Examine our certified export series engineered for high-security residential villas, commercial entrances, and multi-family infrastructure projects worldwide.
The global architectural envelope sector is undergoing a structural transition. For decades, commercial and high-end residential real estate developments relied heavily on unreinforced cold-rolled steel or solid hardwood assemblies for security perimeter protection. However, modern environmental pressures, stringent municipal energy efficiency codes (such as California Title 24, European EN 14351-1, and Australian National Construction Code regulations), and the demand for slim architectural sightlines have rendered traditional door systems obsolete.
As a global leader in OEM security door manufacturing, DERCHI Doors and Windows operates a state-of-the-art 180,000 m² industrial production campus in Foshan, China. We specialize in engineering high-performance aluminum alloy security doors, cast aluminum armored entrance systems, and heavy-duty structural pivot doors that resolve the historical compromise between high-level physical physical protection, thermal breaking efficiency, and structural durability.
OEM Information Gain Insight: Unlike standard steel doors that corrode in humid environments or traditional timber doors prone to swelling and frame warping under high solar thermal loads, 6063-T5/6005-T6 extruded aluminum security doors maintain dimensional stability across thermal spectrums ranging from -30°C to +80°C, while providing physical intrusion resistance rating up to RC3 and RC4 European standards.
Utilizing high-tensile cast aluminum panels (6mm–12mm thick) combined with integrated steel armor plates, multi-point lock housings, and anti-drill manganese plates to neutralize physical attacks, leverage tools, and mechanical impact.
Engineered with PA66-GF25 glass-fiber reinforced polyamide thermal break profiles, filling multi-chamber interior cavities with high-density polyurethane (PU) insulation to achieve U-values low as 1.6 to 1.8 W/(m²·K).
Triple-sealed continuous EPDM gasket systems coupled with laminated soundproof insulating glass units (6mm + 1.52PVB + 6mm / 12A / 6mm) isolate urban traffic noise, coastal wind hums, and industrial ambiance.
Comprehensive physical property comparisons across DERCHI's proprietary OEM product lines. Designed to assist architects, structural consultants, and procurement managers in drafting accurate project specifications.

Derchi integrates automated precision machinery, computer-controlled thermal transfer systems, and digital quality control locks to produce world-class security door assemblies.
Hardware pocketing, lock mortising, and hinge positioning are executed on German-imported 5-axis CNC machining centers to maintain fabrication tolerances within ±0.2mm across entire 4000mm door leaves.
Automated powder coating and PVDF liquid spraying lines ensure coating adhesion exceeding 100/100 cross-hatch tape test standards, guaranteeing 20-year color retention under extreme solar UV exposure.
OEM customization allows seamless embedding of smart biometric locksets, 3D facial recognition cameras, motorized multi-bolt locking, and home automation systems (Zigbee/Matter/KNX protocols).
Every international market demands precise compliance with regional building standards, structural wind codes, and thermal envelope criteria. DERCHI engineers custom door schedules tailored to local jurisdiction mandates.

From raw 6063-T5 aluminum billet extrusion to final ocean freight containerization, DERCHI maintains rigorous internal quality checkpoints at every production phase.
Spectrographic analysis verifies chemical composition of raw aluminum billets before extrusion to ensure required tensile and yield strength.
Laser cutting, CNC milling, continuous robotic corner welding, and manual metal-finishing ensure flawless geometric alignment.
Sampling batches undergo water spray penetration tests under positive wind pressures, structural deflection, and multi-lock cycle fatigue testing.
Full EPE foam wrap, corner protectors, multi-layer corrugated boxes, and sealed fumigation-free plywood crates prevent maritime transit damage.

In-depth technical answers provided by DERCHI senior structural engineers to address critical purchasing, engineering, and compliance inquiries.
We primarily utilize 6063-T5 and high-tensile 6005-T6 architectural grade aluminum alloys. The 6005-T6 alloy provides exceptional yield strength (up to 240 MPa) and shear resistance, making it ideal for structural pivot door frames and heavy security leaves carrying oversized impact glass panels.
Our pivot security door series incorporates concealed multi-point locking rods that throw steel bolts into top and bottom structural headers simultaneously. Additionally, the hinge side utilizes continuous interlocking anti-prying profile grooves, rendering crowbar separation impossible even if pivot pins are compromised.
Standard OEM production accommodates door leaf dimensions up to 1,600 mm in width and 3,200 mm in height. For custom architectural villa gates and commercial lobby entrances, our heavy-duty floor-pivot hardware system allows leaf dimensions up to 2,000 mm × 4,000 mm with a total door leaf weight rating up to 500 kg (1,100 lbs).
For coastal or high-salinity marine environments, we recommend PVDF (Fluorocarbon) liquid spraying (minimum 3-coat system) or Qualicoat Class 2 / Class 3 certified powder coating. These treatments pass 2,000-hour neutral salt spray (NSS) chamber testing without blistering, pitting, or film breakdown.
Yes. Our in-house engineering team provides detailed 2D CAD shop drawings (DWG/PDF), structural elevation cross-sections, anchoring detail sheets, and 3D BIM (Revit) objects within 24–48 hours upon receipt of project schedule details.
Engineering sample production takes approximately 12–18 days. Bulk container project orders are completed within 25–35 days after CAD approval and deposit confirmation. DERCHI does not enforce a rigid Minimum Order Quantity (MOQ) for project orders; sample single-unit trial orders are welcomed for testing and mock-up verification.
Whether you are an architect submitting tender documents, a hardware distributor seeking exclusive OEM partnership, or a contractor executing a luxury residential community, DERCHI delivers precision door engineering tailored to your standard.
