Create the look of traditional steel, Crittall-style or Art Deco doors with modern thermally improved aluminium. Newlite supplies and installs steel-look and heritage aluminium doors across Sussex, Kent and Surrey, including French doors, patio doors, front doors, internal doors and glazed screens.
Our doors are designed for homeowners who want slim frames, elegant glazing bars and a premium heritage appearance without moving to genuine steel. Every set is made to order around the opening, the property style and the way you want to use the space.


Very personable professional service with the excellent fitter Martin who also fitted the cat flap and he also adjusted the patio door (where there was an existing gap), without us asking, and realigned the gap.
Great local service.

Martin, Tony and David fitted our windows and were lovely throughout, they kept us updated on the progress throughout the installation.
After taking a while to decide, we chose slimline uPVC windows with white interiors and anthracite grey exteriors, and we absolutely love how they look. They’ve transformed our house!
We are looking forward to getting our bi-fold doors fitted next. Thank you to Alan and everyone at Newlite. We would highly recommend them 🙂

From the start of the process, having the survey done to the final installation, the customer service has been excellent.
They are prompt at replying to all queries and nothing is too much trouble.
The installation team were curtious and polite. They cleaned up after themselves and left my house after the installation as clean as they found it.
The product is good quality, a 1st class service all in all 10 out of 10.

The quality and look of the windows is just what we hoped for and the team have been quick to respond to minor issues that I'm sure are typical soon after installation.

I needed to find a local company who I could trust to complete the last stage of a staggered window replacement, having been very dissapointed by the previous installer.
It quickly became apparent to me that we were in very good hands indeed with Newlite. The whole process was very well managed by Alan and his team . Here is a company with a no nonsense approach combined with good values and an obvious care to the project in hand. Thank you for a job well done.

Steel-look aluminium doors for inside and outside the home
Steel-look aluminium doors work beautifully as external doors to a garden, terrace, porch or extension. They are also a strong choice inside the home where you want to divide rooms without losing borrowed light. The same visual language can be used across doors, side panels, top lights, internal screens and matching windows.
French doors
Heritage aluminium French doors with slim glazing bars, side panels and optional deep bottom rails for a traditional steel-inspired appearance.
Patio and sliding doors
Steel-look patio doors and slim sliding doors for larger openings where you want the industrial style with easy garden access.
Internal doors
Internal steel-look doors and screens for home offices, kitchens, dining rooms, hallways and New York-style room dividers.
Crittall-style and Art Deco door designs
Crittall-style is often the phrase people use when describing this look. Newlite supplies aluminium alternatives inspired by classic steel doors, with crisp bars, balanced sightlines and a choice of black, white, grey or other powder-coated finishes. The result suits Art Deco homes, Victorian and Edwardian properties, contemporary extensions and period-style renovations.
We can help with glazing bar layouts, door proportions, lock plates, threshold choices, handles, side panels and top lights so the finished door set looks intentional rather than simply customised.
External steel-look doors
For external use, our steel-look aluminium doors combine heritage styling with modern weather performance. Doors are fitted with quality seals, secure locking, safety glass and durable powder-coated aluminium frames. They can be designed to open in or out depending on the property and the project.
- Single and double doors.
- French doors with side lights and top lights.
- Steel-look front porch doors.
- Patio doors and garden doors.
- Matching heritage windows and fixed glazing.
Internal steel-look doors and screens
Inside the home, steel-look aluminium doors are used to define spaces while keeping light moving between rooms. They work well between kitchens and living areas, in hallways, home offices, dining rooms, conservatories and open-plan spaces. For sliding internal doors, Newlite also offers AluSpace internal sliding doors.
Security, performance and thresholds
Modern aluminium steel-look doors are not just about appearance. External doors use insulated aluminium profiles, secure locking and high-performance glass. We can also advise on standard thresholds, lower thresholds and internal zero-threshold designs where accessibility and a clean floor finish are important.
Door details and options
- Black, white, grey and specialist RAL colours.
- Horizontal and vertical glazing bars.
- Side panels, top panels and matching fixed glazing.
- Period-style handles, lock plates and hardware finishes.
- Toughened, laminated, obscure, reeded and acoustic glass options where suitable.

Steel-look aluminium doors FAQs
Can steel-look doors be used as front doors?
Yes. Steel-look aluminium can be used for front doors and porch doors where the design suits the property. We can include side panels, top lights and secure locking for external use.
Are these genuine Crittall doors?
No, unless stated otherwise. Newlite supplies aluminium Crittall-style alternatives that recreate the visual character of classic steel doors using modern aluminium systems.
Can internal doors have no threshold?
Often, yes. Internal door and screen designs can be specified with very low or no visible threshold depending on the system and installation detail.
Can doors match steel-look windows?
Yes. We can design matching doors, windows, fixed panels and internal screens for a consistent heritage or Art Deco style.
