01

How it’s built

Steel frame, welded leaf, toughened glass. Powder-coated as one assembly. Frame, leaf, hinges and hardware all finish the same colour.
02

Where it works best

Any room, any opening up to 1,100mm wide. Beyond that, a double or pivot works better. Repeats well across apartment buildings and commercial fitouts.
03

How to order it right

Confirm size and swing direction first. Choose glazing: full-light, half-light or solid panel. Pick finish and hardware. Fire rating and thermal break available. Lead time 8 to 10 weeks.

The details, answered

Your questions
Clear answers

What is the maximum width for a single steel door?
Around 1,100mm. Beyond that the weight makes it uncomfortable to use, and a double or pivot is usually the better answer. If you have a specific wide opening, talk to us before assuming it needs a double.
How long does manufacture take?
8 to 10 weeks from drawing sign-off. Fire rating or bespoke hardware can add two to three weeks. We confirm the programme at the time of order.
Can I have a cat or dog flap?
Yes. We incorporate the aperture into a solid panel below a glazing bar. The flap itself is supplied by a specialist, and we design the panel around the dimensions you give us.
Are your doors thermally broken?
Internal doors are not thermally broken as standard. External doors and doors to unheated spaces are available with a full thermal break and weather sealing. Specify this at the time of order.
Can a single steel door be fire-rated?
Yes. FD30 and FD60 are both available in the same slim-sightline profile, with third-party certification. They can be specified with the same glass and finish options as our standard doors, subject to the glazing restrictions that fire rating imposes.
What glass options are available?
Clear, ultra-clear, reeded, fluted, frosted, smoked, tinted, acoustic-rated and fire-rated. Double-glazed units are available for external doors or where acoustic performance is a priority.
Can you match an existing finish?
Yes. Give us a RAL or BS colour reference or send a physical sample. We powder-coat the complete assembled unit, so the frame, leaf and hinges finish consistently. We always send a powder-coat sample for approval before production starts.
Do you supply and fit, or supply only?
Both. We are based in London and install across the UK. We also supply-only to your contractor anywhere in the UK, and we deliver to European countries. Full fitting instructions and technical support are included with every supply-only order.
Can the swing direction be changed after manufacture?
No. Swing direction is fixed at the drawing stage and built into the frame. We confirm this carefully at the start of every project before production begins.
What warranty do you offer?
Ten years on frames and glazing, five years on hardware. Powder-coat is ten years internal and five years external, subject to normal maintenance. Full warranty terms are provided with every order.
