Front Entrance Aluminum Doors are customized door systems primarily constructed from aluminum alloy, designed for high-end residential and project-level building entrances. This product features an aluminum alloy door leaf and frame combination structure, with a door leaf thickness of 90mm. The front panel is available in 4mm, 6mm, or 8mm precision-machined aluminum panels, while the back panel is fitted with 1.0mm stainless steel or 2mm precision-machined aluminum panels, achieving a balance between structural stability and aesthetic consistency. The door body utilizes a standardized structural ratio with a 65mm back frame width and a 60mm door frame width, combined with a 45° angle splicing process to effectively control joint errors. The system incorporates a built-in 24-point stainless steel 16-bolt integrated lock body and supports various lock solutions and hardware customizations, ensuring safety, durability, and long-term stability. It is suitable for entrance scenarios requiring high structural precision and material reliability.

This product series supports a wide range of color and surface finish customizations, encompassing various metallic textures, fine sand textures, and composite coating effects. It can be flexibly selected according to different building facade styles and spatial design requirements, ensuring overall harmony, visual depth, and stable performance over the long term.

The hardware for this series supports diverse customization options, encompassing various handle shapes and material combinations. These options include minimalist linear designs and artistic elements, allowing for flexible matching based on door dimensions, user preferences, and spatial style. This ensures smooth operation and durability while enhancing the overall quality and design sophistication.

This series of doors can be customized with two smart fingerprint lock options, supporting multiple unlocking methods such as fingerprint recognition and password entry. The locks have a design that is consistent with the door's overall style, balancing ease of use with comprehensive security requirements.

1. Antioxidant Stability

The door body uses an aluminum alloy base material, with surface treatments including brushed black titanium and natural aluminum finishes. The oxide film thickness is controlled at ≥10μm, providing stable resistance against air oxidation and humidity corrosion in typical outdoor environments. Long-term environmental testing shows a surface color difference rate of less than ΔE 1.5, effectively delaying fading and surface aging, ensuring the consistent appearance and structural reliability of the front entrance aluminum doors over long-term use.

2. High-Strength Material

The door leaf main body is an aluminum alloy structure, with a total door leaf thickness of 90mm. The front and back panels use a combination of multi-specification metal plates. The aluminum alloy yield strength reaches ≥160MPa, reducing the weight by approximately 30%–35% compared to traditional wooden doors of the same size. This reduces the long-term load pressure on the hinges and door frame while maintaining rigidity, improving the overall system lifespan.

3. Precise Joining

The door frame and door leaf utilize a 45° precision joining structure, with a joining error controlled within ≤0.3mm. The flatness of the joint surface is significantly better than that of right-angle joining methods. This structure reduces the risk of joint displacement after installation, improves the overall stability of the door body, and provides a continuous force-bearing foundation for the subsequent sealing system, reducing loosening problems caused by uneven joints.

4. High-Efficiency Sealing

The door body is equipped with multiple sealing structures around its perimeter, combined with magnetic silent sealing strips and the door frame profile structure. In the closed state, the gap is controlled within ≤2mm. Under standard testing conditions, the door can achieve approximately 30dB of sound attenuation, effectively reducing the transmission of external environmental noise and providing more stable sound insulation performance for high-end entrance spaces.

5. Durable Lock Body

The system features a built-in 24-stainless steel 16-bolt integrated lock body. The number of lock bolts and their force distribution are more balanced, reducing the single-point lock bolt load pressure by approximately 40%. The lock body is made of stainless steel, with a fatigue resistance of over 100,000 opening cycles, maintaining stable locking accuracy and safety performance even in high-frequency use scenarios.

1. High-End Residential Entrances

In villa or high-end residential projects, aluminum entry doors can be precisely matched to the building facade proportions through custom sizing and color options. The 90mm door leaf thickness and multi-point locking system meet the comprehensive requirements for security, sound insulation, and long-term stable use, making them suitable for private residential projects with high demands on entrance quality.

2. Urban Apartment Projects

In mid-to-high-end apartment entrance applications, these front entrance aluminum doors can accommodate various installation methods, including outward or inward opening. The 65mm frame width facilitates connection with standard wall structures, reducing the need for on-site modifications, helping to control construction time and improve overall delivery consistency.

3. Commercial Building Entrances

Commercial space entrances require higher durability. The door's lock body and hinges are made of stainless steel, suitable for high-frequency daily use. The aluminum alloy material strikes a balance between strength and weight, helping to reduce the risk of door sagging, making it suitable for office buildings or display-oriented commercial entrances.

4. Customized Architectural Projects

In custom-built or design-oriented projects, the door supports style customization, hardware customization, and lock customization. Multiple surface treatment options can create a unified visual system with different building materials, meeting designers' requirements for material consistency and detailed expression.

5. Renovation and Remodeling Projects

In renovation scenarios of old building entrances, the relatively controllable weight of the aluminum alloy door reduces the load requirements on the original wall structure. The 60mm door frame width can flexibly cover the edges of the original door opening, reducing the extent of structural adjustments, improving renovation efficiency, and lowering construction risks.

1. Surface Cleaning

For daily cleaning, it is recommended to wipe the door surface with a neutral detergent and a soft cloth, avoiding acidic or strongly alkaline cleaning products. A reasonable cleaning frequency of 1-2 times per month will help maintain the integrity of the surface oxide layer and prevent discoloration caused by chemical corrosion.

2. Lock Body Maintenance

It is recommended to inspect the stainless steel lock body every 6-12 months, keeping the latch and moving parts clean. Avoid long-term accumulation of dust or particles to maintain the smooth operation and precise closing of the 24-point stainless steel integrated lock body under multi-point stress.

3. Hinge Inspection

For stainless steel concealed hinges, it is recommended to regularly check the condition of the fixing bolts to ensure that the door leaf maintains a stable opening trajectory under a thickness of 90mm. Adjustments can be made if necessary to prevent door misalignment or uneven stress after long-term use.

4. Seal Maintenance

The magnetic sealing strips and sealing structure should be inspected annually to ensure that their elasticity and fit are in normal condition. If aging or deformation is found, they should be replaced promptly to maintain a door gap control level of ≤2mm, ensuring sound insulation and sealing performance.

5. Surface Inspection

For black titanium brushed or natural aluminum surfaces, it is recommended to regularly check for scratches or abnormal wear. Minor scratches can be treated with professional care to prevent long-term neglect from damaging the surface protective layer and affecting overall durability.
