Aluminum Frame Heavy Duty Bi-Folding Door for Balconies
Experience versatility with our diversified folding and opening methods. Our doors boast a stylish and beautiful appearance, are easy to slide and open, waterproof, moisture-proof, have excellent sound insulation, and are highly durable.
Equipped with imported hardware from Kerssenberg, our doors come with anti-pinch rubber strips to ensure the safety of the elderly and children.
Secure with Key Lock Feature

Designed to withstand the elements, the lower pulley with ball bearing and stainless steel slide rail prevent wind, dust, and rainwater from seeping into your room.

Safety First: A Unique Set of Safety Features
Prevent accidental hand pinching with our thoughtfully designed safety mechanisms.

Unlike traditional sliding doors, which only allow you to open half the area, our folding doors open entirely, creating expansive, panoramic openings that seamlessly blend your indoor space with your garden or yard. Featuring multiple connected panels, these bifold doors open in a concertina style, folding neatly to one side. This design ensures you enjoy an abundance of natural light and uninterrupted views. At ZIIISUN, we offer a diverse range of RAL color options, finishes, frame styles, and custom sizes to craft a unique, tailor-made solution for your specific project needs.

Q1: Are there any issues with the glass inside? Does it get steamy or foggy?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is professionally crafted to prevent steam or fog between the double glass.
Q2: Do all these doors and windows come with frames for wall mounting?
A:Yes, all the doors and windows include frames. Installing them on walls is perfectly fine.
Q3: What if the glass breaks for no apparent reason? I'm worried the rest will also break.
The glass will only break due to impact force; it won’t break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is highly recommended to use 5mm double glass because:
Sliding doors look unattractive with single glass. There is a wide space for glass, and using single glass would require excessive silicone filling.
5mm double glass is safer than 6mm single glass.
5mm double glass offers better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but only on one side. The other side must use glass silicone because double rubber isn't strong enough and is more prone to falling off compared to glass silicone.
