No obligation. 5★ Verified reviews on stairs Building Regs Rise, going & handrails Skilled Trade experience Free Site survey & quote 01 — Overview ## What steel staircases & external stairs actually is — and when to commission it. ### What it is Steel staircases are made from a welded steel frame — stringers, treads, risers and landings — finished with a handrail and balustrade to code. They can be raw industrial, powder-coated architectural, or clad in timber and stone. ### Who it's for Homeowners in Swindon adding an annexe, garden studio, loft or basement; landlords who need a compliant external escape for a first-floor flat; and commercial clients needing external plant-room stairs, mezzanine access or industrial stairs. ### When it's needed When a timber staircase won't span the opening, won't carry the load, or won't survive outside; when the design calls for a modern architectural look; and any time an external staircase is needed as a means of access or escape. ### Why professional help matters A staircase is life-safety kit. Rise and going must be consistent, the handrail must be at the right height, the balustrade must resist the required load, and the whole frame must be tied back to the building properly. Getting any of those wrong is the difference between passing Building Control and being told to take it out. 02 — What happens if you get it wrong ## The four failures we see when steel staircases & external stairs is done cheaply. ### Uneven rise and going A single tread that's 10mm out of pattern is the tread people trip on. Timber-and-carpenter builds outdoors move with the weather; the pattern drifts and the stair becomes unsafe. ### External timber that rots in five winters External timber stairs — even treated — swell, split and rot at the joints. Steel, correctly treated and finished, doesn't. ### Non-compliant handrails and balustrades The wrong handrail height, the wrong baluster spacing, or a rail that a small child can climb — these fail Building Control and, more importantly, put people at risk. ### Wobble at the top and bottom A staircase that isn't tied properly to the structure at head and foot moves under load. It gets worse over time — and by the time you notice it, it's structural. 03 — Our process ## From first call to signed-off installation. 1. Step 1 ### Free site survey We measure the opening, floor-to-floor height, headroom and landing positions on site. We confirm rise, going and headroom against Building Regs. 2. Step 2 ### Design & written quote You get a drawing, a specification (materials, finish, balustrade type, handrail) and a written quote with the guarantee spelled out. 3. Step 3 ### Fabrication in the workshop Stringers cut and welded, treads fitted, handrail and balustrade fabricated, welds ground back, finish applied. 4. Step 4 ### Installation on site Delivered and installed by the same team who quoted the job. Tied properly to the structure, packed level, and finished on site. 5. Step 5 ### Sign-off & written guarantee We walk the stair with you, check the finish, and hand over your written guarantee on fabrication and installation.

This is the technical detail that separates a fabricator from a supplier. Read it, or skim the headings — either way, it's what you're paying for. ### Types of staircase we build Straight-flight external stairs, quarter-turn and half-turn returns with intermediate landings, spiral and helical stairs (subject to space), industrial straight-run access stairs, mezzanine stairs, plant-room and roof-access stairs, fire escapes, and internal architectural stairs with timber, stone or open-riser treads. ### Treads & landings Options include chequer plate, open bar-grating, solid steel plate, open pan treads for timber or stone inserts, and cast-in or bolt-down landings. Tread choice affects grip, drainage, look and cost — we specify to suit the location. ### Handrails, balustrades & compliance Handrail heights and balustrade infills are designed to comply with Approved Document K of the Building Regulations. Infill options include vertical steel balusters, horizontal bars where permitted, stainless-steel wire, or steel-framed glass panels via a trade partner. ### Finishes The right finish for external stairs depends on the environment and the maintenance appetite — we specify an appropriate primer and top-coat system, or a galvanised base, as part of your written quote. ### Residential vs commercial Residential external stairs are usually one flight down to a garden or up to an annexe — priority is fit, look and safety. Commercial and industrial stairs are typically about compliance, load rating and access — we build either way. Regularly installed across Swindon, Wiltshire, Oxfordshire and Somerset. 06 — FAQ ## Straight answers to the questions we're asked most. Not answered here?
