What are Folding Doors / Bifold Doors?
A folding door comprises several panels the user can fold or unfold to open or close the door. The door is also dubbed ‘bi-fold door’ or ‘Concertina door’ in relevance to the musical instrument. However, naming it a Bi-fold door is inaccurate as it usually encompasses 2, 4, or more panels. The panels move along a track with the aid of rollers, and the user can pull them back to one side using a knob.From room separators to kitchen entrances, bi-fold doors are undoubtedly handy. They are suitable for separating any two spaces and can extend considerably, thus gaining an advantage over traditional doors concerning accessibility and visibility. This article will help you know more about folding doors and see if they suit your place. Now, let’s get started with the materials, shall we?
What Is an Aluminum Folding Door
Aluminum folding doors are made of aluminum thermal break profiles, perfectly integrating large areas of glass with extremely narrow vision frames. The entire wall can be fully opened to achieve a dynamic transformation between indoor and outdoor spaces. Moreover, it integrates the advantages of aluminum alloy such as heat insulation, durability, corrosion resistance and wear resistance, with the spatial advantages of the folding structure design. With features such as good lighting, space-saving design, a wide field of vision, and strong sealing, it is widely used in residential and commercial settings.Which Systems Are Aluminum Folding Door Profiles Compatible With
Aluminum folding door profiles are the core foundation of the folding door systems, featuring extremely strong compatibility and being flexibly adapted to different functional requirements and usage scenarios. The flexibility of its structure, adjustable load-bearing capacity and the space for customised design enable it to seamlessly integrate with various folding systems. So, in which systems are aluminum folding door profiles specifically suitable? Based on our previous project practices and industry experience statistics, we have sorted out the following five mainstream compatible systems:
1.Top-Hung Folding System
This system suspends the entire weight of the door panels on the top track, imposing extreme demands on the vertical bending strength and anti-deformation capacity of the profiles. Suitable profiles require extremely high structural strength and a precise top pulley groove design, which can effectively support the weight of the door body and ensure smooth pushing and pulling without jamming when suspended.
2.Bottom-Rolling Folding System
When the load is transferred to the bottom track, the design core of the profile focuses on stability at the bottom and guidance accuracy. The bottom of the profiles must be designed with a sturdy roller cavity that fits precisely, combined with the ground track. The weight of the door body is evenly distributed along the ground track, while enhancing the wear resistance of the profiles to meet the usage requirements of large-span and heavy-duty folding doors.
3.Combined Load Folding System
The weight of this system is shared by the top and bottom, making it one of the most stable and load-bearing systems. The profiles need to meet the dual structural requirements of both the top suspension and the bottom guidance. By thickening the force-bearing wall thickness and optimising the cavity layout, synchronous load-bearing at the top and bottom is achieved, significantly enhancing the system stability. Designed specifically for extra-large and extra-heavy door panels and scenarios with high wind pressure resistance requirements.
4.Multi-Panel Folding System
When multiple door panels are continuously folded, the accuracy of the profile connections becomes crucial. The profile structure of each door panel must maintain a consistent height, and the profile cross-section at the hinge connection must be specially strengthened to ensure uniform force and prevent deformation when multiple door panels are linked together. Achieve synchronous, uniform and smooth opening and closing of multiple door panels during the folding process.
5.Minimal / Hidden Hardware System
Pursuing the ultimate minimalist visual effect and hiding the hardware, such as hinges and locks, as much as possible. The profile should adopt an extremely narrow frame design, with an embedded cavity reserved for hidden hardware inside and no exposed components on the outside. The profile surface needs fine treatment to ensure uniformity in the overall visual effect after folding. While ensuring structural strength, the hardware components create a neat, beautiful visual effect.
Aluminum folding door profiles are not limited to a single folding system. Their adaptability depends on structural design, load distribution, and hardware integration, making them suitable for a wide range of folding door and window systems.

In the field of Aluminum folding doors and windows, Shenghai Aluminum, with its professional R&D and customisation capabilities of aluminum profiles, has successfully served customers in many countries and regions around the world and accumulated rich practical experience.
Previously, we provided folding door profiles for Bahrain Door and Window Systems Company. In response to the cooperation requirements, we focused on the local high-temperature and dry climate characteristics and the core demands of buildings for heat insulation and durability, and specially developed aluminum thermal break profiles suitable for their folding door systems. These profiles adopted PA66GF25 nylon thermal break strips and a multi-chamber structure design, effectively blocking heat conduction. At the same time, by enhancing the wall thickness of the profiles and precisely processing the pulley grooves, seamless integration with the customer's existing hardware system is achieved. The load-bearing stability and smooth opening and closing of the product far exceed industry standards, perfectly meeting the strict requirements of the Bahrain market for door and window heat insulation and durability.
In the project in Fiji, we developed innovative mosquito-proof aluminum folding sliding window profiles in response to the special scenarios of numerous mosquitoes and high humidity on the local tropical islands. By reserving a customised mosquito-proof mesh installation cavity in the profile structure, the mosquito-proof function and the folding and sliding structure are perfectly integrated. It neither affects the spatial folding flexibility of doors and Windows nor effectively prevents mosquitoes from invading. Meanwhile, the powder coating on the profiles' surfaces enhances their resistance to salt spray corrosion and moisture-proofing, making them suitable for high-humidity, high-salt-spray environments on islands.
These successful cases that span different climates and demands jointly prove the core value of Shenghai Aluminum: what we sell is not only profiles, but also systematic problem-solving capabilities based on profound scene insights.
