Engineered Security for Contemporary High-Rise Living
As a leading Chinese exporter in the door and window sector, DERCHI delivers precision-engineered, customized apartment entry doors tailored to stringent global building codes, anti-burglary standards, and residential acoustic criteria.
Pioneering High-Performance Multi-Family Architectural Entry Solutions
As an industry-leading manufacturer and trusted brand recognized by Xinhua News Agency, DERCHI Doors and Windows (Guangdong Dejiyoupin Doors and Windows Co., Ltd.) specializes in bespoke security doors engineered for apartment corridors, residential complexes, and luxury penthouses.
Urban apartment units demand superior Sound Transmission Class (STC) soundproofing, certified fire containment ratings, and advanced anti-pry resistance without compromising on contemporary architectural aesthetics. By integrating industrial automation with aerospace-grade alloy treatments, DERCHI solves multi-family safety, privacy, and thermal efficiency challenges at scale.
High-Precision Security Architecture Engineered to Protect
Modern apartment entrance doors require multi-layered engineering defense. DERCHI pairs patented structural reinforcement with advanced acoustic resonance barriers and biometric access integration.
Proprietary Four-Side Six-Point Locking Invention
Burglary deterrence in multi-tenant environments requires perimeter locking that withstands mechanical levering and hydraulic spreaders. DERCHI holds over 100 national invention patents, featuring our exclusive Four-Side Six-Point Lock mechanism.
This system engages continuous hardened alloy bolts across the top, hinge-side, threshold, and strike jamb simultaneously. Combined with heavy-gauge galvannealed steel reinforcement subframes and internal interlocking multi-rib structures, DERCHI security doors resist forced entry attempts for extended durations exceeding international RC3 and RC4 performance standards.
- Reinforced Internal Core: High-density aviation aluminum honeycomb combined with rockwool dampening.
- Dual-Seal Acoustic Gaskets: Specialized EPDM perimeter compression seals absorbing up to 45dB of corridor noise.
- Smart IoT Integration: Direct support for 3D facial recognition, biometric finger-vein scanner, and building concierge automation.
Anti-Drill & Anti-Pry Armor
Solid manganese armor plates safeguard the lock body against high-speed drill bits, thermal torches, and concentrated impact attacks common in residential burglaries.

View Product DetailsKey Factors in Selecting an Apartment Security Door Manufacturer
Specifying entrance doors for high-density multi-family developments requires balancing building life safety, acoustic isolation, and property longevity.
1. Building Code & Fire Egress
Apartment entryways form the primary life safety egress barrier. Doors must feature certified panic exit functionality, self-closing mechanisms, and documented fire containment ratings ranging from 30 to 120 minutes depending on jurisdiction.
2. STC Acoustic Isolation
Corridor noise pollution directly impacts tenant retention. Look for manufacturers utilizing multi-layer composite insulation, drop-down automatic acoustic threshold bottom seals, and dual continuous rubber gaskets achieving STC 35 to 45.
3. Bulk Project Customization
High-rise projects require uniform facade appearance alongside customized hardware options. Partnering directly with an OEM/ODM factory enables synchronized master key systems, custom veneer claddings, and tailored structural jamb sizes.
