Can Aluminium Withstand Weather Conditions?

If you are planning a garden for next season and considering purchasing aluminium garden furniture, one question commonly raised is:

Does aluminium corrode in rain and snow conditions?

Aluminium does not corrode like steel or iron, which makes it an ideal material for planes, cars, boats, outdoor furniture and marine components. Even in wet, cold and harsh weather it performs extremely well, although it still needs occasional maintenance to keep it looking its best. This guide explains how to choose aluminium furniture that lasts.

This guide explores why aluminium does not rust, how it reacts in wet and snowy environments, potential sources of corrosion over time and ways to extend its longevity in UK gardens for 15 years or more.

Why Aluminium Does Not Rust in Rain and Snow

Aluminium stands out among metals for its unique behaviour. While iron and steel rust and decay when exposed to rainwater, aluminium forms a thin protective layer through oxidation. This layer protects the metal instead of damaging it.

Oxidation vs Rust

Steel or Iron: Oxidation forms rust which weakens the metal.

Aluminium: Oxidation forms a protective layer that strengthens resistance to water and snow.

Does Aluminium Corrode Instead of Rusting?

Aluminium does not rust, although it may corrode in certain conditions such as long term exposure to moisture, salt air, pollution or harsh chemicals..

Corrosion is usually superficial. The frame remains strong even if you notice the following:

• Small white spots or chalky residue on the surface.
• Colour fading if the coating is poor quality.

Quality powder coated aluminium used in premium garden furniture can resist corrosion and maintain its colour for up to 20 years.

How Aluminium Reacts to Rain

Aluminium performs well in wet environments when properly powder coated. However, dirt, cold temperatures and standing water can reduce its appearance over time.

Heavy rain can cause:

• Water stains.
• Mould on cushions, though not on aluminium frames.
• Fading of low quality painted finishes.

But with two simple steps, rain becomes easy to manage:

1. Clean the furniture every few weeks.
2. Use a breathable cover during long periods of rain.

How Aluminium Handles Snow and Frost

Aluminium garden furniture performs well in cold conditions and lasts longer in snow compared to plastic, untreated wood or rope furniture. However, prolonged snowfall can trap moisture on the surface which may slowly affect the coating.

Snow and frost may cause:

• Chalky residue when snow melts.
• Light surface corrosion spots.
• Frozen cushions if left outdoors.

Powder Coated Aluminium Is Important

Premium outdoor furniture often uses powder coated aluminium because it is far more durable than painted metal or cheaper alloys.

Benefits include:

• Protection against fading caused by sunlight.
• Better resistance to moisture in rain and snow.
• Easy maintenance using warm water and mild soap.
• Long lifespan of up to 25 years.

Cleaning Aluminium Furniture After Rain or Snow

Cleaning aluminium furniture is simple. Follow these steps:

1. Mix warm water with mild soap.
2. Use a soft cloth only.
3. Rinse thoroughly with clean water.
4. Dry naturally in fresh air.

Steps for Protecting Aluminium Furniture During Rain and Snow

• Use a breathable outdoor cover.
• Store cushions indoors.
• Steam clean before winter if possible.
• Check for loose screws.
• Elevate slightly to avoid direct contact with wet ground.

Avoid airtight plastic covers because they trap moisture and may damage the coating.
