Windows are the most integral part of an architectural project. Apart from providing beauty to the space, windows also improve the house’s energy efficiency by managing the ventilation and natural light entering the room.
Because they have a crucial role in the property’s aesthetic appeal, picking the right window can be tricky. With a wide variety of features, styles, colors, and materials, selecting the best window for your home can be one of the more difficult things to do.
But thanks to fenestration products, manufacturers such as TOSTEM India offer unique colors, designs, and styles that provide complete liberty to the dwellers to choose what they wish for rather than compromising on whatever is available.
What is Aluminium Windows?
Aluminium windows are window frames constructed from aluminium. Aluminium as a metal, is widely famous for being strong and lightweight, making it a popular choice to manufacture window frames. Aluminium frames are typically used in conjunction with glazing (such as double or triple glazing) for enhanced insulation, security, and aesthetic appeal. Aluminium’s ability to offer a high strength-to-weight ratio, allowing for thinner and more durable frames, makes it an ideal material for windows.
What is Steel Windows?
Similar to their aluminium counterparts, steel windows are window frames made from steel. Equally strong and durable as aluminium, steel window frames are widely used in residential, commercial, and industrial buildings. They have been in use for over a century, due to their strength, along with their secure and long-lasting nature. Steel windows are typically manufactured through a process of welding, to ensure that the frame is solid and secure. Particularly valued for their ability to hold large panes of glass, these windows provide a sleek and minimalistic aesthetic.

A Detailed Comparison Between Aluminium and Steel Windows
Some efficient choices in metal framed windows are aluminium windows and steel window frames. However, both have different properties, making them preferable options for various reasons. Let us have a look:
1.
Aluminium vs Steel Windows : Finish
Aluminium can be powder coated or anodized to give it a textured or decorative smooth finish. It means that aluminium windows will perform well and look fantastic. Anodising is also carried out by immersing the aluminium metal into the acid electrolyte bath and introducing an electric current. Aluminium is also believed to increase in strength in colder environments.
On the other hand, steel also has a smooth finish but does not offer exceptional corrosion resistance as compared to aluminium. However, one can consider stainless steel for increased corrosion resistance.
2.
Aluminium vs Steel Windows : Malleability
Frames of Aluminium are made by extrusion and rolling processes where aluminium profiles are joined together. This is achieved because of aluminium’s excellent malleability properties. The nature of aluminium is that it can be moulded into complex designs. These intricate shapes can be easily accomplished with a single extruded section so that the profile does not lose its durability and strength.
Aluminium also has strong machinability, making it easy to accurately fabricate the profiles of aluminium into the modern window design. However, steel is not very flexible and cannot be used for intricate window frame designs including steel window frames.
3.
Aluminium vs Steel Windows : Strength
Alloys of aluminium are used to make windows. It is because pure aluminium does not have its tensile strength. But its strength increases vastly when it is alloyed with other elements such as magnesium, copper, silicon, and manganese. The tensile strength of pure aluminium is around 90 MPs, but it can be increased to 690 MPa as an alloy. While the strength of aluminium increases at cold temperatures, steel becomes brittle at very low temperatures. It means that windows made of aluminium are more durable as compared to steel window frames.
4.
Aluminium vs Steel Windows : Eco-Friendliness
Aluminium is one of the most environment-friendly metals. It is purely recyclable, and the quality of recycled aluminium is the same as virgin aluminium. It means the element can be recycled repeatedly, earning the term ‘green metal’. Steel is also a sustainable choice for having the same nature.
5.
Aluminium vs Steel Windows : Longevity
Aluminium is both ductile and malleable. It can also be pressed or bent into any shape and drawn into a fine wire without losing its toughness. So, you do not have to worry about your aluminium window design cracking or breaking in the longer run. On the other hand, good quality steel can also last for years without any noticeable damage.
6.
Aluminium vs Steel Windows : Corrosion-Resistance
Aluminium windows are the best answer for a low-maintenance window. It is because after coming in contact with air, aluminium forms a protective layer of aluminium oxide which is highly resistant to corrosion and helps prevent oxidation. Due to this, aluminium windows are not too vulnerable to acidic rain, chemicals, and cleaning agents. Also, these frames do not swell, warp, split or crack for many years. By painting or anodizing, you can further protect the frames from corrosion. On the other hand, premium quality steel or stainless steel also has a certain level of corrosion resistance.
The housing products manufacturer, TOSTEM India, offers anodized aluminium windows that provide long-time lustre and surface protection. The anodized coating used by the manufacturer is used for color protection and unmatched gloss retention. The additional protection is offered by the TEXGUARD coating that also resists dust, sunlight, water and heat.
7.
Aluminium vs Steel Windows : Weight
Aluminium is among the lightest engineering metals, with a better strength-to-weight ratio than steel, making Aluminium perfect for window frames. Aluminium, in terms of weight, is about a third of copper or steel. Using lightweight frames is very important when it comes to curtain walling. Moreover, this helps aluminium frames easily hold vast and heavy glass panes so that you can enjoy some stunning views of the surroundings.

Conclusion
Both aluminium and steel windows hold a respectable position in the market, but due to specific properties, aluminium window frames seem to have an edge over steel window frames. Aluminium offers various unique properties which can enhance the house’s aesthetics.
However, one should pick the material that best suits their needs and preferences. Be sure that you carry out thorough research before coming to a decision. We hope that this information helps you do so and pick a material for your fenestration products that cater to all your requirements perfectly.
