Guangdong Dejiyoupin Doors and Windows Co., Ltd.
How commercial contractors, developers, and global importers navigate thermal performance, extreme weather durability, anti-burglary multi-point hardware, and direct manufacturing efficiencies.
25+ Years of Structural Innovation
Engineered For Zero DeflectionAS2047 N6 · CE · ISO9001 · UL
From coastal salt spray resistance to smart IoT multi-point integration, discover why Tier-1 builders prioritize precision aluminum alloy entry doors.
When sourcing an aluminum alloy entry door for modern developments, selecting the correct internal core, extrusion profile, and structural hinge geometry is essential to eliminate warping, prevent thermal bridging, and achieve high burglar resistance.
Thermal Break System Polyamide PA66 thermal barriers mitigate heat convection, preventing leaf deflection and air leaks across fluctuating environments.
RC3 / RC4 Security Reinforced multi-point locking gear paired with an internal steel core delivers certified RC3 forced-entry protection for luxury properties.
Cast Solid Series Monolithic 8mm-12mm solid cast alloy facings eliminate external skin delamination, providing lifelong elegance in coastal and desert zones.
Panoramic Pivot Architectural glass panels set inside heavy-duty aluminum extrusions, delivering modern spatial openness with high soundproofing.
Global developers and project general contractors are moving past simple aesthetics. Procurement criteria for an aluminum alloy entry door have shifted from basic closure functions toward rigorous life-cycle cost modeling, integrated smart biometrics, and multi-climate structural certifications.
Reduced Maintenance Over 30 Years
Developers are eliminating high-maintenance timber and easily rusted low-gauge carbon steel doors, turning to aluminum alloy entry doors for their near-zero maintenance footprint.
Smart Home & Hotel Access Control
Modern commercial and residential procurement specifications require seamless concealment of motorized digital hardware within the aluminum alloy profile structure.
Net-Zero Energy Standards
Global building energy codes mandate stricter insulation limits. Non-thermal aluminum frames are being phased out in favor of polyamide structural breaks.
Floor-to-Ceiling Grand Entrances
Architects are prioritizing grand door formats up to 4 meters high and 2 meters wide, demanding higher aluminum tensile strength and precision balancing.
A trusted manufacturing partner for worldwide distributors, real estate developers, and commercial contractors seeking high-grade aluminum alloy entry door systems.
Ranked among the Top 10 leading door and window brands in China, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (operating the internationally recognized DERCHI brand) brings over 25 years of specialized extrusion manufacturing, surface processing, and hardware engineering to global supply chains.
Our expansive 180,000 square meter industrial facility in Foshan, Guangdong houses advanced European CNC profile processing lines, automated electrostatic fluorocarbon coating lines, and precision assembly lines. We manage the entire fabrication chain: from raw aluminum billet quality analysis to final export crating.
Over 30 appearance and technical utility patents ensure every aluminum alloy entry door leaves our production floor compliant with the strictest architectural specifications.
Consolidate your entire door and window schedule in unified factory shipments.
Meeting international building codes requires verified laboratory testing. Our aluminum alloy entry doors are certified to support smooth site sign-offs and municipal building approvals.
Export documentation includes mill test certificates, acoustic decoupling reports, packing lists, and conformity certificates for local pre-shipment inspections (including SONCAP, KEBS PVoC, and SASO).
A structured engineering process guarantees your aluminum alloy entry door arrives built to spec, pre-fitted, and secure against transit damage.
We review your window and door schedules, architectural sections, and performance criteria to propose the ideal structural profile thickness, glass build, and security package.
Every rough opening is converted into comprehensive 2D/3D CAD shop drawings detailing profile sections, anchor locations, sub-sill drainage, and hardware mortises.
Primary extrusion profiles are milled on computer-controlled 5-axis machining centers. Corners are hydraulically crimped with injected two-part structural epoxy corner cleats.
Door slabs and master frames are wrapped in peelable surface protection films, padded with closed-cell EPE foam, and encased in fully enclosed fumigated plywood crates.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. supplies detailed installation manuals, video guides, and video-call technical support for your onsite glazing and installation teams.
