Choosing between an aluminium picnic table and a hardwood picnic table is one of the most common questions we field from facilities managers, councils, and commercial buyers in Australia. Both materials work outdoors. But they work differently, and for Australian conditions in particular, the differences matter.
This guide compares aluminium and hardwood picnic tables on every practical dimension: weight, durability, maintenance, aesthetics, cost, sustainability, lifespan, and repairability. We have built hardwood picnic tables for Australian outdoor environments for years, so the observations here come from direct experience, not marketing copy.
Aluminium Picnic Tables in Australia, Where They Work
Aluminium picnic tables are lightweight, rust-proof, and relatively low cost at the point of purchase. They suit specific installation contexts well:
- Temporary or semi-permanent events: trade shows, markets, festivals, where tables need to be moved frequently
- Marine and coastal industrial environments where salt spray corrosion is the primary risk and aesthetics are secondary
- Weight-sensitive installs: rooftop terraces with load limits, or transport applications where mass is a constraint
- Short-cycle replacement environments: settings where tables are expected to be replaced within 5 to 8 years anyway
Aluminium does not rot, rust, or absorb moisture. For a buyer whose primary concern is zero corrosion in a salt-heavy environment, a marina, a harbour-facing pub, a waterfront council facility, aluminium has a clear advantage over untreated timber.

Hardwood Picnic Tables, Where They Work
Hardwood picnic tables made from Class 1 or Class 2 rated Australian species, Spotted Gum, Ironbark, Merbau, are suited to permanent outdoor installations where longevity, aesthetics, and thermal comfort matter.
- Parks, schools, councils, and public green spaces: where a 20-to-40-year service life is expected and replacement cost is a budget consideration
- Hospitality venues, beer gardens, restaurants, and resorts: where the look of the furniture contributes to the customer experience
- Backyards and residential entertaining areas: where the table is a long-term investment, not a consumable
- High-UV outdoor environments: where aluminium's heat absorption becomes a practical problem (discussed below)
Hardwood carries natural oils that resist moisture, insects, and UV degradation. Class 1 hardwood rated under Australian Standard AS 5604, such as Spotted Gum and Ironbark, is rated for full outdoor exposure in ground contact. A picnic table above ground, oiled annually, will last a generation.
Side-by-Side Comparison Table
| Factor | Aluminium | Hardwood (Class 1-2) |
|---|---|---|
| Weight | Very light, easy to move | Heavy, stable, harder to shift or steal |
| Durability | Rust-proof; dents and scratches visible over time | Rated Class 1-2 (AS 5604); resists rot, insects, UV |
| Aesthetics | Industrial finish; limited warmth | Natural grain; warm tones; preferred for hospitality |
| Maintenance | Wipe-clean; powder coat may fade in UV | Annual oiling (15-30 min per table) |
| Cost (upfront) | Lower initial price for standard sizes | Higher initial cost; lower cost-per-year over lifespan |
| Sustainability | High energy extraction; recyclable at end of life | Sustainably sourced Australian and certified timber |
| Lifespan (outdoor) | 8-15 years before cosmetic degradation | 20-40+ years with basic care |
| Repairability | Welding required; not field-repairable | Boards can be replaced, re-oiled, re-sanded |
For permanent outdoor installations in Australia, hardwood wins on total cost of ownership. For more on how to calculate 10-year cost across materials, see our Hardwood Picnic Table Total Cost of Ownership guide.
Why Hardwood Outperforms Aluminium in High-UV Environments
Australia has some of the highest UV indices in the world. This matters for outdoor furniture in a way that most product specifications do not mention: aluminium gets hot.
Aluminium has a thermal conductivity of approximately 205 W/m·K. In direct summer sun in Queensland, New South Wales, or Western Australia, an aluminium table surface can reach 60-70°C. That is uncomfortably hot to touch with bare hands or to rest bare arms on, and it is a safety consideration for any venue serving children.
Hardwood has a thermal conductivity of approximately 0.12-0.17 W/m·K, roughly 1,000 times lower than aluminium. A hardwood picnic table under the same direct sun will be warm to the touch but not hot. The thermal mass difference is not marginal, it is the difference between a usable table and an unusable one during Australian summer.
This is one reason councils, schools, and parks across NSW, QLD, and VIC consistently specify timber for outdoor public furniture rather than metal. Aluminium may resist corrosion better, but in a high-UV outdoor setting, hardwood is simply more comfortable to use.

Why Aluminium Works Better in Some Situations
It is worth being direct: aluminium is the better choice in a narrow set of circumstances.
- Weight-sensitive rooftop or elevated deck installations where structural load limits preclude a hardwood table weighing 80-120kg
- Industrial or processing environments: food manufacturing, waste facilities, chemical handling areas, where hygiene protocols require wipe-down surfaces and timber grain is considered a contamination risk
- Temporary event hire operations where tables are stacked, transported, and deployed repeatedly and the low weight reduces handling costs
- Short-term budget-constrained projects where the intent is to replace furniture within a 5-year cycle regardless of material
Outside these scenarios, aluminium's advantages, mainly low weight and zero rust, are rarely the deciding factors for a permanent outdoor installation. Most parks, schools, and hospitality venues are not weight-limited, and a properly maintained hardwood table will outlast its aluminium equivalent in nearly every Australian outdoor environment.
Environmental Considerations
Aluminium smelting is energy-intensive. Producing one tonne of primary aluminium requires approximately 14,000-17,000 kWh of electricity, most of which, globally, is sourced from fossil fuels. The end-of-life recyclability of aluminium is a genuine environmental advantage, and aluminium recycling uses approximately 5% of the energy of primary production. But the extraction and manufacturing footprint is large.
Hardwood sourced from certified Australian suppliers, including Spotted Gum and Ironbark from sustainably managed NSW and QLD forests, carries a lower embodied energy per unit. The timber sequesters carbon during the tree's growth period, and a 40-year service life means the carbon stored in the table is retained in service rather than released quickly. Auscraft sources timber from certified suppliers with Chain of Custody documentation available for council and institutional procurement requirements.
For buyers with sustainability reporting requirements, hardwood from certified Australian sources is typically easier to document than aluminium of equivalent quality. For more on this, see our comparison of hardwood with recycled plastic picnic tables, which covers similar sustainability considerations.
Our Recommendation for Permanent Outdoor Installations
For any permanent outdoor picnic table installation in Australia, parks, schools, councils, hospitality venues, sporting clubs, residential backyards, we recommend Class 1 or Class 2 hardwood over aluminium.
The reasons are practical, not promotional:
- A hardwood table at 20-40 year lifespan costs less per year than an aluminium table at 8-15 years, even accounting for the higher upfront price
- Hardwood is more comfortable in Australian summer sun, thermal conductivity is not a minor factor
- Hardwood can be repaired at the component level (replace a board, re-oil the surface) without specialist equipment or welding
- Hardwood from certified Australian timber suppliers carries a lower long-term environmental footprint when total lifecycle is considered
If your situation specifically requires low weight, we will say so and recommend accordingly. If it does not, hardwood is the better long-term investment for permanent outdoor use.

FAQ
Is aluminium or hardwood better for outdoor tables in Australia?
For permanent outdoor installations, hardwood outperforms aluminium on thermal comfort, lifespan, repairability, and total cost of ownership. Aluminium suits weight-sensitive, temporary, or industrial environments. In Australian summer conditions, hardwood surfaces remain comfortable in direct sun; aluminium can reach 60-70°C under the same conditions.
Do aluminium tables get hot in the Australian sun?
Yes. Aluminium has a thermal conductivity of approximately 205 W/m·K, roughly 1,000 times higher than hardwood. In direct summer sun across most of Australia, aluminium table surfaces can reach temperatures that are uncomfortable or unsafe to touch. Hardwood stays warm but not hot under the same conditions, which is one reason councils and schools consistently specify timber for public outdoor furniture.
How long does a hardwood picnic table last vs aluminium?
Class 1 hardwood picnic tables, Spotted Gum, Ironbark, Merbau, typically last 20 to 40 years outdoors with basic annual oiling, rated under Australian Standard AS 5604 for full outdoor exposure. Aluminium picnic tables generally show meaningful cosmetic degradation (powder coat fading, denting, joint wear) within 8 to 15 years of outdoor use.
What is the cost difference between aluminium and hardwood picnic tables?
Aluminium picnic tables generally have a lower upfront purchase price for standard sizes. However, when total cost of ownership is calculated across a 20-to-40-year service life, including replacement cycles, maintenance, and freight for replacements, Class 1 hardwood typically costs less per year. For permanent installations with a long planning horizon, hardwood is the more cost-effective material. For a written quote on hardwood options, contact our NSW workshop.
