Single-leaf door
One active leaf for standard openings, typically up to about 1.0 – 1.2 m wide. Used for apartment, office, side and service doors.
An aluminium hinged door system is a complete swing door: extruded frame and leaf profiles, glazing, gaskets, threshold, hinges and locks designed to work together. It is the most common door type in buildings because it seals tightly, locks securely and suits everything from apartment entrances to office corridors and hotel balconies. Metline supplies hinged door profiles, thermal-break sections and accessories to door fabricators for project door schedules worldwide.

A hinged door, also called a swing door or side-hung door, rotates on hinges fixed to one vertical edge of the frame. When it closes, the leaf presses against continuous gaskets on all four sides and the lock draws it tight. That compression seal is why a hinged door outperforms a sliding door of the same quality on air tightness, water tightness, sound insulation and security.
In an aluminium system, the frame (outer profile fixed into the wall opening) and the leaf (the moving part) are extrusions designed as a pair. The profiles carry grooves for gaskets, chambers for hinges and lock gear, a glazing rebate, drainage paths and, in insulated systems, polyamide thermal break strips. Hardware is chosen to suit the leaf weight and traffic, and the threshold detail decides how well the door keeps water out at floor level.
Hinged doors are specified for almost every type of opening: front doors and apartment entrances, balcony and terrace doors, office and corridor doors, plant-room and service doors, and the active leaves within shopfront and curtain wall entrances. Because one system can produce all these variants with the same sightlines and colours, project teams often build a whole door schedule from a single hinged door series.
One active leaf for standard openings, typically up to about 1.0 – 1.2 m wide. Used for apartment, office, side and service doors.
Two leaves meeting at a central mullion or with an astragal on the inactive leaf. Gives a wide clear opening for lobbies, terraces and public entrances.
The usual choice for residential entrances and balcony doors in Europe; the leaf is protected from weather when open and hinges are inside for security.
Saves interior space and resists wind-driven rain well because pressure pushes the leaf into its seals. Required on many escape routes, where doors must open in the direction of travel.
Fixed glazed panels beside or above the leaf to bring daylight into halls and lobbies and to fill wide or tall openings. Frame and mullion design must carry the extra wind load.
Narrow-sightline leaves for modern architecture, or deep, multi-chamber thermal break systems with triple glazing for low-energy buildings.
Door and window systems in Europe are mainly extruded in 6060, while 6063 is the usual alloy in North America, India and much of Asia. Both are low-alloy Al-Mg-Si grades with excellent surface quality for anodising and powder coating. The temper is chosen for the stiffness the leaf needs.
| Alloy and temper | Min. tensile Rm | Min. yield Rp0.2 | Typical use |
|---|---|---|---|
| 6060-T5 | 160 MPa | 120 MPa | Light internal doors, beads and trims |
| 6060-T66 | 215 MPa | 160 MPa | Standard European door frame and leaf profiles |
| 6063-T5 | 175 MPa | 130 MPa | Frames and leaves for residential doors |
| 6063-T6 | 215 MPa | 170 MPa | Heavier leaves, entrance doors |
| 6005A-T6 / 6061-T6 | 260 – 270 MPa | 225 – 240 MPa | Reinforcing profiles, tall mullions |
Minimum values are typical EN 755-2 / ASTM B221 limits for wall thickness up to about 3 – 5 mm; exact limits depend on section and thickness.
External doors are tested as complete units. In Europe, EN 14351-1 is the product standard behind CE and UKCA marking, and each property is declared as a class. In North America, swing doors are rated under the North American Fenestration Standard (AAMA/WDMA/CSA 101/I.S.2/A440) with a performance class and design pressure. The table shows what each test means and the typical range for a good aluminium hinged door.
| Property | European test / classification | Typical good hinged door | North America |
|---|---|---|---|
| Air permeability | EN 1026 / EN 12207, classes 1 – 4 | Class 3 – 4 | ASTM E283 |
| Watertightness | EN 1027 / EN 12208, classes 1A – 9A and E | 4A – 8A (higher for outward-opening) | ASTM E331 / E547 |
| Wind resistance | EN 12211 / EN 12210, classes 1 – 5 (A, B, C deflection) | C3 – C5 | ASTM E330 |
| Thermal transmittance | EN ISO 10077-1/-2 (Ud) | 1.2 – 2.0 W/m²K (thermal break) | NFRC 100 U-factor |
| Acoustic | EN ISO 10140 / EN ISO 717-1 (Rw) | 30 – 40 dB depending on glass | ASTM E90 (STC, OITC) |
| Mechanical durability | EN 12400, classes 1 – 8 | Class 5 – 8 for high-traffic doors | Hardware cycle testing |
| Burglar resistance | EN 1627, RC 1 – RC 6 | RC 2 – RC 3 for entrances | ASTM F476 / F842 |
Doors on escape routes also need hardware tested to EN 179 (emergency exit devices) or EN 1125 (panic bars), and door closers to EN 1154. Fire and smoke doors are a separate product class tested to EN 1634 and EN 16034; standard hinged door systems are not fire-rated unless certified as such.
Barrel or butt hinges clamped into the profile chambers, surface-fixed 3D-adjustable hinges, or concealed hinges for a clean look. Choose by leaf weight and size, and to EN 1935 grades for durability; use three hinges on tall or heavy leaves.
Single-point locks for internal doors; multi-point locks with hooks or rollers at top, middle and bottom for external doors, which pull the leaf evenly into its seals and resist forcing.
Lever-lever, lever-pull or panic hardware, with profile cylinders to EN 1303 and anti-snap options on entrances.
Standard drained thresholds for exposed doors; low or flush thresholds (often 20 mm or less) for accessibility, which need more care with drainage and sill detailing.
Continuous EPDM gaskets in two or three lines, corner-moulded or vulcanised at joints, plus a drop seal or brush at the threshold where a low sill is used.
Overhead or concealed closers for public doors, and restrictors or stays to stop wind slamming external leaves.
Hardware and profile must be compatible: hinge and lock positions are machined into specific chambers of the profile, and the leaf weight (frame plus glass) must be within the hinge rating. Double-glazed leaves of 1.0 × 2.4 m weigh roughly 60 – 80 kg, and triple-glazed or laminated leaves considerably more.
| Finish | Typical specification | Notes |
|---|---|---|
| Powder coating | AAMA 2603 / 2604 or Qualicoat Class 1 – 2; 60 – 80 µm | Any RAL colour, matt to gloss; standard choice |
| PVDF liquid coating | AAMA 2605 or Qualicoat Class 3; about 25 – 40 µm | Highest colour retention for façades and coastal sites |
| Anodising | EN ISO 7599 / Qualanod, class 15 – 25 µm | Metallic look and hard, abrasion-resistant surface |
| Wood-grain | Sublimation on powder base coat | Timber appearance without maintenance |
| Dual colour | Different inside and outside colours | Possible on thermal break profiles, which are coated before assembly |
| Factor | Hinged door | Sliding door | Bifold door |
|---|---|---|---|
| Space needed | Swing arc inside or outside | None beyond the frame | Space for stacked leaves |
| Clear opening | Full leaf width; double leaves for wider | About half the frame width (more with lift-slide pockets) | Almost the full opening |
| Air and water tightness | Highest (compression seals) | Lower (brush or lift-slide seals) | Good to medium, depends on hardware |
| Security | High with multi-point locks | Good with hook locks | Good, more joints to secure |
| Maintenance | Low: hinges and lock | Rollers and tracks | Hinges, rollers and tracks |
| Best for | Entrances, corridors, balcony doors, door schedules | Patios and wide glazed openings | Opening a room fully to a terrace |
For wide patio openings see sliding door systems and bifold doors; for paired entrance leaves see aluminium double doors.
Entrance and balcony doors in thermal break systems, specified once and repeated across hundreds of units.
Glazed corridor, meeting-room and side entrance doors, with closers and access-control hardware.
Guest-room balcony doors with good acoustic glass, and paired lobby doors with sidelights and transoms.
Robust, high-cycle doors with panic or emergency hardware on escape routes and laminated safety glass.
Inward-opening doors are common for homes and balconies because the hinges are inside and the leaf is sheltered when open. Outward-opening doors save interior space, resist wind-driven rain better and are required on many escape routes. Decide per door, taking into account threshold design and local code.
When a hinged leaf closes, the lock pulls it against continuous compression gaskets on all four sides. Sliding doors rely on brushes or lift-slide seals at moving joints, which are inherently leakier. A good hinged door typically reaches higher air and water classes from the same system family.
With a polyamide thermal break, multi-chamber profiles and Low-E double or triple glazing, aluminium hinged doors typically reach door U-values of about 1.2 – 2.0 W/m²K, depending on system depth, glass and size.
It depends on the hinge type and number. Standard clamped barrel hinges suit typical residential leaves, while heavy-duty and concealed hinges are rated for heavier glazed leaves. Always compare the leaf weight, including glass, with the hinge manufacturer's rating, and use three hinges on tall leaves.
Usually 6060-T66 in European systems and 6063-T5 or T6 elsewhere, extruded to EN 755 or ASTM B221. Both give a fine surface for powder coating and anodising; reinforcing profiles may use 6005A or 6061.
