluminium and resin are the two most weather-resistant materials for Australian conditions, for different reasons.
The most common question when buying outdoor furniture is a simple one: which material actually survives being left outside? Two rise to the top for weather resistance, aluminium and polypropylene resin, and this guide compares them head to head. Then it widens out to teak, rope and Sunbrella, so you can match the material to your space with confidence. Whichever way you lean, you can browse it by material, from aluminium outdoor furniture to resin outdoor furniture.

No. 01
Aluminium: Strengths and Trade-Offs
Aluminium is the go-to metal for outdoor furniture because it does not rust. That single property makes it the safest choice for coastal and high-humidity homes, where salt air corrodes lesser metals quickly.
- Rust and corrosion proof. It will not warp, rot or rust, unlike timber or iron, so it holds up in rain, wind and salt air.
- Lightweight. Easy to move, rearrange and store, and suited to balconies and rooftops with weight limits.
- Powder-coated for the sun. A quality powder-coat resists fading and chipping under Australian UV and comes in a wide range of finishes, including wood-grain and textured looks.
- Low maintenance and recyclable. A wash with soapy water keeps it looking new, and aluminium is fully recyclable.
The trade-off: bare metal can get hot in direct sun, so powder-coated frames and some shade matter for comfort.
No. 02
Polypropylene Resin: Strengths and Trade-Offs
Modern polypropylene resin is nothing like the brittle plastic of the past. Quality resin, like the Italian-made Nardi ranges, is engineered specifically for the outdoors.
- UV-stabilised. It holds its colour and strength under prolonged sun without fading, cracking or becoming brittle.
- Weatherproof and low-care. It will not absorb moisture or grow mildew, and cleans up with a hose. No sealing or refinishing.
- Stackable and versatile. Lightweight and often stackable, in a broad palette of colours and shapes to suit any space.
- Recyclable. High-quality resin is fully recyclable at end of life.
The trade-off: being lightweight, resin chairs can shift in strong wind on exposed sites, and the look is a little more casual than metal or timber.

Aluminium vs Resin at a Glance
| Aluminium | Polypropylene resin | |
|---|---|---|
| Rust / corrosion | Will not rust | Not applicable, will not corrode |
| UV / fading | Powder-coat resists fading | UV-stabilised, holds colour |
| Weight | Light, stays put better | Very light, can shift in wind |
| Maintenance | Soapy water, towel dry | Hose off, no sealing |
| Best for | Coastal, structured looks | Balconies, colour, stacking |

Aluminium suits structured, coastal settings; resin excels where colour and stacking matter.

Beyond the Two: Teak, Rope and Sunbrella
Aluminium and resin cover most needs, but three other materials earn their place depending on the look and position you are after.
- Teak. The gold standard in timber. Natural oils resist water, rot and insects, and it settles into a silver-grey patina, or stays golden with an annual oil. It is heavier, so it suits a stationary teak outdoor furniture setting rather than pieces you move often.
- Rope. UV-stable synthetic rope has an open, breathable weave and a soft, contemporary look. It is best in covered or semi-shaded spots and usually pairs with an aluminium or teak frame for structure.
- Sunbrella fabric. Solution-dyed outdoor fabric resists fading and mildew, so cushions can live outside. It pairs with both aluminium and resin frames to add lounge comfort without the upkeep of indoor fabric.

Which Material Suits You?
Use your position and how you live outdoors as the filter.
| Your situation | Best-suited material |
|---|---|
| Full-sun position | UV-stabilised resin or powder-coated aluminium |
| Coastal / salt air | Aluminium or teak |
| Small balcony | Stackable resin |
| Covered or semi-shaded patio | Rope on aluminium, or teak |
| Need to move and store it | Aluminium or resin |
“Aluminium for structure and the coast, resin for colour and easy care. Both outlast the cheap furniture they replace.”
Know Before You Buy
Materials to Avoid
Some materials struggle outdoors year-round. Unless you can store and maintain them, keep these to covered areas only.
- Untreated softwoods. They swell and rot without regular sealing.
- Natural wicker and rattan. They degrade fast in rain and humidity. For the woven look outdoors, choose UV-stabilised resin instead.
- Iron and untreated steel. Strong but quick to rust, especially near the coast.
