Steel Look Internal Doors and Screens

Steel Look internal doors and screens create a stylish interior inside the home, complementing the exterior steel look windows and doors . Minimalist, slimline and distinctive, there’s a range of Crittall style internal doors and aluminium steel look internal screens. Everything you need to know about steel-look internal doors and screens and aluminium Crittall style room dividers.

Steel look internal doors and screens explained

Only genuine steel products such as Crittall® Windows, or other steel brands provide the best sightlines and true steel look. The aluminium versions of Crittall style room dividers or doors take inspiration from steel.

Steel always provides slimmer lines, but aluminium comes close. As well as this, other distinctive styling hues from the original products include the grid-like appearance, consistent lines, optional deep bottom rails and the thicker plate or panel behind any handles.

It’s also worth knowing many of the products in aluminium markets as interior system are actually external-grade products. Only Aluco Aluminium provides a dedicated interior system. It’s different from steel but highly effective.

If you’re choosing exterior systems it’s likely you’ll get double glazing and thermally insulated profiles – two elements you don’t need inside but perfectly acceptable nonetheless.

You’ll also find the same sightlines with the exterior-use models but there’s some excellent customisation available from specialists giving the right functionality, look and feel.

It’s also worth remembering with the exterior systems that you’ll quite likely get the same locks used on exterior doors such as multi-point locks. Again it’s not required as many internal doors only have a basic latching system, but many customers are happy with this arrangement.

Fire-rated steel look internal doors and windows explained

steel look internal doors and screens in an apartment

With many interior doors and screens having a requirement for fire-resistance, how do these products stack up?

Aluminium has no fire rating. Therefore, if planning or building design calls for a fire-rated or resistant product, these are not suitable in standard aluminium product. Some think simply glazing with a fire-resistant glass is enough. It’s not and not recommended.

Fire-rated interior doors, regardless of material are specialist products. They undergo testing, certification and their core function is safety over looks. Therefore, if your property has a requirement for fire-rated doors and you want the steel look, only certified products from specialist installers are suitable. You can find out more about this style of glazing, also has fire protection.

The choices are either steel with a fire-rating or steel-clad aluminium, also having the appropriate certification. Always seek professional advice. Schuco Jansen and other suitable systems do come with fire protection and in the steel-look. IQ Glass is one good business also offering these protective screens in a frameless and the Mondrian product. Of course, Crittall® makes Innervision FR and Crittall®Fireline. Clement Windows and other independent businesses also have their own tested fire-rated products.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
