Zincalume vs Colorbond Sheds: What’s the Big Difference?

If you're in the market for a durable, no-fuss garden shed or workshop, Zincalume Steel is a material worth considering. Whether you need a secure storage solution or a sturdy workspace, sheds made from Zincalume offer a long-lasting, cost-effective option that stands up to the harsh Australian climate.

But what makes Zincalume Steel such a popular choice among property owners? And how does it compare to Colorbond Steel? Let’s take a closer look at the difference between Zincalume vs Colorbond, including key factors like price, durability, and maintenance.

What is Zincalume Steel?

Zincalume Steel is a very durable steel product developed by BlueScope Steel, the specialist steel manufacturers in Australia. Unlike traditional galvanised steel, Zincalume features a special coating system composed of aluminium, zinc, and silicon, enhancing its corrosion resistance and improving its overall durability.

This innovative manufacturing process makes Zincalume steel an extremely durable option for sheds, garages, industrial buildings, and other outdoor structures. 

What is Colorbond Steel? 

Colorbond Steel is another product developed by BlueScope Steel. It is designed for those who want aesthetic variety alongside durability, with 5 colours to choose from. It is made by applying a pre-painted finish to Zincalume Steel, which enhances its visual appeal and provides additional resistance against corrosion and weather conditions.

While Colorbond Steel offers a range of colours, this added feature can be more expensive. 

Zincalume vs Colorbond Steel: Key differences

There are a few critical factors to consider when choosing between Zincalume and Colorbond Steel. Let’s dive in. 

Durability & corrosion resistance

Zincalume Steel is designed to withstand corrosion far better than traditional galvanised steel. Its aluminium-zinc alloy coating ensures it lasts four times longer than standard steel, even in harsh weather conditions.

While Colorbond Steel adds a painted layer, Zincalume’s superior core composition provides the same level of longevity without requiring a pricey colour coating.

Low maintenance—no extra coatings needed

With Zincalume, you don’t have to worry about repainting or resealing your shed over the years. Unlike Colorbond Steel, which may require touch-ups or replacements if the painted layer is damaged, Zincalume maintains its original integrity without additional treatments. Simply hose it down periodically and remove any debris from the roof to keep it looking great.

Best value for money—Zincalume vs Colorbond prices

Cost is a major factor when choosing a shed, and Zincalume Steel is a winner in terms of affordability. Zincalume is cheaper to manufacture, purchase, and install than Colorbond without the added cost of a custom colour coating.

For property owners who value function and durability, Zincalume sheds deliver exceptional durability at a fraction of the cost of Colorbond sheds.

Sustainable & thermally efficient

Colorbond and Zincalume are made from 100% recyclable materials, making them eco-friendly. However, Zincalume has superior thermal efficiency benefits, reflecting more heat and keeping your shed cooler in hot conditions. This is an excellent material option for an energy-efficient outdoor workspace and storage unit.

Common questions about Colorbond vs Zincalume 

Does Zincalume rust? 

No, Zincalume steel is specifically designed to resist corrosion. Its aluminium-zinc alloy coating prevents rust from forming, even in harsh weather conditions.

Is Zincalume suitable for coastal areas?

While Zincalume Steel is highly corrosion-resistant, it may not be the best option for coastal areas where it is constantly exposed to salt-laden air. In these conditions, Colorbond Steel may be the right material for long-term protection.

Do I need to paint Zincalume?

No, Zincalume Steel does not require painting or additional coatings. Unlike Colorbond Steel, which has a pre-painted finish, Zincalume maintains its protective properties naturally, making it a low-maintenance choice.

Is Zincalume Steel suitable for bushfire-prone areas?

Yes, Zincalume Steel meets Australian Standards for use in bushfire-prone areas. Its non-combustible properties make it an excellent choice for regions where fire resistance is a priority.

How do Zincalume sheds hold up in extreme weather conditions? 

Zincalume sheds are incredibly durable against Australia’s extreme weather conditions, and most of our sheds are approved for Australian Standards AS11790.2.02 non-cyclonic conditions (N2). However, in high-wind or cyclone conditions, we recommend investing in one of our cyclone kits to add extra support to the Zincalume core. This will upgrade your shed to wind classification C1.

Is Zincalume Steel environmentally friendly?

Yes! Zincalume Steel is 100% recyclable, making it a sustainable choice for Aussie property owners. Its reflective properties also enhance energy efficiency, helping to keep sheds cooler in hot climates.
