We do not simply supply standard doors manufactured by someone else.
We manufacture bespoke steel door units around the dimensions, architectural character and practical requirements of each individual property. Our team manages the complete process—from the initial design consultation and detailed site survey to steel fabrication, specialist glazing, finishing, delivery and professional installation.
Every door is created to become part of the building rather than merely being fitted into it.
Whether the project requires a single glazed garden door, an impressive double entrance, steel French doors, an oversized pivot door, matching sidelights, a glazed fanlight or a complete steel-framed frontage, Swift Glazing can develop a made-to-measure solution with a distinctive architectural presence.
Our external steel doors combine precision manufacturing, refined detailing, specialist glazing knowledge and experienced installation to create entrances that feel substantial, elegant and completely individual.
More Than a Door. A Defining Architectural Feature.
The entrance to a property establishes its identity before anyone steps inside.
A beautifully proportioned steel door can transform an ordinary opening into a confident architectural statement. Slim framing creates expansive areas of glass. Carefully positioned glazing bars introduce rhythm and symmetry. Substantial handles and refined hardware create a sense of quality that can be seen and felt.
External steel doors are particularly effective where a project demands strength without visual heaviness. The inherent rigidity of steel allows carefully engineered profiles to create refined framing around substantial glazed areas. The result is a door that can appear slim and elegant while retaining a strong, purposeful character.
Steel works equally well within contrasting architectural styles.
Against traditional brickwork, stone or period façades, it can create a sophisticated balance between heritage architecture and contemporary design. Within a modern extension, it can reinforce clean lines and connect internal spaces with gardens, terraces and courtyards. In a commercial property, it can create a distinctive entrance that feels permanent, professional and unmistakably premium.
At Swift Glazing, every proportion is considered:
The width and height of each door leaf.
The relationship between the door and the surrounding.
The position of horizontal and vertical glazing bars.
The balance between glass and steel.
The alignment of handles, locks, and hardware.
The relationship between the entrance and the internal floor.
The appearance of the door from both inside and outside.
Manufactured by Swift Glazing
Swift Glazing is not simply an installation company or an online door retailer.

The steel frame is not designed without considering the glass. The glass is not ordered without considering its weight, edge clearances and support. The hardware is not selected without considering the size, use and configuration of the door.
Complete Control From Steel Profile to Final Installation
Using separate companies for design, fabrication, glazing and installation can create gaps in responsibility. An incorrect deduction in the manufacturing size can affect the installation. An unsuitable glass specification can increase weight beyond the intended hardware capacity. Poor coordination between the threshold and finished floor can affect drainage, accessibility and weather sealing. Swift Glazing provides one coordinated route through the project.
Swift Glazing provides a coordinated route through the project.
Specialist Team
Our fabrication, glazing and installation knowledge is brought together from the beginning.
Agreed Design
Dimensions, panel arrangements, glazing bars, glass, colours and hardware are agreed before production.
Manufacturing Process
The doors are manufactured around the approved project specification rather than modified from an unsuitable standard product.
Point of Responsibility
Our team coordinates the manufacture, glazing, delivery and installation of the complete unit.
Consistent Standard
The same attention to detail is applied to the parts customers see and to the technical details concealed within the finished installation.
Types of External Steel Doors
Every property requires a different balance of access, daylight, privacy, and visual impact.
Swift Glazing manufactures a wide range of external steel door configurations.
External Single Steel Doors
A single steel door can create an elegant entrance without dominating the surrounding elevation. Single external steel doors are suitable for main entrances, side entrances, garden access, courtyards, basement entrances, home offices, studios, utility areas and commercial properties. The door may be fully glazed, partially glazed or combined with solid steel sections. It can also be positioned beside a fixed glazed panel to increase natural light and strengthen the overall composition.
External Steel French Doors
Steel French doors create a balanced and timeless entrance using two hinged door leaves that meet in the centre. They are particularly suitable for kitchen extensions, dining rooms, living rooms, patios, gardens, courtyards, period-property renovations and premium commercial premises.The arrangement may use two equal leaves or a primary opening leaf with a secondary leaf that is released when a wider opening is required. Matching fixed panels and fanlights can be incorporated to create a complete glazed wall.
External Steel Doors With Sidelights
Fixed sidelights increase natural light and create a more substantial entrance composition. They may be positioned on one side, on both sides, as equal symmetrical panels, as asymmetrical panels, as full-height glazed sections or with solid lower steel panels. The glazing bars can continue across the door and sidelights to make the entire frame appear as one unified architectural element.
External Steel Doors With Fanlights
A fanlight is positioned above the door and can be used to accommodate a tall opening or increase natural light within an entrance hall. Fanlights may be fully glazed, divided with steel bars, arched, rectangular, fixed or designed to align with surrounding windows.
External Steel Pivot Doors
A pivot door rotates using pivot hardware installed at the head and base rather than conventional hinges positioned at the side. Pivot doors are frequently selected for larger, more dramatic entrances where the door is intended to become a central architectural feature. The design must account for the door dimensions, glass weight, frame construction, pivot position, threshold, weather sealing, locking, floor construction, internal and external clearances and frequency of use. A successful pivot door requires precise engineering and should be developed as a complete system rather than treated as a conventional door with alternative hinges.
External Steel Bifold Doors
Steel bifold doors use several connected leaves that fold towards one or both sides of an opening. Steel bifold doors use several connected leaves that fold towards one or both sides of an opening. Steel bifold doors use several connected leaves that fold towards one or both sides of an opening.
External Steel Sliding Doors
Sliding steel doors provide an alternative where a hinged door would interfere with furniture, circulation or external space. Possible arrangements include one sliding door beside a fixed panel, two central sliding doors, multi-panel sliding systems or large-format glazed steel screens. External sliding doors must use systems designed to address water, air leakage, drainage, locking and regular operation.
Arched External Steel Doors
Arched doors bring depth and individuality to both traditional and contemporary buildings. They are particularly effective in period properties, listed-building renovations, courtyard entrances, converted industrial buildings, heritage projects and bespoke residential developments. The arched frame, door leaves and glass must be manufactured around accurate dimensions, templates or approved drawings.
Partially Glazed Steel Doors
A partially glazed design can provide additional privacy while retaining the elegance of steel framing. The door may incorporate a solid lower section, central glazing, narrow vertical glazing, decorative panels, obscure glass, side glazing, a glazed fanlight or bespoke geometric divisions
Complete Steel Entrance Screens
For larger openings, the door can become part of a complete steel-framed entrance screen incorporating single or double doors, fixed side panels, fanlights, corner returns, matching windows, lower steel panels and coordinated glazing-bar layouts.
Glass defines much of the visual character of an external steel door, but it also influences safety, weight, thermal efficiency, privacy, security, solar control and acoustic performance. Swift Glazing brings specialist glazing knowledge directly into the door-manufacturing process. Rather than treating the glass as a decorative infill, we consider it as an engineered component of the complete doorset.
The Heritage Grid Collection
Traditional rectangular glazing divisions inspired by historic metal windows and early industrial architecture. Best suited to Victorian properties, Edwardian houses, warehouse conversions, period extensions and heritage-style renovations.
The Minimal Collection
Large uninterrupted glass panels with restrained framing and minimal glazing bars.
Best suited to contemporary homes, modern extensions, minimalist architecture, luxury apartments and high-end commercial spaces.
The Art Deco Collection
Strong geometry, balanced proportions, stepped details and distinctive glazing arrangements. Best suited to period apartments, statement entrances, restaurants, hotels and design-led refurbishments.
The Industrial Collection
Dark steel framing, regular grids, robust hardware and clear or textured glass.
Best suited to loft properties, studios, commercial units, warehouse-style developments, restaurants and bars.
The Grand Entrance Collection
Oversized doors, sidelights, fanlights and long architectural handles. Best suited to luxury homes, large residential entrances, hotels, showrooms, reception buildings and high-end developments.
The Arched Collection
Soft curved heads combined with slim steel framing. Best suited to period properties, courtyards, Mediterranean-style projects, heritage properties and bespoke architectural openings.
The position and proportion of the glazing bars determine the visual identity of a steel door.
A well-designed layout should feel balanced across the door leaf, fixed panels and surrounding elevation.
Available arrangements can include equal rectangular grids, tall vertical divisions, narrow horizontal divisions, square glazing patterns, large central panes, asymmetrical arrangements, Art Deco-inspired geometry, heritage-style multi-pane patterns, minimal single-pane designs and custom arrangements based on architectural drawings.
Where doors are installed beside steel windows, we can coordinate the horizontal and vertical lines so the entire elevation appears unified. The glazing-bar design must be approved before fabrication. Once the steelwork has been welded and powder coated, substantial design changes are generally no longer practical.
Colour, Texture and Powder-Coated Finishes
Black external steel doors remain an enduring architectural choice, but a premium bespoke door should never be limited to one standard colour.
The frame can be selected to complement or contrast with brickwork, stone, render, timber cladding, existing windows, interior finishes, architectural metalwork, roofing, balustrades and landscape design.
Popular colours include jet black, anthracite grey, graphite grey, dark bronze, bronze-black, off-white, traffic white, heritage green, olive green, deep brown, warm grey and bespoke RAL colours.
Available surface appearances may include matt, satin, fine texture, gloss, metallic effects and specialist architectural finishes.
The preparation beneath the visible coating is as important as the colour itself. External steelwork must be appropriately prepared and finished for its intended environment. Coastal sites, heavily exposed elevations and aggressive environments may require additional corrosion-protection consideration.
Handles, Locks and Architectural Hardware
Hardware should feel integrated into the door—not added after the design has been completed. The handle, lock, hinge and closer must suit the proportions, weight and operating demands of the doorset.

Hardware must be selected before manufacture whenever the frame requires internal reinforcement, cut-outs, drilling or specialist preparation.
Steel provides a robust foundation, but the security of an entrance cannot be judged by the frame material alone. The performance of an external doorset depends on the relationship between the door leaf, outer frame, glass, glazing retention, locks, cylinders, hinges, hardware fixings, frame fixings, side panels, fanlights, threshold and installation substrate.
Security requirements should be identified before manufacturing begins.
Depending on the project, possible enhancements may include laminated security glass, multi-point locking, enhanced cylinders, internal glazing, reinforced lock preparation, heavy-duty hinges, protected fixings, restricted opening, access-control equipment, door closers and additional locking points.
Weather Performance, Seals and Drainage
An external steel door must withstand conditions that an internal door will never encounter.
The system may be exposed to wind-driven rain, temperature changes, strong sunlight, freezing conditions, moisture, dirt, debris, repeated opening and differences in internal and external pressure.
A successful external door requires a coordinated weather-management strategy.
This may include perimeter seals, glazing gaskets, weathered thresholds, drainage channels, pressure-equalised glazing, proper sill projections, external sealant, controlled water run-off, appropriate floor levels, correct door-leaf compression and suitable head and jamb details. A fully exposed entrance facing prevailing weather may require a different design from a door installed beneath a canopy or inside a sheltered courtyard.
Site exposure must be assessed before the final configuration is approved.
Low, Flush and Accessible Thresholds
Threshold design affects more than appearance.
It influences water management, accessibility, door sealing, floor transitions, drainage, trip risk, internal flooring and external paving levels. Possible arrangements include standard rebated thresholds, low thresholds, flush-style thresholds, accessible thresholds, weathered thresholds, thresholds with external drainage channels and bespoke interfaces with stone or tiled floors. A completely level appearance must still be designed to control water effectively. For new entrances and commercial projects, access requirements should be considered from the beginning of the design process.
External steel doors can transform the way a home looks, feels and connects with its surroundings.
Garden and Patio Entrances
Glazed steel doors create a strong visual connection between internal living areas and gardens, terraces or courtyards. They are particularly effective in open-plan kitchens, dining rooms, living rooms, rear extensions, side-return extensions, garden rooms and basement living spaces.
Main Entrance Doors
A bespoke steel front door can create a powerful first impression while introducing natural light into the entrance hall. The design may include fixed sidelights, fanlights, privacy glass, solid lower panels, statement handles, custom glazing bars, electronic access and bespoke colours.
Period-Property Extensions
Steel doors can create a carefully controlled contrast between historic architecture and modern additions. The slender proportions allow the new work to feel refined rather than visually heavy.
Courtyard Doors
Steel-framed doors are particularly effective around internal courtyards, lightwells and enclosed gardens.
Basement Entrances
Basement and lower-ground entrances require careful attention to drainage, external levels, security and weather exposure.
Roof Terraces and Balconies
Door swing, threshold levels, guarding, drainage and external space must be coordinated before manufacture.
Garden Offices and Studios
Thermally appropriate external steel doors can bring daylight and architectural quality to detached workspaces and studios.
Swift Glazing manufactures and installs steel doors for restaurants, hotels, offices, retail premises, showrooms, galleries, studios, bars, hospitality venues, apartment developments, communal entrances, reception buildings, educational properties, listed commercial buildings and converted industrial properties.
Commercial entrances must create the right first impression while withstanding more intensive use. Commercial doors may require heavy-duty hinges, door closers, floor springs, access-control systems, electric locking, panic or escape hardware, durable pull handles, safety manifestation, increased glass specifications, accessible thresholds, out-of-hours installation, temporary site protection, RAMS and specialist lifting equipment.
The expected frequency of use should always be discussed before hardware is specified.
The complete arrangement may include single entrance doors, double entrance doors, fixed glazed screens, fanlights, lower steel panels, architectural glazing bars, door closers, access-control systems, manifestation, laminated glass, solar-control glass, acoustic glass and coordinated signage zones. The design must consider door opening direction, clear opening width, emergency escape requirements, glass safety, security, thresholds, hardware, floor levels, surrounding construction and maintenance access.
Initial Consultation
The process begins with an understanding of the project.
Customers should provide the full site address, photographs from inside and outside, approximate dimensions, preferred door style, number of opening leaves, examples of preferred glazing-bar layouts, frame colour, glass preference, hardware preference, architectural drawings where available, required completion date and information about site access.
Site Survey
Our team inspects the opening and records the information required to develop the doorset.
The survey may include structural opening dimensions, internal and external floor levels, wall construction, existing frame details, access route, door swing, surrounding finishes, exposure to weather, head and sill conditions, drainage requirements, lifting considerations, existing services and installation restrictions.
Design Development
The door arrangement is developed around the surveyed opening and the customer’s design preference.
Decisions include overall dimensions, number of doors, opening direction, glazing-bar layout, frame profile, glass specification, handle style, locking system, threshold, colour, fixed side panels and fanlights.
Drawing Approval
For bespoke projects, manufacturing drawings may be prepared for review.
The customer or appointed project representative should check dimensions, opening direction, panel arrangement, bar locations, handle position, glass type, colour and threshold arrangement. Manufacturing begins after the required design information has been approved.
Steel Fabrication
Steel profiles are cut, prepared and assembled according to the approved design.
The fabrication process may include cutting, mitring, welding, grinding, joint finishing, glazing-bar installation, hinge preparation, lock preparation, hardware reinforcement, drainage preparation, frame assembly and quality checking.
Surface Preparation and Powder Coating
The fabricated units are prepared before receiving their specified architectural finish.
Glass Manufacture
Glass is manufactured according to the approved sizes and specification.
Any required toughening, laminating, drilling, notching, coating or decorative processing must be completed at the appropriate stage.
Workshop Assembly and Glazing
Where appropriate, the units are assembled and glazed before delivery.
Delivery and Installation
The doors are transported to site with suitable protection and installed by our experienced team.
Adjustment and Handover
Following installation, the doors are checked for alignment, clearances, opening, closing, locking, seal compression, handle operation, closer operation and general finish.
External steel doors can be large and extremely heavy, particularly when incorporating double-glazed, laminated or oversized glass panels.
Installation planning may require two or more experienced operatives, glass suction equipment, mechanical glass lifters, material lifts, hoists, cranes, mobile access equipment, temporary barriers, pedestrian management, protected access routes, out-of-hours, coordination with builders, temporary weather protection and site-specific RAMS.
The frame must be installed level, plumb, square, securely fixed, correctly packed, properly sealed, aligned with surrounding finishes and coordinated with the floor and threshold levels.
Specialist lifting equipment, structural alterations, plastering, rendering, flooring and decoration are not automatically included unless specifically stated in the quotation.
A premium external door should be maintained as an architectural product rather than ignored until a fault develops.
Recommended care can include cleaning frames with a mild non-abrasive solution, cleaning the glass regularly, keeping thresholds clear, removing debris from drainage channels, checking external sealant, inspecting gaskets, checking handle fixings, lubricating approved moving components, checking lock operation and inspecting door alignment.
Avoid abrasive cleaning pads, strong acidic or alkaline cleaners, unapproved solvents, painting over drainage openings, drilling the finished frame without approval, allowing plaster or cement to remain on the coating and forcing a door that is not operating correctly.
