Guangdong Dejiyoupin Doors & Windows (DERCHI Brand)

Recognized as one of China's Top 10 architectural door and window enterprises, Guangdong Dejiyoupin Doors and Windows Co., Ltd. operates a high-precision manufacturing campus in Foshan, Guangdong. Over 25 years of specialized metallurgical and fenestration engineering have positioned our organization as the premier OEM/ODM supplier for high-spec aluminum swing doors, grand pivot entrances, and curtain wall subsystems.

We solve the critical vulnerabilities faced by international developers: thermal deflection under scorching desert climates (UAE, Saudi Arabia, Qatar), cyclic wind-load fatigue in coastal typhoon zones (Florida, Caribbean, Philippines), and strict acoustic damping thresholds for hospitality and healthcare projects across Europe and North America.

Technical Comparison: Architectural-Grade vs. Generic Swing Doors

When procuring aluminum swing doors from China, technical discrepancies in alloy purity, thermal-break formulation, and gasket extrusion dictate whether a door lasts 30 years or fails within two seasons.

Future Procurement & Architectural Engineering Trends

Global architectural demands for aluminum swing doors are moving beyond basic closure systems into high-performance structural envelopes, carbon accounting, and seamless automation.

Quality Assurance

Step-by-Step Factory Audit & Supplier Verification Guide

Follow this standardized B2B verification checklist to inspect Chinese aluminum swing door fabricators before issuing letters of credit (LC) or telegraphic transfers (TT).

Phase 01

Extrusion Metallurgy & MTC Audit

Request original Mill Test Certificates (MTC) verifying primary alloy composition (Al-Mg-Si). Confirm tensile strength exceeds 205 MPa and yield strength surpasses 180 MPa. Reject suppliers using secondary melted remelt ingots which cause profile bubbling during anodizing and severe structural brittleness.

Phase 02

Corner Joint & Crimping Tolerances

Inspect corner joint fabrication. High-end swing doors must utilize CNC corner-crimping machines with structural aluminum corner keys and twin-component polyurethane corner injection glue (e.g., German Weiss Cosmofen). Ensure corner joints are water-tight and show zero stepped misalignment.

Phase 03

Surface Coating Film Thickness (DFT)

Deploy an ultrasonic dry film thickness gauge. Hard-anodized architectural profiles must demonstrate ≥ 20-25μm thickness (Class 1). For fluorocarbon PVDF powder coating, verify 3-coat finishes exceed 35μm with mandatory cross-hatch adhesion testing (ASTM D3359) achieving Class 5B.

Phase 04

Glass Cavity & Gasket Hermetic Seals

Verify that insulated glass units (IGU) feature warm-edge composite spacers (e.g., Technoform or Swisspacer) with continuous dual-seal polysulfide/silicone barriers. Inspect EPDM vulcanized molded corner gaskets to eliminate air whistling and water capillary action under driving rain conditions.

Procurement Knowledge Base

Frequently Asked Questions by Global Buyers

Get direct, engineering-backed answers addressing the most common friction points in sourcing custom architectural aluminum swing doors from China.

What minimum aluminum profile wall thickness should be specified for exterior swing doors?
For heavy-duty exterior swing and entrance doors subjected to high wind pressures and frequent cyclic operation, international building codes (including North American AAMA/WDMA and European EN 14351) recommend a minimum primary structural wall thickness of 2.0mm. For oversized entrance doors exceeding 2.8 meters in height, we engineer 2.5mm to 3.0mm profiles with internal reinforcing ribs to ensure zero diagonal sashing or frame distortion under continuous wind and hinge loading.
Why is Polyamide PA66 GF25 superior to PVC thermal break strips in desert and coastal regions?
Polyamide PA66 reinforced with 25% glass fiber exhibits a coefficient of linear thermal expansion (2.8 x 10^-5 K^-1) virtually identical to that of aluminum alloy (2.3 x 10^-5 K^-1). This prevents shear delamination, structural bowing, and air leakage when exterior profiles reach 80°C under Gulf sun while interior profiles are cooled to 22°C. In contrast, cheap PVC strips possess three times higher expansion rates, causing delamination, loss of watertightness, and profile warping within 18 to 24 months.
What surface treatment is required for beachfront villas and high-salinity coastal environments?
For ISO 12944 C5-M marine environments (such as Palm Jumeirah in Dubai, Miami coastal strips, or Sydney Harbour), we specify either Qualicoat Class 3 / AAMA 2605 certified PVDF fluorocarbon coatings (70% Kynar 500 resin base) or Qualanod certified hard anodizing with a minimum film thickness of 25 microns (±2μm). These finishes undergo 4,000-hour neutral salt spray (NSS) and accelerated QUV exposure tests with zero blistering, flaking, or significant color shift (ΔE ≤ 5.0).
How are heavy swing door panels protected against sag during transit and long-term operation?
Long-term anti-sag performance relies on diagonal "heel-and-toe" glass blocking techniques combined with heavy-duty structural hardware. Glass units are packed with high-durometer EPDM setting blocks positioned diagonally opposite the lower hinge, transferring glass weight directly into the bottom pivot. For panels weighing 150kg to 450kg, we integrate German-engineered concealed 3D adjustable continuous gear hinges or heavy oil-bath floor springs rated for half a million operating cycles.
What documentation and test reports do you provide to support consultant submittals?
Every DERCHI project consignment is accompanied by a complete technical submittal binder containing: stamped engineering CAD shop drawings, structural wind load and thermal finite element analysis (FEA) calculations, Mill Test Certificates (MTC) for alloy compositions, accredited third-party test reports for air permeability (ASTM E283), water tightness (ASTM E331), structural adequacy (ASTM E330), and acoustic attenuation (ASTM E90), alongside warranty certificates up to 10-15 years.
How are oversized pre-glazed aluminum swing doors packaged for oceanic container shipment?
Export shipping integrity is critical. All door panels and subframes receive a 3-layer protection protocol: non-staining surface protective film, heavy multi-layer bubble wrap, and full encapsulation within ISPM-15 compliant heat-treated fumigated plywood crates with internal foam cushioning. Doors are crated vertically on steel A-frame transit cradles with moisture-absorbing silica gel desiccants to prevent container condensation damage and salt corrosion across 30 to 45-day sea freight transits.
