Product Description

Three-track Large Aluminum Alloy Sliding Folding Door

1. Material Advantages

The three-track large aluminum alloy sliding folding door uses high-strength aluminum alloy profiles as its core frame, combined with multi-layered hollow tempered glass and high-density sealing strips, forming a composite structure that combines strength and flexibility. The aluminum alloy profiles undergo anodizing or fluorocarbon spraying treatment, significantly improving surface corrosion resistance and enabling it to withstand high-salt spray environments in coastal areas or acid and alkali corrosion in industrial zones, with a service life of over 20 years.

The Double Glass Entry Aluminum Commercial Doors use inert gas between the hollow glass layers, combined with warm edge spacers, effectively reducing the heat transfer coefficient. Winter insulation performance is improved by 40%, and summer heat insulation efficiency is increased by 35%, significantly reducing air conditioning energy consumption. The three-track design allows for independent sliding of the three door panels. When open, the door panels can be completely folded to one side, achieving 100% space release and increasing the ventilation area by 50% compared to traditional double-track doors, meeting the needs of large-span openings. The door features adjustable stainless steel guide wheels embedded at the bottom, along with a top guide groove, ensuring smooth and noiseless door operation. Its wind pressure resistance meets national standard level 9, capable of withstanding force 12 winds.

2. Application Scenarios

Aluminum Commercial Doors are widely used in three types of scenarios:

Commercial Spaces: High-end hotel banquet halls and convention centers require frequent adjustments to their spatial layout. Three-track doors allow for rapid transitions between indoor and outdoor scenes. Equipped with an electric control system, they support remote control and intelligent sensor-based opening and closing, improving operational efficiency.

Industrial Sector: Logistics warehouses and cold chain workshops require doors that combine airtightness with rapid passage. Three-track doors utilize double-layer brush sealing strips and a bottom airbag sealing design, achieving an IP65 dustproof rating. Combined with a variable frequency opening and closing speed of 0.8-1.5 m/s, they meet the demands of high-frequency logistics operations.

Residential Renovation: For villa courtyards and balcony partitions, a balance between natural light and privacy is needed. Three-track doors can be made with Low-E coated or frosted glass, and the light transmittance can be controlled by adjusting the opening width of the door panels. Their minimalist frame design (minimum visible width of only 35mm) blends seamlessly with interior design styles.

3. Suitable Purchasing Groups

Three customer groups should prioritize this product:

High-end Real Estate Developers: When projects are positioned as luxury residences or commercial complexes, the energy-saving performance of three-track doors (whole window K-value ≤ 1.8W/㎡·K) can help obtain green building certification and enhance the project's premium value.

Industrial Facility Managers: Chemical and food processing companies have strict requirements for workshop environmental control. The sealing structure of three-track doors can effectively block the spread of odors, and their durability, capable of withstanding 3000 openings and closings per day, reduces maintenance costs.

Space Design Agencies: When renovating historical buildings or creative office spaces, the modular design of three-track doors supports custom non-standard sizes (maximum span up to 12 meters), and combined with a concealed hinge system, achieves a "frameless" visual effect.

4. Key Selection Points

When purchasing Aluminum Doors, pay close attention to these four core parameters:

Frame Specifications:High-quality aluminum doors use virgin aluminum ingots (grade 6063-T5) with a wall thickness ≥2.0mm. CNC precision machining ensures strong corner connections. Inferior products often use recycled aluminum (with a grayish surface) or thinned profiles (wall thickness <1.4mm), which are prone to deformation and leakage.

Glass Configuration:Confirm whether it is 3C certified tempered glass. A 15-20mm thick insulated glass layer is recommended. Argon filling further improves thermal insulation. Avoid single-pane glass or ordinary insulated glass (prone to condensation).

Hardware System:Carefully check the pulley system material (high-quality products use nylon + stainless steel bearings). The load-bearing capacity should be ≥150kg/pane. Inferior pulleys (plastic material) are noisy and prone to jamming. Hinges should be made of 304 stainless steel and have an opening/closing cycle capacity of over 100,000 times.

Sealing Performance: Suppliers are required to provide airtightness, watertightness, and wind pressure resistance test reports. The airtightness rating must meet national standard level 8 (leakage ≤ 1.5 m³/m·h under a pressure difference of 100 Pa), the watertightness rating ≥ 350 Pa, and the wind pressure resistance performance must pass a simulated level 12 wind pressure test.

In addition, a 5-year warranty is required, and the smoothness of door opening and closing (no jamming or abnormal noise) and sealing performance must be tested (an A4 sheet of paper should be unable to be pulled out when sandwiched in the door gap). For projects in coastal or highly polluted areas, drainage hole protective covers and dustproof brush strips can be added to further extend product lifespan.
