Two ranges, one workshop
We make both internal steel doors and internal aluminium doors, so we have no reason to push you towards one or the other. Both are made to measure, both come with a choice of glass and bar designs, and both are templated and installed by our own team across England and Wales. The differences are in the frame, the price, the lead time and one thing only steel can do: fire rating.
| Steel doors | Aluminium doors | |
|---|---|---|
| Frame | Slim welded steel profiles, smooth or textured finish | 26mm opening frame with a 40mm door frame, slimline or fully framed, 40mm deep |
| The look | Industrial black steel look, the finest sightlines | Clean and contemporary, a little more frame on show |
| Opening styles | Hinged, pivot, sliding, folding, fixed panels | Hinged with soft-close hinges that open both ways, double sets, pivot, sliding, fixed partitions |
| Maximum sizes | Pivot doors up to 1350mm x 2000mm; larger openings built as doors with fixed panels | Fully framed leaf up to 930mm x 2200mm; double sets up to 1927mm x 2231mm |
| Fire-rated option | Yes, FD30 certified to BS 476 Part 22 | No. Choose steel where a fire door is required |
| Glass | Clear, frosted, grey tint, bronze tint, wired, fluted, cathedral | Clear, frosted, smoked grey, smoked bronze, reeded, reflex, fabric |
| Colours | Any RAL colour; black is the most popular | Frame colour chosen per order |
| Handles | Hand-welded pull handles with magnetic latch, or lever handles with lock | Pull handle as standard |
| Weight and feel | Heavier and solid, the best noise reduction and security | Lighter, soft close, easy to use every day |
| Single door from | £1,800 (non-fire-rated) | £1,200 |
| Typical lead time | 8–10 weeks (fire-rated 10–14 weeks) | 6–8 weeks |
| Guarantee | 2 years | 2 years |
Choose steel if…
- You want the classic black steel look with the slimmest possible frame.
- You need a fire door. Our FD30 steel doors are certified to BS 476 Part 22 and come with a certificate of conformity for building control.
- You want a lever handle with a lock, or a hand-forged hammered or ridged pull handle.
- The door sits in a busy spot, a hallway or a kitchen, where weight and strength matter.
- You want a pivot door that opens both ways, or a bespoke bar arrangement from our 29 standard designs.
Choose aluminium if…
- Budget is the deciding factor. Single aluminium doors start from £1,200 against £1,800 for steel.
- You want soft-close hinges and a door that swings both ways without a lever handle.
- You are filling a wide opening with a double set, up to 1927mm x 2231mm, and want the lighter leaf.
- You need the doors sooner. Aluminium lead time is typically 6–8 weeks.
- You prefer a clean, contemporary frame over the industrial look, or want reflex or fabric glass.
Common questions
Which is cheaper, steel or aluminium?
Aluminium. A single aluminium door starts from £1,200 and a single steel door from £1,800. Both are made to measure, so the final price depends on size, glass, bar design and handles. Send rough sizes and a photo of the opening for a free quote on either.
Which lets in more light?
Both are glass from top to bottom, so the difference is small. Steel has the slimmer frame, so for the same opening you get slightly more glass. Clear glass keeps the most light in either range; frosted and reeded give privacy while still letting light through.
Can I mix steel and aluminium doors in one home?
Yes. A common choice is a steel door for the statement opening, the kitchen or the hallway, with aluminium doors elsewhere. Tell us which rooms the doors are for and we will advise on keeping colours, glass and bar designs consistent across both.
Are both ranges made to measure and installed by you?
Yes. Every steel and aluminium door is made to your opening. We template on site to confirm the sizes, then return to install, across England and Wales. Supply only is also available for both ranges.
