A metal that has seen a surge in popularity over recent years is that of aluminium. Not only does it provide a whole host of benefits, but it has also become much more competitively priced in the marketplace too. 

For many commercial properties now, aluminium is the first choice when it comes to the installation of windows and doors. 

Aluminium entrance doors especially are vastly becoming the most popular choice for businesses across the UK. In this post, we explore the reasons why this shift in popularity has occurred as well as why you should make aluminium the material for your commercial installation projects.

Aluminium doors – The new norm for commercial buildings

Benefits of Commercial Aluminium Doors 


Aluminium is renowned for being sustainable and extremely durable. It is free from rust and also corrosion resistant due to its protective oxide coating. Making it perfect for entrance doors and windows, providing excellent water resistance, and maintaining its quality even in the harshest of weather conditions, aluminium can be the ideal choice for the best finish to the exterior of your building. 

You also have the option to protect aluminium windows and doors further with a range of coatings. These can be anodised, powder painted, or lacquered.  And can be made available in a variety of colours and with the option of a metallic finish (if you’re looking for the ultimate customisation). 


Aluminium can be fabricated very easily (trust us, at Crucial Engineering; we’re the aluminium fabrication experts!). Melted down and moulded into various shapes and sizes, numerous times, aluminium will never lose its quality. 

Through aluminium fabrication, the material can be moulded and shaped into any specific requirements, allowing you to create some of the most visually impressive building facades out there. 

This level of versatility means aluminium can ultimately be used to create windows, doors, and curtain walling (check out our article on “What is Curtain Walling”).  Due to its incredible strength to support large panes of glass, you also have the option of choosing single, double, or even triple glazing. 


Aluminium is also much more environmentally friendly compared to its metal counterparts, as the material itself is 100% recyclable. 

During the fabrication process, when it is re-melted, it only uses 5% of the energy used in the initial production process. 

Quality is never affected during the re-melting and recycling process, and it can be remoulded several times. 

Reduce your carbon footprint by choosing aluminium frames for your commercial glass doors. 

Energy Efficient

Aluminium can significantly reduce heat transmission, helping you to lower energy bills throughout the building, making it much more cost-effective to run, manage, and maintain. 

Aluminium windows and doors are primarily designed with high levels of insulation, helping to keep warm air in and cold air out. 

For large corporate commercial buildings with glass fronts, aluminium is an excellent choice to help improve overall energy efficiency levels. 


When aluminium windows and doors are installed by professionals (like the professional installation team at Crucial Engineering), you can have complete peace of mind that they will provide high levels of security. 

If your chosen windows and especially glass entrance ways are combined with reinforced glass as well as high tech locking systems, you can achieve much higher levels of security, meeting all security standards and credentials with ease. 

Most commercial properties will be home to secure, valuable equipment and data; with this in mind, you must take all of the appropriate security measures available to help reduce the chance of break-ins. 

Aluminium windows and doors can provide that level of protection and so much more. 

Known as the go-to material of the future, it comes as no surprise that Aluminium is now the first choice for commercial properties and high-rise buildings throughout the UK.
