Custom Aluminium Bi-Fold Doors

Fenghui is an experienced aluminium bi-fold doors manufacturer supplying made-to-measure door systems for builders, developers, window and door distributors, architectural contractors and commercial project buyers.

Fenghui was established in 2000 and operates a 200,000 m² manufacturing base with annual aluminium window and door output of approximately 100,000 m². Our integrated production capabilities help maintain consistent dimensions, finishes and operating quality across repeated project units.

Our project supply capabilities include:

Whether you are sourcing aluminium bi-fold glass doors for a luxury residential development or aluminium bi-fold patio doors for a hotel, restaurant or villa project, Fenghui can coordinate the complete aluminium door specification around your schedule.

 

Select the Right Panel and Opening Configuration

The panel layout affects the clear opening, stacking space, daily access and overall appearance of the completed door. Buyers should confirm the layout before approving production drawings.

Configuration Decision Common Project Options What the Buyer Should Confirm
Panel quantity Three, four, five, six or project-specific multi-panel layouts Overall opening width, individual panel weight and required clear opening
Stacking direction All panels left, all panels right or panels divided between both sides Available stacking space, columns, furniture and circulation routes
Opening direction Inward folding or outward folding Interior floor space, patio layout, weather exposure and external walkways
Everyday access Integrated traffic door or complete folding operation Frequency of access and whether the whole system must be opened each time
Threshold direction Weather-resistant or project-specific low-threshold solution Drainage, finished floor level, accessibility and exposure to wind-driven rain
Panel distribution Symmetrical or asymmetrical arrangement Architectural elevation and preferred location of the primary access leaf

Typical panel arrangements are subject to the final door dimensions, glass weight, hardware capacity and nominated performance requirements. Fenghui reviews these factors together rather than selecting the panel count from opening width alone.

For projects where a large glazed opening is required but panel stacking space is limited, buyers can also compare our thermal break sliding doors and non-thermal break sliding doors.

 

Specify Each Door Around the Building Conditions

Aluminium bi-fold patio doors should not be specified only by width, height and colour. External exposure, wind pressure, glazing weight, drainage and frequency of use can all affect the appropriate configuration.

Project Requirement Recommended Specification Direction Information Required for Review
Exposed exterior opening Weather-resistant sill, suitable sealing and project-rated configuration Project location, elevation, exposure and nominated design wind pressure
Improved thermal comfort Appropriate frame and insulated glass combination Required U-value, SHGC, climate zone or energy consultant specification
Acoustic control Laminated or acoustic insulated glass configuration Required Rw, STC or external noise conditions
Safety-sensitive glazing Tempered or laminated safety glass selected by application Glass dimensions, door location and applicable glazing standard
Coastal environment Suitable coating specification and corrosion-resistant hardware direction Distance from the coast and environmental exposure category
High-traffic commercial use Durable operating hardware and convenient traffic-door layout Expected usage, access route and opening frequency
Privacy or solar control Obscure, tinted, Low-E or project-selected glass Privacy level, orientation and solar-control requirement
Coordinated façade package Matching colours, glass appearance and hardware selection Door and window schedule, finish reference and elevation drawings

 

Australian Project Compliance Support

For external aluminium bi-fold doors used in Australian buildings, AS 2047 covers windows and external glazed doors, including bi-fold door configurations, while AS 1288 establishes requirements for selecting and installing glass in buildings.

Frequently Asked Questions

Can Fenghui manufacture custom-sized aluminium bi-fold doors?

Yes. Door dimensions are developed around the approved project opening rather than limited to a small selection of retail sizes. Final panel sizes and quantities are subject to glass weight, hardware capacity and required structural performance.

Can the doors be used as exterior patio doors?

Yes. Aluminium bi-fold exterior doors can be configured for patios, alfresco openings and other indoor-outdoor connections. External applications require the correct threshold, drainage, sealing, glass and performance specification for the exposure conditions.

Can different configurations be supplied within one project?

Yes. A project may include different widths, panel quantities, stacking directions, glass types and colours. Each unit should be identified clearly in the door schedule and approved drawings.

What should buyers compare among aluminium bi-fold doors manufacturers?

Buyers should compare more than profile appearance and price. Important factors include performance evidence for the proposed configuration, profile and glass production control, hardware durability, drawing support, specification accuracy, batch consistency, packaging, lead time, warranty scope and after-sales response.

What are the MOQ and production lead time?

MOQ and lead time depend on door dimensions, quantities, glass make-up, finish, hardware and whether the order is combined with other aluminium windows and doors. Providing a complete schedule allows Fenghui to calculate a more reliable production and delivery plan.

Maintenance Tips

Twice-yearly care keeps bi-fold doors gliding smoothly, sealing tightly, opening fully, and lasting for years. Contact a specialist for adjustments or persistent issues.

01
Clean frames & glass

Use mild detergent/water or glass cleaner + soft cloth. Fold panels fully open for safe access to both sides. 1–2 times yearly (more if dusty/coastal).

02
Clear tracks & pivots

Brush or vacuum dirt, dust, leaves from top/bottom tracks, hinges, and pivot points. Keep channels free to prevent binding.

03
Lubricate hardware

Apply silicone-based lubricant to rollers, pivots, hinges, tracks, and multi-point locking mechanisms every 6–12 months (or when movement feels stiff). Wipe excess.

04
Inspect seals & weatherstripping

Check gaskets and brushes for cracks, flattening, or gaps. Clean gently; replace damaged ones to stop drafts, leaks, and noise.

05
Test alignment & operation

Fold/unfold fully; ensure smooth, even movement and secure locking at every point. If panels drag, bind, or misalign, do not force—call a professional for adjustment.

06
Clean insect screens (if fitted)

Remove detachable screens; rinse with water, brush gently, dry, and reinstall.

07
Check drainage

Clear any drainage holes/slots in bottom track/sill to prevent water pooling.
