Aluminium Vs Steel Windows: A Comprehensive Comparison Of Key Features
August 23, 2023
The windows of a home not only provide an aesthetically pleasing view of the outside world but also protect against the elements. Therefore, it is essential to make the right choice of material when selecting windows for a home. Aluminium and steel are two of the most popular window materials, but how do they compare? In this blog, we will take an in-depth look into the key features of aluminium vs steel windows, such as finish, malleability, strength, eco-friendliness, longevity, and corrosion-resistance. By the end of this blog, you will know which material is the best choice for your home.
Comparing Aluminum and Steel Windows: Finishing
When it comes to window frames, there is a large range of finishes available for both steel and aluminium
windows. Aluminium window frame usually come in powder-coated finishes, which are known for their durability and resistance to fading. Steel window frame, are often galvanised and can be painted, giving them a sleek and modern look. Both materials offer a range of advantages and disadvantages when it comes to their finishes. Aluminium frames are known for their low maintenance requirements and long-lasting, fade-resistant finish, while steel frames are more durable and cost-effective in the long run.
Malleability of Aluminium vs Steel Windows
For malleability, aluminium is the clear winner. Aluminium is much easier to bend and shape than steel, which makes it ideal for custom window designs. Aluminium can be rolled, pressed, and forged into intricate shapes, allowing window frames to be designed in any shape or size. The malleability of aluminium also means that it is more lightweight than steel, making it easier to install and less cumbersome. However, the malleability of aluminium is also its downside, as it is more prone to dents and scratches than steel. The malleability of Aluminium framed windows and steel framed windows also depends on the type of material used. Steel windows are generally more malleable when made using stainless steel, while aluminium windows are more malleable when made using an alloy.
Strength Comparison: Aluminium vs Steel Windows
The strength of the material used to make windows
has a significant impact on its long-term performance. Aluminium is one of the strongest and most durable materials used in modern window frames. It offers excellent strength and rigidity, while also being light in weight. Steel is also a powerful material that provides exceptional durability. Although heavier than aluminium, steel is more resistant to extreme weather and is a better choice in areas prone to high wind and heavy rain. Both materials can support large windows without sagging or bending. However, aluminium is often considered the better option, as it provides superior strength and stability while being lighter.
Which is More Eco-Friendly - Aluminium or Steel Windows?
When it comes to the environment, both aluminium and steel windows have a lot to offer. Aluminium is a relatively “green” material, as it is 100% recyclable and requires less energy to produce than steel. Aluminium is a non-toxic material and contains no volatile organic compounds (VOCs). Steel is made from molten iron ore that has been extracted from the earth, a process that requires large amounts of energy. However, steel windows can be recycled and re-used, often for multiple lifecycles. In the manufacturing process, both aluminium window, and steel windows are manufactured in an energy-efficient manner. Aluminium manufacturing plants are designed to be highly efficient and often use recycled aluminium for production. Steel manufacturing plants also use recycled materials and have reduced their carbon footprint through the use of renewable energy sources. For eco-friendliness, aluminum and steel windows are viable options.

Longevity of Aluminum vs Steel Windows
In longevity, both aluminium and steel windows can last for many years if properly maintained. Steel windows typically last longer than aluminium windows, with some studies suggesting that steel windows can last up to four times as long as aluminium windows. However, aluminium windows can last up to 20 years and beyond with proper care and maintenance, making them a viable option for homeowners looking for long-lasting windows. The longevity of both window materials is influenced by several factors, such as exposure to the elements and regular cleaning. Steel windows are more resistant to corrosion than aluminium windows, making them more durable and less to suffer from premature deterioration. Aluminium windows are also susceptible to environmental factors, such as temperature changes and moisture, which can reduce their lifespan. The cost of the materials and installation are also important factors to consider, as steel windows require more of an upfront financial investment, while aluminium windows are more affordable and cost-effective.
Comparing Corrosion-Resistance of Aluminium and Steel Windows
When it comes to corrosion-resistance, there is a distinction between aluminium and steel windows. Aluminium windows are inherently resistant to corrosion and remain in good condition for longer than steel windows. This is because aluminium has a strong protective oxide layer that helps protect it from the elements. Steel is prone to rusting and corrosion. Factors such as the type of coating used, the environment, and maintenance will all impact the corrosion-resistance of the window. However, for longevity and cost, aluminium window designs is the clear winner as it requires less maintenance and has a longer lifespan than steel window design because of its superior corrosion-resistance.
