A staircase is the one piece of metalwork people touch every day.

It carries weight, takes wear, holds a sightline, and — in the case of a feature stair inside a heritage conversion — sets the tone for the whole room. Get the structure wrong and the consequences range from a wobble underfoot to a Building Control rejection. Get the design wrong and you've spent four to eight weeks of fabrication time on something that doesn't sit right with the building. Get the welds wrong and there's nothing cosmetic about the problem.

This is exactly the work coded welding exists for. Our fabricators are certified to BS EN ISO 9606 for fusion welding — the same standard used on pressure vessels and structural members — and every staircase that leaves our Leeds workshop is welded by them, not by anyone else. We don't subcontract the welds and we don't ship in pre-assembled flights from a catalogue. The stair you specify is the stair we build, in the dimensions your architect or building designer signs off.

A homeowner reworking a stone-walled barn conversion, a developer roughing in mezzanine access to a new warehouse, a commercial landlord adding an external fire-escape route — the principle's the same. Bespoke staircases Leeds property owners can put weight on, finished to last, designed to the standards they need to clear.

What We Build

Every staircase is fabricated to specification in our Leeds workshop. We work primarily with mild steel and stainless steel, with treads, stringers and balustrade integration tailored to the application. Standard configurations are available as starting points; every quote is sized, shaped and detailed for your specific opening, span and storey height.

Bespoke feature staircases (residential)

Floating designs, helical forms, curved flights, and sculptural feature stairs that become the centrepiece of a heritage conversion or a contemporary build. Stringers can run as a central spine for the clean floating look, or as twin side stringers for a more traditional silhouette. Treads in steel, timber, stone or glass — whatever matches the architectural intent. These projects start with your architect's drawings and progress through CAD detailing before a single section is cut.

Industrial access stairs (commercial)

Internal and external access staircases for warehouses, factories, distribution centres, plant rooms and multi-storey commercial premises. Galvanised mild-steel construction is the standard specification — corrosion-resistant for external runs, abrasion-resistant for high-traffic interiors. Open-mesh or chequer-plate treads provide drainage and slip resistance. Integrated handrails, kick-plates and intermediate landings detailed in. For warehouse builds, we routinely supply these alongside our steel mezzanine floors so the access stairs land cleanly at the new level.

Spiral staircases

Space-efficient stairs built around a central column — popular for mezzanine access, loft conversions, and as architectural features in tight footprints. Available in standard and bespoke diameters with steel, timber or chequer-plate treads. Where a spiral staircase serves as a primary means of escape rather than secondary access, Building Regulations Part K places minimum-diameter and tread-geometry constraints — your architect or building designer specifies these and we manufacture to those drawings.

External fire-escape stairs

Galvanised external staircases designed to support a building's means of escape strategy under Building Regulations Approved Document B. These overlap heavily with our wider external fire escape stair work; where you need a standalone escape route, that's the page to read. Where the requirement is a mixed-use access stair that doubles as an escape, we detail the geometry, handrail, landing platform and protective coating to the specification your architect or building designer provides.

Mezzanine access stairs

Connecting stairs between ground level and a new mezzanine floor — typically half-flight or single straight runs with intermediate landings. Treads in chequer plate or galvanised open mesh; balustrade and handrail integration to BS 6180. Where the same project requires stairwell balustrades at the new upper landing, we fabricate stair and balustrade together so the joinery details match.

Treads, stringers, balustrade integration & finishes

Tread options run from steel chequer plate and galvanised open-mesh grating (commercial/industrial) through to timber, stone and toughened glass (residential feature stairs). Stringers can be central monostring for the floating look, or twin side stringers for traditional flights. Risers are open or closed depending on the design brief and the location's Building Regs context. Handrails and balustrades are designed and fabricated as part of the same package — we don't bolt on a third-party balustrade to a staircase we made.

Standard finishes are hot-dip galvanising for external and industrial runs, powder coating in any RAL colour for interior visible work, and stainless brushed or polished for contemporary residential. Anti-slip nosings are available on every tread spec.

Standards we work to: Designed in line with BS 5395 staircase requirements; subject to Building Control approval. Welded by coded operatives certified to BS EN ISO 9606. Fabrication tested to BS 4872. Stair balustrades fabricated in accordance with BS 6180.

A note on structural design. All metalwork is fabricated to the specifications provided by the client's structural engineer or architect. Final compliance with Building Regulations is subject to the overall building design and is confirmed through Building Control approval. For projects requiring primary structural elements, we work alongside your structural engineer or architect — they sign off the structure, we manufacture and install the steel.

How We Build a Staircase

Brief & drawings

Send your architect's drawings, a sketch, or photos of the opening and storey height. Reference images of designs you like are welcome.

Site survey

We measure on site — floor-to-floor height, opening width, landing positions, structural fixings. Free and no obligation.

CAD & quote

Detailed CAD drawings showing going, rise, headroom, balustrade integration. Written, itemised quote typically inside three working days.

Fabrication

Built in our Leeds workshop by coded welders. Lead time is typically four to eight weeks depending on complexity; we send photos at key stages.

Finish & install

Galvanised, powder-coated or painted to spec, then fitted by the same team that built it. Handed over working — handrail aligned, treads bedded in.

Why Colemans Steel for Staircases

01

Coded welding on every weld

Our fabricators are certified to BS EN ISO 9606. Stair joints carry weight every day for decades. Welding tickets are available on request — we share them.

02

Built to BS 5395

Stair geometry detailed in line with BS 5395 staircase requirements. We don't argue going and rise with your Building Control officer — we design to the standard upfront.

03

Stair + balustrade as one package

The handrail and balustrade aren't bolted on at the end by someone else. We fabricate them with the staircase so the detailing aligns.

04

Architect drawings welcome

Send us your architect's GA. We'll detail it in-house, fabricate to it, and install. No designs lost in translation between three parties.

Where We Install Staircases

Rooted in West Yorkshire, working nationally. Our workshop is in Leeds. We install residential feature staircases routinely across Leeds and the wider Yorkshire region; for larger commercial access-stair packages, mezzanine builds and external fire-escape stairs we deliver and install UK-wide.

Frequently Asked Questions

Do you design staircases to Building Regulations Part K?

We fabricate to your architect's or building designer's specification, and that specification should already comply with Building Regulations Part K (Protection from falling, collision and impact). Part K controls going, rise, headroom, handrail heights and pitch — typically the architect signs these off, we manufacture to the dimensions, and your Building Control officer confirms compliance on inspection. If you don't yet have an architect, we can recommend one local to West Yorkshire.

What does BS 5395 cover, and why does it matter for my staircase?

BS 5395 is the British Standard code of practice for the design of stairs — including straight flights, helical stairs and spiral stairs. It sets out recommendations for stair geometry, tread dimensions, headroom and handrails that complement the Building Regulations. We design and fabricate in line with BS 5395 so the stair coming out of our workshop is geometrically right for your building. Final compliance is confirmed through Building Control.

What is the design process — do I need to bring drawings?

If you have architect's drawings, send them. If you don't, send photos of the opening, the floor-to-floor measurement, and any reference images of designs you like. We carry out a free site survey, produce detailed CAD drawings showing going, rise, headroom, tread layout and balustrade integration, and issue a written quote — typically inside three working days of the survey.

How long does a bespoke staircase take to make?

Typically four to eight weeks from design approval to installation, subject to project complexity and current workshop workload. Feature staircases with curved or helical geometry are at the longer end; straight industrial access stairs are at the shorter end. We confirm a target install date at the point of quotation and send progress photos at key fabrication stages.

What materials and finishes can you use?

The structural frame is mild steel or stainless steel. Treads can be steel (chequer plate or open mesh), timber, stone, toughened glass, or concrete-filled pans — whatever the architect specifies and the application requires. Standard finishes are hot-dip galvanising (external, industrial), powder coating in any RAL colour (interior, visible), and brushed or polished stainless. Anti-slip nosings are standard on commercial and industrial treads.

Can a spiral or helical staircase be used as a main staircase?

Yes, provided it meets Building Regulations Part K and BS 5395 Part 2 (which covers helical and spiral stairs specifically). Minimum diameter, tread geometry and headroom requirements are stricter for primary stairs than for secondary access. Your architect or building designer specifies these on the GA, and we manufacture to those dimensions. As a general guide, primary spiral stairs typically need a larger diameter than purely-decorative or loft-access spirals.

How do floating stairs and traditional stairs differ structurally?

Traditional flights run on two side stringers carrying the treads between them. Floating stairs hide most of the structure — typically using a single central spine stringer with treads projecting either side, or wall-fixed treads with a structural support hidden in the wall. Floating designs put more load through fewer connections, so the structural detailing has to be right. Both routes are viable; we'll recommend the right approach for your span, storey height and architectural intent.

How is the balustrade integrated with the staircase?

As part of the same fabrication package, not as a bolt-on afterthought. We design and build the stringers, treads, handrails and balustrade together so the fixing positions, post centres and rail terminations align. Stair balustrades are fabricated in accordance with BS 6180. Glass balustrades, vertical-bar balustrades and traditional ornamental balustrades are all available. For projects that need a separate landing balustrade away from the staircase itself, see our stairwell balustrades page.

Do you make fire-rated staircases?

Where a staircase serves as a means of escape, the steelwork needs to support the building's overall fire strategy under Building Regulations Approved Document B. We manufacture and install in accordance with Approved Document B and the specific fire-resistance specification your fire engineer or architect provides. For dedicated external escape staircases, see our external fire escape stairs page — that's the full service in detail.

How much does a bespoke steel staircase cost?

It depends entirely on the type, span, tread material, finish and balustrade specification. A galvanised industrial access stair with chequer-plate treads is the most economical end. A feature floating staircase in stone with stainless balustrade is at the upper end. All quotes are written, itemised and subject to specification and site survey — we don't quote off a guess down the phone.
