| Hardware | Multi-point locking system | Locks the door at several points along the frame, typically using a central handle-operated mechanism with additional bolts or hooks. | Exterior entrances, patio doors, and locations requiring improved resistance to forced opening. | Confirm compatibility with the door profile, frame depth, cylinder type, and local security requirements. | High security |
| Hardware | Single-point latch and deadbolt | Uses a conventional latch with a separate deadbolt. It is simpler and generally easier to service. | Interior French doors, low-risk areas, and projects with a controlled budget. | Use a properly reinforced strike plate and verify that the frame can support the selected lockset. | Basic to moderate |
| Hardware | Adjustable hinges | Allows limited height, compression, or lateral adjustment to help maintain even gaps after installation and seasonal movement. | Large or frequently used door leaves and projects where accurate alignment is important. | Check the hinge load rating and the maximum door sash weight supported by the complete hinge set. | Highly practical |
| Hardware | Concealed hinges | Hinges are hidden when the door is closed, creating a cleaner appearance while preserving controlled movement. | Contemporary interiors and minimalist architectural designs. | Confirm opening angle, adjustment range, maintenance access, and compatibility with the aluminum profile system. | Design focused |
| Hardware | Floor or head jamb door closer | Controls closing speed and can help return a door leaf to the closed position. Floor-mounted units are commonly used with pivot-style systems. | Commercial interiors, high-traffic areas, and doors that must close consistently. | Match the closer strength to the door size, weight, wind exposure, and intended opening angle. | Traffic control |
| Finishes | Powder coating | A dry finish cured onto aluminum, offering a broad range of colors and a durable surface for normal indoor and outdoor use. | Most residential and commercial projects requiring color consistency and low routine maintenance. | Specify the color standard, gloss level, pretreatment, and suitability for the project’s exposure conditions. | Versatile |
| Finishes | Anodized aluminum | Electrochemically forms a hard aluminum-oxide surface. It preserves a metallic appearance and does not create a separate paint film. | Modern buildings, high-touch areas, and designs that emphasize the natural appearance of aluminum. | Review the selected anodized color, batch consistency, cleaning method, and expected appearance under different lighting. | Durable appearance |
| Finishes | Wood-look finish | Uses a decorative pattern to provide a timber-style appearance while retaining the dimensional stability and maintenance benefits of aluminum. | Traditional, transitional, and hospitality projects seeking a warmer visual effect. | Check pattern direction, color variation, edge treatment, and whether matching accessories are available. | Warm aesthetic |
| Finishes | Dark matte finish | Provides a contemporary appearance and can emphasize slim frame lines. Dark surfaces may absorb more solar heat than light colors. | Modern façades, industrial interiors, and high-contrast architectural schemes. | Consider solar exposure, surface temperature, cleaning marks, and the finish’s exterior durability classification. | Modern style |
| Security | Laminated safety glass | Consists of glass layers bonded with an interlayer. If broken, the interlayer helps retain fragments and can delay penetration. | Ground-floor doors, glazed entrances, areas exposed to impact risk, and projects prioritizing safety. | Verify the required safety-glazing classification, thickness, acoustic needs, and compatibility with the frame rebate. | Enhanced safety |
| Security | Tempered safety glass | Heat-treated glass with increased resistance to thermal stress and impact compared with ordinary annealed glass. When broken, it generally granulates into small pieces. | Doors where thermal stress and impact safety are key considerations. | Tempered glass cannot normally be cut or modified after treatment; confirm all dimensions and holes before production. | Impact resistant |
| Security | Security cylinders and protected escutcheons | Can help reduce risks associated with unauthorized key duplication, cylinder attack, and direct access to the lock body. | Main entrances, multi-occupancy buildings, and projects with controlled key management. | Use a cylinder length suited to the door thickness and specify an escutcheon that protects without obstructing operation. | Access control |
| Security | Restricted opening hardware | Includes opening limiters, restrictors, or child-safety devices that control the maximum opening distance. | Upper floors, family homes, schools, and locations where uncontrolled opening is a concern. | Ensure the device can be released for emergency egress where required and does not interfere with cleaning or maintenance. | Safety focused |
| Opening Style | Inswing hinged French doors | Both leaves open toward the interior. Furniture and interior circulation must allow sufficient clearance. | Protected exterior openings, sheltered balconies, and rooms where the exterior landing is limited. | Allow for furniture clearance, drainage at the threshold, weather seals, and local egress requirements. | Space dependent |
| Opening Style | Outswing hinged French doors | Both leaves open toward the exterior, preserving interior floor area but requiring adequate outdoor clearance. | Compact interiors, patios, and openings where indoor space is valuable. | Check wind exposure, exterior circulation, threshold drainage, hinges, and whether the door can obstruct walkways. | Space efficient |
| Opening Style | One active leaf and one inactive leaf | One leaf is used for normal passage while the second leaf remains secured with flush bolts until a wider opening is needed. | Residential entrances, dining areas, and openings that need occasional wide access. | Confirm flush-bolt reach, handle coordination, astragal design, and the clear opening of the active leaf. | Flexible |
| Opening Style | Two independently active leaves | Both leaves can be operated separately, providing flexible everyday access and a wider opening when required. | High-traffic areas, accessible routes, and rooms connecting to large terraces or gardens. | Coordinate the locking sequence, meeting stile, weather seals, and required clear width for accessibility. | Highly flexible |
| Opening Style | Center-hung pivot French doors | Door leaves rotate around pivot points rather than conventional side hinges. This can support large-format visual designs. | Statement entrances, spacious interiors, and projects using a strong architectural feature door. | Confirm floor and head conditions, pivot load capacity, swing clearance, closing control, and threshold detailing. | Architectural |
| Project Planning | Thermal-break aluminum frame | Uses a low-conductivity separator between interior and exterior aluminum sections to reduce heat transfer through the frame. | Conditioned spaces, energy-conscious buildings, and locations with significant outdoor temperature variation. | Review whole-door thermal performance, glazing specification, air leakage, water resistance, and installation quality. | Energy efficient |
| Project Planning | Low threshold or flush threshold | Reduces the step at the doorway and can improve accessibility, although fully flush details require careful water management. | Accessible homes, indoor-outdoor transitions, and contemporary floor-level designs. | Balance accessibility with weather protection, drainage, sill support, floor tolerances, and local building regulations. | Accessibility focused |
