Explore high-performance entry systems customized for commercial developments, residential luxury villas, and wholesale distributors worldwide.
In contemporary B2B architectural procurement, the entrance door has evolved from a passive security barrier into an active component of high-efficiency building envelopes. Modern zero-energy standards, LEED v4 certifications, and strict international building energy codes (such as IECC, California Title 24, and Europe’s EN ISO 10077) have raised performance benchmarks for exterior entry systems.
Standard aluminum is a natural thermal conductor. DERCHI engineered doors feature continuous polyamide (PA66-GF25) thermal breaks that structurally sever internal and external aluminum frames, curbing thermal bridging and condensation.
Fabricated using 6063-T5 architectural-grade aluminum extrusions with wall thicknesses up to 3.0mm, DERCHI doors incorporate heavy-duty multi-point locksets and anti-pry strike plates.
Our automated finishing lines provide superior environmental protection against salt spray corrosion, UV radiation, and mechanical abrasion in coastal and desert zones.
A detailed evaluation of DERCHI insulated aluminum entry door systems against key international performance standards.
| Performance Indicator | Test Standard Reference | DERCHI Insulated Aluminum Door Value | B2B Architectural Benefit |
|---|---|---|---|

| Water Penetration Resistance | ASTM E331 / AS2047 | Static: 600 Pa / Dynamic: 3,000 Pa | Eliminates rainwater ingress during severe storm and hurricane conditions. |
| Acoustic Insulation (STC / Rw) | ISO 140-3 / ASTM E90 | 35 dB - 42 dB Reduction | Protects luxury interior environments from urban and highway ambient noise. |
| Structural Wind Load | AS2047 N6 / ASTM E330 | Up to 4,500 Pa Design Pressure | Engineered for high-wind coastal villas and commercial entry towers. |
| Security & Forced Entry | EN 1627 RC2 / RC3 Standard | Multi-Point European Hook Locks | Commercial-grade anti-prying protection for high-value properties. |
How DERCHI solves supply chain bottlenecks, custom specs, and compliance hurdles for overseas project developers, importers, and hardware distributors.
Extensive flexibility in frame profile depth (80mm to 120mm), sidelight integration, oversized leaf dimensions up to 2000mm x 4000mm, and smart biometric lock integrations.
Our in-house design engineers supply full CAD detail elevations, section cuts, and BIM Revit files for seamless integration into architectural design workflows before production starts.
Factory orders shipped with complete CE certification packages, ISO 9001 quality audit reports, and AS2047 / NFRC laboratory test summaries for frictionless local inspections.
All door leaves are encased in protective film, EPE foam edge protectors, 5-layer heavy-duty cartons, and sealed inside fumigation-free wooden crates to keep transit damage under 0.3%.
DERCHI continuously invests in intelligent manufacturing, energy-saving material innovations, and integrated smart access hardware.
Integrating thin-profile nanoporous aerogel blankets inside aluminum door leaf cores to reach ultra-low U-factors (<0.8 W/m²K) without increasing overall door thickness.
Seamless embedding of hidden motor drives, facial recognition panels, 3D palm-vein scanners, and smart home automation integration (Zigbee/Matter protocols) inside thermal break frames.
Upgrading Foshan manufacturing facilities with 6-axis precision welding arms and dynamic sealant dispensing robots to maintain strict tolerances within ±0.3mm across large volume production.
Explore our complete product ecosystem featuring cast aluminum gates, stainless steel safety doors, soundproof bifold patio openings, and large glass pivot doors.
Clear, definitive engineering answers for developers, builders, and wholesale door importers.
Our insulated aluminum entry systems are manufactured under strict ISO 9001 certified protocols and comply with CE marking (EN 14351-1), Australian AS2047 / AS1288 standards, and North American NFRC thermal performance ratings. Third-party test reports covering air infiltration, water tightness, and structural wind pressure are provided with every official B2B quotation.
We utilize high-grade polyamide PA66-GF25 thermal break strips ranging from 24mm to 34mm in depth, combined with high-density polyurethane (PU) or aerogel door panel core insulation. Double EPDM gasket seals around the frame perimeter eliminate cold air leakage and prevent internal surface condensation.
Engineering sample orders are completed in 12 to 18 days. Full bulk project orders average 25 to 35 business days following CAD drawing sign-off and color matching approval. DERCHI supports flexible project sourcing with no strict container MOQ for architectural orders, allowing sample door units for showroom evaluation or field testing.
Yes. We specialize in custom oversized single and double leaf pivot and swing doors up to 2000mm in width and 4000mm in height. Oversized systems feature internal high-strength steel sub-cores, German-engineered heavy-duty hydraulic floor pivots rated up to 500kg load capacity, and multi-point locksets.
For severe coastal environments, we recommend PVDF (fluorocarbon) three-coat finishes or anodized coatings certified to withstand 3,000+ hours of neutral salt spray testing without surface degradation, chalking, or fading. Standard powder coatings from AkzoNobel or Tiger Drylac are also offered in full RAL color spectrums.
Absolutely. Our specialized technical engineering team creates complete 2D CAD shop drawings, 3D section detail diagrams, and BIM Revit families matching project specifications. CAD drawings are issued within 24–48 hours of initial inquiry for architect review and structural stamping.
