Internal Aluminium Bifold Doors

  An internal aluminium bifold door is an indoor partition door composed of multiple narrow door panels (leaves) hinged to each other, with an aluminium alloy frame as the main structural support. When opened, the door panels fold sequentially towards one side (or both sides) along the track; when closed, they form a flat, sealed whole. It is designed to flexibly divide or connect indoor spaces, without occupying extra space during opening

Key structural components:

1.Aluminium alloy frame: Lightweight, high-strength and deformation-resistant aluminium profiles, which can be surface-treated (powder coating, anodizing, wood grain transfer) to match indoor decoration styles.

2.Door panel filling: Common options include glass (tempered glass, frosted glass, laminated glass) or solid panels (wooden veneer, PVC board). Glass filling is more popular for its light transmission and visual openness.

3.Hinges & tracks: Special folding hinges connect adjacent door panels, and bottom/top tracks guide the door panels to fold and slide smoothly. High-quality tracks are designed to be silent and wear-resistant.

4.Hardware accessories: Equipped with door locks, handles and limiters, ensuring stable closing and safe use.

Advantages of Internal Aluminium Bifold Door 

1.Space-saving design

Unlike swing doors that need to reserve a "door swing space", internal aluminium bifold doors fold to the side when opened, which takes up less than 10% of the space occupied by traditional swing doors. This is especially suitable for small spaces such as apartments, small offices or walk-in closets.

2.Flexible space division It can realize two states: "full closure" and "full opening". When closed, it isolates independent spaces (e.g., separating the living room from the dining room, or dividing a study from a bedroom) to meet the needs of privacy or noise reduction; when fully opened, the door panels are folded to the side, making two spaces connected into a whole, which is ideal for family gatherings, party layouts or expanding the visual sense of space.

3.Lightweight & easy to operate

The aluminium alloy frame is light in weight but high in rigidity. Even if there are multiple door panels, it can be pushed and pulled with one hand smoothly. The silent track design avoids the noise of door opening and closing, which is friendly to families with the elderly, children or people who need a quiet environment.

4.Strong durability & low maintenance

Aluminium alloy has good corrosion resistance and is not easy to warp, crack or rust in indoor environments. The surface is smooth and not easy to accumulate dust. Daily maintenance only needs to wipe the frame and glass with a damp cloth; the track can be kept smooth by occasionally cleaning the accumulated debris.

5.Good decorative & adaptable

The frame can be customized into various colors (white, black, grey, wood grain, etc.) to match different interior styles (modern minimalist, Nordic, industrial style, etc.). The door panel can be matched with transparent glass to maintain light transmission between spaces, frosted glass to ensure privacy, or solid panels to enhance the partition effect. It can be installed in door openings of different widths by adjusting the number of door panels.

6.Good sealing performance

When closed, the door panels are tightly fitted with each other and the door frame, which can effectively block the spread of indoor noise (e.g., isolating the noise of the kitchen from the living room) and prevent the loss of indoor temperature, helping to improve the comfort of the space.
