Custom Entry Door OEM/ODM Services

Precision architectural engineering, tailored extrusion configurations, and global supply chain support for commercial contractors, villa developers, and brand distributors.

Technical Capabilities

Customization & Engineering Vectors

Guangdong Dejiyoupin Doors and Windows Co., Ltd. collaborates directly with overseas architectural design practices and facade consultants to deliver structural performance, thermal efficiency, and tailored styling across all entry door types.

01

Engineering Calculations

Advanced structural simulation assessing localized wind loads, opening forces, and frame deflections. We evaluate project-specific criteria to specify optimal profile gauge and core structure.

02

Profiles & Thermal Breaks

High-tensile aluminum alloy, thermal-break barrier systems, and multi-cavity chambers. Finished with fluorocarbon (PVDF) or architectural powder coatings built to resist humid and coastal air.

03

High-Performance Glazing

Double and triple insulated glass units (IGUs) with Low-E technology, argon infill, ceramic frit patterns, acoustic PVB interlayers (STC ≥ 40), and solar reflective tints for optimal climate control.

04

Hardware & Security Locking

Strategic integration with Tier-1 architectural hardware manufacturers including WEHAG, Kerssemberg, HOPO, PAG, and VBH. Multi-point panic devices and heavy-duty concealed pivots.

05

Smart Access Automation

Concealed wiring chases compatible with commercial access control, motorized biometric pivot operators, RFID keypads, and building management protocols.

06

Climate & Code Compliance

Engineered to satisfy ASTM, CE, and regional standards (such as ABNT NBR and NCh), securing airtightness, thermal transfer limits (U-factor ≤ 1.0), and water infiltration protection.

Global Supply Chain

Supply Chain & Logistics Management

Leveraging 25+ years of international shipping experience, Guangdong Dejiyoupin Doors and Windows Co., Ltd. coordinates sea freight, customs packaging, and port documentation for zero-defect transit to South American and global ports.

1

Export Packaging

2

Port Clearance

Complete export documentation, bill of lading issuance, commercial invoices, packing lists, and certificate of origin preparation.

3

Ocean Freight

Direct containerized bookings via major ocean carriers with milestone tracking to destination ports like Santos, Callao, San Antonio, and Guayaquil.

4

Port Arrival Support

Smooth compliance and customs documentation coordination designed for local customs brokers and logistics expediters.

5

Site Delivery Care

Palletized and sequence-labeled door schedules ready for immediate offloading and staging directly at commercial and villa job sites.

Technical installation and structural alignment for architectural entry doors
Engineering Assurance

Precision Installation Dictates Product Longevity

Even premium structural doors experience operational degradation if anchoring, perimeter waterproofing, or frame squareness is compromised. Field misalignment accounts for up to 30% of thermal leakage and premature hardware strain.

Guangdong Dejiyoupin Doors and Windows Co., Ltd. provides comprehensive field guidelines, laser alignment benchmarks, and remote digital coordination to guarantee that on-site contracting teams execute factory-grade assembly every time.

Installation Protocol

Critical Field Installation Benchmarks

Structural Alignment & Squaring

Rigorous laser-leveling across rough structural openings combined with high-load non-corrosive shims eliminates framework torsion and ensures smooth swing mechanics.

Perimeter Acoustic Isolation

Dense perimeter dampening compounds, elastomeric acoustic membranes, and vibration-isolating anchors minimize sound flanking in high-noise city settings.

Triple-Layer Weatherproofing

EPDM weatherstripping, low-expansion polyurethane cavity insulation foam, and continuous self-adhering butyl flashing create an airtight, watertight building envelope seal.

Quality Sign-Off Protocols

Multi-point verification covering latch tolerances, weather seal contact continuity, and cycle testing confirms installation matches the approved engineering submittals.

Engineering FAQ

OEM/ODM Collaboration FAQ

Key technical and procurement answers for commercial developers, general contractors, and overseas distributors.

How quickly can I receive a customized technical proposal?
Submit your door schedule, elevation elevations, or CAD drawings to our engineering division. A dedicated project manager delivers a complete technical proposal, dimension schedule, and preliminary cost analysis within 1 to 2 business days. Video conferencing is readily scheduled to align directly on time-sensitive bids.
Can we evaluate product samples before placing bulk orders?
Yes. We supply physical corner corner-cut cross sections, powder-coated aluminum swatches, hardware mock-ups, and glass samples for architect and engineering sign-off. Clients may also inspect live mock-up assemblies through our 3D virtual tour and real-time factory video sessions.
How are custom oversized pivot and security doors crated for ocean shipment?
Custom oversized systems are crated in bespoke, heavy-duty fumigated plywood crates with internal EPE foam cushioning, reinforced corner braces, and waterproof barrier wraps to withstand rough maritime transport and multi-port transshipment.
