Product Description

We are a professional manufacturer of aluminum folding doors, the multi-panel bi-fold door system that opens up to 90% of the wall opening, connecting indoor and outdoor spaces seamlessly. Featuring 6060-T6 thermal break profiles, heavy-duty folding hinges, stainless steel rollers and multi-point locking, our folding doors combine large glass panels, smooth operation and reliable security. Available in top-hung and bottom-rolling systems with optional low threshold, fly screen and fixed + folding combinations. Fully customizable in size, color and glazing. NFRC certified, OEM/ODM supported. Contact us for a quotation, or send your drawings for a custom quote.

Key Features

1. Up to 90% Opening — panels fold and stack neatly to one side, opening almost the entire wall for seamless indoor-outdoor flow.

2. Large Glass Panels — full-height glazing provides panoramic views and floods the room with natural light.

3. Smooth Folding Operation — heavy-duty hinges with stainless steel rollers glide smoothly along the track; top-hung and bottom-rolling systems available.

4. Thermal Break Energy Efficiency — PA66GF25 thermal break profiles with optional Low-E or triple glazing achieve a U-Factor as low as 1.2 W/(m²·K).

5. Multi-Point Locking Security — multi-point locks on the active panels resist prying and secure the door firmly when closed.

6. Weather Resistance — EPDM gaskets and weatherstripping brush seals keep out wind, rain and dust.

7. Optional Low Threshold — level access allows barrier-free passage and easy cleaning of the track area.

8. Flexible Configurations — 2 to 12 panels per opening; fly screen and fixed + folding combinations available; OEM/ODM supported.

FAQ

Q1: How much of the opening can be opened?

A: Folding doors can open up to about 90% of the wall opening, as the panels fold and stack neatly to one or both sides.

Q2: How many panels can be used?

A: Typically 2 to 12 panels per opening, depending on width and panel weight. Panel width is usually 500–900mm; we can design the layout from your drawings.

Q3: What is the difference between top-hung and bottom-rolling systems?

A: In a top-hung system the weight is carried by the overhead track; in a bottom-rolling system the panels run on bottom rollers. We recommend the system based on panel size, weight and local wind conditions.

Q4: Is a low threshold available?

A: Yes. A low-threshold option provides level access for wheelchairs, strollers and elderly users, with a drainage channel to prevent water ingress.

Q5: What is the minimum order quantity (MOQ)?

A: custom MOQ depends on configuration — confirm with our sales team.

Q6: What is the production lead time?

A: Around 15–25 days for standard doors and 25–35 days for custom orders; partial shipments can be arranged for large orders.

Q7: Do you support OEM/ODM?

A: Yes. We offer private label, logo printing, custom packaging, and new product development from customer drawings.

Q8: What is the warranty? How is after-sales handled?

A: 3 years on profile structure and 5 years on hardware. Report issues with photos and we will provide a solution within 48 hours.

Q9: What glazing options are available?

A: Double glazing, triple glazing, Low-E, laminated, tempered, frosted and built-in blinds. We can recommend the right configuration for your local climate.

Q10: How do you guarantee quality?

A: We use qualified suppliers for profiles, glass and hardware, run QC throughout production, and inspect every door before shipment with a certificate of conformity. Test reports are available.

Q11: Can I get a sample?

A: Yes. Samples / sample doors are available free or at cost (freight paid by customer); the sample fee is deductible from the first order.
