What Types Of Bi-Folding Doors Are There?

Bi-folding Doors are a popular door type, renowned for their space-saving design. They are used in many homes, commercial properties, and industrial settings. There are many types of double-fold doors, differing in the number of door panels, opening mechanism, power supply, and materials. The following mainly discusses double-fold doors made of different materials.

What is a Bi-folding Doors?

First, we need to understand what a double-fold door is. It typically consists of two or more door panels, upper and lower guide rails, guide wheels, a pivot, etc. To open, manually push the door panel to rotate and fold along the pivot, while simultaneously sliding the panel to the sides and folding it towards the door frame. This is the general opening method for double-fold doors. Of course, some special doors may have unique structures and opening mechanisms.

What are the types of Bi-folding Doors?

Based on material, double-fold doors generally come in these types: aluminum bi-folding doors, PVC double-fold doors, wooden double-fold doors, etc. Each material has its advantages; choose the appropriate type based on the specific application.

Aluminum Bi-folding Doors

Pressure Resistance and Security: High-quality aluminum bi-folding doors use thermally broken aluminum profiles as the door frame. This frame typically uses 6063 aluminum alloy profiles with a multi-cavity structure and reinforcing ribs, giving it excellent pressure resistance. It can maintain its shape even in strong winds, heavy rain, and ordinary impacts. Combined with tempered glass as the door panel, this also provides security.

Light Transmission and Aesthetics: Aluminum double-fold doors are generally paired with glass door panels. We can choose from tempered glass, insulated glass, coated glass, frosted glass, etc., all of which offer varying degrees of light transmission and have an elegant appearance, especially coated and frosted glass. Aluminum bi-folding doors are particularly suitable for sunny environments like balconies.

Durability: Durability is also a major advantage of aluminum-glass bi-folding doors. The aluminum profile door frame not only has strong tensile strength but also excellent corrosion resistance (thanks to its powder-coated surface treatment). Therefore, aluminum bi-folding doors will not corrode or deform even after many years of use.

Customizable Appearance: Bi-folding door frames are available in various cross-sectional shapes and colors, including common shapes such as U-shaped, square tube, H-shaped, L-shaped, and T-shaped. Surface treatments are available in numerous colors, including champagne, wood grain, black, silver-gray, and white. Powder coating offers over 2000 colors.

Environmentally Friendly: One of the advantages of aluminum profiles is their environmental friendliness. Even after decades of use, their recyclability can reach 90%, significantly reducing raw material usage and aligning with global environmental policies.

PVC Doors

Affordable Price: Compared to other materials, PVC folding doors offer excellent value for money. This allows you to purchase a high-quality double-fold door at a more affordable price, creating a comfortable and beautiful home.

Easy Installation: Due to its lightweight nature, PVC doors are relatively easy to install. Unlike metal and glass doors, installation only requires manual labor and does not require heavy machinery, saving costs.

Moisture Resistance: PVC doors are more moisture-resistant than metal and wooden doors, thanks to their naturally moisture-resistant materials. PVC doors are more suitable for humid environments, such as kitchens, bathrooms, and toilets.

Wooden Double-Fold Doors

Natural and Beautiful Appearance: Wooden double-fold doors have natural wood grain colors and a soft texture. Common wooden door styles tend to be classic, making them ideal for warm and inviting environments like homes.

Natural Wood Scent: Some wooden doors have a natural woody fragrance, creating a sense of being in nature and providing comfort.

Unique Grain Pattern: No two pieces of wood are exactly alike; therefore, the grain patterns of wooden doors are also different. Each part of a wooden door has a unique grain pattern, making it highly aesthetically pleasing.

Stainless Steel Doors

High Corrosion Resistance: Unlike aluminum alloys, stainless steel’s high corrosion resistance doesn’t rely on surface treatment. Even after wear, it maintains high corrosion resistance, which is arguably one of its greatest advantages.

High Strength: Its hardness is extremely high, far exceeding that of aluminum alloys, making it an ideal material for applications requiring strength. It is frequently seen in industrial and commercial settings.

Mirror-like surface: Its surface is very smooth, and its reflective effect is even comparable to a mirror. Due to its properties, its surface reflects light strongly and has a good gloss. Therefore, stainless steel doors are more suitable for people who like a metallic style.
