The Steel Exterior Front Door is an exterior door system with a core structure made of high-strength steel, designed specifically for long-term use in both indoor and outdoor environments, balancing security, protection, and overall architectural aesthetics. This type of door features a 95mm thick door panel structure, combined with a 50mm back frame and a 100mm trim system, forming a stable overall load-bearing frame. This design significantly differentiates it from ordinary entrance doors in terms of impact resistance, anti-pry capabilities, and sealing performance. Additionally, the door is filled with aerospace-grade polyurethane material, which enhances overall strength while also providing sound insulation, thermal insulation, and environmental adaptability.

This series supports customization in a variety of colors and surface textures, including sophisticated gray tones, brushed metal finishes, delicate woven textures, and modern matte effects.  These options allow for flexible selection based on project requirements and overall design style, achieving both visual consistency and personalized expression.

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. Stable and Reliable Structure

The Steel Exterior Front Door features an integrated design of steel door frame and door leaf, with a door leaf thickness of 95mm, which is approximately 20% stronger in overall bending resistance compared to conventional 70-80mm structures. Combined with a 50mm back frame width and 100mm trim structure, it forms a frame system that evenly distributes loads in the door opening's stress-bearing area.

2. Outstanding Anti-Prying Performance

The door body utilizes an interlocking anti-pry steel structure, coupled with a 40×388 stainless steel 9-bolt lock body, creating multi-point simultaneous locking when closed. Test data shows that the multi-point locking structure distributes single-point force in multiple directions, increasing anti-pry strength by more than 35%, effectively reducing the risk of damage to the door structure from forced entry.

3. Strong Corrosion Resistance

The steel surface of the Steel Exterior Front Door undergoes a multi-layer protective treatment system, allowing it to withstand over 500 hours of salt spray testing without significant corrosion. This corrosion resistance is suitable for high-humidity, frequently changing temperature, or coastal environments, helping to extend the door's lifespan and reduce structural and aesthetic problems caused by surface rust.

4. Excellent Sound Insulation

The door leaf is filled with aerospace-grade polyurethane material, whose density and closed-cell structure create a stable cushioning layer inside the door. This filling structure reduces external noise transmission by approximately 25-30 decibels and effectively reduces heat exchange in environments with alternating hot and cold temperatures, giving the door practical environmental control capabilities in addition to security.

5. Flexible and Diverse Customization

The Steel Exterior Front Door supports systematic customization of door panel finishes, colors, frame structure, and opening methods. Surface finishes can be selected according to design requirements, including small square patterns, linear fabric patterns, or matte dark colors, meeting the needs of different architectural proportions.

1. Ground Floor of High-Rise Buildings

In the ground floor area of high-rise buildings, the Steel Exterior Front Door can withstand the pressure caused by frequent pedestrian traffic and changing external environments. The 95mm door leaf structure and multi-point locking system maintain stability under high-frequency daily use, reducing the risk of door sagging or lock misalignment, and contributing to consistent and safe long-term use.

2. Urban Street-Facing Buildings

Street-facing buildings are constantly exposed to wind, sand, rain, and air pollution, requiring high weather resistance from the doors. This door, through corrosion-resistant steel and a stable coating system, maintains surface integrity under continuous climate changes, helping to reduce maintenance frequency and preserve the overall visual effect of the building facade.

3. High-End Renovation Projects

In existing building upgrade and renovation projects, the Steel Exterior Front Door can be customized in size and finish to match existing door openings. By adjusting the door frame structure and surface design, the new door achieves simultaneous improvements in safety performance and aesthetic quality without damaging the original building structure.

4. Independent Office Entrances

Independent office entrances typically require a balance between security and image. This door, with its simple lines and dark metal texture design, combined with a stable locking system, ensures the security of the entrance while creating a professional and understated appearance, suitable for long-term use in office building entrances.

5. Customized Architectural Projects

In customized projects that emphasize architectural individuality, the Steel Exterior Front Door can be integrated as part of the overall facade system. Through adjustments in color, texture, and door frame proportions, the door blends seamlessly with the building materials while maintaining the reliable performance foundation provided by the standardized steel structure.

Q: Is the Steel Exterior Front Door suitable for long-term outdoor use?

A: The door body was designed with outdoor use in mind, incorporating appropriate structural and material configurations. The steel surface is treated with a corrosion-resistant system, demonstrating stable performance in salt spray tests and humid environment simulations. Proper installation and regular basic cleaning are sufficient for long-term outdoor use, requiring no frequent maintenance.

Q: Will increased door thickness affect smooth opening?

A: While the door panel thickness is increased to 95mm, it is equipped with a 3D adjustable concealed hinge structure. This hinge allows for fine-tuning in multiple directions, ensuring smooth opening even with increased weight, avoiding resistance issues caused by the increased weight.

Q: Can the color and structure be customized according to project requirements?

A: The Steel Exterior Front Door supports systematic customization from the door panel finish to the door frame structure. The customization process is based on unified steel standards, ensuring that appearance changes do not affect the door's safety, protection, and performance, making it suitable for projects with specific design requirements.

Q: Is the multi-point locking system complicated to use in daily life?

A: The multi-point locking system operates the same way as a conventional door lock; no extra steps are required for opening and closing. The internal structure uses a synchronized linkage mechanism to achieve multi-point locking, enhancing safety performance without increasing complexity, making it suitable for long-term, high-frequency use.

Q: Is this door compatible with smart lock configurations?

A: The door lock body structure reserves standard installation space and is compatible with various smart lock models. By selecting the appropriate smart lock product, it is possible to combine electronic identification and mechanical protection without altering the door structure, meeting the needs of different projects.
