Product Description

Anodized Folding Door Frames

1. Process: The Core Process of Anodizing Technology

Anodizing is an electrochemical process that forms a dense oxide film on the aluminum surface.

The core process includes:

Pretreatment:

Degreasing: Use an alkaline or acidic solution to remove oil and dirt from the aluminum surface, ensuring uniform adhesion of the oxide film.

Alkali Etching: Use a sodium hydroxide solution to etch the aluminum surface, removing machining marks and improving surface smoothness.

Acid Cleaning: Neutralize residual alkaline solution to prevent white spots on the oxide film.

Anodizing: The aluminum material serves as the anode and is placed in a sulfuric acid or chromic acid electrolyte. A direct current is applied to form an oxide film with a thickness of 5-30μm.

The oxide film has a porous honeycomb structure with a porosity of 30%-40%, providing a foundation for subsequent coloring.

Coloring:

Electrolytic Coloring: Use a metal salt solution (such as tin or nickel salts) to fill the pores of the oxide film, creating a stable color such as bronze or black. Dye Coloring: Organic dyes penetrate the pores to achieve vibrant colors like red and blue, but weather resistance is slightly inferior to electrolytic coloring.

Pore Sealing: Boiling water or steam is used to seal the pores of the oxide film, preventing contaminants from entering and improving corrosion resistance.

Data Support: Anodized aluminum can achieve a surface hardness of HV 400-600 (close to the hardness of sapphire), three times that of ordinary aluminum; its salt spray resistance is increased to 1,000-5,000 hours (compared to 200-500 hours for ordinary aluminum).

2. Material Advantages of Aluminum Doors: Synergistic Effect of Aluminum and Oxide Film

Lightweight and High Strength:

Aluminum has a density of only 2.7 g/cm³, about one-third that of steel. However, the oxide film formed by anodizing can increase its surface hardness by 3-5 times, significantly enhancing scratch resistance. Weather and Corrosion Resistance:

The oxide film isolates the aluminum from air. In coastal environments with high salt spray, the 10-year corrosion rate is ≤0.01mm/year, significantly lower than the 0.5mm/year for untreated aluminum.

Environmental Protection and Recyclability:

The anodizing process uses no heavy metals and complies with EU RoHS standards. The aluminum recycling rate is as high as 95%, and the energy consumption is only 5% of that of virgin aluminum.

Aesthetic Diversity:

Electrolytic coloring allows for metallic finishes such as bronze and champagne, meeting the color consistency requirements of high-end architecture (color difference ΔE ≤ 1.5).

3. Data-Driven Features: A Double Breakthrough in Performance and Design

Dimensional Stability:

The anodized aluminum profile has a thermal expansion coefficient of 23.5×10⁻⁶/K, 40% lower than PVC. At a temperature difference of ±40°C, the folding door frame deformation is ≤0.5mm/m, ensuring long-term, smooth operation. Sound Insulation:

When used with insulating glass (e.g., a 5+12A+5mm configuration), Aluminum Folding Doors achieve a total sound insulation of 35-40 decibels, reducing traffic noise by 25-30 decibels, meeting residential sleep requirements (≤30 decibels).

Airtightness:

Utilizing a multi-layer sealing strip design, the door achieves GB/T 7106 standard Level 8 (the highest level) airtightness. Air leakage at a pressure differential of 10 Pa is ≤0.3 m³/(m·h), a 70% reduction compared to conventional doors.

Load Capacity:

With anodized aluminum profiles with a wall thickness of ≥2.0 mm and a high-strength pulley system, the door can withstand a load of 150 kg per leaf, meeting the requirements of folding door designs up to 3 m wide.

4. Application Scenarios for Custom Aluminium Doors

High-end Residential:

In villas and large apartments, anodized folding door frames can be paired with Low-E glass to achieve a thermal insulation coefficient (K) of ≤1.8 W/(m²·K), saving 40% energy compared to ordinary aluminum doors. Available in high-end colors such as champagne and black, these doors enhance the building's aesthetic appeal.

Commercial Buildings:

Shopping malls, hotels, and other venues utilize anodized folding door frames, enabling single-leaf door widths up to 1.2m and over 80% openable area, meeting high-traffic traffic demands. Combined with an electric sensor system, these doors can be opened and closed over 10,000 times daily without any issues.

Public Facilities:

Hospitals and schools utilize antibacterial-coated aluminum profiles and fire-resistant glass, achieving a fire resistance of ≥90 minutes, in compliance with the GB 50016 fire protection standard. The residual bacterial rate on the oxide film surface is ≤0.1%, meeting hygiene requirements.

Extreme Environments:

In coastal typhoon-prone areas (such as Australia's Gold Coast), anodized folding door frames are BAL-40 certified and can withstand 60m/s wind speeds (a force 17 typhoon) for one hour, with only 32mm of door leaf deformation, far below the standard requirement of 50mm.
