Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) represents China's gold-standard in high-performance aluminum architectural fenestration.

Situated in the heart of China's industrial aluminum fabrication hub (Nanhai District, Foshan), our manufacturing campus houses automated CNC extrusion machining centers, multi-axis milling technology, vacuum wood-grain transfer lines, and robotized fluorocarbon PVDF powder coating operations. We eliminate intermediaries by offering direct factory engineering support to developers across the United States, Canada, Australia, and the United Kingdom.

Unlike standard fabricators, DERCHI operates rigorous in-house physical laboratories. Every door series undergoes cyclic loading tests, salt spray corrosion tests exceeding 1,000 hours, and air-water tightness evaluations reaching AS 2047 N6 standard—the highest achievable performance bracket for extreme hurricane and cyclonic regions.

Frequently Asked Questions on Aluminium Main Door Procurement

Everything project managers, architects, and quantity surveyors must verify when importing custom aluminum entry doors directly from China.

What aluminum alloy grade and profile wall thickness do you specify for exterior main doors?
We exclusively utilize 6063-T6 or 6061-T6 architectural grade virgin aluminum alloy extrusions. For primary entrance systems and heavy pivot doors, our profile wall thicknesses range from 2.0mm to 3.0mm (conforming to AAMA/WDMA/CSA 101/I.S.2/A440 requirements). This heavy-gauge design ensures structural integrity, resists deflection under extreme wind loads, and prevents panel sagging over decades of commercial or residential use.
How do your aluminum entry systems prevent thermal bridging and condensation in cold climates?
Our cold-climate main doors incorporate multi-cavity thermal-break architecture using Technoform PA66 GF25 polyamide insulation strips that mechanically isolate the exterior and interior aluminum extrusions. In combination with insulated panel cores (polyurethane or high-density rockwool) and dual/triple tempered Low-E glazed units filled with 90% argon gas, our doors prevent cold bridging, reduce thermal transfer, and maintain comfortable interior surface temperatures even in Canadian, North American, or Northern European winters.
What international testing certifications and compliance documents can you provide for building permits?
Our products hold comprehensive international testing documentation: Australia AS 2047 (certified to N6 cyclone rating), AS 1288 architectural glass standards, European CE certification (EN 14351-1), ISO 9001 quality management, and UL fire-rated door assemblies. For every project, our engineering department provides official test laboratory certificates, thermal simulation calculations, and stamped shop drawings to support quick approval with local building code authorities.
What surface treatments are offered to resist oceanfront salt spray and extreme UV radiation?
We offer AkzoNobel Interpon D2525 powder coating (AAMA 2604 / AAMA 2605 compliant), 3-coat Kynar 500 fluorocarbon (PVDF) finishes, and 25-micron architectural anodizing. For coastal applications within 500 meters of seawater (such as Florida, California, Hawaii, or Australia), our marine-grade PVDF coating passes 3,000 hours of continuous salt-spray testing without blistering, chalking, or color fading, backed by a 15-to-25-year factory finish warranty.
How does the factory manage overseas packaging to ensure damage-free international arrival?
Every door leaf and pre-hung subframe undergoes a rigorous 5-layer export packaging protocol: 1) Protective PE film on all visible profiles; 2) High-density EPE pearl foam wrapping; 3) Corner collision protectors; 4) Moisture-absorbing desiccant packs; and 5) Fully enclosed, fumigation-free solid plywood export crates reinforced with external steel strapping and forklift skids. Over 99.8% of our shipments arrive at job sites in pristine condition.
Can you manufacture prehung systems directly from our custom architectural drawings and rough openings?
Yes, 100% bespoke manufacturing is our core strength. You can submit rough opening dimensions in inches or millimeters, along with architectural elevation drawings. Our design department will draft detailed CAD shop drawings with section details, floor sill transitions, hardware locations, and anchor points for your written approval before any profile is cut. We also factory-prehang the door to verify tolerances, latch alignment, and weatherseal compression before crating.
