FAQ

Guangdong Dejiyoupin Doors and Windows Co., Ltd. is a premier direct manufacturing brand with over 25 years of specialized engineering in luxury entrance systems, heavy-duty pivot doors, and architectural facade openings. Operating from our industrial production base covering over 70,000 m² to 180,000 m² in Foshan, Guangdong, our enterprise employs over 600 skilled technicians, CAD draftspersons, and quality control engineers.

By engaging directly with our manufacturing headquarters, overseas buyers eliminate intermediary trading commissions, protect architectural design integrity, and obtain stable export delivery schedules with verified factory-direct wholesale pricing.

Our product portfolio is engineered specifically to withstand challenging climatic conditions—including coastal saltwater air, intense monsoonal rains, and desert thermal shifts—while adhering to global architectural codes:

• Aluminum Entry Doors & Systems: High-tensile thermal-break aluminum doors, minimalist slim-profile glass systems, and high-traffic commercial entrance solutions.

• Pivot Doors & Cast Aluminum Entrances: Oversized grand pivot entries, solid cast aluminum doors with deep 3D sculptural reliefs, termite-proof, warp-free structural builds.

• Stainless Steel Security Doors: Marine-grade 304 and 316 anti-corrosion stainless steel entrance doors equipped with heavy-duty multi-point perimeter locks.

• Commercial Glass Facades & Automated Garage Openers: Structural glass systems alongside insulated sectional rolling garage solutions designed for multi-car villa estates and luxury developments.

Because every architectural opening requires custom engineering according to wind load, opening dimensions, and local thermal specifications, we generate exact cost estimates within 24 business hours upon receiving your project schedule:

1. Dimensional Schedules: Structural rough opening sizes (width, height, wall thickness) or architectural CAD/PDF elevation drawings.

2. Profile & Surface Finishes: Fluorocarbon PVDF coatings, marine-grade powder coating, anodized metallic tones, or high-durability thermal wood grain transfers.

3. Glazing Specifications: Double or triple low-E insulated glass units, laminated cyclone safety glass, fluted architectural privacy glass, or tinted safety panes.

4. Locking Hardware & Automation: Heavy-duty commercial German pivot hinges, multi-point mortise locksets, or smart biometrics (fingerprint, RFID, facial recognition).

Standard architectural entry door configurations undergo full factory fabrication and quality inspection within 25 to 35 business days following formal sign-off on shop CAD drawings and deposit receipt.

For large-scale commercial tenders or bespoke oversized pivot doors, flexible multi-container production scheduling is arranged to synchronise precisely with your on-site building milestones. All shipments leave ports with complete ocean freight documentation, Fumigation Certification, and Certificates of Origin.

Guangdong Dejiyoupin Doors and Windows Co., Ltd. backs each international export shipment with a comprehensive 10-Year Quality Assurance Warranty. This coverage protects against structural deformation, extrusion alloy degradation, weld integrity loss, and premature surface delamination or discoloration under regular environmental exposure. Mechanical pivots and hardware mechanisms carry full replacement guarantees.

Seamless on-site execution is guaranteed across borders through our dedicated remote and on-site engineering services:

• High-Resolution 3D Installation Guides: Comprehensive CAD diagrams and step-by-step videos covering anchor positioning, threshold flashing, and compression gasket seals.

• Live Video Engineering Support: Real-time remote technical calls between your site contractors and our senior factory engineers to guide pivot centering, mortise alignment, and automation setup.

• Heavy Export Packaging: All units are protected with protective film wrap, impact-resistant corner cushions, and reinforced multi-ply fumigated wooden crates built for ocean freight transfer.

Yes. Rigorous technical verification forms the core of Guangdong Dejiyoupin Doors and Windows Co., Ltd.'s global export operations. Our product lines are certified and tested to comply with international requirements:
