Standard solid aluminum doors transfer ambient external heat directly into conditioned interiors. DERCHI utilizes PA66 GF25 reinforced polyamide strips to isolate exterior and interior aluminum sections. This eliminates thermal bridging, achieves low U-values (< 1.4 W/m²K), and prevents condensation during severe temperature differentials.
Coastal and high-humidity environments degrade untreated timber and lower-grade metals within 24 months. Our exterior aluminum claddings undergo Qualicoat Class 2 PVDF fluorocarbon coatings and 25-micron hard anodization, passing 3,000-hour neutral salt-spray (NSS) testing without blistering, cracking, or pigment chalking.
Aluminum and interior solid woods expand and contract at different thermodynamic coefficients. DERCHI applies floating snap-lock composite clips. This mechanical fastening permits the outer aluminum skin to flex under intense solar radiation while the interior timber or core structure maintains zero structural warpage.
| Material Core Classification | Thermal U-Value Range | Wind Load Resistance | Maintenance Cycle | Coastal Salt Resistance | Structural Lifespan |

| Standard Steel Security Exterior Door | 2.20 - 3.20 W/m²K | 3.0 - 4.0 kPa | Periodic rust treatment / Painting | Severe corrosion risk at seams | 15 - 20 Years |
Ranked among China's Top 10 Door & Window Brands. Backed by our 180,000㎡ intelligent industrial base in Shishan Town, Foshan, delivering turnkey architectural export systems worldwide.
From primary alloy billet extrusion, thermal strip crimping, automated CNC corner crimping to electrostatic spraying—all phases occur in-house under strict ISO 9001 supervision.
Our 30+ engineering specialists generate bespoke shop drawings, section details, load-deflection calculations, and hardware mounting layouts for developer and architect sign-off before manufacturing.
Factory-direct assurance verified by testing bodies. DERCHI portals hold CE markers, ISO 9001 quality certificates, Australian AS 2047 cyclonic approvals, and certified UL fire-ratings.
Actionable intelligence for international developers, facade consultants, and general contractors structuring long-term residential and hospitality supply chains.
Luxury residential design has shifted from standard 2.1-meter leaves to floor-to-ceiling portals exceeding 3.5 to 5 meters in height. Global buyers are procuring reinforced aluminum-clad pivot leaves engineered with German hydraulic floor springs, magnetic perimeter gaskets, and concealed motorized closing hardware integrated with biometric building automation systems.
Global building codes—including EU energy directives and US ASHRAE 90.1—are mandating strict fenestration thermal thresholds. Aluminum cladding produced with low-carbon recycled aluminum billets (< 4.0 kg CO2/kg Al) and warm-edge insulated double/triple Low-E assemblies are transitioning from niche upgrades to mandatory contract specifications.
Severe typhoons across Southeast Asia, coastal cyclones, and extreme Gulf desert sandstorms demand higher baseline performance. Sourcing criteria are prioritizing verified wind pressure thresholds (e.g., AS 2047 N6 exceeding 4,500 Pa) and EPDM continuous extrusion seals that prevent water penetration under sustained wind-driven torrential rains.
Clear, technical explanations resolving logistics, customization, structural validation, and factory lead times for B2B cross-border purchasers.
Aluminum-clad wood doors combine an interior load-bearing timber frame (providing warmth, aesthetic prestige, and natural thermal insulation) mechanically bonded to an exterior heavy-gauge aluminum shield. The outer aluminum protects the wood from UV radiation, moisture, and pests, removing exterior timber maintenance entirely.
Yes. Over 85% of our production is made-to-order OEM/ODM fabrication. We produce extra-wide double doors and pivot systems up to 2.4 meters wide and 4.2 meters high. Our technical department supplies structural wind-load verification and sub-frame connection drawings prior to batch cutting.
Every door undergoes multi-layer protection: peelable protective surface film, dense corner foam bumpers, vacuum bubble encapsulation, and fully enclosed IPPC-certified solid fumigated plywood crates. Crates feature integrated bottom skids for smooth forklift handling on construction sites.
DERCHI doors are tested under Australian AS 2047 criteria, reaching the maximum N6 cyclonic rating. This validates that the profiles, corner assemblies, and glazing gaskets withstand serviceability wind pressures up to 3,000 Pa and ultimate limit state pressures exceeding 4,500 Pa with zero water leakage.
We partner with German hardware brands like Siegenia, Hoppe, and Roto, alongside heavy-duty commercial hydraulic pivot systems. Door leaves can be CNC-milled to integrate smart fingerprint access, facial recognition scanners, electric strikes, and hidden magnetic contacts for home automation.
Standard OEM/ODM lead times range between 25 and 35 calendar days following CAD shop drawing approval and color swatch sign-off. Expedited project schedules can be accommodated for critical commercial development deadlines.
Send your door schedules, opening dimensions (W × H), and architectural specifications. Our technical office returns structural CAD proposals and transparent FOB/CIF pricing within 24 hours.
