Aluco steel look interior doors deliver the best possible solution whether you choose a single or double door set with or without fixed glazed panels. Only Aluco interior doors give you the slimmest possible frames and glazing bars inspired by original steel doors. Opening in or out, Aluco doors have no visible threshold, with 10mm floor clearance and are designed to work in any room. A refined elegance in any room, office or commercial property whilst always delivering on form and function.

Aluco – the closet to steel doors

Single doors are perfect for any existing doorway, such as a utility room, bathroom, study, or smaller doorway. Closed, they deliver the privacy you need, and open, they connect your rooms together whilst always stylish and distinctive. Double doors create an even more impressive door design with impact, redefining a kitchen leading to a dining area or separating a lounge. Combine our single or double doors with a screening system, and these transform into stylish room dividers. Even better, you can create a corner or angled configuration in a larger space, creating a room within a room.

Only with Aluco: Unique Steel Look Door Features You Can’t Find Elsewhere

Now completely redesigned and even more advanced, Aluco steel-look interior doors are the slimmest you can buy, and you get even closer to steel doors in appearance. Entirely made around the glass, these outstanding doors are thinner yet stronger than others. With a reassuring feel and the perfect weight and rigidity, the unique wrap-around sash ensures maximum sound reduction and no clean lines throughout. Closed, the overlapping frame design looks sleeker and neater, providing even better sealing and acoustics. The ingenious centralised glazing design makes Aluco unique, with perfect and identical sightlines and appearance on both sides of the door set. Balanced styling, true symmetry and, above all, beautiful to look at and use daily. These are just some of the many unique and exclusive design and product features of Aluco steel-look interior doors.

Designed for virtually any size doorway, Aluco doors have a mere 47mm frame and sash sightline, the smallest meeting mullions on double doors, the slimmest feature lock body and the most steel-like 20mm glazing bars. Door sizes go up to an impressive 1000mm wide and up to 2500mm high. Double doors up to 1900mm wide and 2500mm high, or any size in between. Adding glazed panels above or to the sides enables the creation of even larger screens in virtually any design and even wider and taller sizes.

Aluco steel look interior doors are fully bespoke, giving a choice of sizes, colours, glass designs, and ultra-slim or standard glazing bars. Finishing off the doors perfectly is an architectural quality range of handles and door accessories. Lock options are cleverly designed for use in any room, including a latch only, latch and cylinder and bathroom locks.

The incredible floating lock design option is unique to Aluco interior doors, giving the look of the door handle suspended in the glass. We created this stunning door style for when you prefer a fully glazed door without losing the look of the authentic backplate behind the lever handles that are so desirable. A feat of engineering and know-how, the floating lock design also gives you the thinnest possible fully glazed doors. Find out more about the features and benefits you only get with Aluco steel look internal doors.

Every one of our hand-made Aluco steel look interior doors comes with the finest quality aluminium profiles, protected by a gorgeous marine-grade colour finish, first-class manufacturing and supported with a comprehensive manufacturer guarantee. Whichever bespoke door we create, each promises something truly special for your space from one of the original designers and creators of steel-look, heritage and industrial-styled doors. Only we make our products, and our carefully selected, fully trained and approved Aluco Distributors professionally install them. Aluco interior doors – maximum impact and enjoyment in any room.

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!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
