Directly addressing critical procurement questions from architects, general contractors, developers, and wholesale door distributors throughout Africa, North America, Australia, and the Middle East.
Direct Manufacturer Advantage
Guangdong Dejiyoupin Doors and Windows Co., Ltd. supplies certified architectural doors straight from our 180,000 ㎡ automated production facilities in Foshan, eliminating intermediary markups and guaranteeing transparent international code compliance.
Q1: Is DERCHI a direct door manufacturer or an intermediary trading company?
Guangdong Dejiyoupin Doors and Windows Co., Ltd. is a genuine tier-one direct manufacturer with more than 25 years of specialized expertise in the premium architectural opening industry.
Our production headquarters spans over 180,000 square meters, supported by 600+ skilled craftsmen, CNC machining centers, and R&D engineers. By managing raw material extrusion, fluorocarbon coating, precision welding, and export packaging in-house, we eliminate broker markups and offer factory-direct wholesale pricing, robust container logistics, and end-to-end OEM/ODM capabilities.
Q2: What is your primary product catalog for global projects?
We manufacture architectural entry and structural systems tailored to withstand coastal salt air, extreme tropical heat, and heavy wind loads across Africa and international territories:
• Aluminum Entry Doors & Pivot Systems: Heavy-duty architectural profiles, thermal-break engineering, concealed floor-spring pivot doors, and high-volume commercial storefront doors.
• High-Security Steel & Stainless Steel Doors: Multi-point locking security doors, bullet-resistant cores, and 304/316 grade stainless systems ideal for coastal environments.
• Cast Aluminum Luxury Entrances: Monolithic cast panels featuring three-dimensional relief patterns designed for villa estate main gates.
• Architectural Glass Doors: Insulated, double/triple tempered, and solar-control laminated glazing engineered for hospitality lobbies and luxury private estates.
• Automatic Garage Doors & Interior Timber Doors: Insulated overhead sectional garage doors and engineered interior acoustic/fire doors to support full-compound consolidation.
Q3: How do I request an accurate B2B wholesale quotation for my project?
Because our door schedules are engineered to measure, our pricing is optimized to match your specifications. To obtain an itemized project quotation within 24 hours, provide our technical desk with:
1. Architectural Drawings: CAD elevation files, architectural floor plans, or wall-opening schedules (width × height × jamb thickness).
2. Surface Finishing & Color: Architectural powder coating, PVDF fluorocarbon coatings, electrophoresis, or wood-grain transfer finishes.
3. Glazing Specifications: Single, double, or laminated Low-E safety glass, tinting requirements, or acoustic glass layers.
4. Hardware & Security Controls: German multi-point mortise locks, biometric smart handles, commercial panic bars, or automated floor pivots.
5. Delivery Port: Project destination city and sea port (e.g., Lagos Apapa, Tema, Mombasa, Durban, Dar es Salaam) for FOB or CIF quotations.
Q4: What is your standard manufacturing lead time and delivery schedule?
For standard architectural profiles, production lead time ranges between 25 and 35 working days following deposit confirmation and sign-off on detailed CAD shop drawings.
For custom oversized pivot systems, custom cast aluminum molds, or high-volume multi-unit commercial tenders, our production scheduling aligns with your phased construction schedule. Pre-assembly and dry-fit inspections are conducted at our factory prior to container packing.
Q5: What warranty coverage does Guangdong Dejiyoupin Doors and Windows Co., Ltd. provide?
Every commercial and residential export order is backed by a 10-year manufacturer quality assurance warranty.
This covers profile structural rigidity, anti-corrosion surface performance, mechanical hardware longevity, and weather seals against manufacturing defects under specified climatic environments. Replacement components and technical support are supplied directly via our international logistics desk.
Q6: What technical installation guidance and post-purchase support do you offer?
We ensure smooth jobsite execution from port clearance through post-handover operation:
• Technical Documentation: Detailed 3D installation videos, exploded assembly diagrams, and dimensioned structural anchor drawings.
• Real-Time Video Consultations: English-speaking facade engineers provide live video support for on-site leveling, smart lock wiring, and floor-spring calibration.
• On-Site Structural Teams: For large-scale developments, DERCHI can dispatch field supervisors to oversee installation teams and verify weather sealing.
Q7: Do your door systems comply with international building codes and import standards?
Yes. International compliance is fundamental to our export operations. Our product lines hold verified certifications including CE, ISO9001, AS2047 (tested to N6 structural cyclonic standards), and UL fire door listings.
For imports into African markets, we supply accredited laboratory test certificates, certified commercial invoices, and packing lists required by clearing agents to fulfill national pre-shipment verification programs such as SONCAP (Nigeria), KEBS PVoC (Kenya), and NRCS (South Africa).
Q8: How are doors packaged to prevent damage during containerized sea transit?
All doors undergo multi-layer export crating: protective PE film applied over finished aluminum faces, high-density EPE foam corner protectors, waterproof shrink film wrapping, and reinforcement inside non-fumigation plywood crates with internal timber bracing. This safeguards door geometries, glass, and surface finishes throughout ocean transit and terminal handling.
