Choosing Between Aluminium and Steel French Doors: A Guide for Homeowners 

Want the industrial, Crittall®, or Art Deco aesthetic in your home? French doors are a very popular design for patio doors and the most authentic door type in a steel-look. You can design these either as a familiar double door set or a larger combination screen comprising French Doors with side panels.   

Both aluminium and steel French doors promise elegance and sophistication, luxury and quality. Characterised by their multiple panes of glass, divided by thin transoms and their slender surround frames, French doors are a hallmark of timeless design. Aluminium and Steel French doors are the two best steel-look options available.  

The Industrial Look: Authenticity and Aesthetic 

The choice between aluminium and steel French doors usually comes down to four factors.  

  • Authenticity, the original steel vs the aluminium replica. 
  • Whether you prefer the steel or aluminium aesthetic.  
  • Manufacturing and installation times.
  • Matching your French Doors to other windows and doors.  

There is no doubt the industrial style is here to stay, and done right, this edgy, bold and urban style of interior door can remain timeless in most property interiors.

Steel French Doors: The Quintessential Industrial Choice 

Steel French doors are often seen as the gold standard for achieving an authentic industrial look. This is because steel is the original product and aluminium is replicating steel, not the other way round.  Steel has been historically used in residential doors, windows, factory and warehouse windows.  The look of steel, therefore, creates a genuine connection to the true industrial aesthetic.  

Steel French Doors are welded whereas aluminium is mechanically joined like period joinery and craftsmanship. Steel by its nature is a stron metal and can therefore create substantially bigger doors and frames than aluminium. Aluco steel-look French Doors already come at impressive widths and heights, but steel can go even bigger if required.  

The Aluco collection is available in shapes and curves, and we use specialist bending techniques to create a curved head above your new doors or shaped windows.  The nature of steel is such that more complex shapes and curves are easier to achieve such as gothic styles, not usually possible with aluminium.  

Furthermore, steel can be finished with a range of coatings more suited to steel that can’t be done in aluminium such as satin, burnished, blackened and oxidised finishes, again that can’t easily be achieved in aluminium. So, when choosing between aluminium and steel French doors, aluminium is best for standard doors without complex shapes and curves.  Steel is the best in one-off designs and when you must have the tallest and widest doors.

Aluminium French Doors: A Contemporary Take on Tradition 

While aluminium French doors may not have the same historical pedigree as steel, they offer a compelling contemporary interpretation of the industrial style. Aluminium can be fashioned to mimic the thin sightlines of steel, providing a similar aesthetic with the added benefit of being lightweight. Advances in manufacturing mean that aluminium doors can be designed with intricate details, echoing the elegance of traditional steel designs. 

Aluminium frames can be powder-coated in a variety of finishes, including the ever-popular matte black. This versatility allows homeowners to achieve a look that closely resembles steel while potentially offering a wider range of customisation options.

There are two main advantages of aluminium French Doors in the steel or industrial style.  

  •  An aluminium door set is typically around one third the cost of a comparable steel product.
  • Aluminium doors are typically manufactured in around 4-6 weeks.  Steel doors typically take up to 20 weeks to manufacture.

Choosing Aluminium vs Steel French Doors. Make Aluco the right choice for your home.

But the manufacturing times are lengthy and they come at the highest prices.  

On the other hand, the Aluco Exterior Collection of aluminium doors provide a modern take on this classic style, with competitive sightlines and greater design flexibility.  With other brands of aluminium steel look doors, you won’t replicate the styling and sightlines of steel.

We did some research and came to Luxe Interior doors by Aluco.The double doors from our kitchen to hallway look stunning, they look and feel like the quality doors that they are. Thank you Kieran.
Exceptional products, high end finish.The team at Aluco are fantastic, always helpful, quick to respond & offer support from quoting through to install.
Brilliant customer service from Kieran, very helpful and went out his way to provide us with a replacement part that was damaged during installation. Very satisfied with the quality and design of the doors we purchased
We wanted to invest on a quality set of doors as one of the main focal points in a rather large extension of our home. After doing some research we settled on Aluco. Our contact from start to finish was Kieran, who was so helpful, constructive and knowledgeable. When installed we were so pleased as the fit was perfect, the finish outstanding. Not only did we consider the quality better than other options we looked at, the cost was nowhere near them. So much that our window/door fitters that we used on the job are now looking at them as an alternative. A solid 5 out of 5 and would definitely use again.
Great quality aluminium internal doors and quick professional service. Very happy with the products and buying experience. Kieran is super helpful!
After having a horrible experience with another company, we got in touch with Aluco and they couldn’t have been more helpful. As we are doing a self build, they helped us pick the right doors for the look we were after and to make the best use of our available space. We knew the doors and windows are a top quality product and couldn’t be more pleased with them when they arrived. Everyone we spoke to went out of their way to help and we felt they took a personal interest in resolving our predicament, so it’s a five star review from us for both the service and product.
Response from the owner: Thank you so much for the review,it was a pleasure working with you guys..and we are over the moon you guys are happy with the Aluco steel look doors..Kind Regards Aluco Team.

Can’t fault the finished product once installed - they really give the space the ‘wow factor’.
Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.
So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!
